Distribution Modeling of the Caucasian Rock Agama Paralaudakia caucasia (Eichwald, 1831), (Sauria: Agamidae) Based on an Updated Data Set

Natalia Borisovna Ananjeva, Eugeny Golynsky, Lyudmila Mazanaeva


We present results of analysis and predictions of the potential distribution of the Caucasian rock agama Paralaudakia caucasia (Eichwald, 1831), based on an updated data set and using a distribution model generated with software Maxent (www.cs.princeton.edu/~schapire/maxent). The model was based on an updated data set of 238 localities, including 74 new records from Daghestan and Tajikistan. According to the generated model, the most suitable habitats of the Caucasian rock agama Paralaudakia caucasia are located in the Caucasus (southeastern Ciscaucasia and eastern Transcaucasia), south Turkmenistan and north-eastern Iran.
