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 ]
Aestivation, also spelled estivation, is an example of consequential dormancy in response to very hot or dry conditions. It is common in invertebrates such as the garden snail and worm but also occurs in other animals such as lungfish, salamanders, desert tortoises, and crocodiles.
Even though it sleeps for a long period of time, it is not a true obligate hibernator. This is because during the long period of sleep, its temperatures do not decrease to the low levels of hibernation. It only truly hibernates if food is scarce. [15] A good example of the differences between these two types of hibernation can be seen in ...
All animals remain on-site throughout the year in their various homes. Jasmine, a snow leopard, alternates between indoor and outdoor areas along with Raj, the zoo's male snow leopard at Binder ...
Migration is a common effect of winter upon animals such as migratory birds. Some butterflies also migrate seasonally. Hibernation is a state of reduced metabolic activity during the winter. Some animals "sleep" during winter and only come out when the warm weather returns; e.g., gophers, frogs, snakes, and bats.
Some of the park's African animals, such as white rhinos and yellow mongooses, were born and raised on site rather than in warmer climes so are more used to British winters. The park said all of ...
The eastern long-eared bat uses torpor during winter and is able to arouse and forage during warm periods. [25] Some animals use torpor during their reproductive cycle, as seen in unpredictable habitats. [24] They experience the cost of a prolonged reproduction period but the payoff is survival to be able to reproduce at all. [24]
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.
