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.
The evolution of endothermy allowed animals to have greater levels of activity and better incubation of embryos, among other benefits for animals in the Permian and Triassic periods. In order to conserve energy, the ancestors of birds and mammals would likely have experienced an early form of torpor or hibernation when they were not using their ...
As winter sets in, colder temperatures force northern alligator lizards to undergo brumation. Brumation allows them to reduce caloric usage and retain body heat during winter. [ 6 ] Often, western alligator lizards choose to hide under rocks—though logs and burrows are occasionally used—to undergo this process.
The blotched blue-tongued lizard usually emerges from brumation in early spring, which is the mating season. These large skinks are viviparous (give birth to live young), with the highland/alpine form giving birth to relatively larger and fewer young (about five) compared to the lowland form (about 11).
S. occidentalis goes through a period of brumation during the winter. The length of time and when they emerge varies depending on climate. During the mating season, adult males will defend a home range. [6] The western fence lizard primarily eats small invertebrates, but may consume any appropriately sized prey item. [11]
Sinaloan milk snakes adapt well in captivity if kept between 80 and 85 degrees Fahrenheit, with a nighttime temperature drop of 5 to 10 degrees. Temperature control is important, as it maintains the animal's feeding response and digestion. Cages should be escape-proof and fresh water provided at all times.
This means that animals like the raccoon can quickly become active again if temperatures rise or the snow melts. [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 ...
