The comparative functional response approach-an experimental method measuring feeding efficiency of a predator along a prey gradient-can forecast ecological impacts of an invader by quantifying its resource consumption under varying conditions. This approach was applied to the Tench <i>Tinca tinca</i>, an invasive benthivorous fish currently spreading in the St Lawrence River, and two native benthivorous species, the White Sucker <i>Catostomus commersonii</i> and the Brown Bullhead <i>Ameiurus nebulosus</i>. Body condition was used as a measure of long-term fitness under a given temperature treatment, and the Functional Response Ratio (FRR) and Relative Impact Potential (RIP) were used as metrics describing trophic impact. All species were acclimated to 18 °C and 25 °C; the former temperature represents the physiological optimum for the chosen native species, whereas the latter temperature is the projected near-future mean summer maximum for the lower Great Lakes. Feeding rates on larval chironomids were measured in 3-h trials at prey densities ranging from 2 to 500. White Sucker feeding efficiency was unaffected by temperature and consistently higher than the Tench, whereas the Tench exhibited a lower maximum feeding rate at 25 °C compared to 18 °C. Despite superior feeding rates, White Suckers showed diminished body condition at the elevated temperature, suggesting their foraging advantage might not persist under warming conditions. These findings suggest Tench possess greater thermal compensation capacity than White Suckers, indicated by their stable condition factors at elevated temperatures despite lower maximum feeding rates. In a second set of experiments, Tench achieved greater feeding efficiency than Brown Bullhead, but both species showed reduced efficiency at elevated temperatures. However, Brown Bullhead had increased body condition indices following experiments. FRR and RIP metrics indicated that Tench holds a competitive feeding advantage over Brown Bullhead that is reduced under elevated temperatures. Tench impact depends on both feeding efficiency and its capacity to maintain fitness in warm waters. Our results highlight the necessity of considering thermal adaptation in ecological forecasting. Climate warming may reshape competitive dynamics and ecosystem impact pathways beyond direct consumption effects.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s10530-026-03767-w.</p>","PeriodicalId":9202,"journal":{"name":"Biological Invasions","volume":"28 2","pages":"51"},"PeriodicalIF":2.7,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12901266/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146200260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we examine shifts in news media discourse surrounding the fall armyworm invasion across Africa, Asia, and Oceania to investigate such cascades. We apply topic modeling to 570 news articles to quantify spatial and temporal changes in the prevalence of 33 topics related to fall armyworm invasion discourse. We grouped these topics into broader thematic categories and determined their prevalence during three general invasion phases. We found that the sequence of prevalent thematic categories was consistent across news articles from the three continents analyzed. The first years of invasion discourse are dominated by topics related to a preparation-oriented 'Surveillance' phase, followed by those related to an 'Impact' phase, and finally a response-centered 'Control' phase. However, the duration of the 'Impact' phase differs by continent, lasting 3 of the 7 years analyzed in Africa, but only 1 of 5 and 1 of 3 in Asia and Oceania, respectively. Also in Oceania's news discourse, invasion preparation features more prominently with a relative theme proportion of 0.722 in the first year after detection (Africa = 0.387, Asia = 0.259). These differences in phase duration and emphasis align with described patterns of the invasion progression and outcomes across regions. These regional variations highlight the potential of text analysis of news media for tracking cascading dynamics of emerging pests. In turn, these approaches can inform more targeted management and mitigation strategies.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s10530-026-03887-3.</p>","PeriodicalId":9202,"journal":{"name":"Biological Invasions","volume":"28 8","pages":"176"},"PeriodicalIF":2.7,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13385020/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148547936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Native fish species occupancy was uneven while invasive non-native fishes were widely distributed and represented over 40% of the overall species richness.

Flow barriers, high abundance of competitive catfish, and increased water turbidity suppressed black bass predation and influenced fish-community dynamics, allowing an endangered native species, the Berg-Breede whitefish (<i>Cheilobarbus capensis</i>), to persist at extremely low frequencies. Thereby, we show empirically that the ecosystem engineering behaviours of the turbidity-adapted sharptooth catfish suppress the high predatory impact of visual predators, black basses.

Most studies focus on the biological invasion of single species, and only in recent years has it been realized that multi-species interactions that involve native and invasive host species and their microbial symbionts can play important roles in determining invasion outputs. A theoretical framework that treats these interactions and their impact is lacking. Here we offer such a framework and use it to explore possible dynamics that may emerge from the sharing of native and non-native symbionts among native and non-native host species. Thus, for example, invasive plants might benefit from native microbial communities in the soil, or might be particularly successful if they carry with them parasites to which competing native hosts are susceptible. On the other hand, invasion might be hindered by native parasites that spread from native to invasive individuals. The mathematical framework that we present in this study provides a new mechanistic, cohesive, and intuition-enhancing tool for theoretically exploring the ways by which the subtleties of host-microbe relationships can influence invasion dynamics. We identify multiple pathways through which microbes can facilitate (or prevent) host invasion, microbial invasion, and the invasion of both hosts and their co-introduced microbes. We disentangle invasion outcomes and suggest possible ecological dynamics that may be underexplored in current invasion biology literature. Our work sets the foundations for invasion theory that includes a community-level view of invasive and native hosts as well as their microbial symbionts.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s10530-025-03711-4.</p>","PeriodicalId":9202,"journal":{"name":"Biological Invasions","volume":"27 12","pages":"253"},"PeriodicalIF":2.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12642807/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145602477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, an invasion by the round goby in 2013 led to a significant decline across all gastropod families, disproportionately impacting soft-shelled and shallow-dwelling species, while other species, including invasive dreissenids, partially recovered 3-7 years after the goby invasion. This mollusc recovery was depth-related and was limited to deeper areas. Altogether, molluscan communities were sensitive to ecosystem change and invasives species, with some invaders offsetting the impacts of eutrophication and habitat alterations.

We found that naturalized species have higher climatic suitability compared to non-naturalized ones. Additionally, seed mass, plant height, short-lived herbaceous growth form, and native range size are positively associated with naturalization success.
