Summary of association index for phylogeographic analysis.

Results of Bayesian Tips Significance Tests (BaTS). Association Index (AI) and Parsimony Score (PS) tests the global association between a trait and tree topology taking into account the level of uncertainty in the phylogenetic reconstruction. The Monophyletic Clade (MC) index allows to test whenever each trait is associated with phylogeny. The observed mean and its associated 95% confidence intervals (Upper and Lower CI) were obtained by analyzing trees sampled during the MCMC (Bayesian phylogenetic reconstruction). The null mean and its associated confidence intervals were obtained after randomly distributing the traits in the phylogeny (100 replica). Significance level is the p value for the statistical hypothesis test for equality between the observed index and that expected under no-association.
