(a) Weighted log basal metabolic rate (BMR) (ml O2 h−1) against weighted log body mass (g) for each 801 mammal species in the study, across terrestrial categories. Regression lines are in black and confidence intervals are present in grey. Aquatic mammals demonstrated significantly higher BMRs for a given body mass than all other terrestrial groups, apart from ‘flying’ in the PGLS. No other groups were significantly different. (b) Box and jitter plot showing the residuals of weighted log basal metabolic rate (BMR) (ml O2 h−1) against weighted log body mass (g) across five terrestriality categories for all 801 mammal species used in this study.
