Larger antelopes are sensitive to heat stress throughout all seasons but smaller antelopes only during summer in an African semi-arid environment
Heat stress can limit the activity time budget of ungulates due to hyperthermia, which is relevant for African antelopes in ecosystems where temperature routinely increases above 40 °C. Body sizeExpand

Body temperature variation of South African antelopes in two climatically contrasting environments
Abstract To understand the adaptive capacity of a species in response to rapid habitat destruction and climate change, we investigated variation in body temperature (Tb) of three species of antelope,Expand

Energy advantages of orientation to solar radiation in three African ruminants
Animal orientation relative to incident solar radiation allows an animal to effectively adjust the amount of radiant heat gained from an environment. Yet recent literature found ruminants toExpand

Effects of desertification on the body temperature, activity and water turnover of Angora goats
Abstract Globally, pastoral practices have transformed habitats, which often lead to desertification. With climate change predicted to exacerbate desertification, adaptation provides the bestExpand

Efficacy of Different Cooling Methods for Capture-Induced Hyperthermia in Antelope
The capture of wild animals is a stressful event which may cause a capture-induced hyperthermia, resulting in morbidity or mortality. We investigated whether various cooling techniques were effectiveExpand

Consequences of sex-specific sociability for thermoregulation in male vervet monkeys during winter
While most primates are tropical animals, a number of species experience markedly cold winters. In a high latitude arid environment, wild female vervet monkeys (Chlorocebus pygerythrus) that areExpand

Ecological niche separation of two sympatric insectivorous lizard species in the Namib Desert
Abstract Individual lizard species may reduce competition within a habitat by diverging along one or more niche dimensions, such as spatial, temporal or dietary dimensions. We compared theExpand

Stable isotope analysis of diet confirms niche separation of two sympatric species of Namib Desert lizard.
We used stable isotopes of carbon and nitrogen to study the trophic niche of two species of insectivorous lizards, the Husab sand lizard Pedioplanis husabensis and Bradfield's Namib day gecko livingExpand

Cheetahs discriminate familiar and unfamiliar human voices
Domestic species can make the distinction between several human sub-groups, especially between familiar and unfamiliar persons. The Domestication hypothesis assumes that such advanced cognitiveExpand
