Phylogenetic reconstructions based on mtDNA (left) and nuDNA (right). Both trees are generated from a Bayesian inference. Values on the key nodes indicate the posterior probabilities (PPs) obtained in the Bayesian inference and bootstrap support (BS) from the maximum likelihood analyses (PP/BS). The background colors are denoted as those in Fig. 1. Triplophysa stoliczkae individuals are labeled into 4 groups corresponding to the mtDNA clades, with circles for mtDNA and squares for nuDNA. The genealogical concordance between mtDNA and nuDNA trees are evaluated by the genealogical sorting index (gsi) values listed in the box
