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 ]
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 ...
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.
Seasonally polyestrous animals or seasonal breeders have more than one estrous cycle during a specific time of the year and can be divided into short-day and long-day breeders: Short-day breeders, such as sheep, goats, deer and elk are sexually active in fall or winter.
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 ...
Overwintering is the process by which some organisms pass through or wait out the winter season, or pass through that period of the year when "winter" conditions (cold or sub-zero temperatures, ice, snow, limited food supplies) make normal activity or even survival difficult or near impossible. In some cases "winter" is characterized not ...
Another example would be the case of the fairy prion (Pachyptila turtur) that forms a close association with a medium-sized reptile, the tuatara (Sphenodon punctatus). [16] These reptiles share the burrows made by the birds, and often stay when the birds are present which helps maintain a higher body temperature. [ 16 ]
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]
