Hibernation
|
1.) A state of dormancy or reduced activity typically entered at the onset of winter. Hibernating saves the animal a great deal of energy at a time where food is not readily available. Also referred to as 'overwintering.'2.) A dormant, sleeplike state, with a lower body temperature and slower heart and breathing rate, that is characteristic of various animals during the winter months in cold climates, such as bears, bats, certain birds, snakes, frogs, and turtles; this state tends to protect against cold weather and to reduce the need for food (Morris 1992). Ground squirrels are good examples of hibernating mammals as some hibernate for about 9 months. Hibernators do arouse from hibernation periodically, but usually stay in their hibernation chamber or nest. |
