  1. t Denotes divergence time (in years) between the two populations assuming a standard mutation rate of 5.56×10-4, whereas t est_mut denotes divergence time (in years) assuming a mutation rate of 3.00×10-4, reflecting the mutation rate estimates obtained using DIYABC. q 1 denotes effective population size of LIL, q 2 effective population size of HAL or MOS and q A effective population size of the ancestral source population prior to divergence. m 1 denotes migration rate per generation from MOS or HAL into LIL, and m 2 denotes migration rate from LIL to HAL or MOS. The analyses are based on coalescence, but to increase clarity estimates of m 1 and m 2 are reported in forward-time. All estimates consist of modes and 90% credible intervals (in parentheses).
