Hibernation functions to conserve energy when sufficient food is not available. To achieve this energy saving, an endothermic animal decreases its metabolic rate and thereby its body temperature. [3] Hibernation may last days, weeks, or months—depending on the species, ambient temperature, time of year, and the individual's body-condition.
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.

During the first year, the squirrels began hibernation in late October. They started hibernating in mid August and early April respectively for the following two years, displaying a circannual rhythm with a period of about 10 months. [5] An annual rhythm has been observed in humans diagnosed with obsessive compulsive tic disorder (OCTD).
The eastern long-eared bat uses torpor during winter and is able to arouse and forage during warm periods. [25] Some animals use torpor during their reproductive cycle, as seen in unpredictable habitats. [24] They experience the cost of a prolonged reproduction period but the payoff is survival to be able to reproduce at all. [24]
Wildlife experts say warmer temperatures mean less hibernation and more parasites for hedgehogs.
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 ]
In early winter, they increase their subcutaneous fat by 18–23% and their internal fat by 3–5%. Animals failing to reach these fat levels usually do not survive the winter. During their hibernation, their metabolism decreases by 25%. In areas such as Primorsky Krai and their introduced range, common raccoon dogs hibernate only during severe ...
The Arctic ground squirrel hibernates over winter from early August to late April in adult females and from late September to early April for adult males, [15] at which time it can reduce its body temperatures from 37 °C (99 °F) to as little as −3 °C (27 °F). [16] During hibernation, its core body temperature reaches temperatures down to ...
