Heart-beat of the Hibernating Hedgehog


THE most characteristic feature of the physiology of hibernation is the changing of a homoiothermic mammal within certain limits into a poikilothermic animal. Thus, for example, the body temperature of the hedgehog may decrease during hibernation to about 2° C. When the animal wakes from hibernation, its body temperature rises in some hours from 2°–5° C. to 30°–35° C. again, and the animal returns to homoiothermy.
