F I G U R E 8 in Riverscape genetics of the orangethroat darter complex

F I G U R E 8 FST isolation by distance plots. Segregation of allele frequencies is shown between pairs of basins v. geographic (river/land) distance. (a, b). All basin pairs in this study with comparisons within regions shown in black and between regions in gray for overland distance (a) and river distance (b). (c, d). Within region site comparisons, grouped by regions for overland distance (c) and river distance (d). The Tennessee River and Great Lakes regions were omitted because one basin was sampled in each region.
