Facts about Hibernation

Hibernation

During hibernation, animals drastically lower their metabolism so as to tap energy reserves stored as body fat at a slower rate.

Hibernation

Hibernation may last several days or weeks depending on species, ambient temperature, and time of the year.

Hibernation

Some scientists see torpor and hibernation as a continuum.

Hibernation

Hibernation can be considered as the most economic choice to escape the extreme environmental conditions.

Hibernation

Some halt their development and remain dormant to escape such situations, including hibernation.

Hibernation

Hibernating animals have something in their blood called HIT, or Hibernation Inducement Trigger.

Hibernation

The energy released in this way is particularly important to rapidly raise the core temperature during waking from hibernation (Taylot et al.

Hibernation

Such a daily torpor differs from hibernation in the length of the dormancy.

Hibernation

Before entering hibernation, most species eat a large amount of food in the fall, while it is plentiful and store energy in fat deposits in order to survive the winter.

Hibernation

Ecologists sometimes prefer to term hibernation as time migration.

Hibernation

Hibernation is a state of inactivity (deep sleep) and metabolic depression in animals, typically in cold weather, and characterized by lower body temperature, slower heart beat and breathing, and lower metabolic rate.

Hibernation

Hibernation helps to conserve energy during winter, when there is scarcity of food.

Hibernation

The major disadvantage of hibernation is that the animal is left quite defenseless if it is not using a very secure, protected hibernating den, (known as the hibernaculum).
