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.
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.
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 ...
Insect winter ecology describes the overwinter survival strategies of insects, which are in many respects more similar to those of plants than to many other animals, such as mammals and birds. Unlike those animals, which can generate their own heat internally ( endothermic ), insects must rely on external sources to provide their heat ...
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.
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 ...
Common examples include cross-country skiing, Alpine skiing, snowboarding, snowshoeing, and snowmobiling. The design of the equipment used, e.g. skis and snowboards, typically relies on the bearing strength of snow and contends with the coefficient of friction bearing on snow. Skiing is by far the largest form of winter recreation.
