(a) Hierarchical F-statistics computations were carried out for the entire sample based on 3 hierarchical levels: (1) populations (sampling sites), (2) populations grouped into four clusters, and (3) clusters 3 and 4 grouped together. (b)-(d) Hierarchical F-statistics were computed separately for clusters 1–3 (containing populations from Ssese, Koome and Buvuma islands, respectively), based on 2 levels: (1) populations, and (2) populations grouped into island and mainland.
