Anadolu'da yayılış gösteren bazı Capoeta (Teleostei: Cyprinidae) türlerine ait osteolojik özelliklerin karşılaştırılması

Bu çalışmada, Anadolu’da yayılış gösteren Capoeta cinsine ait altı türün; operkulum, çene ve sirkumorbital kemikleri, sırt yüzgecin sonuncu dallanmamış ışını ve omurga sayısı karşılaştırılmıştır. Örnekler üç farklı gruba ayrılarak incelenmiştir. Birinci grubu C. bergamae (Gediz Nehri) ve C. angorae (Seyhan Nehri), ikinci grubu C. tinca (Nilüfer Çayı) ve C. baliki (Sakarya Nehri) üçüncü grubu ise C. trutta (Dicle Nehri) ve C. pestai (Çayköy Deresi-Eğirdir) türlerine ait örnekler oluşturmuştur. Grupların; operkulum, çene, sirkumorbital kemiklerinin şeklinde ve sırt yüzgecin sonuncu dallanmamış ışının yapısında belirgin farklılaşma bulunmasına karşın, omurga sayısı ve diziliminde önemli bir farklılık belirlenmemiştir.

Comparing the osteological characteristics of some Capoeta (Teleostei: Cyprinidae) species distribution in Anatolia.

In the study, specimens obtained from type localities of six Capoeta species distributing in Anatolia were compared with each other in the view of operculum, jaw and circumorbital bones, last simple dorsal-ray and the total number of vertebrae. There were divided into three different subgroups. The first one is C. bergamae (Gediz River) and C. angorae (Seyhan River), the second C. tinca (Nilufer Stream) and C. baliki (Sakarya River), the third is C. trutta (Tigris River) and C. pestai (Çayköy Stream-Eğirdir). Even though a noticeable differentiation was found in the shapes of jaw and circumorbital bones, and last simple dorsal-ray between the subgroups, no significant difference was determined regarding the number of vertebrae and their arrangement.
