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.
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]
Different animals will manage their circadian rhythm differently, and in some species it's seen to completely stop (such as in European hamsters). Other organisms, such as a black bear, enter torpor and switch to multi-day cycles rather than rely on a circadian rhythm. However, it is seen that both captive and wild bears express similar ...
Hibernation is voluntary, whereas torpor is involuntary, like breathing. There are many animals that do go into full hibernation. True hibernators include squirrels , mice, bats, and turtles .
Well, that’s when rattlesnakes enter a hibernation-like state called “brumation“. During brumation, rattlesnakes seek out a safe place to wait out the winter’s cold.
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]
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 ]
The thirteen-lined ground squirrel (Ictidomys tridecemlineatus), also known as the striped gopher, leopard ground squirrel, and squinny (formerly known as the leopard-spermophile in the age of Audubon), is a species of hibernating ground squirrel that is widely distributed over grasslands and prairies of North America.
