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.
A hibernation factor is a protein used by cells to induce a dormant state by slowing or halting the cellular metabolism. [1] This can occur during periods of stress, [ 1 ] randomly in order to allocate "designated survivors" in a population, [ 1 ] or when bacteria cease growth (enter stationary phase ). [ 2 ]
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.
Hibernation is a handy biological tool. If you can’t snowbird somewhere warmer in the winter, it’s best just to hunker down, conserve energy, and wait for the spring when resources are more ...
Anhydrobiosis in the tardigrade Richtersius coronifer. Anhydrobiosis is the most studied form of cryptobiosis and occurs in situations of extreme desiccation.The term anhydrobiosis derives from the Greek for "life without water" and is most commonly used for the desiccation tolerance observed in certain invertebrate animals such as bdelloid rotifers, tardigrades, brine shrimp, nematodes, and ...
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 .
At least six major areas of cryobiology can be identified: 1) study of cold-adaptation of microorganisms, plants (cold hardiness), and animals, both invertebrates and vertebrates (including hibernation), 2) cryopreservation of cells, tissues, gametes, and embryos of animal and human origin for (medical) purposes of long-term storage by cooling to temperatures below the freezing point of water.
