Abstract
The desert ecosystem occupies an important position in the composition of global biodiversity. The Tarim Basin is located in south Xinjiang of China and has the world’s second largest mobile desert, the Taklamakan Desert. As an endemic species in this region, Phrynocephalus forsythii has been demonstrated to have a potentially high extinction risk due to climate change. In order to understand the overall genetic status and provide accordant conservation strategies for the species, we investigated the genetic diversity and population structure of P. forsythii from 15 sites in the Tarim Basin using 21 highly polymorphic microsatellite markers. We found significant genetic structure across the study region. We also revealed generally low levels of gene flow between the 25 sites, suggesting individual dispersal and migration may be restricted within populations. In addition, geographical distance and ambient temperature might be important factors in explaining the observed genetic structure. Our results will provide a scientific basis for the future protection of P. forsythii in this area, as well as an important reference for the conservation and management of biodiversity in desert ecosystems.
