Population pairwise F _st estimates computed in Arlequin v.3.5.1.3. are shown below the diagonal, while Nei’s (1978) standard genetic distances (D _S) computed in Genetix v.4.05.2 with 10,000 permutations are reported above. All F _st values were significant at p < 0.001 following 1,000 permutations. Non-significant F _st and D _S values (p > 0.05) are presented in bold type
