Table 4.

Results from Bayesian Phylogenetics and Phylogeography analyses for each combination of priors. The posterior probability (PP) values are averages from two independent runs of module A11. Each species is represented by a single letter abbreviation corresponding to the species epithet, e.g. T is B. transfuga.
