Adaptation to Heat
In hot regions, survival and prosperity of animals depend to a large extent on water: indirectly because precipitation determines the availability of vegetable food, and directly because water is needed for evaporative cooling. Indigenous species have developed behavioural and physiological adaptations to survive on limited food resources and to confine the dependence on evaporative cooling. Again, success of a certain adaptive strategy is linked to body mass, and humans receive separate treatment because their heat adaptation has been studied more intensively than that of any other species.
