Habitat Suitability Evaluation and Corridor Construction of Phrynocephalus axillaris in Xinjiang
Protecting or rebuilding landscape connectivity in fragmented habitats is considered to be a key strategy for con-serving biodiversity and ecosystems,facilitating the movement of wildlife populations as well as adapting to climate change.And habitat corridors are a common strategy for restoring and protecting landscape connectivity.Taking the Tarim Basin as an example,using 21 species distribution locations of Phrynocephalus axillaris,the MaxEnt model was developed to ana-lyze the habitat suitability of Ph.axillaris,and the Linkage Mapper tool was used to construct a potential ecological corridor suitable for the spread of Ph.axillaris by integrating vegetation type,geographical factors,human disturbance and other fac-tors in the leaf city.The results showed that the environmental factors had great influences on the potential suitable distribu-tion area of Ph.axillaris,which included the coldest average temperature,the coldest month minimum temperature,vegeta-tion cover type,the coldest quarterly precipitation,slope and dryest monthly.Of the 21 recorded distribution locations of the leaf city sand lizard,six were in the best habitat,six were in suitable habitat,and nine were in low suitable habitat.Based on the distribution of suitable areas of Ph.axillaris analyzed by MaxEnt model,a total of 32 ecological corridors were con-structed,including 11 long-distance corridors and 21 relatively short-distance corridors.Among them,short-distance corri-dors connect adjacent habitats,and long-distance corridors connect north-south habitats.The results will fill the gap in the study of ecological corridor and habitat suitability of Ph.axillaris in this area,help optimize the habitat pattern of this spe-cies,provide scientific reference for the sustainable development of reptile species,and provide reference for species con-servation and protected area planning of desert ecosystems.
