Abstract

Bu çalışmada, Türkiye’nin Elazığ ve Malatya illerinden elde edilen 40 adet (20 dişi, 20 erkek) Avrupa tavşanı kullanıldı. Örnekler maxilla’ların ventral’ine 23’er adet landmark konularak değerlendirildi. Thin Plate Spline (TPS) programı ile konulan landmarklar Morpheus programı ile standardize edildi. Verilere pairwise testi, principle component analizi (PCA) ve discriminant Fonksiyon Analizleri DFA) uygulandı.  Geometrik morfometri teknikleri kullanılarak yapılan istatistiksel analiz sonuçları Avrupa tavşanı (Lepus europaeus) örneklerinde eşeysel dimorfizm olmadığını göstermiştir.

Sexual Dimorphism of the Maxillae in European Hare Using Geometric Morphometric Approach

Abstract

In this study, 40 European hares (20 male and 20 female) that were obtained from the provinces of Elazığ and Malatya in Turkey, were used. The samples were evaluated by placing 23 landmarks on the ventral of the maxilla. After the landmarks were placedonto the pictures, which were developed by means of Thin Plate Spline (TPS) program, the landmarks were standardized by using Morpheus program. Pairwise test, principle component analysis (PCA) andDiscriminant Function Analysis (DFA) were applied to the data. The result of the statistical analysis with geometric morphometric techniques showed no sexual dimorphism (SD)in Europanhares (Lepus europaeus).
