Correspondence is measured as absolute correlation (r) in the pair-wise tests, and absolute standardized partial regression (g) in the simultaneous tests. The probability (P), of the null hypothesis of no association, between gene flow (dependent variable) and mtDNA lineage (mtDNA), isolation-by-distance (Prox), and type of UV pattern (UV) (independent variables) is based on 10,000 randomizations. Significant correspondence in bold. The UV pattern matrix is based on taxonomic distance. The same results are found when the UV pattern matrix is based on Mahalonobis distance (UV-F_STassociation: pairwise r = 0.52, P = 0.0000; partial g = 0.49, P = 0.0005).
