Habitat Suitability Mapping of Anatololacerta danfordi (Günter, 1876) in Isparta-Sütçüler District

Abstract

Anatololacerta danfordi (Günter, 1876) is an endemic lizard species of the Lacertidae family in Turkey herpetofauna. This lizard species is spreading in the Taurus Mountains and in the appropriate habitats around it. This study was carried out with the aim of determining and mapping suitable habitats for the target species with Maximum Entropy method in Sütçüler (Isparta) region in Western Mediterranean. As a result of the field work between May-October of 2014, 33 present data of this species were obtained. Relationships between the 21 environmental variables and present data of target species, which do not correlate with each other, such as bio climate variables, vegetation indices derived from satellite data or digitized baseline maps, are modeled and mapped by MaxEnt software. According to the habitat suitability model of Anatololacerta danfordi (training data set AUC: 0.916, test data set AUC: 0.898); bedrock, stream density, slope, ruggedness, landform index, radiation index, and land cover/use classes have been the limiting factors in the distribution of Anatololacerta danfordi.

Isparta-Sütçüler Yöresinde Anatololacerta danfordi (Günter, 1876)’nin Habitat Uygunluk Haritalaması

Abstract

Anatololacerta danfordi (Günter, 1876) Türkiye herpetofaunasında Lacertidae familyasına ait endemik bir kertenkele türüdür. Bu tür Toros Dağları ve çevresindeki uygun habitatlarda yayılış göstermektedir.  Bu çalışma Batı Akdeniz de yer alan Sütçüler (Isparta) yöresinde Maksimum Entropi yöntemi ile hedef tür için uygun habitatları belirlemek ve haritalandırmak amacı ile gerçekleştirilmiştir. 2014 yılının Mayıs-Ekim ayları arasında gerçekleştirilen arazi çalışması sonucunda sahada türe ait 33 örnek alanda var verisi elde edilmiştir. Bio iklim değişkenleri, uydu verilerinden türetilen bitki indeksleri ve coğrafi bilgi sistemleri kullanılarak üretilen veya sayısallaştırılan altlık haritalar olmak üzere toplamda birbiriyle korelasyon göstermeyen 21 çevresel değişken ile hedef türe ait var verileri arasındaki ilişkiler MaxEnt yazılımı ile modellenmiş ve haritalanmıştır. Anatololacerta danfordi için elde edilen habitat uygunluk modeline göre (eğitim veri seti AUC: 0.916,  test veri seti AUC: 0.898) türünün dağılımını etkileyen çevresel değişkenlerin anakaya, dere yoğunluğu, eğim, engebelilik, arazi yüzü şekli, radyasyon indeksi ve arazi örtü/kullanım sınıfları olduğu belirlenmiştir.
