  1. Model parameters indicate estimates without use of molecular rate of evolution for six parameters (IMa output values). Demographic rates represent parameters scaled to rates of molecular evolution. Values are averages of two runs of mean parameter estimates and the 95 % highest posterior densities (HPD) intervals of each parameter: effective population sizes (Ne, individuals), migration rates (Nm, migrants per generation), estimated time since divergence (t, years). Population size (Ne) based on the average generation time (T) of 11 years for a high (0.9) annual adult survival rate. Habitat type abbreviations are as follows: SCHI cloud forests from San Luis Potosí to Oaxaca and Chiapas, CALY xeric vegetation in central Oaxaca, BREE tropical deciduous forests in Chiapas
