According to behavioural ecology theory, sociality evolves when the net benefits of close
association with conspecifics exceed the costs. The nature and relative magnitude of the …

Species that respond to ecosystem change in a timely, measurable, and interpretable way
can be used as sentinels of global change. Contrary to a pervasive view, we suggest that …

Recent mass mortalities of bats, birds and even humans highlight the substantial threats that
rising global temperatures pose for endotherms. Although less dramatic, sublethal fitness …

Nest or roost temperature (T roost) is thought to impact reproductive fitness in many
endotherms but few studies have directly tested the hypothesis that naturally occurring …

Aim Climate and land‐use change, the greatest pressures on biodiversity, can directly
influence each other. One key case is the impact land‐use change has on local climatic …

An improved understanding of life-history responses to current environmental variability is
required to predict species-specific responses to anthopogenic climate change. Previous …

Cooperative behavior is a hallmark of the primate order. Cooperation is therefore an area of
intensive theoretical research in biology, anthropology, political sciences and economics, as …

Allee effects have important implications for many aspects of basic and applied ecology. The
benefits of aggregation of conspecific individuals are central to Allee effects, which have led …

Species in extreme habitats increasingly face changes in seasonal climate, but the
demographic mechanisms through which these changes affect population persistence …

Despite the prevalence of vocal mimicry in animals, few functions for this behaviour have
been shown. I propose a novel hypothesis that false mimicked alarm calls could be used …
