What physiological adaptations help bandicoots survive in Australia’s hot and dry climates?
Answer
Low body temperature and a low basal metabolic rate.
To cope successfully with the often challenging environmental conditions found in Australia, characterized by heat and dryness, bandicoots have evolved specific internal physiological mechanisms. A key aspect of this adaptation is maintaining a low body temperature coupled with a low basal metabolic rate (BMR). By keeping their internal energy expenditure and core temperature lower than many other active mammals, they reduce the physiological stress associated with heat load and minimize the water loss associated with higher metabolic processes, allowing them to persist in resource-scarce environments.
