L-HPD, lower 95% Highest Posterior Density; H-HPD, higher 95% Highest Posterior Density. θ, demographic parameter estimated by IMa2. N, calibration of θ in number of individuals. m, migration parameters estimated by IMa2. M, calibration of m in number of individuals. N, north of the barrier; S, south of the barrier; A, ancestral population; forward in time, N-S, migration from north to south; S-N, migration from south to north.
