Additional file 8: of Long-term sky islands generate highly divergent lineages of a narrowly distributed stream salamander (Pachyhynobius shangchengensis) in mid-latitude mountains of East Asia

Figure S3. Bayesian skyline plot of effective population size in P. shangchengensis based on the mtDNA data (a–f). The BSP analyses of the KJY population was calculated excluding the individuals with two haplotypes clustered more closely to the BYM population. The x-axis indicates time in Mya BP, and the y-axis indicates the effective population size in units of Neτ (the product of effective population size and generation time in Mya). The blue areas represent 95% highest posterior density. Time is expressed in million years. (TIF 2011 kb
