Such organisms (frogs, for example) rely on environmental heat sources, [3] which permit them to operate at very economical metabolic rates. [ 4 ] Some of these animals live in environments where temperatures are practically constant, as is typical of regions of the abyssal ocean and hence can be regarded as homeothermic ectotherms.
Another example would be the case of the fairy prion (Pachyptila turtur) that forms a close association with a medium-sized reptile, the tuatara (Sphenodon punctatus). [16] These reptiles share the burrows made by the birds, and often stay when the birds are present which helps maintain a higher body temperature. [ 16 ]
The pre-flight warm-up behavior of a moth. Insect thermoregulation is the process whereby insects maintain body temperatures within certain boundaries.Insects have traditionally been considered as poikilotherms (animals in which body temperature is variable and dependent on ambient temperature) as opposed to being homeothermic (animals that maintain a stable internal body temperature ...
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.
A eurytherm is an organism, often an endotherm, that can function at a wide range of ambient temperatures. [1] To be considered a eurytherm, all stages of an organism's life cycle must be considered, including juvenile and larval stages. [2]
His work also explored the adaptive patterns in behavior and energy allocation of ectothermic vertebrates, [14] particularly reptiles, [15] [16] which have limited oxygen uptake and rely on anaerobic metabolism for intense activity. In a highly cited 1979 joint research work with J. Ruben, he compared aerobic metabolism between endothermic and ...
The mouse is endothermic and regulates its body temperature through homeostasis. The lizard is ectothermic and its body temperature is dependent on the environment. Many endotherms have a larger amount of mitochondria per cell than ectotherms. This enables them to generate heat by increasing the rate at which they metabolize fats and sugars ...
Thermogenesis is the process of heat production in organisms.It occurs in all warm-blooded animals, and also in a few species of thermogenic plants such as the Eastern skunk cabbage, the Voodoo lily (Sauromatum venosum), and the giant water lilies of the genus Victoria.
