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.
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.
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.
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 in nature to hibernation but is different in many ways. Both are dormant-like states that a creature will undergo. For reptiles undergoing brumation, ...
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 ...
Winter rest in an animal is different from true hibernation, since their metabolism is not reduced drastically. Body temperature is not significantly lowered, however their heart rate is reduced. This means that animals like the raccoon can quickly become active again if temperatures rise or the snow melts. [ 1 ]
