Habitat suitability mapping of lizard species in Isparta-Sutculer region

This thesis was carried out to determine the relations between lizard species which appeared in Isparta-S?t??ler district and environmental variables, and to acquire the habitat suitability maps of lizard species in the study area. As a result of field studies performed in 251 sample plots (100 x 100 m), 6 lizard species (Stellagama stellio, Anatololacerta danfordi, Anatololacerta pelasgiana, Ophisops elegans, Lacerta trilineata, Chamaeleo chamaeleon) were detected. The relationship between 4 lizard species (Stellagama stellio, Anatololacerta danfordi, Anatololacerta pelasgiana, Ophisops elegans) which have sufficient presence data in terms of statistical and 24 environmental variables were analyzed and mapped by Maxent method. The standard deviation values between training data set ROC values and test data set ROC values were used to select the optimum model from among the great numbers of species distribution models which acquired for each lizard species. The model which has minimum standard deviation value was selected as a optimum model. When the habitat suitability model (ROC: 0,990-0,984) obtained for S. stellio was examined, the environmental factors affecting the distribution of the species were determined as the bedrock, annual index, distance to water, topographic position index, land cover/use classes and altitude. The environmental variables which created the habitat suitability map (ROC: 0,916-0,898) for A. pelasgiana were bedrock, annual precipitation, stream density, slope, ruggedness, EVI (enhanced vegetation index), land position index, total solar ilimunation index, distance to water, land cover/use classes and altitude. The environmental variables affecting the distribution of A. danfordi (ROC: 0,916-0,898) were found as bedrock, stream density, slope, ruggedness, land position index, radiation index, land cover/use classes. Environmental factors that create the optimum habitat suitability model for O. elegans (ROC: 0,960-0,929) were determined as the bedrock, annual precipitation, slope, ruggedness, land position index, land cover/use classes.
