The effects of migration rates on spatial patterns of genetic diversity at expansion fronts.

<p>The migration rates varied from 0.001 to 0.4 (red: 0.01, yellow: 0.1, green: 0.2, blue: 0.4). The spatial patterns of genetic diversity were described by width and number of genetically homogeneous domains (A, B) and genetic clines (C, D), pairwise differences in PX (E), PXY (F) and Pc (G), and the mean frequency of the power spectrum (H)). The solid and dashed lines indicated BLRE and PhLRE, respectively. The value of <i>r</i> was set as 3; initial allele frequency = 0.5; and the number of generations to complete a boundary motion equal to 6000.
