Latitudinal cline in Heterandria formosa allozyme genetic diversity. This linear regression model shows a strong negative relationship between allozymic genetic diversity (He) and latitude (P = 0.002). Black dots indicate genetic diversity of sites below 28°N latitude (dashed line; the temperate-tropical transition), with bioclimatic prediction above the logistic threshold in our Last Glacial Maximum model (Figure 3B), i.e. within the putative LGM refugium.
