Estimates of historical demographic parameters and their 90% credible intervals in VID and RIN, analysed using IMa [62] and assuming that these two populations have split from a common ancestral population. Parameters scaled by mutation rate and unscaled parameters are provided. Scaled parameters: θ1, θ2, θA = historical effective population size in VID, RIN and the ancestral population, respectively, m1, m2 = migration rate from RIN to VID and VID to RIN, respectively, and t = splitting time. Unscaled parameters: N1, N2, NA = historical effective population size (individuals) in VID, RIN and the ancestral population, respectively, m1, m2 = migration rate (individuals per generation) from RIN to VID and VID to RIN, respectively, and t = splitting time (years).
