Fig. 2.

Bayesian inference tree displaying genetic divergence of plateau pika based on mtDNA. Estimates of divergence times with 95% posterior probability intervals are indicated above the branches. Posterior probabilities are indicated under the branches.

Fig. 3.

Bayesian clustering of plateau pika populations inferred with the program BAPS using mtDNA markers. (a) Admixture analysis for K=4. (b) Spatial clustering model for K=4. Populations with yellow, red, blue and green represent group I, II, III and IV respectively.

Fig. 4.

Delta K plotted against the number of genetic clusters (K).

Fig. 5.

Bayesian individual-based clustering of pika populations with K, 3; K, 4 and K, 5. Each individual is represented by a single vertical bar divided into K colors. The colored segments shows the estimated proportion of membership to each genetic cluster.
