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.
