Estimates of genetic clustering among the Eastern, Western and Migratory regions based on the full SNP set. (a) Bayesian analysis of population structure and admixture estimated in STRUCTURE, with bars along the x-axis representing individuals within each region and the y-axis representing their proportion of group membership under models estimated for 2, 3, and 4 populations (K). (b) Principal components analysis (PCA) plotted on the first two PCs, with points representing individual samples, colors representing sampling region, and ellipses representing clustering of each region.
