Fig. 2.

Inferred population connectivity. The recent immigration history of each sampled locality (sink) is depicted according to the locality they were inferred to have originated from (source) (a, d). The grayscale of each cell in these plots depicts the relative proportion of individuals in the sink population that were estimated to be recent immigrants from each locality along the x-axis. Cells on the minor diagonal correspond to the proportion of native individuals. Pruned conditional genetic networks (b, e) and posterior estimates of admixture proportion identified by TESS analysis (c, f) are also displayed. The top row shows SSR-based results, the bottom shows the SNP-based results. Locality numbers follow Fig. 1. Localities shared between SSR and SNP datasets are denoted by gray-shaded arrows (for a similar figure based exclusively on these shared localities, see Fig. S6)
