F I G U R E 4 Assigned ancestry plot using AIC criteria determining optimal K in Riverscape genetics of the orangethroat darter complex

F I G U R E 4 Assigned ancestry plot using AIC criteria determining optimal K of 5. Each color corresponds to a distinct genetic cluster, and each bar represents an individual's assigned ancestry to each cluster. Names above chart correspond to river basin (HUC6). EB—E. burri, EP— E. pulchellum, ES—E. spectabile, and EU—E. uniporum. Glaciated and unglaciated correspond to areas that were/were not covered in ice during the last glacial maximum.
