Mammalian metabolic rate (MR)=aMbb. All regressions are presented in standardised units (BMR in ml O2h−1; Mb in g). SMR, standard metabolic rate; BMR, basal metabolic rate; RMRt, thermoneutral resting metabolic rate; FMR, field metabolic rate; RMRpp, peak postprandial resting metabolic rate; MMRc, cold-induced maximum metabolic rate;MMRe, exercise-induced maximum metabolic rate; see text for details.
