  1. Values for interactions removed during model selection are shown in parentheses from the last model before they were removed. Phylogenetic signal is measured as λ, with 0 indicating no phylogenetic signal and values of 1 corresponding to expectations of Brownian motion. Significance values based on two-sided tests.
