The karyotypes of some rodent species (Mammalia: Rodentia) from Eastern Turkey and Northern Iran with a new record, Microtus schidlovskii Argyropulo, 1933, from Eastern Turkey

During a field excursion in eastern Turkey and the Zanjan province of Iran, 9 rodent species were captured, and the diploid number of chromosomes (2n), the number of autosomal arms (FNa) and the fundamental number (FN) were determined for these species. Microtus schidlovskii with 2n = 60 and FNa = 58 was recorded for the first time from Özalp (Van) and Yüksekova (Hakkari). The karyological record of Meriones vinogradovi in Turkey was also given for the first time. The karyological results were determined as follows: Spermophilus xanthophrymnus (2n = 42, FNa = 78, FN = 82 in Turkey), Mesocricetus brandti (2n = 42, FNa = 78, FN = 82 in Iran), Microtus socialis (2n = 62, FNa = 60 FN = 62 in Iran, 2n = 60, FNa = 58 FN = 60 in Turkey), Meriones tristrami (2n = 72, FNa = 78, FN = 80 in Iran, 2n = 72, FNa = 82, FN = 84 in Turkey), M. inogradovi (2n = 44, FNa = 74, FN = 77 in Turkey), Meriones libycus (2n = 44, FNa = 76, FN = 80 in Iran), Apodemus iconicus (2n = 48, FNa = 46, FN = 48 in Iran), and Mus domesticus (2n = 40, FNa = 38, FN = 40 in Iran and Turkey). Türkiye'nin doğusunda ve İran'ın Zanjan şehri civarında yapılan arazi çalışmasında, 9 kemirici türü yakalandı ve bu türlere ait diploid kromozom sayıları (2n), otozsomal Kromozomların kol sayıları (FNa) ve kromozom kol sayıları (FN) belirlendi. 2n = 60, FNa = 58 karyolojik değerlere sahip Microtus schidlovskii Özalp (Van) ve Yüksekova'dan (Hakkari) ilk kez kaydedildi. Çalışılan türlerden Meriones vinogradovi'nin karyolojik bulguları Türkiye'den ilk kez bu çalışmayla verildi. Karyolojik çalışmalarda; Spermophilus xanthophrymnus (Türkiye; 2n = 42, FNa = 78, FN = 82), Mesocricetus brandti (İran; 2n = 42, FNa = 78, FN = 82), Microtus socialis (İran; 2n = 62, FNa = 60 FN = 62, Türkiye; 2n = 60, FNa = 58 FN = 60), Meriones tristrami (İran; 2n = 72, FNa = 78, FN = 80, Türkiye; 2n = 72, FNa = 82, FN = 84), M. vinogradovi (Türkiye; 2n = 44, FNa = 74, FN = 77), Meriones libycus (İran; 2n = 44, FNa = 76, FN = 80), Apodemus iconicus (İran; 2n = 48, FNa = 46, FN = 48), Mus domesticus (İran ve Türkiye; 2n = 40, FNa = 38, FN = 40) karyolojik değerlere sahip olduğu saptandı.
