| 英文摘要 | Background Triplophysa stoliczkae is the most widespread species in the genus Triplophysa and may have originated from morphological convergence. To understand the evolutionary history of T. stoliczkae, we employed a multilocus approach to investigate the phylogenetics and the morphological evolution of T. stoliczkae on the Qinghai-Tibetan Plateau. Results All phylogenetic analyses (two mitochondrial and five nuclear loci), a genealogical sorting index and species tree inferences suggested that T. stoliczkae consists of distinct lineages that were not closest relatives. The time estimation indicated that the divergence events between "T. stoliczkae" and other Triplophysa species occurred from approximately 0.10 to 4.51 Ma. The ancestral state analyses supported the independent evolution of T. stoliczkae morphology in distinct lineages. The morphometric analysis and convergence estimates demonstrated significant phenotypic convergence among "T. stoliczkae" lineages. Conclusions Triplophysa stoliczkae includes 4 different lineages with similar morphologies. The increasingly harsh environments that have occurred since the Pliocene have driven the occurrences of scrape-feeding fish in the genus Triplophysa. Morphological adaptations associated with scrape-feeding behavior resulted in convergences and the artificial lumping of four different species in the nominal taxon T. stoliczkae. A taxonomic revision for T. stoliczkae is needed. |
