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.
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 ...
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 ]
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.
Diapause in insects is a dynamic process consisting of several distinct phases. While diapause varies considerably from one taxon of insects to another, these phases can be characterized by particular sets of metabolic processes and responsiveness of the insect to certain environmental stimuli. [6]
