Figure 2

Graphical representation of results of migrations estimated using MIGRATE-N among the four regional population groups. Maximum-likelihood estimates and 95% confidence intervals (in parentheses) of the long-term migration rate (M) and mutation-scaled effective population size (θ) using the MIGRATE-N program are shown. Bold values indicate that migration was asymmetrical as determined from non-overlapping 95% confidence intervals; arrows represent the direction of gene flow among regions or among sites. C, central; N, north; S, south; SE, southeast.
