Abstract
Oxygen consumption rates and levels of spontaneous activity were recorded simultaneously for mice, both singly and in groups, over 24 hr periods at temperatures ranging from 8 to 37[degree]C. There was marked 24-hr variation in both metabolic rate and activity, with maxima during the night; the amplitude of the variation diminished at the lower environmental temperatures. At 28-33[degree]C environmental temperatures, increased activity was associated with an increased oxygen consumption rate. At 8 and 15[degree]C, increased activity was accompanied by only a small increase in oxygen consumption These results show that thermogenesis from spontaneous activity can take the place of thermoregulatory heat production in the cold.This publication has 2 references indexed in Scilit:
