Fig. 1. Relationship between the percentage of large herbivores in a basal metabolic rate (BMR) data set and the coefficient of variation (CV, the standard deviation of residuals from a ln-ln allometric relationship; Garland, 1984) and scaling exponent (shown ±95% CI) of the allometric relationship between BMR and body mass. Both correlations are significant (CV: r=0.92, P<0.0001; scaling exponent: r=0.85, P=0.0003). Data sources are provided in Table 1.
