Environmental Suitability and Distribution of the Caucasian Rock Agama,Paralaudakia caucasia (Sauria:Agamidae) in Western and Central Asia

摘要

Predictive potential distribution modeling is crucial in outlining habitat usage and establishing conservation management priorities.In this paper we provide detailed data on the distribution of the Caucasian rock agama Paralaudakia caucasia,and use species distribution models(MAXENT) to evaluate environmental suitability and potential distribution at a broad spatial scale.Locality data on the distribution of P.caucasia have been gathered over nearly its entire range by various authors from f ield surveys.The distribution model of P.caucasia showed good performance(AUC=0.887),and predicted high suitability in regions mainly located in Tajikistan,north Pakistan,Afghanistan,southeast Turkmenistan,northeast Iran along the Elburz mountains,Transcaucasus(Azerbajan,Armenia,Georgia),northeastern Turkey and northward along the Caspian Sea coast in Daghestan,Russia.The identifi cation of suitable areas for this species will help to assess conservation status of the species,and to set up management programs.
