Figure 3.

Scatterplot of pairwise genetic divergence between populations (F_STmean for all 10 microsatellite loci) plotted by geographical distance in kilometers between them. Comparisons that include the northernmost population (Richard Toll) are shown with square points, while all others are shown with circular points. An overall test for isolation by distance was not significant (Mantel test of matrix correlation, P = 0.304).
