Despite being ectotherms, reptiles have an ability to thermoregulate which is enhanced by adopting a variety of behavioural mechanisms. Different behavioural postures, the use of retreat sites and selection of microhabitats enable reptiles to maintain their core body temperatures (T b ) above that of ambient temperatures (T a ) in winter or below T a maximum in summer. This...
Since Black-tailed Tree Rats, Thallomys nigricauda, face variable thermal environments in their extensive range in southern Africa, variation in their physiological and behavioural responses to the wide range of ambient temperatures (T a s) was expected to play a role in the success and range of the species. Body temperature (T b ) and activity patterns of free-ranging Tree Rats were...
