Changes in body mass, resting metabolic rates (RMR), lower critical temperature (LCT), shivering threshold temperature (STT), body temperature in thermoneutral zone (Tb in TNZ), thermal conductance (C) and respiratory quotient in 7 to 30 - day-old Adélie penguin chicks. Values are means ± S.E.M. from 9–12 individuals per age. *p<0.05, significantly different from D7; † p<0.05, significantly different from D15.
