Abstract:

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. vinogradovi (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).
