Presented here are highest posterior estimates and 95 % upper and lower posterior density bounds of parameters scaled by mutation rate from MCMC analyses (M-Mode) and joint posteriors based on the full model in L-mode. M-mode analyses are averages of seven independent runs for the full dataset and three independent runs with the mitochondrial DNA locus (ND2) removed. L-mode analyses are based on a total of 300,000 genealogies combined from seven independent analyses
