abstract = {Coastal ecosystem engineers, such as mussels, oysters, salt marsh grasses, and seagrasses, typically shape their environment by ameliorating stressors when they grow beyond a critical population size. In doing so, they not only facilitate themselves but also provide habitat for diverse communities, which in turn, can engage in reciprocal interspecific facilitation. Over the last decades, anthropogenic disturbances have caused rapid degradation of coastal ecosystems, emphasizing the need for their restoration. Although the importance of both inter- and intraspecific positive interactions has been confirmed in small-scale experiments, their combined potential remains to be tested in restoration-scale experiments. Here, we examine whether restoration aimed at simultaneous recovery of both facilitation types can increase restoration yields of the seagrass Zostera marina. We conducted a full factorial experiment by manipulating patch size to test for intraspecific facilitation effects and co-introduced the epiphyte-grazing snails Littorina littorea to investigate interspecific facilitation. We found that the effect of including intraspecific facilitation on restoration yields was highly dependent on the hydrodynamic exposure conditions at the restoration site. Large patches in the most exposed sites showed a 40% increase in seagrass restoration yield compared to small patches, while at sheltered sites, large patches counted up to 60% less surviving plants compared to small ones. Interspecific facilitation, on the other hand, increased success yields by 73% on average. Moreover, in some plots where L. littorea survived through the winter, we counted 20 times more shoots than plots without co-introduction. Our study is the first to demonstrate that co-introduction can serve as a successful large-scale restoration strategy. Additionally, we highlight that integration of both inter- and intraspecific facilitation into restoration designs can be a powerful approach to increase coastal restoration success. However, we emphasize that these strategies should be applied specifically to counter environmental stressors as they may have adverse effects themselves in environments without such stressors.},

abstract = {Praxelis clematidea is a noxious invasive weed. Understanding the dispersion trends and niche changes inherent to P. clematidea will be helpful for monitoring this invasive species and for providing early warnings of its spread and developing appropriate scientific prevention and control measures. In this study, the invasion risk zones of P. clematidea in Guizhou Province were classified via MaxEnt, Zonation, and ArcGIS. The dispersion trend was predicted, and the ecological niche change was quantified via the R software ecospat package. The results revealed that (1) the current high-risk areas for P. clematidea invasion in Guizhou cover 14,096.03 km[2], concentrated mainly in the western to southern regions (Liupanshui, Anshun, Qianxinan, and Qiannan); the medium-risk areas cover 21,144.04 km[2], concentrated mainly in the southwestern region (Anshun, Qiannan); and the low-risk areas cover 26430.05 km[2], occurring in all cities of Guizhou but concentrated mainly in the small areas outside the high- and medium-risk areas. (2) From the present until the 2050s, the risk areas of P. clematidea will expand mainly toward the southeastern parts; from the 2050s to the 2070s, the risk areas will decrease in the southeast; and from the 2070s to the 2090s, they will expand at a large scale in the central and northeastern parts. Overall, the trend is toward expansion. (3) The degree of ecological niche overlap between P. clematidea in Guizhou Province and its original habitat is very low (Schoener's D= 0.12); the rates of niche expansion, stability, and underfilling are 0.88, 0.12, and 0.96, respectively, indicating niche instability. P. clematidea invades and occupies areas with relatively high precipitation during the warmest season in Guizhou Province. Compared with the temperature preferences in the coldest season in the original area, this species can adapt to low temperatures.},

This study aimed to assess the resistance of native species to invasive species in plant communities with varying species densities, focusing on growth traits and soil properties under the influence of different soil pollutants. Four native experimental communities varying in number of species were established, with each community paired with a distinct invasive species., i.e., C1 (four natives, i.e., Lactuca indica L., Plantago asiatica L., Leonurus japonicus Houtt., Alternanthera sessilis L. + Symphyotrichum subulatum (Michx.) G. L.), C2 (four natives, i.e., L. indica, P. asiatica, L. japonicus, A. sessilis + Sphagneticola trilobata L.), C3 (five natives, i.e., L. indica, P. asiatica, L. japonicus, A. sessilis, Hemistepta lyrata (Bunge) + S. subulatum), C4 (five natives, i.e., L. indica, P. asiatica, L. japonicus, A. sessilis, H. lyrata + S. trilobata). These communities were exposed to four soil pollutant treatments: (i) no pollutants (CK), (ii) PE microplastic particles (MP), (iii) cadmium, representing a heavy metal (HM), and (iv) both MP + HM. An ANOVA showed that MP, HM, and MP + HM significantly affected the biomass of both native and invasive species across all four communities (P < 0.05). Furthermore, microbial biomass carbon, nitrogen, and CO2 emissions were higher in C2 and C4 soils (invaded by S. trilobata) than in C1 and C3 soils (invaded by S. subulatum). The invasion resistance index (IRIN) of the native species increased in C1 compared to C2 by 74.50, 49.86, 18.34, and 24.72% under CK, MP, HM, and MP + HM treatments, respectively. Similarly, the IRIN in C3 increased relative to C4 by 48.30, 30.45, 22.56, and 31.03% under the same treatments. The study concludes that invasion resistance of native species depends on species diversity, the specific invasive competitor, and the type of pollutant.},

abstract = {The homogenization of landscapes through the introduction of large-scale farms, the decline of biodiversity conditioned by high summer temperatures and dry weather, as well as the expansion of alien species determine the monodiet feeding of honeybees. In this study, we investigated the effect of monopollen feeding regimens (containing hazel, rapeseed, pine, buckwheat, Phacelia, and goldenrod) on the activity of the proteolytic system in the tergite 3, tergite 5 or sternite apian fat body, and hemolymph. We showed that pollen from rapeseed, Phacelia, buckwheat, and goldenrod increased the activities of acidic, neutral, and alkaline proteases and their inhibitors in the fat body and hemolymph when compared to the group fed with sugar candy only. The activities of proteases and their inhibitors in bees fed with pollen from hazel and pine were usually higher compared to the activities of honeybees fed with sugar candy only, but lower than in workers fed sugar candy with the pollen of entomophilous plants. Moreover, when comparing the proteolytic system activity between localizations/segments, the highest values were observed in tergite 5, regardless of what age the bees were and whether they were fed candy with added pollen. It is important to understand the impact of individual types of pollen in the context of potential future monodiets. Furthermore, the beneficial impact of Phacelia pollen to drive the rise of protease and protease inhibitor activities, helping to counteract negative environmental factors, can be supported by introducing, for example, flower mixtures for the insects or pollen-supplemented sugar candies for bees during periods without access to pollen.},

Aedes albopictus (Skuse) (Asian tiger mosquito) is a rapidly spreading invasive species responsible for transmitting serious diseases, including dengue. In the present study, we evaluated eugenol's larvicidal activity against A. albopictus larvae and its impact on the non-target larvivorous fish, Trichogaster fasciata. Eugenol showed larvicidal activity with an LC50 of 149.89 ± 17.38 ppm, while clove oil had a lower LC50 of 77.11 ppm at 24 h. Eugenol exposure resulted in notable larval morphological changes, including melanization of the thorax and anal papillae. Histopathological analysis revealed toxic effects of eugenol on the peritrophic membrane, epithelial layer and microvilli of the larval midgut after 24 h. We also assessed the acute toxicity of eugenol on T. fasciata over 96 h using LC10, LC25 and LC50 concentrations. LC10 and LC25 concentrations were safe for the fish, but LC50 caused immediate mortality. Remarkably, LC25 concentration restored the natural pigmentation of T. fasciata, which had been lost in aquarium acclimatized conditions. Histopathological examination revealed normal gill and liver features in fish exposed to LC25. In an integrated model, eugenol at LC25 effectively killed A. albopictus larvae and did not harm the non-target larvivorous mosquito Toxorhynchites splendens Theobald and fish T. fasciata. Thus, eugenol (LC25) shows promise for controlling A. albopictus larvae in small aquariums and nursery ponds, alongside beneficial larvivorous species.},

In tropical islands, despite their growing extent, urban areas are less explored and sampled compared to natural areas.

This study investigates the diversity and ecological characteristics of the wild bee community and its temporal dynamics in the Havana province of Cuba. Cuba is a biodiversity hotspot in the Caribbean and hosts the highest bee biodiversity in the Antilles. Here, we analyzed 1,322 records (of which 1,067 new) from various sources (online databases, literature, and historical natural collections during the XIX Century). In the studied area our data attest the presence of 52 species (23 genera, 4 families), of which 47 are native (14 endemics) and four are introduced species Three species categorized as "critically endangered" for the country were recorded; 41 species are polylectic (78.8%) and 11 kleptoparasitic (21.2%). Most species were found during the rainy season (49 species vs 39 species recorded in dry season). Regarding the variation of the wild bee population over the years, one third of the recorded species have not been observed since the last century, while about 70% of the species persist. Analysis of a century data underscores the importance of conserving the wild bee community in these provinces.},

abstract = {The need to develop optimal restoration protocols for degraded grasslands has led to experimental research aimed at determining how different restoration treatments influence outcomes for biodiversity. The magnitude and direction of diversity responses to restoration treatments may depend on the spatial scale at which diversity is measured (local, regional), the metric of diversity used (Hill numbers), and the facet of diversity (taxonomic, functional, phylogenetic) considered. We conducted a long-term factorial experiment in a degraded grassland in Missouri, USA, in which we experimentally applied a regionally appropriate biodiverse seed mixture, added soil nutrients to restore soil fertility, and varied the timing in which the invasive plant Lespedeza cuneata entered the community. We used a unified framework of Hill numbers to evaluate how treatments influenced diversity, considering different spatial scales, metrics, and facets (taxonomic, phylogenetic, functional). We find that the timing in which the invasive L. cuneata entered the community had large effects on diversity, while nutrient addition had more limited effects. This was driven by the high dominance of the focal invasive when allowed to invade early in the growing season, suppressing diversity. The positive effects of late invasion increased in magnitude with spatial grain and were higher for taxonomic than phylogenetic and functional facets of diversity. This was largely due to the dominance of the focal invasive, negatively affecting diversity within specific plant families or functional phenotypes across treatments. Under early invasion, nutrients had a negative effect, particularly at local scales, inflating beta diversity in this treatment and resulting in negative to no effect of late invasion on many aspects of beta diversity. Our results demonstrate the importance of looking at a multitude of different measures of diversity to understand the relative effects of ecological restoration treatments combined with invasion timing. Efforts to keep noxious plant invaders out of a system early in restoration approaches better allow desirable, native plants to establish and can have long-term benefits for multiple aspects of diversity.},

Although numerous studies have reported product development and model accuracy, few have evaluated these tools in practical environments beyond developmental settings. In this study, we developed a weed detector using the You Only Look Once (YOLO) v3 object detection algorithm to identify six noxious weed species. Specifically, we examined the effects of: (i) image collection locations, (ii) target backgrounds, and (iii) camera devices on detection accuracy, assessing applicability through field verification at 68 sites across Japan and controlled garden experiments.

RESULTS: Detection success was influenced by the background of the target species in images, with significant interaction effects observed between background and target species on detection outcomes. In the most affected combination (background: tray; species: Ipomoea lacunosa), the average precision (AP) value decreased by ~0.2 compared with the other conditions. AP values in field tests were lower than those from test data resembling training data, with no correlation between AP values from test data sets and field verification. No clear effects of land use or camera devices on detection success were detected.

CONCLUSION: This study highlights the importance of background in image-based weed detection and identifies limitations in detector applicability. Our findings are expected to support more-efficient development and underscore the importance of sharing applicability data for improved weed detection tools. © 2025 Society of Chemical Industry.},

This study evaluated the efficacy of the native AM fungus Funneliformis mosseae in the establishment (3 months) of seedlings of the invasive species Nicotiana glauca R. C. Graham in a semiarid soil contaminated by several heavy metals (HMs), under ambient and elevated levels of CO2 (420 vs. 760 ppm, respectively) and without fertilizer treatment. Thus, we tested the effect of this native AM fungus on the plant growth parameters, the percentage mycorrhizal colonization of roots, bioavailability of HMs in soil, accumulation of HMs in plant, soil structural stability, and the functions of microbial communities (soil enzyme activities) in the rhizosphere of N. glauca in response to elevated CO2. The mycorrhizal inoculation with F. mosseae and elevated CO2 increased synergistically the shoot (about 150 %) and root (about 53 %) dry biomass and shoot P content of N. glauca. Mycorrhizal inoculation was effective in reducing the bioavailability of toxic HMs in the soil, particularly Cd, Cu, and Zn, as well as shoot Cu uptake, and resulted in shoot bioconcentration factors for all metals lower than 1, regardless of the atmospheric CO2 level. Meanwhile, the native AM fungus increased soil biomass C content, dehydrogenase, protease, and alkaline phosphomonoesterase activities, soil aggregate stability, and extractable K. In conclusion, this approach reduces metal mobility and improves soil microbial functioning and structural stability, enhancing long-term soil recovery in climate-stressed mining areas.},

While calling is crucial for anuran breeding and communication, the coping mechanisms of city dwelling and cosmopolitan species in urbanized environments remain understudied. Given that invasive species have higher environmental adaptability than native species (because of habitat specificity and environmental sensitivity), we studied the calling patterns of the invasive American bullfrog (Aquarana catesbeiana) in different levels of urbanized areas in South Korea. In our study, we found an early onset of calling activities in urbanized A. catesbeiana populations, which suggests a change induced by factors related to urbanization on breeding phenology. Additionally, urban populations show more intense diurnal calling activities but shorter breeding periods than non-urban populations. The results indicate water temperature and urban noise as the leading factors influencing calling activities in A. catesbeiana. Urbanization induced changes in breeding and calling activities might have facilitated A. catesbeiana to invade and establish populations outside their natural ecological niches. Thus, this study sheds light on the effect of urbanization on frog breeding activities and how an invasive species copes with modified environments in new areas.},

Its potential in disseminating biodiversity conservation information has not been well assessed, especially in Africa, a biodiversity hotspot. When such assessments are conducted, they are usually species-specific, activity-based, or localized, making broader generalizations difficult. We evaluated the viewership and interaction of the videos posted about Africa across different organism groups, countries (geopolitical units), geographical regions, ecoregions, and channels (content creators). We assessed 431 videos, which collectively garnered 32,630,126 views, 364,700 likes, and 48,839 comments across 274 channels, five regions, and 31 African countries. The mean daily views varied significantly across countries, regions organism groups, and channels. Notably, more views per day were from biodiversity-rich countries, such as Madagascar, and most videos were posted from South Africa. Government and academic institutions posted fewer videos than individually owned and international biodiversity-related non-governmental organization (NGO) channels. Also, most channels posting about African biodiversity are based in the United States of America. Increased attention to biodiversity through social media engagement will likely stimulate external funding, international collaborations, policymaking, and participatory programs, benefiting both the public and organizations such as NGOs and governments. We observed a great need for increased participation by African-based content creators, primarily by government institutions, to effectively adopt a strong social media strategy to communicate information about biodiversity conservation, especially to the growing online population.},

abstract = {PREMISE: Plants from regions where fire is a novel disturbance typically lack fire-adaptive traits, which may explain the post-fire invasion by alien plants from fire-prone ecosystems. Unlike many Mediterranean-type ecosystems, the Chilean matorral has a limited evolutionary history with fire. We predict that a negative germination response to fire will be more frequent in its native flora than in alien plants, most of which originate from the fire-prone Mediterranean Basin.

METHODS: We compiled a database on the germination responses to fire cues of 70 native and alien plant species from the Chilean matorral using published studies and unpublished data from our own experiments. We then compared the frequency of these responses between native and alien species using generalized linear mixed models.

RESULTS: Negative responses to heat shock were more probable in native than in alien species, while there were no differences in the probability of negative responses to smoke. Species origin did not affect the probability of positive responses to fire cues. When only annual plants were considered, natives and aliens did not differ in their germination responses to fire cues.

CONCLUSIONS: Our findings suggest that the influence of post-fire germination on invasion processes in the Chilean matorral is better explained by the negative effects of heat on the germination of native species (which lack fire-adaptive traits) than by the positive response of alien species to fire cues. The reduced germination of natives creates opportunities for alien species establishment, rather than pre-existing fire adaptive traits driving invasion success.},

Tristerix corymbosus (Loranthaceae) is a native generalist hemiparasite in Chile but infests many nonnative tree species and appears to suppress them more than its native hosts, indicating its potential to provide substantial ecological resistance. These patterns suggest the novel phenomenon of native hemiparasite host switching from slow-growing native hosts to fast-growing nonnatives, which may provide substantial biotic resistance to invasion, but they also have fascinating ecological, physiological, and evolutionary implications. For example, resistance to invasion contrasts with traditional views of parasitic plants as forest plagues. Instead, Tristerix may function in invaded forests as a keystone species with negative direct effects on invaders and positive indirect interactions with natives. The negative effects of Tristerix on nonnative species provide a more complete understanding of the various roles native parasitic plants can have in resistance to invasion.},

abstract = {Plant invasions are biogeographical phenomena that may involve shifts in belowground plant-fungal interactions, such as the release from fungal pathogens or more beneficial interactions with mutualists in nonnative ranges. However, native and nonnative ranges are not uniform but environmentally heterogeneous, and plant-fungal interactions are strongly shaped by spatio-environmental context. Intense discussion at the 45[th] New Phytologist Symposium revealed that we lack information on how well spatio-environmental variation within ranges has been considered in samplings and analyses of studies comparing plant-fungal interactions between ranges. Through a systematic review, we assessed the sampling quality of recent biogeographical studies. We found that the majority relied on a limited population sampling within each range, often covering only a small fraction of the species' spatial distribution and macroclimatic niche. Additionally, low similarity between the sampled climatic gradients in the native and nonnative ranges might have introduced false-positive differences across ranges. These sampling deficiencies may undermine the robustness and representativeness of range comparisons, thereby restricting our ability to accurately assess the role of plant-fungal interactions in invasion success. We recommend that future research incorporate broader and more comparable spatio-environmental variation in both ranges, and we provide practical guidelines for improving sampling designs.},

abstract = {This study aims to identify the structural and compositional differences between native and exotic woodlands on Terceira Island, Azores. Based on landscape, habitat, and microhabitat analyses, remnants of native forests appeared to be associated with less accessible terrains. A more homogeneous structural complexity is exhibited, derived from the numerous branching patterns of the endemic vascular plant species. In contrast, exotic forests exhibit structural heterogeneity driven by mixed non-indigenous vascular plant species as a result of human actions such as afforestation and latter invasion of exotic tree species, after abandonment of the agricultural use. The ground and canopy layers in exotic forests were more invaded by non-indigenous species, while the understory demonstrated greater resilience by being mostly composed of indigenous species. Our findings highlight the structural and ecological differences between native and exotic woodlands, reflecting the historical transformation of forest cover in the Azores. These insights emphasize the importance of long-term monitoring and structural assessments in informing conservation efforts aimed at preserving native forests and managing invasive species in exotic woodlands.},

As the global hotspot for non-native reptiles and amphibians, South Florida's herpetofaunal community provides a unique opportunity to study native/non-native community dynamics. In addition, despite high levels of development and habitat loss, South Florida has a network of protected natural areas, allowing insight into the impacts of natural vs. anthropogenic areas on native and non-native richness and abundance. Surveys conducted in Miami-Dade County in 2017 demonstrated that non-native species already dominated both natural and anthropogenic parks and provided a baseline to examine dynamic changes in the community. In 2022, we replicated the surveys from 2017 at the same 30 sites. We found that non-native richness and abundance have increased significantly (19% and 33% increase in overall alpha diversity and abundance, respectively) in just 5 years' time. We found no correlation between these non-native increases and decreases in either native species richness or abundance. Notably, non-native species richness increased more rapidly at anthropogenic sites, with two rock-loving species, Agama picticauda and Leiocephalus carinatus, standing out as the most rapidly spreading non-native herpetofauna. Our findings demonstrate that there is continued expansion of non-native herpetofaunal populations even in the highly invaded community of Miami-Dade County and that protection of natural habitat may help slow the spread of non-native species.},

This study investigates the tripartite interaction between E. adenophorum, its obligate phytophagous insect Procecidochares utilis, and the insect's enteric microbiota. We isolated Kluyvera ascorbata SZLYS-22, a gut-associated bacterium from P. utilis larvae, demonstrating potent herbicidal activity against the host plant. Bioactivity-guided characterization identified methyl indole-3-acetate (MeIAA) as the principal phytotoxin, exhibiting concentration-dependent inhibition of seed germination and induction of systemic morphological aberrations including stem spiralization, petiole epinasty, and eventual plant mortality. Histological examination revealed MeIAA-induced cytological disorganization in vascular tissues, manifesting as cellular pleomorphism and expanded intercellular lacunae. Transcriptomic profiling revealed significant down-regulation of phenylpropanoid pathway genes (PAL, 4CL, LiP), corroborated by enzymatic assays showing lignin reduction versus control. Paradoxical up-regulation of C4H expression suggests compensatory feedback mechanisms insufficient to maintain lignification. These findings establish MeIAA as a novel bioherbicide disrupting lignocellulosic integrity through targeted pathway modulation. Furthermore, this work elucidates the evolutionary arms race between E. adenophorum and P. utilis, highlighting the underappreciated role of insect-associated microbiota in mediating plant-insect interactions. The results provide a framework for developing microbiome-informed biocontrol strategies.},

They face acute impacts such as pollution from shipping accidents, chronic pollution from point sources, run-off and catchments plus disturbances by food gathering, recreation and sediment deposition in sheltered areas. Coastal urbanisation can both impact natural shores and create impoverished artificial rocky shores. Superimposed upon local and regional scale impacts are global environmental changes including warming, sea-level rise, increasing storm frequency, ocean acidification and non-native invasive species. Rocky shores are, however, amenable to long-term ecological monitoring and ecological experimentation. Thompson, Crowe and Hawkins (2002) reviewed anthropogenic impacts on rocky intertidal habitats and forecasted their status for the next 25 years. The paper was critiqued by invited experts (Branch, Castilla) at a subsequent conference in 2003 (Environmental Future of Aquatic Ecosystems, Zurich, 23-27 March 2003), culminating in a consensus chapter in Aquatic Ecosystems: Trends and Global Prospects (Branch et al., 2008). Nearly 25 years later, we revisit and evaluate their predictions to explore implications for the next 25 years as new potential impacts emerge in parallel with societal attempts to transition to net zero carbon outputs. An update is provided on what was largely correct (oil-spills, food harvest, invasive species, sedimentation/run-off, organotins, global-change, artificial habitats, recreation/research/education) and what was partially/completely wrong (eutrophication, aquaculture/GMOs, renewable energy, UV radiation) or omitted (coastal mining, ocean acidification, plastic, light, noise pollution). We also consider the challenges and uncertainties inherent in predicting impacts of environmental changes by using hindsight to inform foresight.},

It has been hypothesized that ectomycorrhizal (EcM) in contrast to arbuscular mycorrhizal fungi can reduce tree species diversity in local communities, which remains to be tested at the global scale. To address this gap, we analyzed global forest inventory data and revealed that the relationship between tree species richness and EcM tree proportion varied along environmental gradients. Specifically, the relationship is more negative at low latitudes and in moist conditions but is unimodal at high latitudes and in arid conditions. The negative association of EcM tree proportion on species diversity at low latitudes and in humid conditions is likely due to more negative plant-soil microbial interactions in these regions. These findings extend our knowledge on the mechanisms shaping global patterns in plant species diversity from a belowground view.},

abstract = {Much emphasis has been placed on the negative consequences of alien species on resident ecosystems. Nevertheless, quantitative studies on the effects of invasive and native plant communities on soil nutrients and microbial features were rarely conducted. This study investigated soil microbes and soil nutrients associated with different degrees of Ageratina adenophora invasion and plant communities (Gramineae and Dicotyledons). The correlations between soil microbes and soil nutrients were analyzed. The findings indicated that the invasion of A. adenophora markedly elevated the levels of soil total nitrogen (TN), nitrate nitrogen (NO3--N), ammonium nitrogen (NH4+-N), available potassium (AK) and available phosphorus (AP), while decreasing the concentrations of soil total phosphorus (TP) and total potassium (TK) in comparison with those in non-invaded areas. The concentrations of NO3--N, NH4+-N, and AK in strongly invasive plant communities were significantly greater than those in the Gramineae and Dicotyledon groups. The soil microbial richness of the A. adenophora invasive plant community was higher than that of the native plant community. In contrast, the soil microbial evenness was lower than that of the native plant community, but the soil microbial dominance increased with the increasing degree of A. adenophora invasion. Meanwhile, the number of soil bacteria, fungi, actinomycetes, nitrogen-fixing bacteria, potassium-solubilizing bacteria and phosphate-solubilizing bacteria in the invasive plant community increased significantly with increasing degree of A. adenophora invasion. The soil microbial richness of the invasive plant community dominated by A. adenophora was higher than that of the native plant community. In contrast, soil microbial evenness was reduced in the invasive community compared to the native plant community, while microbial dominance increased with the extent of A. adenophora invasion. The number of bacteria, fungi, actinomycetes, nitrogen-fixing bacteria, potassium-solubilizing bacteria and phosphate-solubilizing bacteria in the soil of the invasive plant community increased significantly. Furthermore, the variation trend of the Simpson diversity index (D) was that of the Shannon diversity index (H) of the soil microbes in this study. The McIntosh diversity index (U) showed a consistent decrease with the increasing degree of A. adenophora invasion. Moreover, after the correlation coefficients between soil microbes and nutrients were analyzed, we found that there was a significant positive correlation between soil nutrients and microbial richness in both the A. adenophora invasive community and the native plant community. Compared with plant communities, A. adenophora invasion can greatly alter the soil nutrient and microbial characteristics and the trade-offs of soil nutrients supply and demand, which may facilitate growth. The soil microbial diversity in different communities may be important factors that led to changes of soil nutrients. A. adenophora altered the trade-offs of soil nutrients supply and demand by changing the composition and diversity of soil microbes, which may be a critical ecological mechanism of the successful invasion of the exotic weed A. adenophora successful invasion.},

Trees were protected from EAB colonization until 2012. We recorded current-year woodpecker holes and EAB adult exits on live trees annually from 2017 to 2022. Annual radial growth was quantified on increment cores from live trees and cross-sections from EAB-killed trees. Every Fraxinus nigra was killed by EAB by 2013. By August 2022, 63% of F. pennsylvanica, 12% of F. americana and 86% of F. chinensis trees had died. In contrast, F. quadrangulata trees were minimally colonized and remained healthy through 2022. Average (± SE) annual increment from 2007-2021 ranged from 2.65 ± 0.18 mm for F. quadrangulata to 4.61 ± 0.46 mm for F. chinensis. In an adjacent plantation planted in 2010, we assessed size, growth and EAB signs in 2022 on 12 live F. pennsylvanica and 12 Asian F. mandshurica. All F. mandshurica remained healthy with little evidence of EAB injury. Despite heavy EAB infestation, F. pennsylvanica radial growth in 2011 to 2022 remained relatively high. Results show F. nigra is highly preferred and vulnerable to EAB, followed by F. pennsylvanica, while F. americana is an intermediate host and F. quadrangulata is resistant. Of the 2 Asian species, F. mandshurica was resistant to EAB but F. chinensis trees were heavily colonized and most died.},

It can be informative for monitoring, but also for control programs where insects are mass-reared, and field-released. Here, we investigated how adult thermal acclimation in sterile Bactrocera dorsalis affects dispersal and recapture rates in the field using a mark-release-recapture method. We also considered how current abiotic factors may affect recapture rates and interact with thermal history. We found that acclimation at 20 or 30 °C for 4 d prior to release reduced the number of recaptures in comparison with the 25 °C control group, but with no differences between groups in the willingness to disperse upon release. However, the deleterious effects of acclimation were only detectable in the first week following release, whereafter only the recent abiotic conditions explained recapture rates. In addition, we found that recent field conditions contributed more than thermal history to explain patterns of recaptures. The two most important variables affecting the number of recaptures were the maximum temperature and the average relative humidity experienced in the 24 h preceding trapping. Our results add to the handful of studies that have considered the effect of thermal acclimation on insect field performance, but notably lend support to the deleterious acclimation hypothesis among the various hypotheses that have been proposed. Finally, this study shows that there are specific abiotic conditions (cold/hot and dry) in which recaptures will be reduced, which may therefore bias estimates of wild population size.},

abstract = {Understanding how the characteristics of native plant communities influence invasion is a pressing question, with implications for theory and management. For decades, the primary native community characteristic used in tests of biotic resistance was species richness. However, previous studies have demonstrated that evolutionary history and functional traits shape the invasion process, as ecological theory predicts. Theoretically, restoration projects would benefit from designing seed mixtures around maximizing resistance to invasion. However, there is little empirical evidence on the importance of evolutionary diversity for management and still less guidance for practitioners on effective application of ecological theories. We empirically tested how several native community characteristics (phylogenetic diversity, functional diversity, phylogenetic relatedness, and mean trait values) affected the survival of three introduced invasive species. We explored this question in experimentally restored 15-species prairie plots with three levels of phylogenetic diversity and two levels of functional diversity. Our experiment also included monocultures of all native species, which were also experimentally invaded. We found evidence that phylogenetic diversity conferred biotic resistance against one invasive species, contributing to reduced biomass in models explaining up to 10% of variance. Tall species better suppressed invaders, with height explaining up to 27% of variation in invader biomass. Surprisingly, we found patterns in leaf and seed traits linked to invasion resistance which were associated with both conservative and resource-acquisitive strategies. We also found evidence in both the diversity and monoculture plots that invaders were more successful with more closely related native species. Taken together, our results indicate that invasion resistance emerges from nuanced interactions between phylogenetic diversity, functional traits, and community composition, rather than from any single community characteristic. Our results underscore the complexity of biotic resistance and suggest that practitioners should prioritize phylogenetic diversity and strategic species selection when designing restoration plantings to enhance invasion resistance.},

We classify threat interactions into additive, synergistic and antagonistic according to the reduction of life history strategy and phylogenetic diversity. Most threat interactions are antagonistic; the effect of threats jointly is lower than the sum of the effects of threats separately. However, we find that the interaction between emerging diseases or invasive species with other threats has synergistic and additive effects, meaning that the combined effects are greater than or equal to the effects of threats separately. Our work can help target conservation strategies and detect key places to address multiple threats when they appear together.},

Life history traits, such as high growth and reproductive rates, and a high capacity to adapt to different environmental conditions may contribute to its invasive properties. Biotic stressors, such as herbivores, pathogens, and competing plant species are known to exert significant selective pressure on the plant's survival, distribution, and abundance. L. leucocephala has been reported to contain several compounds involved in the defense functions against these biotic stressors. A large amount of L-mimosine, a non-protein amino acid, was found in all plant parts of L. leucocephala, including its flowers. L-Mimosine is toxic to herbivorous mammals and insects, parasitic nematodes, pathogenic fungi, and neighboring competing plant species by inactivating various essential enzymes and blocking DNA replication, and/or inducing oxidative stress conditions. Several flavonoids, polyphenolic compounds, and/or derivatives of benzoic and cinnamic acids are toxic to parasitic nematodes, pathogenic fungi and bacteria, and competing plant species by disrupting plasma membrane structures and functions, and various metabolic processes. These compounds may represent the invasive traits of L. leucocephala that have undergone natural selection during the evolution of the species. They may contribute to the defense functions against the biotic stressors, and increase its survival, distribution, and abundance in the introduced ranges. This is the first review to focus on the compounds involved in the defense functions against biotic stressors.},

abstract = {Lolium perenne (Poaceae), a perennial forage, has high economic and nutritional value. It is often used as a replacement control for some invasive plants, as it has achieved good ecological and economic effects. However, its control effects, allelochemicals, allelopathic effects, release pathways, and contents are still unclear in the process of L. perenne replacement control of an invasive plant, Ageratina adenophora (Asteraceae). Therefore, it is necessary to reveal the mechanism of L. perenne replacement control of A. adenophora from the perspective of allelopathy. In this study, L. perenne could effectively inhibit the growth of A. adenophora in the competition assay. In addition, seven norsesquiterpenes (1-7) were isolated and identified from the whole plant of L. perenne, and most of the compounds exhibited potent allelopathic effects on the growth of A. adenophora and one model plant (Lactuca sativa, Asteraceae). Moreover, some active compounds were released into the environment through root secretion and rainwater leaching, and their contents were determined by UPLC-MS/MS (Ultra Performance Liquid Chromatography Tandem Mass Spectrometry). Our results elucidated the allelopathic mechanism of L. perenne's replacement control, A. adenophora, and provided a theoretical basis for the development of norsesquiterpenes from L. perenne.},

abstract = {Hakea decurrens subsp. physocarpa is an invasive species from Australia, with morphological, physiological and ecological features that help it colonize and settle outside of its natural habitats. One of these characteristics is allelopathy, which is an interaction that grants a clear competitive advantage to invasive species that has not been studied in H. decurrens subsp. physocarpa. With the aim of understanding the ecological relationships that take place in habitats invaded by this species, it is especially important to know the allelopathic potential of H. decurrens subsp. physocarpa and the compounds that would be involved in this interaction. To this end, the present study quantified the allelopathic activity of the aqueous extract of leaves gathered on four different occasions in the year, as well as of the compounds present in these extracts. The obtained results show a negative effect of H. decurrens subsp. physocarpa samples collected in March, June, September, and December on the germination and growth of Lactuca sativa. Although the negative effect was observed with all extracts, the extract of leaves gathered in September showing the greatest effect on germination (I50 = 0.08 g/mL), and that of leaves collected in June presented the greatest effect on root size (I50 = 0.05 g/mL). As for the composition of these extracts, nine compounds were identified and quantified through HPLC: arbutin, mesaconic acid, isotachioside, 1-O-vanilloyl-beta-D-glucose, syringic acid-4-beta-D-glucopyranoside, quercetin 3-robinobioside-7-glucoside, quercetin 3-rhamninoside, rutin, and isorhamnetin-3-O-rutinoside. There is a correlation between the quantified parameters and the quantity of these compounds in the extracts, but it is difficult to attribute the allelopathic activity of H. decurrens subsp. physocarpa to a particular compound, since this activity may depend on the combination of these compounds. In conclusion, this work demonstrates that the leaves of the invasive species H. decurrens subsp. physocarpa have allelopathic potential, and their toxicity could be due to the combined action of these compounds, which should be analyzed in future studies.},

This study introduces a gliding filamentous bacterium, the strain NSD29, isolated from natural forest soil in Xinjiang, China, as a biological control agent for managing this disease. Comprehensive characterization based on morphological, physiological, biochemical, 16S rRNA gene, and whole-genome analyses identified the strain NSD29 as Herpetosiphon llansteffanensis. The train NSD29 demonstrated potent predatory activity against E. amylovora in vitro. Its biocontrol efficacy was subsequently evaluated on detached leaves, inflorescences, young fruit, and shoots of fragrant pear under controlled greenhouse conditions. Results indicated that applying H. llansteffanensis NSD29 significantly inhibited lesion expansion on pear leaves and young fruit, achieving protective efficacies of 75.2% and 72.0%, respectively. Furthermore, pre-treatment spraying with NSD29 effectively reduced the incidence of blossom blight, with a control efficacy of 61.2%. On detached pear shoots, the application of NSD29 fermentation broth suppressed lesion expansion, demonstrating substantial protective (86.8%) and curative (75.6%) efficacies. This research provides the first evidence for the potential of Herpetosiphon species in the biological control of plant diseases, highlighting H. llansteffanensis NSD29 as a promising candidate for developing strategies to combat fire blight.},

Potentilla indica), a clonal invasive plant native to Asia, has rapidly spread in Europe, where its ecological adaptation allows it to thrive under varying environmental conditions. It is mostly found in urban habitats such as lawns, parks, and urban and peri-urban forests, where it thrives in various plant communities. It can become dominant in certain communities, indicating its competitive advantage over native plants. Due to similar habitat preferences, it often coexists with the native species Glechoma hederacea, with which it shares other characteristics such as clonal growth. This study investigates the effects of light, nutrients, and competition on the growth, morphology, and physiology of D. indica. A controlled pot experiment exposed plants to combinations of sunlight and shade, optimal and increased nutrient levels, and competitive scenarios with the native plant G. hederacea. The plant traits of biomass, leaf and ramet number, stolon and flower production, leaf greenness, the photosynthetic efficiency of Photosystem II, and stomatal conductance were assessed. Results revealed that light and nutrient availability significantly enhanced growth metrics. In shaded conditions, D. indica adapted with elongated petioles and increased specific leaf area. Competition significantly reduced growth, with G. hederacea outperforming D. indica. These findings highlight the complex interplay between abiotic and biotic factors in influencing invasive species impact, providing essential insights for ecosystem management.},

abstract = {The proliferation of invasive alien plants (IAPs), coupled with the decline in native biodiversity, poses a significant threat to global ecological stability. These processes disrupt native plant communities and trigger cascading effects on vital soil functions, such as carbon cycling. While IAPs are known to alter soil properties, the mechanisms driving these changes, particularly in the context of simultaneous biodiversity loss, remain poorly understood. This pot-based study simulated the reduction in native plant biodiversity caused by Solidago canadensis L. invasion, a highly aggressive IAP, to explore its impact on soil microbial resource acquisition strategies and carbon use efficiency (CUE). Four treatments were established: early invasion with high native plant diversity, moderate invasion with moderate diversity, high invasion with low diversity, and complete invasion with no native diversity. The soil microbial nutrient acquisition strategies and CUE were analyzed using eco-enzymatic stoichiometry within the frameworks of ecological stoichiometry and metabolic ecology theories. Our results revealed a significant depletion of inorganic nitrogen and dissolved organic nitrogen in high invasion with low diversity treatment soils (p < 0.05), leading to nitrogen limitation. Microbial nutrient acquisition strategies shifted toward nitrogen prioritization with increasing S. canadensis invasion, reflected by reduced eco-enzymatic carbon-to-nitrogen stoichiometry. CUE increased significantly along the S. canadensis invasion gradient, rising by 55.7%-63.5% (p < 0.05), driven by shifts in microbial nutrient acquisition strategies. These findings demonstrate that S. canadensis invasion-induced biodiversity loss disrupts nutrient dynamics and enhances CUE, potentially accelerating soil fertility degradation and ecosystem instability.},

The objective of this study was to characterize the feeding, growth and abundance of S. glanis in 12 lakes and 12 rivers within its European native range in relation to environmental changes that may explain population trends over time. The results suggest a shift in factors limiting the carrying capacity of catfish habitats within this range, leading to increases in growth and abundance. Statistical modelling identified warming and increasing population density of invasive gobies as likely contributors to this shift. Given that catfish predation on native species can be expected to increase dramatically, there is an urgent need for new management strategies. It is recommended that catfish removal rates should be increased, especially in areas of high importance for native fish and crayfish species, such as spawning grounds and at bottlenecks for migration.},

abstract = {Many invasive species are capable of rapidly advancing invasion forefronts, often into areas with challenging or extreme environmental conditions. Understanding the mechanisms driving these invasions is essential for predicting their future spread and developing effective conservation strategies. A notable example is the recent range expansion of the golden mussel (Limnoperna fortunei) from low- to high-latitude regions, which poses significant threats to the integrity of global freshwater ecosystems and socio-economic sustainability. Successful invaders often utilize a variety of physiological, behavioural and ecological strategies to survive and thrive in harsh environments. To investigate the multi-dimensional mechanisms underlying low-temperature tolerance for high-latitude invasion success, we collected golden mussels from their northernmost invasive range. The mussels were exposed to a control temperature of 25°C and low temperatures of 15°C and 5°C. We conducted multi-level analyses, including behavioural (survival and valve activity), morphological (filament ultrastructure), biochemical (enzyme content) and molecular (transcriptome and metabolome) changes in the gill, a key organ involved in low-temperature response. We observed low mortality rates (<30%) across all stressed groups, indicating the golden mussel's tolerance to low temperatures. Upon initial exposure, the golden mussels significantly reduced their valve-opening rate, effectively blocking cold water outside their bodies. Microscopic observations and staining analyses revealed significant changes in the gill filaments, including alterations in cilia, filament cells and junction distances, suggesting functional morphological adjustments following the behavioural response of valve closure. The energy conserved through these morphological changes, along with actively generated energy, was utilized to enhance tolerance at the biochemical and molecular levels. This energy-intensive tolerance mechanism involved apoptosis inhibition, membrane fluidity enhancement, improved antioxidant capacity and elevated immune regulation, as evidenced by enzyme assays and integrated transcriptomic and metabolomic analyses. These adjustments interacted and coordinated, demonstrating highly systematic and complementary responses to the low temperature stress. Our study elucidates the multi-dimensional mechanisms employed by golden mussels to cope with extreme temperature conditions in high-latitude regions, highlighting the integrated strategies that facilitate their survival in harsh environments. These findings offer valuable insights for developing management strategies for regions characterized by extreme environmental conditions for invasive species.},

Here, we examined the ecological and evolutionary consequences of flower color polymorphism in Roscoea cautleoides, an alpine ginger with sympatric distribution of purple- and yellow-flowered plants. Variations in pollinator visitation and specialization to the flower color contributed greatly to pre-zygotic reproductive isolation, with post-zygotic isolation also observed in reciprocal pollination. Yellow-flowered plants evolved independently from purple-flowered plants in two populations due to the absence of anthocyanins, as supported by metabolic, expression, and genetic analysis. Despite early genetic divergence between the two-flower-colored plants, highly differentiated genes were associated with reproduction and stress, while highly selective genes were enriched in stress. Our results suggest that parallel loss of anthocyanins leads to flower color polymorphism in different populations of R. cautleoides, with pollinator preference contributing to reproductive isolation and subsequent genetic differentiation, indicating the process of incipient speciation triggered by flower color changes with sympatric distribution.},

abstract = {Mugger crocodiles are the apex predator species of the wetland ecosystem in Nepal, and their conservation could safeguard the entire ecosystem. However, studies on their population status and habitat characteristics are limited, with no scientific research conducted on their nesting ecology to date. Therefore, we selected muggers as a representative species to better understand their daytime sightings, nesting characteristics, and the fine-scale anthropogenic and environmental factors influencing their occurrence in five lakes of the Beeshazari Lake complex (BLC; Beeshazar Lake, Kumal Lake, Tikauli Lake, Kingfisher Lake, and Batuli Pokhari) of Chitwan National Park, Nepal. We conducted a preliminary survey, followed by a daytime sightings survey, a nesting site survey, and a habitat assessment survey in March 2023. A generalised linear model under binary logistic regression was used to analyse the factors influencing the habitat characteristics of muggers. During the research period, 50 detections of muggers were recorded, 66% of which were observed basking and 34% were submerged in the lakes. The Relative Abundance Index of the muggers in the BLC was 3.29 km[-1]. Nesting sites (two from Tikauli Lake and three from Beeshazar Lake) were recorded during the study period. The probability of sighting a mugger was significantly influenced by the slope (moderate slope), substrate type (clay, grass, and sand), mid-lake depth, presence of anthropogenic threats, and presence of invasive species. We recommend that future researchers employ more robust models, such as N-mixture models, to provide up-to-date information on the population abundance of muggers in the BLC. Furthermore, a comprehensive multi-seasonal study focusing on ecological and behavioural aspects of nesting sites alongside environmental aspects influencing nest success rates is critical. Such research will be crucial in guiding the development of targeted conservation strategies aimed at protecting and preserving essential nesting sites. Moreover, we recommend conducting robust studies on the carrying capacity of wetlands in Nepal to provide insights into the sustainable population size that a wetland can support.},

Nutrient enrichment increased total biomass more in native plants than in invasive plants. ALAN enhanced total biomass in both groups of plants without herbivory, but increased native plant biomass and decreased that of invasive plants under herbivory. ALAN reduced root mass fraction, especially under low-nutrient conditions without herbivory. Native plants exhibited greater tolerance to herbivory and higher net photosynthetic rates under ALAN compared to invasive species. Moreover, S. litura larvae grew faster on invasive plants but slower on native plants under ALAN. These findings suggest that ALAN may weaken the competitive advantage of invasive species by enhancing the defence mechanisms and physiological performance of native plants, potentially shifting competitive dynamics in favour of native flora.},

With the refinement of molecular methods, microbiome research has extended to other key marine organisms such as macroalgae. The microbiome plays a key role in macroalgal health, adaptation to environmental conditions, and resilience to climate stressors. The main factors affecting the algal microbiome are host specificity (genetics, functional profile, phylum and species identity), life stage, morphology, thallus region, and tissue age. Other significant drivers of microbiome community structure include spatiotemporal distribution and environmental conditions, especially as global stressors intensify with climate change. The mechanisms through which the microbiome of invasive seaweeds might enhance their competitiveness over native species are still unclear. However, there is evidence that, like climate resilience, invasive potential is linked to the functional flexibility of associated microbiota, allowing the host to adapt to the new environmental conditions. The main objective of this review was to synthesize the current understanding of the macroalgal microbiome and propose future directions in microbiome research based on identified shortcomings. Based on the knowledge gaps detected, there is an urgent need for multi-factorial experimental studies that link host and microbiome gene expression through chemical signals under future climate change scenarios, standardization of analytical methods, and a focus on underrepresented geographical regions and species. While algal microbiome research holds great promise for predicting and mitigating the effects of climate change and invasive species, embracing new tools and tackling ecologically relevant mechanistic and applied questions will be essential to advancing this field.},

Halyomorpha halys is an invasive agricultural pest characterised by a unique overwintering strategy where individuals aggregate and enter a state of dormancy, making it an excellent model to study the relationship between microbiota and diapause. We investigated the bacterial diversity of wild H. halys specimens before and after dormancy using 16S rRNA gene amplicon-sequencing. We found that microbiota varies between geographically neighbouring sampling locations, but there were no significant differences in microbial diversity or composition between populations sampled before and after diapause, despite stressful overwintering conditions. Such stability may relate to the highly specific taxa that dominate the stinkbug-associated microbial community. In addition, we did not detect any strong association of stink bugs with phytopathogens, but we found that two populations harboured Nosema maddoxi, a microsporidian pathogen of stink bugs. Our results are relevant to the assessment of accidental spillovers of microorganisms in newly invaded areas and to the implementation of the sterile insect technique based on mass trapping, irradiation, shipping and release after diapause of wild individuals.},

Using threat probability maps based on the International Union for Conservation of Nature Red List and the World Database of Protected Areas, we analyzed the relationship between PA coverage and the major threats to amphibians, birds, mammals, and reptiles-agriculture, hunting, logging, pollution, invasive species, and urbanization. We included data on 33,379 species and 255,848 protected sites. We analyzed the relationship between threat probabilities and PA coverage with generalized additive models. Then, we grouped grid cells into discrete threat-protection categories and examined global spatial patterns. We focused three types of areas: areas with a high probability of threat that coincided with inadequate PA coverage; areas that had simultaneous threats; and areas with a high concentration of threatened species. We found a potential disconnect between global PAs and threat coverage. Twenty-one percent of areas had a high probability of threat, of which 76% were insufficiently protected. Over half of amphibian and mammal habitat was highly threatened and was insufficiently covered by PAs. Amphibians were subject to the highest proportion of simultaneous threats. Underprotected areas harbored the largest proportion of threatened species across all taxonomic groups. Our results provide crucial insights into the spatial relationship between threats and PA coverage and can be used to inform conservation planning at large scales.},

When control measures are initially effective, they may drive evolutionary adaptation that prevents full eradication, as has been documented for some chemical and biocontrol approaches. Although the intensity, directionality, and persistence of selection required to increase the frequency of resistant genotypes in complex natural ecosystems remains an open question, theory predicts that high mortality can cause life-history evolution even in the absence of a strong selective agent. Here, we use annually collected ecological and genetic data to show that rapid evolution of introduced smallmouth bass has undermined a 20-y manual suppression effort in a mid-sized lake. Despite nearly doubling annual mortality, our intensive control program produced a larger bass population dominated by young and early-maturing fish. These shifts were accompanied by large allele frequency changes in three genomic regions associated with earlier maturation and increased somatic growth. Our findings bear out the theoretical prediction that high mortality can drive evolutionary adaptation in target species. Controlling species invasions are worldwide practices that typically remove a substantial proportion of a population during each of many successive generations, hence life history adaptation may be commonplace. Such evolutionary responses could be salient in explaining the widespread failure of invasion control efforts. Genetic and phenotypic monitoring to detect cryptic adaptation and preemptive design of invader eradication programs to deliberately disrupt directional selection for resistance could improve invasion control outcomes.},

abstract = {Larvicides are widely used for mosquito control, but resistance development complicates efforts. We investigated the interplay between insecticide resistance and environmental stress in Aedes albopictus, Culex pipiens pipiens, and Culex pipiens molestus. Mosquitoes were selected for resistance to diflubenzuron and Bacillus thuringiensis subsp. israelensis, acclimated at four temperatures, and subjected to desiccation and starvation assays. Desiccation and starvation survival were affected by species, sex, and thermal acclimation, but not by larvicide resistance. Larvicide resistance affected starvation survival in Ae. albopictus, which also exhibited higher thermal plasticity under both stressors. Females outlived males across all species and conditions. These findings highlight ecological consequences of larvicide resistance, as it does not compromise stress resistance and thermal plasticity, complicating mosquito control amid climate change. Trade-offs between starvation and desiccation in Ae. albopictus suggests potential mechanistic links between these traits and larvicide mode-of-action. Species-, context- and trait-specific larvicide resistance responses complicates mosquito control efforts.},

abstract = {Local adaptation is common in invasive plants, but there is no consensus as to whether shifts in functional traits between invader "home" and "away" ranges contribute to their success in competition with native species. Theory based on enemy release suggests that invaders should reallocate limiting resources away from nutritive-based defenses and toward high growth potential. However, empirical studies of home-away trait shifts are typically conducted on a single invader and fail to consider how environmental differences across regions may impact leaf trait syndromes. We measured nine defense-related leaf traits for 27 invasive species across their home and away ranges in France, Japan, and the United States, and compared them to distributions of those same traits for co-occurring native species in both their home and away ranges. Our study included a total of 21 woody species sampled under forest canopies, and 23 herbaceous species sampled in fields and roadsides. Traits included toxic leaf alkaloids and cyanogenic glycosides; structural attributes including cell wall mass and fiber content; carbon (C), nitrogen (N), C:N, and total protein content; and specific leaf area. We found significant overall shifts in both qualitative (alkaloids) and quantitative (fiber, cell wall, N content) defense traits, particularly in woody species that are hypothesized to be more apparent to herbivores. However, the direction of trait shifts was not consistent across regions. Rather, for seven of nine traits, trait means of invaders shifted toward the means of native species in the recipient communities, likely reflecting environmental differences among regions rather than a shift in allocation from defense to growth. We suggest this "join the locals" pattern, whereby trait shifts in invaders match regional differences in native trait syndromes due to environmental variation, is a reasonable null model for studies of adaptive evolution in invasive species. Although the "join the locals" pattern is not mutually exclusive with shifts in functional traits caused by enemy release, our study involving multiple species and habitats suggests environmental gradients override trait shifts driven by varying herbivore communities.},

Increasing demands on water infrastructure coupled with climate change mean that the reliance of the water industry on RWT will increase significantly within the next decade. RWTs are recognised as a high-risk pathway for the spread of freshwater invasive non-native species (INNS), however the movement of invasive micro-organisms via RWT is yet to be explored. This study aims to qualitatively assess the risk of transfer and establishment of invasive pathogens as a result of RWTs. Using the Source-Pathway-Receptor-Consequence model, the pathways and processes involved in micro-organism movement due to RWT are mapped, and high and low risk scenarios with respect to pathogen spread via RWT are presented. The biological factors affecting the survival and persistence of pathogens are discussed, and how these interact with the physical parameters of RWT. We have highlighted potential freshwater diseases of importance to the UK and demonstrated their potential for transmission via RWT due to their to persistence within the environment. This risk analysis provides evidence that a more detailed study of pathogen interactions with RWT variables is required to enable quantitative risk assessments to be made, in anticipation of future legislative policy.},

abstract = {BACKGROUND: The black bean bug Brachyplatys subaeneus is a crucial legume crop pest native to Asia. It has been introduced to the Americas and rapidly in tropical and subtropical regions, where it poses a serious threat to local legume crops. However, the native population structure and invasive sources of this pest have never been studied, hindering effective monitoring and management. Here, we investigated the genetic structure of native populations based on nuclear SNP data and genetic relationship between the Panama samples and the native samples based on COI and 16S rRNA sequences. In addition, we constructed ecological niche models to predict its potential invasion areas.

RESULTS: We found that B. subaeneus comprised three geographic lineages (NO, PH and SO) within its native range, with strong genetic differentiation between these lineages. Genetic relationships based on mitochondrial DNA between the native and invasive samples indicated that Panama samples used in this study were derived from NO lineage. Ecological niche modelling shows a wide range of suitable habitats in the northern and central regions of South America, suggesting that B. subaeneus has the potential to expand further south from the northern regions of South America.

CONCLUSION: This study revealed the genetic structure of B. subaeneus in its native range, inferred the possible geographical origin of invasive populations, and indicated the potential invasion areas for the bean bug. Our findings in this study could provide new insights into the monitoring and management efforts of this invasive pest. © 2025 Society of Chemical Industry.},

abstract = {BACKGROUND: Bursaphelenchus xylophilus, the pathogen responsible for pine wilt disease, significantly threatens pine forests globally, with rapid infection leading to tree mortality within 40 days. This disease spreads efficiently through vector beetles, with Monochamus alternatus and Monochamus saltuarius serving as the primary vectors and Monochamus galloprovincialis being considered a potential vector in China. Molecular traceability and stable isotope traceability are both important techniques for insect tracing, each with its own advantages and limitations. Molecular traceability, such as DNA-based methods, offers high specificity and accuracy in identifying insect species, but it may require more complex procedures and higher costs due to the need for advanced equipment and skilled personnel. Stable isotope tracing, however, provides conservative and high-precision signatures, and is label-free, making it suitable for tracing the origins and pathways of insects in complex environments. Using the method of degreasing, the fat of the sample epidermis was removed, only the bone part was left, and the abdominal cavity was emptied to prevent the food from affecting the determination of hydrogen isotope. The present study aimed to trace the geographic origins of these vector insects in China using hydrogen stable isotope ratios, providing a novel tool for disease management.

RESULTS: Data processing and modeling were conducted using R and Origin software, yielding the equation y = 0.9822x + 19.1765. Statistical tests confirmed the model's significance and fit. Results indicate a significant positive correlation of temperature and precipitation with atmospheric hydrogen isotopic composition.

CONCLUSION: Our findings demonstrate the model's applicability in tracking the spread of pine wilt vectors, offering a promising approach to forest pathogen management. If the sample isotope test value is brought into the model and marked in the partition diagram, it can be proved that the model can effectively identify the source information of the sample. © 2025 Society of Chemical Industry.},

abstract = {BACKGROUND: Forests in nearly all regions worldwide are affected by invasions of non-native bark beetles. Hylurgus ligniperda (Fabricius) is a globally invasive bark beetle that stealthily jeopardizes pine health and spreads worldwide insidiously. The worldwide occurrence of Hylurgus ligniperda challenges trade in pine logs or wooden materials. Early identification of Hylurgus ligniperda is crucial in implementing appropriate pest management strategies.

RESULTS: This study established a simple, efficient, and accurate method for identifying Hylurgus ligniperda based on recombinase polymerase amplification and the lateral flow dipstick (RPA-LFD). The method can distinguish Hylurgus ligniperda from other species and has a sensitivity threshold of 10 fg/μL. Subsequently, field application tests were conducted using RPA-LFD assays, the first field application case in forestry entomology. The field test results showed that RPA-LFD combined with crude DNA extraction could accurately identify Hylurgus ligniperda (except elytra). The influence of environmental factors (temperature, humidity, and wind) was also investigated. The results showed that only wind speed (P = 0.003) was significantly correlated with the color rendering of the LFD and negatively correlated with the color and density of the LFD detection line.

CONCLUSION: A rapid field-based identification method applied helps the elimination of barriers to the lagging identification of invasive pests. Implementing RPA-LFD aims to provide a reliable and efficient tool for rapidly identifying invasive insects, enabling timely intervention and effective management strategies. © 2025 Society of Chemical Industry.},

abstract = {BACKGROUND: The efficacy of integrated pest management programs can be affected by interactions between different pest control methods. Silicon (Si) amendments increase plant resistance to phytophagous insects; however, such amendments may also affect higher-trophic level species, causing either negative or positive impacts on the biological control of pests in treated crops. To evaluate the effect of Si amendment on the potential for control of the pest aphid Melanaphis sorghi (Theobald) by the parasitoid Aphidius platensis (Bréthes), the key biological parameters and the fertility life tables of both species were assessed in the laboratory at both 23 ± 1 °C and 29 ± 1 °C without Si application and in a greenhouse trial, with the insects reared on plants grown in soil with and without the application of Si (800 kg of Si per hectare).

RESULTS: Without Si, the net reproductive rate (R0) value of the parasitoid at 23 °C was higher than that of the aphid (ratio of R0 of parasitoid/R0 of aphid = 1.2), showing that the aphid can be controlled by the parasitoid at this temperature, but at 29 °C this reversed, with the R0 ratio declining to 0.79, permitting aphid outbreaks. In contrast, with Si, the parasitoid's R0 and rm (intrinsic rate of increase) were both equal or higher than the aphid's at both temperatures, with parasitoid/aphid ratios for R0 and rm ranging from 1.0 to 1.8.

CONCLUSION: Silicon amendment can increase A. platensis control of M. sorghi, representing its potential use in the integrated management of this pest in sorghum. © 2025 Society of Chemical Industry.},

abstract = {BACKGROUND: While natural forests have decreased globally, forest plantations have expanded highlighting the need for studies on plantations' capacity to sustain biodiversity and provide ecosystem services within agroforestry mosaics. This study examined the breeding habitat preferences of European honey buzzards Pernis apivorus (a native predator of the invasive yellow-legged hornet) and their relationship with reproductive performance in exotic Eucalyptus plantations in southwestern Europe. We expected better reproductive performance in preferred habitats.

RESULTS: Breeding habitats (n = 57 nesting locations) and randomly selected control points (n = 77) were compared across spatial scales. We analyzed the relative importance of vegetation and topographic features, intraspecific territorial behavior, and interspecific interactions within the diurnal raptor guild. Two complementary approaches were employed: binomial generalized linear models for predictive habitat models, and random forest classification models to assess the relative importance of habitat factors. We examined the relationship between habitat preferences and reproductive performance based on laying phenology and fledgling success. Vegetation and topography were the most influential factors affecting habitat preferences, especially around nests (a 200 m-radius circle). Honey-buzzards preferred large nest trees within forest patches exhibiting high structural complexity and maturity. Preferred habitats were negatively associated with fledgling success, and no significant relationship was detected with laying phenology.

CONCLUSIONS: Our results suggest that Eucalyptus plantations can offer suitable breeding habitats for honey-buzzards if managed appropriately. This finding is crucial for guiding forest management decisions aimed at enhancing high-quality breeding habitats for honey-buzzards and encouraging their regulatory services against yellow-legged hornets. © 2025 The Author(s).

These challenges underline the need for control measures, though public perception can affect efforts. This study explores attitudes toward monk parakeet management among residents from Santiago, Chile. Five-hundred and four online surveys were applied and distributed through online social networks aimed at inhabitants in the Metropolitan Region. Although most citizens recognize that the parakeets can produce environmental impact, respondents do not consider them as a threat to health or the economy. Seventy percent of participants believe there should be a population control program for monk parakeets in place, and the control method is not significantly related to people's support. Sixty percent of respondents support parakeet eradication if they cause damage to native species or if they transmit pathogens to humans or other animals. However, this acceptability decreased considerably if eradication is conducted due to economic damages. Our results demonstrate that, despite a high level of appreciation to parakeets, there is a general willingness to support its management, including eradication, in pursuit of biodiversity conservation and public health. However, citizens need information to know the threats of this invasive bird, given that management initiatives will receive greater support when society understands the potential parakeet impact on environmental, health, or economic realms and when specific and compelling methods are used. It is important for decision-makers to acknowledge beliefs and concerns that could hinder the management of monk parakeets in order to prevent social conflicts.},

However, we frequently lack data to gauge both negative impacts of non-native species and success or failure of chosen management interventions to benefit native species. Addressing these knowledge gaps is critical to improving management outcomes for native species while maintaining public trust to sustain funding of management activities. Here, we investigated the response of Lythrum salicaria (purple loosestrife) and associated plant communities to implementation of biological control in more than 10 wetland sites in New York State for up to 28 years. Introduced to North America from Europe in the 1800s, L. salicaria is a prime example of a non-native species with a continent-wide distribution that could not be suppressed by mechanical and chemical treatments. In the 1980s, waterfowl biologists, wetland managers, and conservationists alike worried about the loss of diverse wetland plant communities associated with the rapid expansion of L. salicaria. In response, after careful assessments of safety, and potential costs and benefits, four highly host-specific insect herbivores were released in North America in the early 1990s to reduce L. salicaria abundance and its negative ecological impacts. In a companion paper, Blossey et al. documented reduced L. salicaria occupancy and stem densities following insect releases over time (i.e., biological success), irrespective of site-specific differences in starting plant communities or L. salicaria abundance. Here, we show that reduced abundance of L. salicaria leads to the ultimate goal of non-native plant management: increased cover, abundance, and diversity of species, often of native species (i.e., ecological success). We also conduct analyses to provide inference about which plant species are most sensitive to L. salicaria, including changes in L. salicaria stem density. Overall, we provide an important conservation success story: our findings emphasize that biocontrol of non-native plants can be effective and safe, allowing native species to recover as a dominant non-native species gradually declines.},

Genetic analyses revealed three distinct genetic compositions with different levels of genetic diversity, suggesting multiple introductions into the country. The genetic composition of mosquitoes in most counties resembled southern Ethiopian populations, while those from Turkana showed a unique haplotype. A species distribution model predicts a more extensive range than currently observed, with low precipitation and minimal seasonal temperature variations as key factors influencing distribution. Challenges in adult sampling were noted, with larval sampling revealing co-occurrence with native Anopheles species. The findings have implications for surveillance and control strategies, emphasizing the need for continued monitoring, refined sampling techniques to inform bionomics, and cross-border collaboration.},

To address this problem, we investigated the role genome structural variants (SVs) play in adaptations of Anopheles stephensi, a primary vector of urban malaria in South Asia and an invasive malaria vector in South Asian islands and Africa. Using whole genome sequencing data we identified 2,988 duplications and 16,038 deletions SVs in 115 mosquitoes from invasive island populations and four locations from mainland India, the species' ancestral range. The minor allele frequency of SVs and amino acid polymorphism suggests SVs are more deleterious than the amino acid variants. However, high-frequency SVs are enriched in genomic regions with signatures of selective sweeps, implying a putative adaptive role of some SVs. We revealed three novel candidate duplication mutations for recurrent evolution of resistance to diverse insecticides in An. stephensi populations. These mutations exhibit distinct population genetic signatures of recent adaptive evolution, suggesting different mechanisms of rapid adaptations involving hard and soft sweeps helping the species thwart chemical control strategies. We also identify candidate SVs for the larval tolerance to brackish water, which is likely an adaptation in island and coastal populations. Nearly all high-frequency SVs and the candidate adaptive variants in the island populations are derived from the mainland, suggesting a sizable contribution of existing variation to the success of the island populations. Our results highlight the important role of SVs in the evolutionary success of invasive malaria vector An. stephensi.},

We review past mathematical models of wilding pine spread, including spatially explicit individual-based models, recursive partitioning methods, and integrodifference matrix models (IDMs). In contrast to these approaches, we use partial differential equations to model an invasion. We show that invasions are almost static for a significant period of time before rapidly accelerating to spread at a constant rate, matching observed behaviour in at least some field sites. Our work suggests that prior methods for estimating invasion speeds may not accurately predict spread and are sensitive to assumptions about the distribution of parameters. However, we present alternative estimation methods and suggest directions for further research.},

abstract = {From August to October 2024, 62 specimens of the non-native mosquito species Anopheles hyrcanus were trapped in the federal state of Brandenburg, northeastern Germany. At one site, 59 specimens, and at a second site, 3 specimens were collected, with both sites located in floodplain areas, approximately 25 km apart. The records represent the northernmost collection sites of this species worldwide. Anopheles hyrcanus is considered a potential vector of malaria parasites, dirofilarial worms, and various viruses, although vector capacity appears to be generally low. The findings in Germany follow the recent detections of the species in Hungary, Slovakia, Czechia, Austria, and Poland, suggesting possible establishment in more northern areas as a consequence of climate change.},

abstract = {Invasive non-native fish species can profoundly disrupt ecosystems. In invasion ecology, using the functional similarity with native species to help predict demographic rates of non-native species and infer the ecological processes underlying it remains largely unexplored. Utilizing a comprehensive analysis of 2,903 species pairs across 153 sampling sites in rivers distributed in different continents, we evaluated interspecific synchrony patterns among populations of native and non-native fish species and explored their relationship with functional and phylogenetic dissimilarities using a linear mixed model. Our results indicate that non-native fish exhibit higher synchrony with native species that share similar ecological and morphological traits. This finding corroborates our hypothesis that co-occurring non-native and native species that are more functionally similar are more synchronized and emphasizes the importance of environmental filtering significantly shaping population dynamics between native communities and coexisting non-native species. We highlight the potential of widespread non-native species in increasing synchronous patterns and consequently decreasing community stability. By elucidating which type of dissimilarities (ecological, life history, morphological, and phylogenetic) can predict synchrony and which ecological mechanisms facilitate the coexistence of native and non-native species, this research underscores the ecological implications of invasion dynamics in the long term and helps to guide conservation efforts.},

The connection of watersheds throughout Europe by the construction of artificial shipping canals has created novel invasion pathways, but may also provide critical infrastructure to counter range expansion by implementation of different barrier solutions. Here, we critically review the efficacy, applicability and limitations of dispersal barriers against AIS in shipping canals considering fishes, invertebrates, algae, bacteria and fungi. Despite the wide spread of AIS and their known detrimental effects on aquatic ecosystems, research focusing on barriers for AIS in shipping canals is rather limited and predominantly concentrated on a few species of fish. Out of 180 screened studies, only 32 examined the efficacy of technologies such as electric fields, acoustic signals, strobe light, air-bubble curtains, CO2 and pheromones as non-physical barriers. Efficacy and applicability was mostly tested in laboratory setups and strongly species-dependent, requiring a site-specific identification of the most useful barrier technology. Major limitations to barrier implementation include undesired and unknown side effects on non-target species, humans and the environment. To preserve the ecological integrity of freshwater ecosystems across transboundary and inland watersheds, future research should tackle these challenges by increasing the number of studies under realistic field conditions to allow evidence-based decision making on the management of AIS.},

abstract = {The spread of invasive species in marine ecosystems is a growing global concern, particularly in regions with high economic and ecological importance. Sun corals (Tubastraea spp.) are native scleractinians from the Pacific Ocean that have spread along most of the Brazilian coast. This invasive species initially established populations in Rio de Janeiro state, SE Brazil, reaching high levels of abundance. Although the ecological aspects and impacts caused by this organism have been studied in detail, the natural mechanisms that drive its dispersal have attracted little attention. In this research, we focus on the coastal dispersion of sun coral larvae between Cabo de São Tomé and Ilha Grande Bay, and the offshore transport of sun coral larvae, investigating how submesoscale oceanographic features such as filaments, fronts and eddies influence connectivity among different sites. A high-resolution numerical model was used to simulate the coastal dynamics, incorporating the influence of the Brazil Current, wind-driven circulation, and submesoscale structures. Larval dispersal was examined under different wind scenarios, including northeasterly winds that drive southward currents and enhance offshore transport via submesoscale filaments. Results show that submesoscale features, particularly filaments emerged from upwelling regions, play a significant role on sun coral larvae dispersion. These features act as pathways that connect larvae from coastal to offshore oil exploration areas, highlighting the importance of both natural and anthropogenic processes for the dispersal of this invasive species. This research provides critical insights into the mechanisms governing the spread of invasive marine species, emphasizing the need for integrated coastal management strategies. Understanding how physical processes drive larval transport is essential for developing targeted control measures to mitigate the impact of invasive species like sun coral on native ecosystems and local economies. Furthermore, the study underscores the importance of monitoring both natural and anthropogenic influences on marine bioinvasions, particularly in regions with significant offshore industrial activities.},

Bark beetles are known for extensive damage to forests globally, as well as for uniform and homoplastic morphology which poses identification challenges. Utilizing a MaxViT-based deep learning backbone which utilizes local and global attention to classify bark beetles down to the genus level from images containing multiple beetles. The methodology involves a process of image collection, preparation, and model training, leveraging pre-classified beetle species to ensure accuracy and reliability. The model's F1 score estimates of 0.99 and 1.0 indicates a strong ability to accurately classify genera in the collected data, including those previously unknown to the model. This makes it a valuable first step towards building a tool for applications in forest management and ecological research. While the current model distinguishes among 12 genera, further refinement and additional data will be necessary to achieve reliable species-level identification, which is particularly important for detecting new invasive species. Despite the controlled conditions of image collection and potential challenges in real-world application, this study provides the first model capable of identifying the bark beetle genera, and by far the largest training set of images for any comparable insect group. We also designed a function that reports if a species appears to be unknown. Further research is suggested to enhance the model's generalization capabilities and scalability, emphasizing the integration of advanced machine learning techniques for improved species classification and the detection of invasive or undescribed species.},

abstract = {Anthropogenic degradation of wetlands often leads to regional biotic homogenization and reduced plant diversity. This reduction is often attributed to the proliferation and dominance of a few generalist, often non-native, species. Biotic resistance from natives can sometimes impede the growth and spread of colonizers, but its dependence on environmental conditions is poorly understood. Based on field and modeling studies, we tested the predictions that (1) biotic resistance declines at higher nitrogen loading and (2) size influences colonization success. In a five-growing season mesocosm experiment, we grew three cattail taxa: Typha latifolia (native, large), Typha angustifolia (non-native, invasive, smallest), and Typha × glauca (hybrid, most invasive, large) as potential colonizers in the presence or absence of pre-established resident vegetation. At two sites differing in climate and growing season length, biotic resistance treatments were crossed with 12 nitrogen levels (inflows 0-45 g N m[-2] year[-1]). Each treatment combination was replicated twice, totaling 48 mesocosms per site. Without residents, colonizers (as total biomass of all three cattail taxa) persisted and expanded clonally across all nitrogen levels. However, their expansion was generally lower when colonizing a pre-established resident community compare to bare ground. The magnitude of biotic resistance, measured as the effect of residents on colonizers' biomass, and its interaction with nitrogen differed between sites. As predicted, biotic resistance decreased with high nitrogen at the northern site, but at the southern site, residents nearly eliminated colonizers. As anticipated, smaller T. angustifolia was a poorer colonizer than the other taxa, while T. × glauca was the strongest colonizer, especially under high nitrogen conditions where biotic resistance was minimal. Our findings partially support the hypothesis that biotic resistance declines with nitrogen loading, indicating that additional research on the factors influencing the magnitude of biotic resistance is needed. Importantly, when combined with our finding that Typha can persist at all nutrient levels when natives are absent, this information could help identify wetlands particularly vulnerable to invasion, especially in environments experiencing concurrent nutrient enrichment and disturbances that expose bare ground.},

This study evaluated the effectiveness and ecological impacts of two S. alterniflora management strategies in the Yangtze River estuary: Haloxyfop-R-methyl application and repeated mowing (once at the early flowering stage and once nine weeks later). The effectiveness of S. alterniflora control, and macrobenthos and bacterial community responses were compared at the Haloxyfop-R-methyl site, repeated mowing site, a control site, and a mud site during 2022-2023, and sediment physicochemical properties were also assessed. One year after Haloxyfop-R-methyl application, the density, aboveground biomass, height, and regenerated S. alterniflora were significantly reduced by 84 %, 94 %, 80 %, and 99 %, respectively. Mowing reduced the density, aboveground biomass, and height by 28 %, 78 %, and 29 %, respectively. At the Haloxyfop-R-methyl site, the biomass and Chao1 index of macrobenthos were significantly decreased compared with the control. There were significant differences in the macrobenthos community structure between the Haloxyfop-R-methyl and mowing sites compared to the control. Haloxyfop-R-methyl application and mowing did not significantly alter the α-diversity of bacterial communities but had an impact on the bacterial community structure, with the main indicator species differing among sites. Vegetation changes, sediment moisture content, total organic carbon content, and ammonium nitrogen concentration were the main factors influencing the composition of macrobenthos and bacterial communities at all sites. In summary, the Haloxyfop-R-methyl strategy better controlled S. alterniflora in coastal wetlands, while the repeated mowing strategy resulted in less disturbance of the major biological groups.},

A remote sensing device capable of detecting these species could be transformative for ecosystem protection. Here we present an electrochemical aptasensor device that can rapidly detect a protein biomarker, MUP13, from rat urine, as a proof of concept for a new surveillance system able to identify the presence of a pest in an area through detection of species-specific biomarkers. The developed electrochemical sensor provided a linear detection range from 1.68 nM to 16.82 μM, with a LoD of 2.2 nM and a sensitivity of 0.26 [log(M)][-1].

abstract = {The progression of Spartina alterniflora invasion profoundly reshapes coastal ecosystems, yet the impacts of its invasion stage-specific on native species remain understudied. The field investigation along China's Yellow Sea coast was conducted to examine how invasion stages (initial to senescing) and seasons jointly drove population dynamics of the native gastropod Littoraria intermedia. Through systematic sampling of 160 quadrats across four seasons, we quantified density shifts of L. intermedia, environmental properties, and spatial aggregation patterns using Morisita's index. The results revealed a nonlinear density response that L. intermedia peaked at 15.9 ± 4.48 ind/m[2] in autumn of the mature invasion stage, but declined in winter and spring across all stages. Invasion-induced environmental shifts exhibited stage dependency; sediment organic matter increased by 203 % (5.70 ± 0.11 to 17.31 ± 0.63 g/kg) while Chlorophyll a decreased 40 % (2.90 ± 1.19 to 1.74 ± 0.96 μg/g) from initial to senescing stages. The effects of season and invasion stage on L. intermedia density indicated that the highest density was observed in summer of the mature invasion stage of S. alterniflora. According to the Morisita index analysis, L. intermedia exhibited an aggregated distribution pattern overall; however, the spatial distribution showed a tendency toward random dispersion at both the initial and senescing invasion stages. S. alterniflora stem density and vegetation coverage were identified as primary drivers on the density of L. intermedia through stepwise regression. These findings demonstrated a "facilitation-suppression" paradox: dense S. alterniflora initially enhanced L. intermedia survival via predator refuge and microhabitat stability, yet prolonged invasion degrades habitat suitability through sediment compaction and food resource depletion.},

abstract = {In response to the depauperate biodiversity often associated with the largely homogenous surfaces of artificial structures, ecological (eco-) engineering has emerged as a tool to introduce topographic complexity to coastal development. Although relatively small-scale studies using topographically complex panels and artificial rockpools are commonplace, determining how the configuration of these interventions works over greater and more realistic spatial scales has received comparatively little attention. Given the importance of spatial variability in habitat complexity for shaping community composition and, therefore, regional diversity, filling this knowledge gap is key to enhancing the 'design catalogue' for future eco-engineering installations. Here, we manipulated topographic complexity using individual concrete panels placed into larger arrays to generate two different spatial configurations, and in doing so explore the potentially interactive roles of small-scale panel complexity and larger-scale variability on biodiversity. More topographically complex panels supported greater taxon richness and abundance than low complexity panels, whilst the complexity of the panels in interaction with their spatial arrangement within larger arrays influenced community composition between treatment groups. Our results corroborate studies showing how small-scale variation in surface topography benefits biodiversity, but we also demonstrate that spatial variability in how this complexity is deployed over larger areas impacts community composition. These effects were especially evident for the invasive non-native species that frequently colonise and dominate newly engineered coastal structures, often at the expense of natives. Given the ongoing expansion of coastal infrastructure, studies such as this that explore means of 'scaling up' eco-engineering to better represent the inherent spatial variability of natural habitats are essential to achieving biodiversity comparable to, and potentially greater than, these habitats.},

It has successfully spread to non-native habitats in North and South America, Australia, and the entire European coastline.

To reconstruct the recent colonization of the Baltic Sea and determine the most probable pathways and vectors of this expansion, molecular analysis and ecological surveys were conducted. A total of 78 sequences of a fragment of the cytochrome oxidase subunit 1 (COI) from 10 different populations from the Baltic Sea and North Sea were generated and complemented with publicly available sequences. This resulted in the estimation of a haplotype network and the calculation of genetic differentiation and diversity. The results provide the first record of an established population of P. macrodactylus in the Kiel Canal area and reveal a complex expansion of this species with multiple introductions into the Gdansk Marina. Additionally, the distribution of this species in the Baltic Sea is mainly limited to port areas, indicating that shipping, particularly biofouling on boat hulls, is the primary dispersal vector.},

These impacts may be more pronounced on urban greenspaces, yet research on the use of abundant winter-flowering plants, such as Acacia spp. and Grevillea spp., in subtropical ecosystems is limited. Our study investigated the seasonal use of floral resources by honey bees and native hover flies (Melangyna indet.) in urban greenspaces of varying urbanization levels in Sydney, Australia. We found both insect groups use similar plants, with honey bees having a higher number of interactions with plants in general, but Melangyna interacting with more plant species during some seasons. Particularly in autumn and winter, when native plants flower, Melangyna had more interactions and visited more plant species than honey bees. The overlap in floral resources used by both was higher than expected in various urbanization levels during spring and autumn. This suggests that Melangyna may play a significant role in pollination during autumn and winter, especially in highly urbanized sites. The observed differences in floral resource utilization and seasonal variations indicate that the potential effects of introduced A. mellifera on native pollinators like Melangyna may be difficult to quantify given the high number of variables and complexity of the system. Our findings underscore the importance of considering seasonal patterns and multispecies interactions in studies on the impact of introduced species on native biodiversity.},

abstract = {Historically, locally transmitted fishborne trematodiasis has not been a public health concern in the United States (US). However, the widespread introduction of the first intermediate host snail Melanoides tuberculata and 2 of the fishborne trematodes it transmits (Haplorchis pumilio and Centrocestus formosanus), along with their discovery at freshwater fishing localities throughout southern California, reveals a need to further evaluate the risk of local transmission of fishborne trematodiasis in the US. Here, we confirm that the trematode stages infectious to people (metacercariae) commonly infect and can be abundant in 7 commonly caught and eaten fish species at California fishing localities. Further, via an online social media search, we provide evidence that people throughout the US eat those same fish species in ways conducive to trematode transmission (namely, eating fish unfrozen and raw). These findings further indicate the plausibility for locally transmitted fishborne trematodiasis in the US.},

abstract = {Spiders, ubiquitous and abundant predators in terrestrial ecosystems, often are the subjects of an unjust negative perception. However, these remarkable creatures stand as unsung heroes within our ecosystems, contributing a multitude of ecosystem services critical to human well-being. Here, we describe the diverse spectrum of ecosystem services offered by spiders and their potential to inspire or directly provide nature-based solutions. Provisioning services include the versatile uses of silk-like and other materials, inspiration for biomimetic technology, medicines derived from venom, hemolymph and silk, bio-insecticides that offer eco-friendly alternatives to synthetic chemicals, food sources for various human communities worldwide, and unconventional yet increasingly valued pets. Regulating services provided by spiders extend to vital roles in pest suppression across diverse agricultural settings, mitigating diseases by curbing insect-mediated pathogen dispersal, and controlling invasive species. Supporting services offered by spiders are equally extensive, involving nutrient cycling through the breakdown of organic matter, acting as food sources for predators, or creating habitats for other organisms. Beyond their tangible contributions, spiders hold a significant cultural and spiritual heritage globally and are integral to many traditional medicine practices. They inspire contemporary culture, provide educational value, contribute to mental health improvement, evoke a sense of place, offer models for scientific discovery, and are commonly employed for monitoring biodiversity and ecosystem health. To pave the way for future research, we present suggestions for exploring and quantifying the economic value of ecosystem services by spiders. While many of these services are well established and studied from various perspectives, others harbour untapped potential. Leveraging what nature inherently provides, these nature-based solutions offer avenues to address challenges such as biodiversity erosion and societal needs. By restoring, preserving, or mimicking natural processes of spiders, we can enhance or provide essential ecosystem services, harnessing the full potential of spiders and the web of benefits they bring us.},

Here, we investigated the biomass responses of ten confamilial‌ pairs of invasive and native species to six individual and combined environmental change factors. Our results revealed a significant reduction in biomass for both invasive and native species as the number of environmental change factors increased, with invasive species demonstrating heightened sensitivity. Notably, drought and salinity exhibited particularly severe negative effects across different environmental combinations, highlighting their critical role in driving these effects. Our findings underscore the importance of understanding and predicting how intensified environmental changes impact plant invasions and overall ecosystem stability.},

However, relevant research is scarce in oasis agroecosystems, which are more sensitive to global change. We studied oasis agroecosystems in Xinjiang, China, to explore the relationship between alien plant functional traits and invasion risk. A total of 611 sites comprising 9,165 plots were surveyed, covering an area of 22,474.73 hectares. Field surveys recorded species, density, and cover of alien plants, measuring traits related to growth, reproduction, and dispersal. Invasion risk was classified into four levels based on importance values. Random forest and eXtreme Gradient Boosting (XGBoost) modeling analyzed the relationship between functional traits and invasion risk, while MaxEnt modeling predicted potential distributions. We identified 62 alien plant species from 18 families and 44 genera, with Asteraceae and Amaranthaceae being the most represented families. High-risk invasive plants shared certain functional traits-specifically, high specific leaf area (SLA) and larger seed mass-which significantly enhance their invasion potential in oasis agroecosystems. The combination of these traits correlates with increased invasion risk. By incorporating SLA into the weighting of high-risk species distributions, we predicted potential distribution areas with an AUC value of 0.981. Our study identifies key functional traits enabling alien plant invasions in oasis agriculture, enhancing understanding of invasion mechanisms. Findings provide a foundation for predicting potential invasive species and developing management strategies to mitigate impacts on agricultural productivity and ecosystem services.},

abstract = {Invasive mammal eradications are commonplace in island conservation. However, post-eradication monitoring beyond the confirmation of target species removal is rarer. Seabirds are ecosystem engineers on islands and are negatively affected by invasive mammals. Following an invasive mammal eradication, the recovery of seabird populations can be necessary for wider ecosystem recovery. Seabirds fertilize islands with isotopically heavy nitrogen, which means that nitrogen stable isotope analysis (δ[15]N) could provide a useful means for assessing corresponding change in ecosystem function. We quantified decadal changes in δ[15]N on eight temperate New Zealand islands subject in pairs to distinct mammal invasion and seabird restoration histories: invaded, never-invaded, invader-eradicated, and undergoing active seabird restoration. First, we investigated long-term changes in δ[15]N values on individual islands. Second, we used a space-for-time analysis to determine whether δ[15]N levels on islands from which invaders had been removed eventually recovered to values typical of never-invaded islands. On each island, soil, plants (Coprosma repens, Coprosma robusta, and Myrsine australis), and spiders (Porrhothelidae) were sampled in 2006/2007 and 2022, allowing δ[15]N change on individual islands over 16 years to be assessed. Combined, the samples from invader-eradicated islands provided a 7- to32-year post-eradication dataset. Change in δ[15]N was only detected on one island across the study period, following the unexpected recolonization of seabirds to an invaded island. Invader-eradicated islands generally had higher δ[15]N values than invaded islands; however, they were still lower than never-invaded islands, and there was no trend in δ[15]N with time since eradication. This, and the measurable increase in δ[15]N following seabird recolonization on one island, may suggest that δ[15]N change occurs rapidly following invader eradication but then slows, with δ[15]N values staying relatively constant in the time period studied here. Isotope and seabird population studies need to be coupled to ascertain whether plateauing in δ[15]N reflects a slowing of seabird population growth and subsequent basal nutrient input or whether the baseline nutrients are entering the ecosystem but then not propagating up the food web.},

The production of activated carbons from these invasive plants offers a sustainable approach to addressing environmental pollution in the context of wastewater treatment. Activated carbons are renowned for high adsorbability and porous structure, hence, they may be highly effective in removing contaminants including dyes. Here, we review the conversion of invasive plant biomass into activated carbons production for dye removal by the adsorption technique. Influential factors, optimization conditions, adsorption models, mechanisms, and regeneration studies were systematically discussed. Remarkably, the efficacy of activated carbons derived from invasive plants such as Leucaena leucocephala pods cactus fruit peels achieved exceptionally high adsorption capacities of 584.3-806.4 mg/g for organic dyes. We also analyzed dual benefits of transforming invasive plant biomass into high-value activated carbons for wastewater treatment and managing invasive plants. It is, therefore, suggested that this approach can satisfy the sustainable development goals and solve the current global environmental challenges.},

In the last 2 decades, biological control utilizing two species of Laricobius beetles (Coleoptera: Derodontidae) has been of focus in the widespread effort to control HWA. Recently, two species of silver flies, native to the Pacific Northwest, Leucotaraxis argenticollis Zetterstedt and Leucotaraxis piniperda Malloch (Diptera: Chamaemyiidae), are being investigated as additional biological control agents. Releasing these two silver fly species in the eastern United States has yet to result in the establishment of these predators. During laboratory studies, Leucotaraxis larvae excreted a black substance in response to being disturbed, which contained anthraquinones previously detected in HWA. Previous research on Laricobius spp. found that the beetles likely sequestered these compounds from HWA. These compounds are feeding deterrents in other insect species. Leucotaraxis argenticollis life stages, their excrement, and honeydew produced by HWA were collected and analyzed by gas chromatography-mass spectrometry. Results showed that these anthraquinones were detected in various life stages of Le. argenticollis immatures and adults that fed on HWA. They were not detected in Le. argenticollis adults that were only fed artificial diet and water, indicating that Le. argenticollis sequesters the anthraquinones from HWA and may transmit the compounds to their eggs.},

Despite its biogeographic significance as a transitional zone between the Yangtze and Yellow River floodplains, this region remains one of China's most understudied and ecologically degraded freshwater systems. Historical pollution events and contemporary anthropogenic pressures - agricultural intensification, hydrological fragmentation and invasive species - have severely compromised wetland integrity. During mid-December 2005 and November to December 2006, standardised surveys employed fixed-radius point counts (158 sites) with the component counting method to enhance accuracy.

NEW INFORMATION: We present the first comprehensive waterbird dataset for the Anhui and Jiangsu part of the Huai He floodplain, comprising 44 species (32,517 individuals) recorded across 30 wetlands during 2005-2006 surveys. All occurrence data adhere to Darwin Core standards and are accessible via the Global Biodiversity Information Facility, providing spatial-temporal baselines for abundance and distributional data for waterbirds in this region.},

Limited data exist on this species acting as a pseudoparasite, with only 3 documented cases found on literature review of Bipalidae species living inside human hosts. We present one such case from Shreveport, Louisiana, of a patient who arrived at the emergency department after a hammerhead worm was expelled from his sinus passage. A 13-y-old male with a history of autism and developmental delay had been complaining of headache for 2 to 3 d. He had a spontaneous nosebleed from his right nostril on the morning of presentation to the emergency department. On blowing his nose, a large hammerhead worm was evacuated from his sinuses. Imaging studies and direct visualization did not reveal any significant damage or remaining helminths in the sinus passages. Due to patient risk factors for parasitic infection, while definitive identification of the worm species was still pending, a course of albendazole was prescribed. The patient was discharged from the emergency department in good condition. As this invasive species becomes more common in warm and humid areas of the United States, infection with these pseudoparasites may become more prevalent as well. Fortunately, this appears to be a rare occurrence, and clinical sequelae appear to be minimal after removal of the organism.},

In this study, the effects of key eco-environmental factors including biomass, water temperature, and pH that influence eDNA shedding and decay of golden mussel were revealed through field investigations of grand water diversion project and laboratory experiments. The results revealed significant positive correlations between both biomass and water temperature with eDNA shedding rates. Additionally, high water temperatures and low pH conditions were found to accelerate the decay of mussel eDNA. The findings of this study indicate that the effects of these controlling factors should be considered during the collection and quantitative analysis processes of water samples to provide reliable base for invasion detection using eDNA technology.},

The potential distributions of introduced mangrove plants (Laguncularia racemosa and Sonneratia apetala) were assessed to evaluate their suitability for mangrove restoration. Furthermore, we investigated the invasive potential of Spartina alterniflora, a biologically invasive species in mangrove ecosystems, under different climate scenarios. Finally, a conservation gap analysis was conducted to identify priority areas for mangrove protection. We observed the following: i) main environmental factors affecting the distribution pattern of mangroves in Guangdong Province were temperature and water quality; ii) hotspots of mangrove distribution are mainly concentrated in the Beibu Gulf coastline, Leizhou Gulf coastline, Zhenhai Bay-Dongping Harbor-Beijin Bay coastline, Zhuhai Harbor-Guangzhou Bay-Humen-Mawan Bay, Shuangyue Bay, and Rongjiang River estuary; iii) optimal zone of mangroves was the largest under the SSP5-8.5 scenario, and the potential suitable zone and geometric center of mangroves gradually shifted to higher latitudes; iv) the protection and restoration of mangroves should be prioritized in the future in the zones of Anpu Harbor, Leizhou Bay, Zhenhai Bay, and Huangmaohai and coastline of Pearl River Estuary.},

However, land utilization practices such as mowing, grazing, and mining have led to degradation, affecting plant diversity and reducing carbon (C) and nitrogen (N) stocks. Revealing these degradation mechanisms after various land utilization practices is essential for implementing effective management practices to restore and sustain degraded grasslands. This study examines the effects of different land use types-mowing, light grazing, heavy grazing, and mining-on plant community characteristics, biomass, soil C and N dynamics in the Hulunbuir Grassland of Inner Mongolia. Our results revealed that across 50 herbaceous species, dominant vegetation shifted significantly: light grazing favored native grasses like Cleistogenes squarrosa and Artemisia frigida, while heavy grazing and mining promoted invasive species (e.g., Taraxacum mongolicum). Plant diversity and biomass were highest under mowing, but mining reduced species richness by 35 % and biomass by 50 % compared to mowing. Soil organic carbon (SOC) and total nitrogen (STN) stocks varied significantly across land-use types and plant growth phases, peaking in mowing sites (SOC: 9.85 ± 1.45 g/kg; STN: 1.55 ± 0.05 g/kg at 0-20 cm depth) and declining sharply in mining areas (SOC: 3.44 ± 0.46 g/kg; STN: 0.76 ± 0.06 g/kg). Strong correlations linked plant diversity and root biomass to SOC and STN retention, whereas Asteraceae biomass showed minimal influence. Structural equation modeling demonstrated that land use influenced SOC and STN stocks primarily through indirect effects on plant, root, and litter biomass rather than direct impacts. These findings underscore the need for daptive, site-specific restoration frameworks to mitigate degradation, prevent invasive species encroachment in mining areas and grazing livestock for sustainable grassland restoration.},

Emergent habitat shifts towards invasive seaweeds, facilitated by global warming, can also be at play, having still unknown effects on seahorse ecology. Particularly, indirect impacts on seahorse populations via altered predation success remains largely unexplored. Here, we conducted mesocosm experiments to investigate differences in the prey capture success of the long-snouted seahorse (Hippocampus guttulatus) among native habitats (i.e. seagrass meadows and unvegetated sediments) and non-native Caulerpa prolifera meadows when offered different preys (amphipods and shrimps), at low or high prey availability, and under low or high habitat complexity. Great plasticity of H. guttulatus to all habitats was revealed, as habitat type did not significantly affect the capture success. Instead, capture success depends on prey identity and availability regardless of the habitat type, as well as on habitat complexity. Seahorse capture success was higher under high prey availability, as well as when predating on amphipods that were offered together with shrimps. High habitat complexity of both vegetated habitats enhanced by double the capture success, whereas an opposite effect of similar magnitude was found for more complex unvegetated habitats. This indicates that vegetation complexity, regardless their native or invasive nature, reduces prey awareness to predator, whereas small structures in unvegetated habitats provide refuge for preys but not seahorse camouflage. We found no evidence that shifts from native habitats to invasive C. prolifera negatively impact H. guttulatus capture success, but further research on other aspects of its feeding ecology is still necessary.},

One particularly impactful disruption of the environmental context is the invasion of alien species into a community. While PSF between native and non-native species has been linked to invasion success, the effect of an invader on PSF between resident plants has received little attention. We explored how Pinus contorta (lodgepole pine) invasion impacts PSF between four resident grasses (two native and two non-native species). We grew the plants in live soil to condition species-specific soil communities, followed by a response phase where the plants were grown in conspecific and heterospecific soil. Both phases were performed with soil from uninvaded, invaded, or controlled invasion areas. Pairwise PSF between the species in uninvaded soil was negative and became neutral to positive in invaded soil. This effect persisted even after P. contorta removal. Our results suggest a destabilizing effect of P. contorta invasion on the coexistence of the resident grasses, benefitting non-natives over natives. This work exemplifies an overlooked mechanism by which an invader can alter interactions between resident species and adds a novel dimension to the context dependence of PSF.},

Providing one of the first-large scale assessments of their impacts, our study identified wild pigs as a source of non-point pollution on both a regional and multi-regional scale within our selected study state through microbial source tracking and traditional water quality assessment. At a multi-regional scale, we found greater median concentrations (mg/L) of nitrate (95.7%; p < 0.001), magnesium (83.3%; p < 0.001), and potassium (84.7%; p < 0.001) in samples from streams with fecal contamination by wild pigs (n = 111) than from streams without (n = 115). Like other non-point pollutants, the effects of wild pigs on water quality are scale-dependent and differ significantly across regions. Finally, at both a regional and multi-regional scale, our study found observably greater Escherichia coli and fecal coliform concentrations in streams with wild pigs, though statistical significance was lost at scale. Future research will be necessary to continue to evaluate the impacts of wild pigs on water quality, especially across different scales.

abstract = {Understanding habitat use and abundance is essential for elucidating the impact of invasive species. Invasive carnivores affect ecosystems by preying on native animals. In Japan, the Japanese weasel (Mustela itatsi) is native to the mainland but has been intentionally introduced to many small islands, including Miyakejima Island. We investigated the habitat use and abundance of invasive non-native Japanese weasels on Miyakejima Island via fecal surveys, and for comparison, performed similar surveys for their native conspecifics on Izu-Oshima Island. We constructed a generalized linear mixed model and estimated fecal abundance across the entire island based on the effect of vegetation type on their abundance. On Miyakejima Island, deciduous broadleaf and bamboo forests had positive effects on weasel abundance, whereas grasslands had a negative effect. Conversely, on Izu-Oshima Island, bare ground had a negative effect. Further, the estimated average fecal abundance across Miyakejima and Izu-Ohshima Islands, considering vegetation type, were 7.44 and 4.89 feces samples per km, respectively, suggesting that weasels are well adapted to Miyakejima Island. We also analyzed the fecal DNA of weasels in a specific area on Miyakejima Island and estimated non-native weasel density at 20 individuals per km2 (95% CI: 4.9-80) using genetic capture-recapture methods in the area. These findings enhance understanding regarding non-native species and may facilitate the formulation of countermeasures for their control.},

However, demographic stochasticity in low-density range-edge populations and stochastic long-distance dispersal may disrupt the synchronisation of range expansion. Here, we investigate whether rates of spread by an invasive species, the spongy moth and exhibit spatial synchrony. We also evaluate if climatic oscillations at multi-annual timescales arising from teleconnections synchronise spread at similar timescales. We applied extensions of wavelet analysis to spatiotemporal data on climate variables and range-edge abundances during 1990-2020. Synchrony in spread occurred throughout the entire study area, but only in the northernmost and southernmost ecoregions was synchrony in spread explained by multi-annual climate oscillations linked to teleconnection patterns. We demonstrate spatial synchrony in invasive spread and find an opportunity to predict the timing of pulses of invasive spread at regional scales.},

Bidens pilosa L., a globally invasive weed originating in tropical America, severely impacts agricultural productivity by infesting 31 economically vital crops across over 40 countries. This study examined the global distribution of Bidens pilosa L., under current and future climate scenarios. Using species distribution models and occurrence data, we identified key factors influencing its spread, including temperature, precipitation, and human influence. Our findings suggest a likely decline of suitable habitats in tropical regions and an expansion into temperate regions, with climate suitability decreasing under higher temperatures. Additionally, historical reconstructions emphasize that the rapid spread of the species was facilitated by maritime trade routes. Management strategies are proposed that emphasize the need for enhanced control measures in high-risk areas and conservation efforts in its native range in tropical America. Overall, this research contributes to understanding the dynamics of B. pilosa distribution and informs proactive management strategies to mitigate its ecological and economic impacts.},

abstract = {Movement is a key driver of population dynamics. Movement ability and propensity often vary among populations and individuals. These differences may be particularly strong in aquatic species, where the ability to move within a site is not necessarily correlated to the ability to move between sites. In periods of range expansion, these differences can lead to non-equilibrium dynamics, whereby more mobile phenotypes arrange themselves spatially. This can be even more pronounced when dispersal success is nonrandom with respect to a heritable trait, thus acting as an agent of selection. This process-dubbed spatial sorting-can be particularly pronounced in non-native species, often hastening the speed of invasion spread. However, before spatial sorting occurring, there must first be individual differences in traits that confer greater movement success. Recently, a high-density breeding and expanding population of the non-native pipid frog, Xenopus tropicalis, in west-central Florida, offering a great opportunity to test whether movement success is predicted by individual differences in morphology or locomotor capacity. To test this, we compared the morphology, maximal exertion capacity, and jumping performance of movers and residents. We found that relative to residents, movers had longer hindlimbs, wider ilia, and traveled for greater time intervals before reaching exhaustion. These results suggest functional morphological and physiological traits are important in determining inter-site movement success.},

abstract = {Coastal ecosystems surrounding the Korean Peninsula are undergoing rapid environmental changes driven by global climate warming, highlighting the need for efficient methods to monitor marine biodiversity. This study aimed to analyze fish communities across four coastal regions: the East Sea, South Sea, West Sea, and Jeju using environmental DNA (eDNA) metabarcoding. Underwater drones were employed to collect water samples. A total of 63 sampling sites were surveyed, detecting 167 fish species from 72 families, encompassing tropical, subtropical, temperate, boreal, polar, and deep-water taxa. The East Sea hosted a mix of cold- and warm-water species, while Jeju exhibited a relatively high proportion of tropical and subtropical fish. Additionally, 13 alien species were identified, underscoring the utility of eDNA for the early detection of non-native taxa expanding their ranges in response to ongoing warming trends. This study further validated that eDNA sampling using underwater drones offers a rapid, non-invasive approach to biodiversity assessments, effectively addressing many of the limitations associated with traditional survey techniques. Collectively, these findings highlight the potential of eDNA to generate critical and timely data on fish assemblages the emergence of alien species, providing valuable insights to inform proactive resource management, and climate change research in marine ecosystems.},

abstract = {Mangrove sediments host diverse microbial communities that are crucial for carbon fixation, but their functions and pathways in subtropical ecosystems-particularly under Spartina alterniflora invasion and across varying sediment depths-remain unclear. This study employed metagenomic and qPCR analyses to explore microbial carbon fixation in Rhizophora stylosa, S. alterniflora, and bare beach habitats. Environmental factors like Cd, sulfide, pH, and salinity significantly influenced carbon fixation and sulfate reduction. Specifically, the invasion increased the abundance of key carbon fixation genes, including aclA/B, cbbL, and korA, which are involved in the Calvin-Benson-Bassham (CBB) and Arnon-Buchanan (rTCA) cycles, respectively. This shift in gene abundance was accompanied by elevated Ribulose-1,5-bisphosphate carboxylase/oxygenase (RubisCO) activity (0.47-21.82 nmol CO2 g[-1] soil min[-1]), suggesting a potential increase in microbial CO2 fixation rates in S. alterniflora-invaded sediments. Sediment depth also affected the distribution of carbon fixation genes and carbon-metabolizing microbes. Desulfobacterota were identified as major contributors to carbon fixation via both the rTCA and CBB cycles. Moreover, a strong correlation was observed between carbon fixation and sulfate reduction. These findings reveal how S. alterniflora invasion impacts carbon fixation and enhance our understanding of the mangrove ecosystems' role in climate change regulation.},

The aim of this research was to determine: (1) the selenium content of the specimens of these species and the soils in which they grew, (2) the role of habitat parameters in shaping selenium levels in the soil and the plants studied, and (3) the bioaccumulation potential of the plants studied, taking habitat conditions into account. Specimens of both species were collected from riverbanks in Poland and Montenegro, and the Se concentrations in each specimen and in the soil sample from each site were measured. Our studies indicate that the invasive species B. frondosa has significantly higher selenium concentrations and greater bioaccumulation abilities (BCF > 1) compared to B. tripartita. Despite the average selenium concentration in the soil being higher in Poland than in Montenegro, Se concentration accumulated in B. frondosa collected in Montenegro was higher, it was also observed that soil chemical properties affect Se bioaccumulation in this species. The type of land use within each site has also been identified according to CORINE classification. The results of the study indicated a great significance of human impact on the selenium enrichment of plants, as the specimen collected in artificial rivers and areas impacted by anthropogenic pression contained much higher amounts of Se than plants growing in more natural habitats. The results also illustrated that the invasive species that have the ability to accumulate selenium, like B. frondosa, can be an exogenous root of this particular trace element for living organizms.},

However, its genome has not been previously characterized. To address this, we assembled a high-quality chromosome-scale genome for B. semifasciolatus using High-Fidelity (HiFi) sequencing and Hi-C technology. The resulting haplotype-resolved assemblies, spanning 776 Mb and 779 Mb across 25 chromosomes, achieved genome coverages of 99.5% and 99.7%, respectively, and included four gap-free chromosomes. Genome quality assessment using BUSCO indicated a high completeness score of 98.2% for haplotype1 and 98.3% for haplotype2, further validated by strong synteny with the zebrafish (Danio rerio), confirming the assembly's integrity and continuity. Through integration of full-length transcriptome data, RNA sequencing, and homology-based annotation, we identified 26,057 protein-coding genes with 2,087 pseudogenes in haplotype 2, and 25,622 protein-coding genes with 2,101 pseudogenes in haplotype 1. This high-resolution genome assembly is a crucial resource for advancing research in the Cyprinidae, particularly for understanding adaptive evolution in extreme environments.},

abstract = {Exploitation of host resources by parasites can have profound impacts on infected hosts. When prevalence is high parasite infection can even feed back on host population dynamics. Especially when parasites are invasive species, their new native hosts can suffer from exploitation due to a lack of co-evolutionary history. Nevertheless, energetic costs are often subtle at the level of the individual and hard to link to population level effects. Sublethal energetic costs accumulate over time and can in sum be traded off against fitness over longer time scales. To study temporal accumulation of infection costs, we used a series of controlled infection experiments to assess the physiological effects exerted by the invasive parasitic copepod Mytilicola intestinalis on its newly acquired native host, the blue mussel Mytilus edulis in the North Sea, where the parasite can reach prevalences > 70 %. To link short-term physiological responses to long term components of fitness, we combined several methodological approaches measuring changes of physiological traits that act on different time scales. Stable isotope analyses over different seasons and environments revealed a direct consumption of host tissue by M. intestinalis. Tissue repair increased energy demand that could directly be observed in accelerated heartbeat rates, and changes of amino acid metabolism measured by [1]H NMR spectroscopy. Although these effects were comparatively small in size, the resulting altered energy budget of the mussel host led to a lower body condition index under controlled laboratory conditions on medium time scales (months) and slower growth in the field over longer time scales (1 year). In combination, our experimental results show that small short-term physiological changes can translate to fitness relevant negative effects on life history traits when integrated across temporal scales.},

Despite similar underlying data, Grinnellian niches are modelled with species-distribution models (SDMs), whereas Eltonian niches are modelled with ecological-network analysis, mainly because the sparsity of species-interaction data prevents the application of SDMs to Eltonian-niche modelling. Here, we propose to adapt recently developed joint species distribution models (JSDMs) to data on ecological networks, functional traits, and phylogenies to model species' Eltonian niches. JSDMs overcome sparsity and improve predictions for individual species by considering non-independent relationships among co-occurring species; this unique ability makes them particularly suited for sparse datasets such as ecological networks. Our Eltonian JSDMs reveal strong relationships between species' Eltonian niches and their functional traits and phylogeny. Moreover, we demonstrate that JSDMs can accurately predict the interactions of species for which no empirical interaction data are available, based solely on their functional traits. This facilitates prediction of new interactions in communities with altered composition, for example, following climate-change induced local extinctions or species introductions. The high interpretability of Eltonian JSDMs will provide unique insights into mechanisms underlying species interactions and the potential impacts of environmental changes and invasive species on species interactions in ecological communities.},

Two distinct and purely clonal lineages of the sudden oak death pathogen Phytophthora ramorum recently emerged in forests in the Western United States, providing the unique opportunity to study a naturally replicated invasion into the same ecosystem. We characterized population genomic patterns during early invasion using whole genome sequencing of two P. ramorum clonal lineages sampled in the first five years following their detection. We re-sequenced genomes from populations of two dominant clonal lineages, NA1 (n=134; 2001-2005) and EU1 (n=160; 2015-2019), and obtained 106,070 high-quality SNPs in genic regions. Our results are consistent with the hypothesis of one introduction for each lineage. The NA1 population had a wider distribution of pairwise genetic distances than EU1 and higher genetic diversity, though neither NA1 nor EU1 populations clustered clearly by year. There was significant correlation between genetic distance and geographic distance for NA1 (p = 0.042), but not for EU1 (p = 0.402). The genetic diversity in NA1 is strongly driven by loss of heterozygous positions, which impacted more than one-third of the sampled NA1 population. However, loss of heterozygosity was rare in EU1. This work provides novel insights into the invasion biology and dynamics of clonal plant pathogens in natural ecosystems.},

abstract = {BACKGROUND: Fire blight (Erwinia amylovora), a devastating bacterial disease, has posed significant challenges to apple and pear production for more than a century. In recent years, the spread of fire blight to China via Xinjiang has heightened concerns among planters and government authorities, particularly given the region's distinct geography and climate, underscoring the urgent need for innovative biocontrol strategies.

RESULTS: This study introduced a predatory bacterium, Herpetosiphon tianshanensis sp. nov. NSE202, isolated from natural forest soil in Xinjiang, China, that could be a new type of promising biological control agent for the management of fire blight. Strain NSE202 differs from the five other reported Herpetosiphon species in terms of its physiological characteristics and genomic composition. Using morphological, 16S ribosomal RNA gene and whole-genome analysis, the NSE202 strain was assigned to H. tianshanensis sp. nov. Strain NSE202 demonstrated strong predatory capability against Erwinia amylovora (Ea) in vitro. The biocontrol capacity of NSE202 was assayed on isolated inflorescences of fragrant pear and biennial potted pear seedlings under greenhouse conditions. The protective control efficacy of NSE202 was 64.8% in the inflorescences assay. Bacterial spraying of NSE202 significantly reduced the incidence and disease index on pear seedlings with protective and therapeutic control efficacies of 71.9% and 61.5%, respectively. Strain NSE202 demonstrated stable colonization on pear blossoms and twigs under greenhouse conditions. The pathogen population was suppressed significantly in planta treated with NSE202, as shown by colony counts on plates, scanning electron microscopy, and quantitative polymerase chain reaction analysis. Further investigation demonstrated that secondary metabolites of strain NSE202, collected via macroporous resin, and extracellular proteins, precipitated using ammonium sulfate, had pronounced lytic activity against the fire blight pathogen. In addition, certain lipases, glycoside hydrolases, and peptidases secreted by strain NSE202 may contribute significantly to the predation process. These findings suggest that such components may serve as promising biocontrol factors.

CONCLUSIONS: The discovery of H. tianshanensis sp. nov. NSE202 provides a new and promising strategy for combating fire blight. The isolates' multiple capacities to colonize and exert antagonistic effects against Erwinia amylovora makes them highly promising candidates for an integrated biological solution. © 2025 Society of Chemical Industry.},
