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 ]
This is true for all clades of animals that undergo winter dormancy; the more prominent the seasons are, the longer the dormant period tends to be on average. Hibernation of endothermic animals has likely evolved multiple times, at least once in mammals—though it is debated whether or not it evolved more than once in mammals—and at least ...
During winter dormancy, plant metabolism comes to a virtual standstill, due in part to low temperatures that slow chemical activity. [1]Dormancy is a period in an organism's life cycle when growth, development, and (in animals) physical activity are temporarily stopped.
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 ...
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.
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.
Some animals seasonally go into long periods of inactivity, with reduced body temperature and metabolism, made up of multiple bouts of torpor. This is known as hibernation if it occurs during winter or aestivation if it occurs during the summer. Daily torpor, on the other hand, is not seasonally dependent and can be an important part of energy ...
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.
