Table S3. Prior distribution and posterior estimate of each parameter.T1 and T2 are the time of two divergent events. Tbn_r and Texp_r are the time of bottleneck and expansion duration in a recent event. Tnt is time of an ancestral population before T2 event. N1, N2 and N3 are the effective population size of East, Center and West region respectively. NT is the effective population size of the ancestral population. Nbn_r and Nex_r are effective population size of bottleneck and expansion in a recent event.Tbn and Texp are the time of bottleneck and expansion duration in an ancient event.Nbn and Nex are effective population size of bottleneck and expansion in an ancient event.
