Anthropogenic climate change is increasing the frequency and intensity of heat waves, thereby threatening biodiversity, particularly in hot, arid regions. Although free-ranging endotherms can use behavioral thermoregulation to contend with heat, it r

Global warming and intensifying extreme heat events may affect avian reproductive success and costs, particularly in hot, arid environments. It is unclear how breeding birds alter their behaviour in response to rapid climate change, and whether such

Rising temperatures pose a grave risk to arid zone birds because they are already living close to their physiological limits and must balance water conservation against the need for evaporative cooling. We assess how extreme temperatures affect a wil

Individual specificity can be found in the vocalizations of many avian and mammalian species. However, it is often difficult to determine whether these vocal cues to identity rise from “unselected” individual differences in vocal morphology or wh

Social complexity and communicative complexity appear to have coevolved in terrestrial vertebrates. Understanding the information conveyed within the social signals of group-living taxa can illuminate the selection pressures impacting on a species an

Intense intrasexual competition for breeding opportunities is a characteristic of cooperatively breeding species with high reproductive skew. In such ‘singular’ cooperative breeders, females suffer greater variability in direct reproductive succe

Scent marking is an important means of communication in mammals and many species elevate their scent marks by depositing them on vertical objects. Traditionally, it has been assumed that marks are elevated to increase detectability, but elevated mark

Many of the mechanisms advanced to explain the evolution of intraspecific cooperative behaviour, such as reciprocity or social prestige, hinge on an animal's ability to recognize individual group members. However, ‘true’ individual recognition, b

Many mammal species adopt marking postures that elevate their scent deposits. The most extreme of these is handstand marking, in which an individual reverses against an upright object, flings its hind legs into the air above its back and balances bip
