Temperatures Respiration below freezing have been measured in some hiber- nating bats. Also, the heart and breathing rates drop significantly. These will only be strong enough to keep the animal alive, though the heart rate can increase slightly if outside temperatures become too cold. Stored fat will power the hibernating animal at "idle speed" until the spring. GE
