Population assignment using STRUCTURE version 2.3.2. Sulfidic and surrounding non-sulfidic habitats of (ac) G. holbrooki, (d) G. eurystoma/sexradiata, and (e) G. hubbsi. K = 1 was recovered as the most likely number of genetic clusters in c, K = 2 in a and e, and K = 3 in b and d; given are individual relative assignment values in yellow (sulfidic habitats; left side) as well as blue and olive (non-sulfidic sites; right side), divided by a black line and sorted by the relative assignment score for each population separately. Numbers correspond to sites as described in Table 1
