We used a translocation experiment in southern and central Europe to unravel the short-term effects of macroclimatic (elevation and latitude) and microclimatic conditions (open vs. dense forests, forest edge vs. core position) on plant survival, flowering and traits in eight understorey specialists. Forest density was the main driver of survival, with positive effects in the warm and water-limited southern region and negative effects in the northern oceanic region. Forest position had weaker effects, influencing survival, growth and SLA in contrasting ways at the two latitudes. Most species flowered beyond their northern limit, suggesting the ability for reproduction at higher latitudes. Macroclimate effects on forest herbs interact with forest density, influencing their performance and suggesting complex responses to climate change. Increased vulnerability is expected in relatively open and warmer forests.","PeriodicalId":161,"journal":{"name":"Ecology Letters","volume":"28 8","pages":""},"PeriodicalIF":7.9,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ele.70184","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144767335","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}

While typically observed at the organismal level, it can also occur at higher levels of biological organisation. Polydnaviruses represent a striking example of convergent evolution. These viruses, divided into bracoviruses and ichnoviruses, were independently acquired by braconid and ichneumonid parasitoid wasps respectively, to deliver pathogenic genes to caterpillar hosts. Here we show convergent patterns across trophic levels, demonstrating that both bracoviruses and ichnoviruses induce changes in plant-phenotypic traits that specifically benefit their parasitoid partners, facilitating plant-mediated host discrimination. This is achieved through an interaction network triggered by changes in the polydnavirus-infected herbivore (via alteration in regurgitant composition) which eventually affected parasitoids' foraging decisions. Our findings unveil a novel ecological benefit that polydnaviruses offer to their parasitoid partners through intricate, plant-mediated effects, providing evidence of convergence in symbiont-induced responses in terrestrial trophic systems.","PeriodicalId":161,"journal":{"name":"Ecology Letters","volume":"28 8","pages":""},"PeriodicalIF":7.9,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ele.70183","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144751344","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, projecting its impact on multispecies coexistence remains a challenge. Here, we conducted pairwise experiments with five native and five non-native species, using the Ricker model to estimate interaction coefficients and population growth rates. We assessed the impact of non-native species on community persistence potential through a structural approach that integrates multispecies interactions and estimates coexistence probabilities. We found that community persistence potential generally declined after invasion, with the feasibility domain (i.e., the probability that all species co-occur simultaneously) becoming more asymmetric as more native species were replaced by non-native ones. Interestingly, non-native species were more likely to be excluded first under random environmental perturbations in communities where they were dominant. Our findings highlight the importance of clarifying species interaction structure under random disturbances in shaping community persistence and suggest tailored invasion management strategies to optimise resource allocation.","PeriodicalId":161,"journal":{"name":"Ecology Letters","volume":"31 1","pages":"e70154"},"PeriodicalIF":8.8,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144791902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While collections data are key components of eco-evolutionary and environmental research in both fundamental and applied contexts, collecting strategies remain primarily taxonomically motivated. We argue that sampling strategies must evolve to better address broader ecological challenges, through emerging applications enabled by advances in data science and digital technology. Here, we propose a flexible framework using modern statistical approaches to optimise sampling design and research prioritisation. By considering biodiversity, environmental, spatial and temporal dimensions, we demonstrate how information theory and decision science tools can support strategic collecting, databasing and digitisation efforts. Our framework provides an evidence-based pathway for collections to enhance their role as critical research infrastructure for addressing 21st century environmental challenges. To illustrate this data-driven approach to research prioritisation, we present an example based on sampling design for wombats (Vombatus ursinus) in Australia.","PeriodicalId":161,"journal":{"name":"Ecology Letters","volume":"28 8","pages":""},"PeriodicalIF":7.9,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ele.70188","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144751345","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}

Yet, we lack field experiments testing this fundamental relationship and its underlying mechanisms in naturally assembled multitrophic systems. To address this gap, we monitored experimental substrates replicating topographic heterogeneity on a rocky shore over 3 years. Contrary to theory, heterogeneity showed no net effect on community stability due to four counteracting pathways. Heterogeneity increased stability by (i) providing refugia that enhanced population stability and (ii) boosting species richness, which promoted asynchrony. At the same time, it decreased stability by (iii) reducing a dominant non-native species and (iv) suppressing consumers, both of which otherwise stabilised community composition. These opposing processes cancelled out the heterogeneity–stability relationship, highlighting the complex and multi-causal nature of this relationship. We caution against the assumption that increasing heterogeneity universally enhances stability, particularly in systems with strong consumer interactions and dominant species.","PeriodicalId":161,"journal":{"name":"Ecology Letters","volume":"28 8","pages":""},"PeriodicalIF":7.9,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ele.70158","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144751346","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}

Urban systems present a unique opportunity to evaluate how environmental change shapes variation since urban phenotypic differentiation is widely documented on contemporary timescales. We introduce and test three hypotheses to determine how urbanisation affects phenotypic variation at different population levels. Combining 21 long-term datasets in a mega-analysis approach, we synthesise how urbanisation impacts variation in tarsus length and lay date among and within subpopulations of great and blue tits (Parus major, Cyanistes caeruleus ) at a continental scale. Our synthesis reveals that urbanisation is associated with increased phenotypic variation within subpopulations by 11% on average, and by as much as 25% across the species and traits examined. We also find some evidence (for tarsus length in great tits) that urbanisation increases differentiation between subpopulations. We did not, however, find that urbanisation increases differences between subpopulations in their within-subpopulation variation. Our synthesis provides novel insights into how urban contexts impact individual diversity at different spatial scales and we highlight future directions that could establish the genetic and environmental effects that underlie these continental patterns of urban phenotypic variation.","PeriodicalId":161,"journal":{"name":"Ecology Letters","volume":"28 7","pages":""},"PeriodicalIF":7.6,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ele.70180","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144688078","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}
