However, current approaches to heat tolerance either overlook the duration of heat exposure or describe temperature-time relationships without characterizing causal mechanisms, constraining hypothesis testing and prediction under novel conditions. Heat inactivation of photosynthesis has been posited to result from protein denaturation or lipid membrane breakdown, but their relative contributions are not well resolved. Here we develop and test a quantitative theory of photosynthetic heat inactivation based on chemical kinetics and use the theory to evaluate these competing mechanisms. By analysing photosystem II temperature responses in 177 plant species from 157 families, we show that protein denaturation, not lipid membrane breakdown, governs heat tolerance. The theory also predicts an upper acclimatization limit of ~60 °C, set by the thermal stability of heat shock proteins and supported by global data for 826 species. Our findings provide a predictive, mechanistic basis for photosynthetic heat tolerance and the thermal limits of the biosphere in a changing climate.","PeriodicalId":18835,"journal":{"name":"Nature ecology & evolution","volume":" ","pages":""},"PeriodicalIF":17.1,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149224471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, the extent to which their biodiversity contributes to multifunctionality remains largely unexplored. Here we report data from a large-scale, highly standardized, stratified field survey across 206 European ponds, including 2,500 observations of biodiversity (macrophytes, zooplankton, macroinvertebrates and amphibians) and key ecosystem functions and processes, including methane emissions, litter decomposition, carbon sequestration, primary productivity, biomass accumulation and habitat complexity. Our study reveals a positive and significant association between biodiversity and multifunctionality across multiple taxonomic groups of aquatic organisms, with several ecosystem functions strongly linked to zooplankton richness. The biodiversity-ecosystem multifunctionality relationship tended to be more pronounced in arid regions. By contrast, increasing nutrient concentrations associated with intensive cropland (that is, eutrophication) were negatively related to multiple ecosystem functions, underscoring the importance of pond ecological status in supporting multifunctionality. Taken together, our work provides evidence of the importance of biodiversity in maintaining multifunctionality in small standing freshwater bodies. Preserving and restoring pond habitats by reducing nutrient concentrations will sustain key ecosystem functions in the face of multiple drivers of biodiversity loss.","PeriodicalId":18835,"journal":{"name":"Nature ecology & evolution","volume":" ","pages":""},"PeriodicalIF":17.1,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149183081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing methods span from mechanistic models, whose parameters are difficult to estimate from data, to statistical tools whose context-specific parameters are less interpretable. Here we present a general framework, grounded in the statistical physics of complex systems, that integrates the key processes governing species survival into a single measurable quantity: the competitive balance. This metric quantifies the vulnerability of a focal species to competitive exclusion beyond what is captured by its abundance alone by incorporating the diversity of dispersal strategies and the structure of interspecific interactions within the community. Crucially, the competitive balance can be inferred from spatial abundance data, thus circumventing the need to estimate species traits or dispersal parameters. Our results reveal that greater heterogeneity in dispersal strategies reduces vulnerability to competitive exclusion for a given abundance. We validate the framework using tropical and temperate forest data and discuss how it can be applied to a range of different ecosystems, providing a systemic and interpretable tool for assessing a context-dependent species vulnerability that accounts for its interactions with the entire community.","PeriodicalId":18835,"journal":{"name":"Nature ecology & evolution","volume":" ","pages":""},"PeriodicalIF":17.1,"publicationDate":"2026-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149148858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
