WebSep 9, 2024 · Torpor, or daily heterothermy, is characterized by facultative hypometabolism and reductions of body temperature ( Tb ), typically by 10–30°C below normothermic values that, unlike hibernation, are restricted to a single circadian cycle [ 14, 15 ]. Torpor is widespread among hummingbirds [ 13, 16 – 19 ], with variation in … Web开馆时间：周一至周日7:00-22:30 周五 7:00-12:00; 我的图书馆

WebJun 19, 2014 · Introduction. Heterothermy in mammals, that is, daily torpor and hibernation, is used by a phylogenetically diverse group of species. Although the phenotype is remarkably variable both within (Wilz and Heldmaier 2000; Gur et al. 2009; Russell et al. 2010; Rojas et al. 2014) and among species (Geiser and Ruf 1995), it is uniformly … WebMay 1, 2014 · Nevertheless, wide fluctuations in daily body temperature, or heterothermy, do occur in large mammals, in situations of water or energy limitation. Indeed, dehydration-induced hyperthermia, an elevation of maximum daily body temperature resulting from suppression of evaporative heat loss, is a well characterized phenomenon in captive … dft of image in python

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. In other words, they exhibit characteristics of both … See more Heterothermic animals are those that can switch between poikilothermic and homeothermic strategies. These changes in strategies typically occur on a daily basis or on an annual basis. More often than not, it is used … See more • Thermobiology of bats See more Regional heterothermy describes organisms that are able to maintain different temperature "zones" in different regions of the body. This usually occurs in the limbs, and is … See more • Mesotherm • Poikilotherm See more Webimportant if we are to understand the evolution of daily heterothermy and hibernation in mammals.
