Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It is most commonly used to pass through winter months – called overwintering.
The production of heat by brown fat metabolism is called non-shivering thermogenesis and is common in many hibernating animals. ... roles in winter survival. Animals that remain somewhat active ...
Winter rest (from the German term Winterruhe) is a state of reduced activity of plants and warm-blooded animals living in extratropical regions of the world during the more hostile environmental conditions of winter. In this state, they save energy during cold weather while they have limited access to food sources.
Wildlife experts say warmer temperatures mean less hibernation and more parasites for hedgehogs.
Some animals seasonally go into long periods of inactivity, with reduced body temperature and metabolism, made up of multiple bouts of torpor. This is known as hibernation if it occurs during winter or aestivation if it occurs during the summer. Daily torpor, on the other hand, is not seasonally dependent and can be an important part of energy ...
Snakes across North Carolina hibernate individually in holes in the ground, Hall said. Very few species can make their own holes, so they often find stump holes and rodent burrows to spend much of ...
However, when animals live in an environment that is inhospitable for much of the year, then hibernation is not necessary. One of the few animals that does so are lemmings, which have a mass migration after they come out of dormancy. However, most animals living in the arctic would still be active, even during the most brutal times of winter.
All animals remain on-site throughout the year in their various homes. Jasmine, a snow leopard, alternates between indoor and outdoor areas along with Raj, the zoo's male snow leopard at Binder ...
