All variables were log₁₀ transformed. GR = geographic range size; BMR = basal metabolic rate; LIGR = latitude-independent GR; MIBMR = mass-independent BMR. Standard error of the slope (b) and intercept (a) are in parentheses. Statistically significant (p < 0.05) and “marginally significant” (0.10 < p > 0.05) slopes are indicated by p-values in bold.
