Webb15 okt. 2010 · Small endotherms especially are challenged by life in the cold (Humphries 2005), particularly if they remain active during winter rather than using torpor as an energy-conservation strategy. Some small endotherms have a lower body temperature (T b ) and thicker fur in winter, reducing the ingested energy required to maintain T b compared to … WebbPoikilotherms are animals that do not require a fixed body temperature, their temperatures can fluctuate with little to no adverse effects to their overall health. Most terrestrial …
