The 44 pages that link to Hibernation, each with the reason it gives.

• ThermoregulationBroader topic: Hibernating animals conserve energy by changing temperature regulation for extended periods.

• SleepCompared with: Unlike nightly sleep, it involves sustained metabolic suppression across seasons.

• EndothermyBroader topic: It shows how endotherms can suspend costly temperature regulation for extended periods.

• TorporCompared with: Torpor is often brief, while hibernation consists of extended bouts interrupted by arousals.

• Animal migrationCompared with: Some animals remain in place through harsh seasons instead of migrating.

• Brown bearRelated: Many brown bears den through winter, relying on stored body fat while eating little or nothing.

• UrsidaeRelated: Some bears enter winter dormancy, relying on stored body fat.

• Brown adipose tissueRelated: Brown fat helps some hibernating mammals rewarm without relying on shivering.

• BrumationCompared with: Its familiar mammalian form differs from the temperature-dependent patterns called brumation.

• Behavioral thermoregulationRelated: Seasonal inactivity can reduce exposure to cold and lower the energy cost of temperature control.

• Crocodilian thermoregulationCompared with: Cold-season crocodilian inactivity is generally tied to local conditions rather than mammalian hibernation.

• HomeothermyBroader topic: Many hibernators suspend homeothermy during deep bouts and restore it during arousals.

• American black bearRelated: In cold regions, black bears spend winter in dens with sharply reduced metabolism.

• DiapauseCompared with: Hibernation is chiefly a physiological winter state, whereas diapause is developmentally regulated.

• SciuridaeRelated: Some marmots and ground squirrels survive winter by sharply reducing activity.

• SquirrelRelated: Some ground squirrels and marmots survive winter through hibernation.

• Ground squirrelRelated: Many ground squirrels survive winter through extended bouts of hibernation.

• RodentiaRelated: Some rodents use hibernation to conserve energy when food and warmth are limited.

• AestivationCompared with: Hibernation is chiefly associated with cold, whereas aestivation is associated with heat or drought.

• Bear (animal)Related: Several bear species spend winter in dens with lowered activity and altered physiology.

• HyperphagiaRelated: Some animals eat heavily before hibernation to build fuel reserves.

• RoostingCompared with: A roost is a resting place; hibernation is a physiological state that may occur within one.

• Butterfly migrationCompared with: Overwintering in place differs from traveling to a separate seasonal region.

• Grizzly bearRelated: Winter denning lets grizzlies survive months when food is limited.

• HeterothermyBroader topic: Its repeated deep cooling and rewarming is a classic temporal form of heterothermy.

• AutumnRelated: Autumn food shortages and cooling temperatures prompt some animals to prepare for hibernation.

• EndothermRelated: Hibernators temporarily suppress the usual high metabolic costs of endothermy.

• Cornu aspersumRelated: Cold-season dormancy lets the snail persist through unfavorable temperatures.

• CryptobiosisCompared with: Metabolism keeps running during hibernation; in cryptobiosis it is undetectable.

• Spectacled bearCompared with: Unlike many bears in cold climates, spectacled bears do not undergo seasonal hibernation.

• Asian black bearRelated: Some populations reduce activity or den through winter when food becomes scarce.

• Cave bearRelated: Cave bear remains accumulated in caves used for winter shelter.

• HelicidaeRelated: Some helicids become inactive in winter, often attached to sheltered surfaces.

• Kodiak bearRelated: Kodiak bears spend winter in dens while relying on stored body fat.

• Wood frogCompared with: Wood frogs remain exposed to freezing rather than avoiding winter through a warm, sheltered refuge.

• GroundhogRelated: Groundhogs endure winter by entering prolonged hibernation in underground dens.

• SpermophilusRelated: Seasonal dormancy is a defining adaptation in many species of Spermophilus.

• BradymetabolismBroader topic: It is a regulated example of profound metabolic slowing.

• Domesticated hedgehogRelated: African pygmy hedgehogs can enter dangerous torpor when their environment becomes too cold.

• ErinaceidaeRelated: Some hedgehogs hibernate when cold and food scarcity make active foraging costly.

• Eurasian brown bearRelated: Many Eurasian brown bears spend winter in dens, although their inactivity is not deep hibernation.

• Helix pomatiaRelated: In cold weather, it withdraws into its shell and seals the opening with an epiphragm.

• Sleep in animalsCompared with: It lasts far longer than typical sleep and includes substantial physiological changes.

• Wood turtleRelated: Wood turtles overwinter underwater, commonly in streambeds.
