Hibernation is a mechanism used by many mammals to reduce energy expenditure and survive food shortages over the winter. Hibernation may be predictive or consequential. 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.
Facultative hibernators enter hibernation only when either cold-stressed, food-deprived, or both, unlike obligate hibernators, who enter hibernation based on seasonal timing cues rather than as a response to stressors from the environment. A good example of the differences between these two types of hibernation can be seen in prairie dogs.
Many reptiles undergo hibernation or a process called brumation, which is similar to hibernation; both processes require usage of a hibernaculum. Staying inside an insulated hibernaculum is a strategy to avoid the harsh winter months when the frigid outside temperatures may kill an ectothermic reptile.
Hibernation vs. brumation. Hibernation and brumation are both natural responses to cold temperatures in animals, but they differ in key aspects. While hibernation is a state of prolonged dormancy ...
Brumation is similar to hibernation, but also is different in many ways. Both are dormant-like states that an animal will undergo. For reptiles undergoing brumation, during this time, the creature ...

When the temperatures begin to drop, snakes go into a state called brumation. This event acts as a type of hibernation for cold-blooded animals. This event acts as a type of hibernation for cold ...
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 ]
