  1. Correlations between character transitions were evaluated against 1000 bootstrap ML topologies to correct for phylogenetic bias. To carry out correlations in BayesTraits, all characters were coded as binary (e.g., presence/absence). Median likelihood scores under each model are shown, although likelihood differences were evaluated by pairwise comparison for each bootstrap tree.
