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 chipmunk, for example, is a facultative hibernator. Even though it sleeps for a long period of time, it ...
Aestivation (Latin: aestas (summer); also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, although taking place in the summer rather than the winter. Aestivation is characterized by inactivity and a lowered metabolic rate, that is entered in response to high temperatures and arid conditions. [ 1 ]
Other animals that winter rest are badgers. Although a bear's body temperature decreases less than that of other mammals which undergo true hibernation, mostly changing around 6-7 degrees Celsius, this is a result of their large, heat-retaining body masses. [2] Their metabolism, the main indicator of hibernation, lowers significantly. [3]
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 .
During hibernation, body temperatures usually drop from 37 to 2 °C (99 to 36 °F). Even during their hibernation, they wake up about every two weeks to urinate or eat from their food stashes. Only about 1/3 of all mice that enter hibernation survive; the rest either die from hypothermia or are eaten by predators. Some mice do not enter ...
Wildlife experts say warmer temperatures mean less hibernation and more parasites for hedgehogs.
Some animals seasonally go into long periods of inactivity, with reduced body temperature and metabolism, made up of multiple bouts of torpor. This is known as hibernation if it occurs during winter or aestivation if it occurs during the summer.
In late summer and early fall, groundhogs start chowing down even more vigorously to prepare themselves for hibernation, when a groundhog will lose up to 30 percent of its body weight. By late ...
