The skin is grey with scanty hairs, and bending cracks which support thermoregulation by retaining water. The African bush elephant inhabits a variety of habitats such as forests, grasslands, woodlands, wetlands and agricultural land. It is a mixed herbivore feeding mostly on grasses, creepers, herbs, leaves, and bark. The average adult ...
When the body temperature is too high or too low, the blood vessels will change size accordingly to bring the body’s temperature back to normal. In this diagram, the tube-shaped objects represent blood vessels and the red and blue objects represent thermometers. The middle blood vessel is sized for a blood vessel at normal body temperature.
Heterothermy or heterothermia (from Greek ἕτερος heteros "other" and θέρμη thermē "heat") is a physiological term for animals that vary between self-regulating their body temperature, and allowing the surrounding environment to affect it.
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 ...

On the other side, the mechanisms for thermoregulation did not evolve separately, but rather in connection with other functions. [19] These mechanisms were more likely quantitative rather than qualitative and it involved selection of appropriate habitats, changes in levels of locomotor activity, optimum energy liberation, and conservation of ...
The honey bee, for example, does so by contracting antagonistic flight muscles without moving its wings (see insect thermoregulation). [ 18 ] [ 19 ] [ 20 ] This form of thermogenesis is, however, only efficient above a certain temperature threshold, and below about 9–14 °C (48–57 °F), the honey bee reverts to ectothermy.
The metabolic theory of ecology (MTE) [1] is the ecological component of the more general Metabolic Scaling Theory [2] and Kleiber's law.It posits that the metabolic rate of organisms is the fundamental biological rate that governs most observed patterns in ecology.
