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 .
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, heat-retaining body masses. [2] Their metabolism, the main indicator of hibernation, lowers significantly. [3]
Just like humans have homes, animals also have places they live. The places where animals live are called habitats. Also, just as humans are all different and therefore live in different types of ...
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 ...
Aestivation is a behaviour characteristic of water holding frogs. It is similar to how other animals hibernate, except it takes place during summer as opposed to winter when weather conditions are hot and dry. This behaviour is a response to high temperatures and climate extremes of drought.
Aestivation or estivation is the positional arrangement of the parts of a flower within a flower bud before it has opened. Aestivation is also sometimes referred to as praefoliation or prefoliation , but these terms may also mean vernation : the arrangement of leaves within a vegetative bud.
