  1. Results of phylogenetic comparative tests for associations between range-size and biogeographical and ecological variables using Phylogenetic Generalized Least Squares. The maximum likelihood estimate of evolutionary constraint (alpha, α) is provided, and parameter estimates given that maximum likelihood. Significant relations (regression slope significantly different of zero) are given in asterisks: * P < 0.05; ** P < 0.005 (Bonferroni critical value for ten tests).
