Population genetic structure of 11 populations of the American pika (Ochotona princeps) sampled from California (O. p. schisticeps), Colorado (O. p. saxitilis), Nevada (O. p. princeps) and Montana (O. p. princeps) based on 27,670 SNPs. a The first and second principal components (PCs) from the PCA are plotted for each individual (points were jittered to avoid overplotting). b An unrooted neighbor-joining tree analysis produced a tree topology reflecting strong evolutionary differentiation among pika subspecies. c A hierarchical Bayesian model (entropy) shows the assignment probability estimated for each individual for each of four genetic clusters (k = 4). Symbols are only used to delineate different populations within the same region and do not correspond to those found in Fig. 2.
