  1. *Results produced using age estimation A. For the diversification rate analysis, detected shifts are marked by their probability. The mean speciation rate (species/Ma) per clade is detailed with the 5%, and 95% HPD in brackets below. For the bioclimatic niche analysis, shifts are marked by their probability, and the new phenotypic optimum (PC1 score optimum) is detailed with the standard error in brackets below. HPD, highest posterior density; pp, posterior probability; ML, maximum likelihood bootstrap support; Ma, million years; shift probability, marginal probability of rate shifts.
