Figure 5From: Paleoclimatic modeling and phylogeography of least killifish, Heterandria formosa: insights into Pleistocene expansion-contraction dynamics and evolutionary history of North American Coastal Plain freshwater biotaThe six graphs at left show the frequency distributions of the numbers of pairwise cytb differences among H. formosa individuals for each SAMOVA-inferred population group and regional group, with confidence intervals on expected values derived from parametric bootstrapping (104 iterations) in Arlequin. Mean estimated timing of population expansions (circles) and 95% confidence intervals from parametric bootstrapping (bars) are plotted at right, with grey shading indicating time since onset of the LGM.Back to article page
