Other animals that winter rest are badgers. Although a bear's body temperature decreases less than that of other mammals which undergo true hibernation, mostly changing around 6-7 degrees Celsius, this is a result of their large, heat-retaining body masses. [2] Their metabolism, the main indicator of hibernation, lowers significantly. [3]
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.
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.
During hibernation, body temperatures usually drop from 37 to 2 °C (99 to 36 °F). Even during their hibernation, they wake up about every two weeks to urinate or eat from their food stashes. Only about 1/3 of all mice that enter hibernation survive; the rest either die from hypothermia or are eaten by predators. Some mice do not enter ...
A fecal plug (sometimes referred to as a tappen) is a significant biological phenomenon observed in bears and other animals during hibernation.It is a dense mass of hardened feces that forms in the colon due to having remained in the intestine so long that the intestinal walls have absorbed the fluids out of it, leaving it dry and hard.

Aestivation (Latin: aestas (summer); also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, although taking place in the summer rather than the winter. Aestivation is characterized by inactivity and a lowered metabolic rate, that is entered in response to high temperatures and arid conditions. [ 1 ]
An animal prepares for hibernation by building up a thick layer of body fat during late summer and autumn that will provide it with energy during the dormant period. During hibernation, the animal undergoes many physiological changes, including decreased heart rate (by as much as 95%) and decreased body temperature . [ 2 ]
Hibernation lasts until about mid April to May, with males emerging slightly earlier than females. From the time that the meadow jumping mouse goes into hibernation to the time it comes out there is a significant amount of weight loss. When the male emerges from hibernation it starts feeding and is immediately reproductively active.
