Some investigations on the taxonomy of the Emys orbicularis (Linnaeus, 1758) (Testudinata: Emydidae) specimens from Aegean Region of Turkey

Bu çalışmada Türkiye’nin Ege Bölgesi’ndeki dokuz farklı lokaliteden toplanan 71 E. orbicularis örneği incelenmiştir. Morfolojik karşılaştırma için örneklerin 19 metrik karakteri ve bu metrik karakterlerden geliştirilmiş 35 oran çeşitli populasyonlar arasındaki fark ve benzerlikleri ortaya koymak için incelenmiştir. Farklı populasyonlara arasındaki morphometrik karşılaştırmalara ilaveten, renk ve desen özellikleri ile eşeysel farklılıklar da dikkate alınmıştır. Sonuç olarak, Ege Denizi kıyılarına yakın yaşayan populasyonların Emys orbicularis hellenica’ya benzer olduğu, buna karşın Orta Anadolu’ya yakın populasyonların ise daha çok Emys orbicularis luteofusca’ya benzer olduğu görülmüştür.

Türkiye' nin Ege Bölgesi' nden Emys orbicularis (Linnaeus, 1758) (Testudinata: Emydidae) örneklerinin taksonomisi üzerine bazı araştırmalar

In this study, 71 Emys orbicularis (Linnaeus, 1758) specimens from nine different localities in the Aegean region of Turkey were examined. For morphological comparison, 19 metric characters of the specimens and 35 ratios developed from these metric characters were investigated to establish the differences and similarities among various populations. In addition to the morphometric comparisons between the different populations, colour and pattern characteristics and sexual dimorphism were also considered. As a result, it is evident that the populations living near the coast of the Aegean Sea are similar to Emys orbicularis hellenica, whereas the populations closer to central Anatolia are somewhat similar to Emys orbicularis luteofusca.
