As hibernation is a seasonal response, the movement of the ancestor of birds and mammals onto land introduced them to seasonal pressures that would eventually become hibernation. [46] This is true for all clades of animals that undergo winter dormancy; the more prominent the seasons are, the longer the dormant period tends to be on average.
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. Daily torpor, on the other hand, is not seasonally dependent and can be an important part of energy ...
A hibernaculum (plural form: hibernacula) (Latin, "tent for winter quarters") is a place in which an animal seeks refuge, such as a bear using a cave to overwinter.The word can be used to describe a variety of shelters used by many kinds of animals, including insects, toads, lizards, snakes, bats, rodents, and primates of various species.
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. They ...
In warm blooded animals (mammals and birds) this state is referred to as hibernation or torpor (shorter periods of inactivity between awakening); whereas a similar condition in cold-blooded ...
Winter rest (from the German term Winterruhe) is a state of reduced activity of plants and warm-blooded animals living in extratropical regions of the world during the more hostile environmental conditions of winter. In this state, they save energy during cold weather while they have limited access to food sources.
[46] [47] To survive the winter, they are at their maximum weight shortly before entering hibernation. [48] When the groundhog enters hibernation, there is a drop in body temperature to as low as 35 degrees Fahrenheit (2 °C), heart rate falls to 4–10 beats per minute and breathing rate falls to one breath every six minutes. [49]
Snakes across North Carolina hibernate individually in holes in the ground, Hall said. Very few species can make their own holes, so they often find stump holes and rodent burrows to spend much of ...
