Distribution of chromosomal forms of Nannospalax nehringi (Satunin, 1898) (Rodentia: Spalacidae) in Çankırı and Çorum provinces, Turkey

Kör fareler toprak altı yaşama uyum sağlamışlardır. Bu canlılar Türkiye’de 2n = 36’dan 2n = 60’a kadar değişen geniş bir kromozomal varyasyona sahiptirler. Bu çalışma Çankırı ve Çorum illerinin çevresindeki 38 lokaliteden yakalanan 91 Nannospalax nehringi (Nehring, 1898) örneği üzerinde yapıldı. Aynı 2n değerlerine sahip farklı formlar Türkiye’deki coğrafi k yayılımlarına gore bir harf ile belirtildi. İç Anadolu formları için C, kuzeydekiler için N, güneydekiler için S, doğudakiler için E ve batıdaki formlar için W kullanıldı. Karyotip analizleri sonucunda N. nehring’nin bu alanlarda 2n = 54C, NF = 74; 2n = 56N, NF = 72; 2n = 58N, NF = 74 ve 2n = 60 için iki forma (NF = 78 ve NF = 82) sahip olduğu belirlendi. Bu çalışma Çankırı ve Çorum çevresindeki körfare kromozomal formları ve bunların yayılışlarındaki boşlukarı doldurdu. 2n = 54C, 56N, 58N ve 60 formlarının bölgedeki yayılışları aydınlatıldı.

Çankırı ve Çorum illerindeki Nannospalax nehringi (Satunin, 1898) (Rodentia: Spalacidae) kromozomal formların dağılımı

Mole rats have adapted to living underground and have a wide range chromosomal variation in Turkey, ranging between 2n = 36 and 2n = 60. Th is study was performed on the subterranean mole rats of the Nannospalax nehringi (Nehring, 1898), sampled around Çankırı and Çorum provinces in central Anatolia, and the karyotypes of 91 specimens across 38 localities were analyzed. Diff erent chromosomal forms that have the same 2n values were assigned letters according to their geographic locations in Turkey: C for central forms, N for northern forms, S for southern forms, E for eastern forms, and W for western forms. It was determined that N. nehring has 2n = 54C, NF = 74; 2n = 56N, NF = 72; 2n = 58N, NF = 74, and 2 diff erent forms of 2n = 60 (NF = 78, NF = 82) in these areas. Th is study fi lled the gaps in distribution of blind mole rat chromosomal forms around Çankırı and Çorum provinces. Th e distribution areas of 2n = 54C, 56N, 58N, and 60 forms in the area were brought to light.
