ΘCSE, ΘSW, ΘA represent the scaled effective population sizes (Ne) of CSE lineage, SW lineage of T. hemsleyanum, and the ancestral population, respectively. mcse-sw and msw-cse refer to the scaled migration rates forward in time from CSE to SW lineage and vice versa. t is the time since ancestral population splitting in mutational units. 2NCSEMCSE-SW and 2NSWMSW-CSE are the effective migration rates (number of migrants per generation). All estimates include the per gene mutation rate V (geometric mean of the mutation rates of all the loci). Parameters in the first six columns are scaled by the mutation rate, while the rest are scaled by years or individuals.
