Fig. 1: Sample distribution and two species ancestry clustering between brown (Ursus arctos; squares) and American black bears (U. americanus; circles).

Fig. 1

A, B Global range maps of brown (light brown) and American black (dark grey) bears with geographic locations of samples analyzed in this study shown as points colored based on broad ancestry from seven clusters across both species. Inset in panel A shows detailed view of Hokkaido, Japan, while the inset in panel B shows southeast Alaska, USA. C Clustering of all samples of both species showing distinct species clustering at two clusters (cross-validation shown in Fig. S2), the best supported model at five clusters, and seven clusters which were used as the units for most analyses throughout the paper. Single species clustering analyses shown in Figs. S3 and S4.
