For each independent variable, we report the parameter estimate (Beta), t-statistics (T), P value (P; two-sided test), and the model statistics including the degrees of freedom (df), the maximum likelihood estimation of the phylogenetic signal (λ) and R2. Significant differences are indicated in bold. Results of analyses controlling for allometry are available in Supplementary Table 2. See Supplementary Table 3 for sexual system and sex-specific sample sizes.
