Özet:

 This study, aimed to determine the shape features of the New Zealand rabbit skull and to reveal the differences between individuals and genders in terms of shape features. For this purpose, the geometric morphometry method was used. A total of 10 female and 10 male New Zealand Rabbit craniums were used. The skulls were photographed in a dorsal, ventral and lateral view, and the mandible was photographed in a lateral view. Homologous landmarks were marked on the photographs. Consensus graphs were created by the TpsRelw Version 1.70 program. Additionally, principal component analysis and relative warp analysis were performed. As a result of the study, principal components explained 34.813, 57.225 and 42.427 of the total shape difference in the dorsal, ventral and lateral views of the skull, respectively. In the first principal component graph obtained as a result of principal component analysis, no significant clustering was observed between genders. According to the graphics obtained in the MorphoJ program, inter-individual variation was detected mainly in the viscerocranium, followed by the neurocranium. This study will contribute to morphological and archaeological studies on rabbit skulls.

 Bu çalışmada Yeni Zelanda tavşanı kafatasının şekilsel özelliklerinin belirlenmesi ve bu özellikler bakımından bireyler arası ve cinsiyetler arası farklılıkların ortaya konulması amaçlandı. Bu amaçla geometrik morfometri yöntemi kullanıldı. Toplamda 10 adet dişi ve 10 adet erkek Yeni Zelanda Tavşanı kafatası kullanıldı. Kafatasları dorsal, ventral ve lateral görünümde, mandibula lateral görünümde fotoğraflandı. Fotoğraflar üzerinde homolog londmarklar işaretlendi. Konsensüs grafikleri TpsRelw Sürüm 1.70 programı tarafından oluşturuldu. Ayrıca temel bileşen analizi ve relative warp analizi yapıldı. Çalışma sonucunda temel bileşenler, kafatasının dorsal, ventral ve lateral görünümlerindeki toplam şekil farkının sırasıyla 34,813, 57,225 ve 42,427sini açıklamaktadır. Temel bileşenler analizi sonucunda elde edilen birinci temel bileşenler grafiğinde cinsiyetler arasında anlamlı bir kümelenme gözlenmedi. MorphoJ programında elde edilen grafiklere göre bireyler arası varyasyonun en çok viscerocraniumda, ardından da neurocraniumda olduğu tespit edildi. Bu çalışmanın tavşan kafatasları üzerinde yapılacak morfolojik ve arkeolojik çalışmalara katkı sağlayacağına inanıyoruz.
