Concept explainers
To explain: The alternation of mammalian hibernators between temperature conformity and temperature regulation.
Introduction: Large-bodied animals are capable of physiological adaptations. These adaptations help them to survive in extreme environments such as regional hypothermia, hibernation, and also provide enhanced body insulation.
Explanation of Solution
Hibernation is defined as a state of thermal conformity and low body temperature that persists in winter over a longer time period. During a year’s warm months, the animal acts as a homeotherm and thereby maintains its body temperature close to 37˚C. However, during the year’s cold months, temperature conformity is exhibited by the animals instead of homeothermy. During the conformity stage, the body temperature of the animal matches with the external environment temperature, varying between 0˚C and 10˚C. Thus, the hibernating species alternate between temperature conformity and temperature regulation.
