Fig. 4: Introgression between brown (Ursus arctos; arctos) and American black (U. americanus; amer) bear populations estimated using DFOIL. Population order was varied due to estimates that lineage divergence initiated around the same time in each species.

From: Phylogeography of introgression: Spatial and temporal analyses identify two introgression events between brown and American black bears

Fig. 4

The five-taxon phylogeny was organized as: A ((arctos- Europe, arctos- other), (americanus- western, americanus- eastern)), Tremarctos ornatus; or B ((americanus- western, americanus- eastern), (arctos- Europe, arctos- other), Tremarctos ornatus. The U. arctos p2 or p4 population varied between Japan (maroon), ABC Islands (dark brown), and Lower 48 (light brown). Each independent run set a single animal in each position, and three animals from each population were selected and DFOIL run for all four-way combinations. Violin plots were produced from the number of 100 kb windows which DFOIL assigned to each introgression pattern divided by the total windows tested (n = 12,115).
