ambient environmental temperature. Many terrestrial ectotherms are poikilothermic. However some ectotherms remain in temperature-constant environments...

Melanoplus bivittatus, the two-striped grasshopper, is a poikilothermic species of grasshopper belonging to the genus Melanoplus. It is commonly found...

process, occurring in combination with dehydration. All insects are poikilothermic, so the ability of a few beetles to live in extreme environments depends...

all these criteria. For instance, many bats and small birds become poikilothermic and bradymetabolic during sleep (or, in nocturnal species, during the...

observed in Titanoboa with the climate conditions of its environment. As a poikilothermic ectotherm, Titanoboa's internal temperature and metabolism were heavily...

homeothermy. Heterothermic animals are those that can switch between poikilothermic and homeothermic strategies. These changes in strategies typically occur...

warm-blooded, or endothermic creatures, as opposed to cold-blooded, or poikilothermic animals. However, these words have developed a separate meaning in the...

its relative, the tiger salamander (Ambystoma tigrinum). As for all poikilothermic organisms, lower temperatures result in slower metabolism and a very...

successful recovery. The naked mole rat is the only known mammal that is poikilothermic; it is used in studies on thermoregulation. It is also unusual in not...

the cycle repeats. Most sharks are "cold-blooded" or, more precisely, poikilothermic, meaning that their internal body temperature matches that of their...

nest-guarding behavior. Like all extant non-avian reptiles, they are poikilothermic, and also rely on regular periods of basking under the sun to thermoregulate...

oxygen consumption and ambient temperature switches from a typical poikilothermic pattern to a homeothermic mode when temperature is at 29 °C or higher...

fatty acids. Regulating membrane fluidity is especially important in poikilothermic organisms such as bacteria, fungi, protists, plants, fish and other...

(May 1996). "Comparative aspects of the pineal/melatonin system of poikilothermic vertebrates". Journal of Pineal Research. 20 (4): 175–86. doi:10.1111/j...

like mammals. However, animals with facultative endothermy are often poikilothermic, meaning their temperature can vary considerably. Most fish are ectotherms...

Chromatophores are largely responsible for generating skin and eye colour in poikilothermic animals and are generated in the neural crest during embryonic development...

used for food, the lack of internal temperature control (insects are poikilothermic), high fecundity and rate of maturation. If one treats tofu as a meat...

Early Permian land vertebrates are assumed to have been cold-blooded or poikilothermic, relying on the sun to maintain a high body temperature. Because of...

species, pallid bats are heterothermic, meaning they can be either poikilothermic or homoeothermic depending on the time of year. They have the ability...
