Relationship between body mass (M, g) and basal metabolic rate (BMR, ml of O2 per h) for mammalian orders (see Methods for details) for all data (a; n = 17, r2 = 0.94), data corrected to a common body temperature (36.2°C) by using a Q10 of 3.0 (b; n = 17, r2 = 0.98), and data corrected to 36.2°C for all species excluding Artiodactyla, Lagomorpha, Soricidae (Insectivora), and Macropodidae (Diprotodontia) (c; n = 15, r2 = 0.99). Exponents are shown with 95% confidence intervals.
