  1. θ S θ N and θ A indicated the effective population size of the southern region, the northern region and the ancestral populations, respectively. The migration rate is indicated as backwards in time, e.g. migration parameter (m N>S) indicates migration from northern to southern population in coalescent time (i.e. from population southern to northern forward in time). 2N N m N population migration rate from southern to northern population, 2N S m S population migration rate from to northern to southern population. The divergence time (T) was scaled by geometric means of substation rates per locus (1.498 × 10−6)
