In freshwater ecosystems, the relationship between body size and biomass provides a powerful tool for characterizing community structure and trophic transfer efficiency. While these relationships are well established at the whole-community level, responses within plankton functional groups with distinct ecological characteristics have yet to be explored. In this study, we analysed plankton biomass-size relationships across > 550 Canadian lakes. For phytoplankton, we found that mixotrophs exhibited positive biomass-size slopes, while autotrophs exhibited negative slopes. For zooplankton, herbivores exhibited relatively flat slopes, while non-herbivores exhibited negative slopes. Biomass-size relationships also differed among lake trophic states, but only for phytoplankton functional groups. This work should improve predictions and assessments of freshwater ecosystem functioning and food web pathways, based on our observation of directional shifts in biomass-size relationships across functional groups and trophic states.","PeriodicalId":161,"journal":{"name":"Ecology Letters","volume":"29 10","pages":""},"PeriodicalIF":7.7,"publicationDate":"2026-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ele.70458","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149086870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Using a long-term dataset comprising > 1.3 million individuals of 728 carabid and spider species, we quantified temporal trends in functional diversity across forests, grasslands and croplands. Trajectories diverged strongly among land uses: functional richness increased in forests and grasslands but declined sharply in croplands. In forests, communities became more specialised and less redundant, suggesting increasing niche differentiation, but experienced greater functional richness loss under simulated species extinctions. Cropland assemblages became functionally homogenised. Losses of key effect traits among spiders suggest potential erosion of ecosystem functions in croplands. Moreover, genera dominated by species with unique trait combinations were typically larger-bodied and less dispersive, and their loss would remove irreplaceable functional strategies from communities. Overall, our study reveals diverging long-term trajectories of arthropod functional diversity across land uses, indicating potential negative consequences for ecosystem functioning in arable landscapes.","PeriodicalId":161,"journal":{"name":"Ecology Letters","volume":"29 9","pages":""},"PeriodicalIF":7.7,"publicationDate":"2026-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ele.70457","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149033096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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 set up a diversity experiment, based on 20 aquatic microcosms where we grew one, two, three or four moss species together, to test whether coexistence amongst species is an important driver of high-dimensional elementome shifts in mixed communities. Our results provide experimental evidence showing that species tend to shift their elemental composition in response to coexistence, and that the magnitude of this shift increases with the elemental diversity of the community. Overall, our results provide the first experimental evidence of high-dimensional shifts in elementomes due to coexistence, supporting the biogeochemical niche hypothesis.","PeriodicalId":161,"journal":{"name":"Ecology Letters","volume":"29 9","pages":""},"PeriodicalIF":7.7,"publicationDate":"2026-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ele.70456","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149009908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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, it could also pose pathogen risks, especially from phylogenetically close carcass-scavenger pairs sharing traits that facilitate transmission. Although phylogenetic distance has long been suggested to influence scavenger feeding patterns, evidence remains scarce and limited at specific scales. To address this gap, we used camera-trap monitoring to record scavenging events on fish, bird, and mammal carcasses in a Mediterranean wetland and evaluated how phylogenetic distance between vertebrate scavengers and available carcasses shaped feeding patterns. Our results revealed a consistent pattern across the assemblage, showing that scavengers consumed carcasses that were more phylogenetically distant than expected by chance, although this pattern varied slightly between taxonomic classes and at the species level. Our findings suggest the existence of a natural mechanism by which scavengers may reduce pathogen exposure when selecting carcasses.","PeriodicalId":161,"journal":{"name":"Ecology Letters","volume":"29 9","pages":""},"PeriodicalIF":7.7,"publicationDate":"2026-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ele.70455","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149010052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Thus, the anatomical maximum stomatal conductance, gmax, is a key influence on gas exchange, growth and productivity. For 145 geographically diverse ecotypes of Arabidopsis thaliana grown in a common garden we tested hypotheses for the drivers of variation in gmax and a stomatal size-density trade-off, considering epidermal optimization, epidermal development and climate adaptation. Ecotypes native to colder and drier macroclimates had higher gmax, consistent with leaf-scale stress-avoidance, despite having longer times to flowering. A high gmax was achieved through greater epidermal allocation to stomata, via both increased guard cell initiation and smaller epidermal pavement cells. Stomatal traits showed polygenic associations with climate. A weak stomatal size-density trade-off was observed for only the abaxial surface, consistent with flexible constraints on stomatal development and independent trait adaptation.

We subjected clonal individuals to a critical ecological challenge—the threat of predation—to disentangle the developmental mechanisms of individuality. Predation may erode or amplify among-individual differences, demonstrating that individuality is developmentally plastic. If individuality is instead determined before birth, it should resist environmental influences. We tracked behaviours of genetically identical fish (Amazon mollies), reared with or without predation stress, continuously from birth for 4 weeks. While predation shifted mean-level behaviours, the magnitude of individuality was unaffected, indicating that individuality crystallizes robustly over time under stress and without genetic variation. Surprisingly, maternal identity strongly shaped swimming velocity but not refuge use, suggesting distinct developmental mechanisms for different ecologically relevant behaviours. We show that individuality persists despite ecological stress and is seeded before birth through non-genetic factors. Even in the face of a shared environmental challenge, the behavioural trajectories of individuals are unique.","PeriodicalId":161,"journal":{"name":"Ecology Letters","volume":"29 9","pages":""},"PeriodicalIF":7.7,"publicationDate":"2026-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ele.70454","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148964307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Over 20 years, the stabilising effects of biodiversity strengthened, driven mainly by increasing asynchrony in species-specific dynamics rather than shifts in interaction-dependent effects. While biodiversity's stabilising effect initially increased alongside productivity, this coupling weakened over time as interaction-dependent effects on productivity and stability became decoupled.
