Torpor: what it is, why it's important and how torpor differs ...
Nov 17, 2021 · Torpor is a hypothermic, hypometabolic, adaptive response, engaged by a range of animals in order to reduce metabolic demand. Torpor can be brief, in daily heterotherms such as the mouse, or it can be prolonged, in seasonal hibernators.

Both the minimum temperature achieved and the duration of torpor are highly variable. Daily torpor is principally a response to reduced energy intake, and a drop in ambient temperature. Hibernation is essentially an extreme form of torpor.
Definition. Torpor is a state of decreased physiological activity in animals, characterized by reduced metabolism, body temperature, and physiological functions. It allows animals to conserve energy during periods of limited food availability or harsh environmental conditions.
Nov 21, 2019 · Torpor is a period of “decreased physiological activity” such as reducing their body temperature and metabolism. Birds undergo torpor as well as marsupial mammals like our opossums, bats, skunks, and rodents. Sometimes torpor occurs at night after a day of looking for food.

For example, the Arctic ground squirrel (whose winter period of dormancy is referred to as hibernation), when taken into the laboratory, supplied with adequate amounts of food and water, and exposed to constant temperature and light, exhibits periodic torpor (extreme sluggishness)—an innate behavioral pattern that operates independently of ...
