Abstract

Eşeysel dimorfizmi belirlemek için Kuzeydoğu Anadolu’dan Darevskia rudis (Bedriaga, 1886) populasyonları üzerinde detaylı yapılan araştırmada 317 örneğin 11 morfometrik ve 30 meristik özelliği analiz edilmiştir. Yedi meristik (Ventral Genişlik, gövdedeki ventrale bağlanan dorsalia sayısı, Sağ Femoral Por, Sol Femoral Por, Soş subdijital Lamel, Tibial Plaklar, Dorsalia). ve dört metrik (Pileus Uzunluğu, Pileus Genişliği, Kafa Uzunluğu, Kafa Genişliği) karakterleri eşeysel dimorfizm örüntüsünde anlamlı bulunmuştur (p <0.05). Erkeklerin kafa boyutları nispeten daha uzundur ve bunla ilgili olarak toplam uzunlukları da dişilerden daha fazladır. Ayrıca eşeysel çağrı bileşikleri de çiftleşme dönemlerinde salındıklarından dolayı femoral por sayılarının erkeklerde dişilerden daha fazla olduğu bulunmuştur.

Sexual Dimorphism In Spiny - tailed Lizard, Darevskia rudis (Bedriaga, 1886) (Sauria: Lacertidae), from Northeastern Anatolia, Turkey

Abstract

Detailed investigations carried out on Darevskia rudis (Bedriaga, 1886) populations from Northeastern Anatolia, Turkey to identify sexual dimorphism. 11 morphometric and 30 meristic features of 317 specimens were analyzed. Seven meristic (Ventral Width, Dorsals attached ventrals at mid-trunk, Femoral Pore Right, Femoral Pore Left, Subdigital Lamellae Left, Tibial Scales, Dorsalia). and four metric (Pileus Length, Pileus Width, Head Length, Head Width) characters were significant in sexual dimorphism pattern (p<0.05). Males have relatively longer head sizes, and related to this snout-vent length than females. Furthermore, it was found that the number of femoral pores are also higher in males than females because signaling compounds might be released in mating seasons.
