Abstract Theory predicts that risk taking should be influenced by external (eg, season) and
internal (eg, breeding condition, sex, and body mass) conditions. We investigated whether …

on the surface, where courtship occurs, is limited by high temperatures.•Male fiddler crabs …

Although consistent between‐individual differences in behaviour (ie animal personality) are
ubiquitous in natural populations, relatively few studies have examined how personalities …

Multiple mating by avian females may increase hatching and overall brood success;
however, reproductive effort and parental investment are costly, and females may be …

Conspecific individuals often consistently differ in their behavioral responses to specific
exogenous stimuli. Such individual differences in “personality” have been shown to be …

In wild vertebrates, conspicuousness often signals a high phenotypic quality and is therefore
associated with fitness benefits (“the handicap principle hypothesis”). However, conspicuous …

Biological invasion is a global problem with large negative impacts on ecosystems and
human societies. When a species is introduced, individuals will first have to pass through the …

We observed a colony of Village Weavers Ploceus cucullatus in Ethiopia at the height of the
breeding season to assess variation and relationships amongst male behaviours …

Roads affect wildlife in a variety of negative ways. Road ecology studies have mostly
concentrated on areas in the northern hemisphere despite the potentially greater impact of …

Behavioural responses are particularly important to quantify species-specific habitat
influences on natural selection. Mountains, with their wide range of habitats, can be …
