Thermoregulatory mechanisms of endotherms
Webbnize the thermoregulatory mechanisms that are implicated in the aging process in endotherms and ectotherms. We hope that this comparative approach will aid our understanding of aging and longevity and will contribute toward future advancements that could compress morbidity and lower disease and mortality risk. Aging, Physiology, and … Webb10 okt. 2016 · Increases in T b reduces both the energetic and water costs of cooling mechanisms [32, 34, 35]. Variable T b is widespread in mammals, and both habitat and evolutionary history have a large influence on the thermoregulatory characteristics of endotherms [10, 29, 36].
