  • We measured the density of the burrows of Phrynocephalus vlangalii at the Zoigê Wetland at elevation about,NW Sichuan,by the quadrate method,and the depth by digging and using a blanch of alpine willows in September 2002.The density of P.vlangalii burrows declined with the plant coverage (r=-0.81,P<0.01),P.vlangalii shows preference to the desert with low plant coverage and could be used as one of indicator species for desertification of grassland.The depth of dwelling burrows was ≥74 cm,which is beyond the layer of frozen earth,living in these burrows is a behavioral mechanism of P.vlangalii to protect themselves from extreme low temperature,and the burrows with depth <74 cm may be used only for avoiding predation during foraging.
