Contrasting population differentiation in two sympatric Triplophysa loaches on the Qinghai-Tibet Plateau.

ABSTRACT: Genetic differentiation in aquatic organisms is usually shaped by drainage connectivity. Sympatric aquatic species are thus expected to show similar population differentiation patterns and similar genetic responses to their habitats. Water bodies on the Qinghai-Tibet Plateau (QTP) have recently experienced dramatic physicochemical changes, threatening the biodiversity of aquatic organisms on the "roof of the world." To uncover ecological genetics in Tibetan loaches (Triplophysa)-the largest component of the QTP ichthyofauna-we characterized population differentiation patterns and adaptive mechanisms to salinity change in two sympatric and phylogenetically closely related Tibetan loaches, T. stewarti and T. stenura, by integrating population genomic, transcriptomic, and
