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. Dovetailing mechanisms influence stomatal adaptation to climate across a wide-ranging species.","PeriodicalId":161,"journal":{"name":"Ecology Letters","volume":"29 9","pages":""},"PeriodicalIF":7.7,"publicationDate":"2026-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ele.70453","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148973339","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}

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.

Through site-training scenario, leaf-to-canopy scaling and spectral-domain modelling tests, we find that reliable canopy trait retrieval depends not only on trait and spectral coverage, but also on preserving trait-spectral relationships across sites and scales. Spectral predictions recovered observed multivariate covariation, summarizing crown variation into a leaf-economics dimension and two additional biochemical dimensions related to hydro-thermal regulation and defence/metabolism. Mapping these dimensions revealed distinct community-level trait organization alongside substantial species- and crown-level variation within forests.

Using a global database covering 142 communities across ten terrestrial biomes, we examined canopy effects on taxonomic and phylogenetic diversity at global and local scales, quantified with Hill numbers (q = 0, 1, 2) to weight rare, common, and dominant species. Globally, canopy microsites hosted five times more exclusive species and over three times more evolutionary history than open ground. Locally, canopies buffered aridity's negative effects, sustaining higher diversity. For q = 1, open ground had higher diversity under low aridity, but under dry conditions canopies promoted rare, stress-sensitive species alongside dominants. These patterns show that canopy plants act as microrefugia, preserving both species richness and evolutionary history, highlighting their critical role as guardians of plant diversity under increasing climatic aridity.","PeriodicalId":161,"journal":{"name":"Ecology Letters","volume":"29 8","pages":""},"PeriodicalIF":7.7,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13506208/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148816748","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}

Although temporal stability in populations is posited to emerge from the interplay between intrinsic and extrinsic factors, the nature of these interactions remains poorly understood. Here, we analysed abundance time-series for 7912 populations from 287 fish species across 1557 streams spanning multiple biogeographic realms. We evaluated how species traits interact with environmental and biotic contexts to shape temporal stability. Populations were most stable among equilibrium-strategist species, at higher trophic positions and with lower dispersal abilities. Temporal stability was also greatest near species' thermal and flow niche centers and in less speciose communities, with life-history traits modulating these effects. Notably, the effects of environmental variability were less pronounced and contingent on species traits. Our findings provide empirical evidence that interspecific trait differences are key determinants of temporal stability, highlighting the value of trait-based approaches for generalizing biodiversity dynamics.","PeriodicalId":161,"journal":{"name":"Ecology Letters","volume":"29 8","pages":""},"PeriodicalIF":7.7,"publicationDate":"2026-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ele.70443","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148754470","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}
