Principal Component Analysis (PCA) of caribou sampled in the southern Rocky Mountains of Canada. Circles represent caribou individuals, and colors represent DUs (in Panel a), herds (in Panel b) or proportion of assignment to the two major genetic clusters detected with STRUCTURE (in Panel c). Dashed circles in panel B indicate the caribou population groups we detected, which were then used in analyses of adaptive divergence: ALP = À La Pêche; COL = Columbia North, Purcell South, and South Selkirk; JNP = Jasper and Banff; CR = Moberly, Quintette, Redrock-Prairie Creek, Hart South, and North Cariboo
