Genetic differentiation of the Schizothorax species complex (Cyprinidae) in the Nujiang River (upper Salween).

ABSTRACT: Phenotypically diverse species from recently evolved groups always share allele/haplotype due to insufficient differentiation in the early process. In this study, we performed population genetics analyses using sequences from the mitochondrial cytochrome b gene, and two nuclear genes to investigate the genetic differentiation of the closely related Schizothorax species complex, comprising a group of alpine fish living in the Nujiang River. The results from both mtDNA and nDNA markers revealed relatively low but pronounced genetic differentiation among the three Schizothorax species, i.e., Schizothorax gongshanensis, S. lissolabiatus, and S. nukiangensis. However, haplotype sharing was frequently occurred among the three species. Divergence time estimation suggested the last glaciation on t
