Overall, we found a significant positive residual correlation between innovation rate and collision incidence, independent of ecological covariates and phylogenetic relationships. However, this relationship was hazard-specific: innovativeness positively correlated with building collisions but showed no relationship with communication towers or wind turbines. Furthermore, collision risk was driven by food-related rather than technical innovations. Rather than demonstrating a universal mortality cost of cognitive capacity, our results suggest that opportunistic foraging behaviours may create ecological traps in structurally dense environments. Ultimately, behavioural plasticity can drive fitness consequences, but this risk is fundamentally context-dependent.</p>\u0000 </div>","PeriodicalId":161,"journal":{"name":"Ecology Letters","volume":"29 4","pages":""},"PeriodicalIF":7.9,"publicationDate":"2026-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147615498","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 ALAN drives population declines in insects and reptiles, birds defy simple patterns. Avian responses to ALAN vary in direction and magnitude, yet the fitness consequences of these responses remain unresolved. We conducted a meta-analysis to test whether ALAN alters avian physiology, behaviour and life-histories, analysing 675 effect sizes from 36 studies across 30 species. We found consistent physiological and behavioural shifts under ALAN, while life-history traits were unaffected. ALAN disrupted physiology through reduced sleep, higher metabolic rate and accelerated reproductive maturation. Behaviourally, daily activity was extended, with earlier onset, later offset, and increased nocturnal activity and foraging effort. Subset analyses revealed stronger ALAN effects in migratory species compared to residents and more pronounced in adults and females than in nestlings and males. Activity shifts, accelerated ageing and sleep disruption were amplified with brighter light. Birds appeared to buffer ALAN effects through physiological and behavioural adjustments, minimising impacts on life-histories, a paradox likely explained by phenotypic plasticity or evolutionary adaptation.

Environmental conditions are thought to play a crucial role, as long-lived species are predicted to favour more precautionary life-history strategies in variable environments. However, empirical evidence remains limited. Using long-term monitoring of two black-browed albatross Thalassarche melanophris populations, we investigated variation in life-history strategies under contrasting environmental conditions, through reproductive senescence. In more variable environments, individuals displayed generally slower life histories (i.e., slow, late-onset senescence) and greater among-individual variation in life-history strategies. Interestingly, earlier and faster reproductive senescence correlated with higher lifetime reproductive success regardless of environmental variability, suggesting that either faster life histories incur higher fitness or successful reproduction accelerates reproductive senescence. These findings reveal how environmental variability shapes life-history strategies, highlighting potential responses to increasing environmental variability in a changing world.","PeriodicalId":161,"journal":{"name":"Ecology Letters","volume":"23 1","pages":"e70384"},"PeriodicalIF":8.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147695227","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}

However, it is unclear how traits shaped by sexual selection affect population dynamics and recovery. We examined this by manipulating presence/absence of males expressing either a non-aggressive 'scrambler' phenotype or an aggressive and lethally armed 'fighter' phenotype in soil mite populations of different size. We experimentally altered the male phenotype in populations, subjected them to heat stress, and analysed their population dynamics and recovery. We show that populations with fighter males exhibited (i) reduced population size and stability, (ii) greater decline in response to heat stress in larger populations, (iii) higher rate of growth and (iv) incomplete population recovery. Such reduced population stability and recovery linked with armed and aggressive phenotypes underlines the importance of sexual selection in mediating population dynamics and resilience to environmental change with implications for managing natural populations.","PeriodicalId":161,"journal":{"name":"Ecology Letters","volume":"10 1","pages":"e70377"},"PeriodicalIF":8.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147702137","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}

Despite the storage effect's prominence in theoretical ecology, we lack evidence on whether it maintains biodiversity in nature. Here, we examine five storage effect pathways in a community of 11 coral species from the Great Barrier Reef, using detailed size-structured demographic data collected over 5 years. We parameterize integral projection models, simulate coral communities, and quantify coexistence mechanisms through Modern Coexistence Theory. Fluctuations in survival and fecundity promote coexistence via the storage effect, but this stabilising mechanism is typically small compared to fitness differences. Despite exhibiting prerequisites for strong temporal niche partitioning, the storage effect cannot explain the coexistence of many species. Diversity maintenance likely requires large net contributions from other mechanisms, such as specialist natural enemies or spatial heterogeneity coupled with source-sink dynamics.","PeriodicalId":161,"journal":{"name":"Ecology Letters","volume":"51 1","pages":"e70362"},"PeriodicalIF":8.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147702138","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}

In passive dispersers, for whom only departure timing is under control, the mechanisms of take-off remain poorly understood. Using experimental evolution, we tested how niche breadth modulates passive dispersal in phytophagous mites by exposing specialist and generalist lineages to host-derived kairomones. Dispersal was highly context-dependent. Generalists exhibited higher baseline dispersal and increased take-off when detecting familiar target cues; however, they were inhibited by complex mixtures of unfamiliar cues (low signal-to-noise ratio). Conversely, specialists primarily tracked current host quality, departing significantly more frequently from unfamiliar plants, yet showing little modulation by target cue identity. These results demonstrate that divergent host specialisation in homogeneous versus heterogeneous environments fundamentally alters the way in which organisms integrate information from current and future habitats to drive dispersal. Niche breadth dictates the baseline propensity for informed departure, while olfactory context provides the final trigger for passive take-off.</p>","PeriodicalId":161,"journal":{"name":"Ecology Letters","volume":"29 4","pages":""},"PeriodicalIF":7.9,"publicationDate":"2026-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ele.70373","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147584143","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}
