Mismatch distribution and Bayesian skyline plots (BSPs) for cytochrome b partial sequences of B. tibetanus sampled in the Qinling Mountains. The two approaches reveal obvious signals of demographic expansion for the Qinling lineages. The mean estimate and both 95% highest posterior density (HPD) limits are indicated. (a,d) The western lineage; (b,e) the eastern lineage; (c,f) the total samples (265 sequences).
