Cold-blooded is an informal term for one or more of a group of characteristics that determine an animal's thermophysiology. These include: Ectothermy, controlling body temperature through external processes, such as by basking in the sun; Poikilothermy, the ability of an organism to function over a wide internal temperature range
Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It is most commonly used to pass through winter months – called overwintering.
This species is nocturnal, with a diet of insects, other small animals, fruits and flowers. [12] The fat-tailed lemur is the only known primate to hibernate for extended periods of time, up to seven months. It performs this torpor during the dry season to minimise the impacts of droughts. During the wet season, it gorges on food, accumulating a ...
Black bear mother and cubs hibernating, utilizing a hibernaculum as a maternity den. Like other animals, mammals hibernate during seasons of harsh environmental conditions and resource scarcity. As it requires less energy to maintain homeostasis and survive when an individual is hibernating, this is a cost-effective strategy to increase ...
An animal prepares for hibernation by building up a thick layer of body fat during late summer and autumn that will provide it with energy during the dormant period. During hibernation, the animal undergoes many physiological changes, including decreased heart rate (by as much as 95%) and decreased body temperature . [ 2 ]
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.
For the first time ever, researchers in Europe have spotted an invasive hornet species that is quite large and preys on animals such as butterflies, mantids and even geckos.
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 ]
