Thermoregulation penguins
Webb5 sep. 2015 · Thermoregulation is the maintenance of a relatively constant core body temperature. Humans normally maintain a body temperature at 37°C, and maintenance of this relatively high temperature is critical to human survival.

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. WebbThermoregulation is the ability of an organism to keep its body temperature within certain boundaries, ... (such as the mousebird and emperor penguin) it allows the sharing of body heat (particularly amongst juveniles). This allows the individuals to increase their thermal inertia (as with gigantothermy) and so reduce heat loss.
WebbThe high energy requirement for thermoregulation (about 85%) would, in the absence of huddling, probably exceed the total energy reserves. The data suggest that walking 200 km (from the sea to the rookery and back) requires less than 15% of the energy reserves of a breeding male emperor penguin initially weighing 35 kg.
