Figure 6

Comparisons between morphological and molecular population divergence and isolation-by-distance. Data points are pairwise comparisons between sets of 12 populations, and differences are tested with Mantel tests (see text for details). (a) Morphological distances between populations are significantly correlated with molecular distances estimated as pairwise Fst-values obtained from AFLP analysis. (b) Molecular population divergence shows significant evidence of isolation-by-distance. (c) There is no significant evidence of isolation-by-distance for morpology.
