Table 1 Mean ± SEM rate of oxygen consumption (\( \dot{V} \)O2) and mean daily energy expenditure (DEE) of pumas in the Santa Cruz Mountains, calculated for daily behaviours. GPS-derived and accelerometery-derived speeds are compared. See Supplementary Table 4 for equations used to calculate energy costs. ‘*’ indicates that the values are the same for GPS- and accelerometery-derived \( \dot{V} \)O2 since these parameters are not based on speed
