Webb4 okt. 2016 · In outlining social thermoregulation as a crucial feature of the human essence, we focus on the continuity of thermoregulatory mechanisms from other animals to humans. We then provide a number of different effects from the social psychological literature that helps us understand how thermoregulation is implicated in social behavior.
WebbThe average energy cost of thermoregulation (C th) for adult penguins was equivalent to 10–16% of basal metabolism. C th comprised about 15% of the estimated daily energy budget (DEB) of incubating adults, but only about 1% of the DEB of adults feeding chicks. The T e 's for chicks older than 14 days ranged from 0 to 31°C, averaging 8.0 C.
