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.

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.
