Ecology is a fundamental driving force for the evolutionary transition from solitary living to breeding cooperatively in groups. However, fact that both benign and harsh, as well stable fluctuating, environments can favour evolution of cooperative behaviour constitutes paradox environmental quality sociality. Here, we propose new model - dual benefits framework resolving this paradox. Our distinguishes between two categories grouping resource defence derive group-defended critical resources...
The climatic variability hypothesis posits that the magnitude of increases with latitude, elevation, or both, and greater selects for organisms broader temperature tolerances, enabling them to be geographically widespread. We tested this classical elevational range sizes more than 16,500 terrestrial vertebrates on 180 montane gradients. In support hypothesis, mean size was positively correlated scope seasonal variation, whereas negatively daily variation among accordance a previous life...
Abstract Mountain ranges contain high concentrations of endemic species and are indispensable refugia for lowland that facing anthropogenic climate change 1,2 . Forecasting biodiversity redistribution hinges on assessing whether can track shifting isotherms as the warms 3,4 However, a global analysis velocities isotherm shifts along elevation gradients is hindered by scarcity weather stations in mountainous regions 5 Here we address this issue mapping lapse rate temperature (LRT) across...
Abstract The energy crisis of the 1970s sparked growing concern over minimizing fuel consumption in water, land, and air transportation. Researchers fascinated by sharks' effortless swimming abilities investigated shark skin denticles uncovered functions beyond drag reduction, such as antifouling, protection, bioluminescence. Over past five decades, significant progress has been made comprehending reduction antifouling denticle structures; however, investigation other remains limited. Recent...
Abstract Most marine fish species express life-history changes across temperature gradients, such as faster growth, earlier maturation, and higher mortality at temperature. However, climate-driven effects on life histories population dynamics remain unassessed for most fishes. For 332 Indo-Pacific fishes, we show positive of body growth (but with decreasing asymptotic length), reproductive rates (including age-at-maturation), natural all species, the effect strength varying among...
Abstract Population divergence in geographic isolation is due to a combination of factors. Natural and sexual selection may be important shaping patterns population differentiation, pattern referred as ‘isolation by adaptation’ ( IBA ). can complementary the well‐known distance’ IBD ), which closely related populations (via any evolutionary process) associated with isolation. The barn swallow Hirundo rustica complex comprises six subspecies, where divergent phenotypic differentiation among...
Models of reproductive skew can be classified into two groups: transactional models, in which group members yield shares reproduction to each other return for cooperation, and tug-of-war invest resources a over their respective shares. We synthesize these models “bordered tug-of-war” model the internal is limited (“bordered”) by requirement that must achieve certain amount lest they pursue noncooperative option leading breakup. Previous attempts did not allow fact will affect output, turn...
The ability to form cooperative societies may explain why humans and social insects have come dominate the earth. Here we examine ecological consequences of cooperation by quantifying fitness (large groups) non-cooperative (small phenotypes in burying beetles (Nicrophorus nepalensis) along an elevational temperature gradient. We experimentally created large small groups gradient manipulated interspecific competition with flies heating carcasses. show that performed as thermal generalists...
Cooperatively breeding animals occur in virtually every ecosystem on earth. Comparative and biogeographic studies suggest that both benign harsh-as well as stable fluctuating-environments can favor the evolution of cooperative behavior. The fact societies environments such contrasting quality creates a paradox environmental sociality. dual benefits framework-which leads to prediction ecological consequences sociality (e.g., range size) vary depending individuals each species receive by...
Conflict over reproduction is an inherent part of group living. In many social vertebrates, conflict may be reflected as allostatic load, or the costs status and dominance rank, which quantified by measuring glucocorticoid stress hormones. Here, we develop first quantitative model load based on tug‐of‐war reproductive skew to generate insights into mechanisms underlying in cooperative breeders determine whether glucocorticoids can used assess levels group‐living vertebrates. It predicts that...
Offspring often compete over limited available resources. Such sibling competition may be detrimental to parents both because it entails wasted expenditure and allows stronger offspring obtain a disproportionate share of We studied nestling conflict food its resolution in joint-nesting species bird, the Taiwan yuhina ( Yuhina brunneiceps ). show that adult yuhinas coordinate their feeding visits, this coordination limits among nestlings, leading ‘fairer’ division Transponder identification...
Conflicts of interest over resources or reproduction among individuals in a social group have long been considered to result automatic and universal costs living. However, exploring how conflict varies with size has produced mixed empirical results. Here we develop model that generates alternative predictions for should vary depending on the type benefits gained from being group. We show positive relationship between is favored when groups form primarily sociality but not mainly accessing...
Both benign and harsh environments promote the evolution of sociality. This paradox-societies occur in such contrasting quality-may be explained by different types benefits that individuals receive from grouping: resource defense derive group-defended critical resources versus collective action result social cooperation among group members. Here, we investigate cooperative behavior burying beetle Nicrophorus nepalensis along an elevational gradient where environmental quality (climate...
Abstract Explaining colour variation among animals at broad geographic scales remains challenging. Here we demonstrate how deep learning—a form of artificial intelligence—can reveal subtle but robust patterns feature along an ecological gradient, as well help identify the underlying mechanisms generating this biogeographic pattern. Using over 20,000 images with precise GPS locality information belonging to nearly 2,000 moth species from Taiwan, our learning model generates a 2048-dimension...
Abstract Understanding how phenotypic traits vary among populations inhabiting different environments is critical for predicting a species’ vulnerability to climate change. Yet, little known about the key functional that determine distribution of and main mechanisms—phenotypic plasticity vs. local adaptation—underlying intraspecific trait variation. Using Asian burying beetle Nicrophorus nepalensis , we demonstrate mountain ranges differing in elevation latitude offer unique thermal which...
Deforestation is a major contributor to biodiversity loss, yet the impact of forest loss on daily microclimate variability and its implications for species with different activity patterns remain poorly understood. Using recently developed model, we investigated effects deforestation temperature range (DTR) in low-elevation tropical regions high-elevation temperate regions. Our results show that substantially increases DTR these areas, suggesting potential interactions. To test this...
Bet-hedging-a strategy that reduces fitness variance at the expense of lower mean among different generations-is thought to evolve as a biological adaptation environmental unpredictability. Despite widespread use bet-hedging concept, most theoretical treatments have largely made unrealistic demographic assumptions, such non-overlapping generations and fixed or infinite population sizes. Here, we extend concept consider overlapping by defining with per capita growth rate across environments....

In this study, we assess patterns divergence geographically isolated sympatric subspecies barn swallows (Hirundo rustica), including analyses whether song differentiation varies with geographical isolation, genetic distance climatic distance. We provide first description variation among five six currently recognized swallow subspecies. Temporal traits describing terminal...
