Variation of nucleolar organizer regions in two 2n=48 chromosomal forms of nannospalax nehringi (Satunin, 1898) (Rodentia: Spalacidae) from North-eastern Anatolia. Acta Zoologica Bulgarica, 70(3), 305-308.0324-0770https://hdl.handle.net/11468/5216http://www.acta-zoologica-bulgarica.eu/downloads/acta-zoologica-bulgarica/2018/70-3-305-308.pdfWe describe the Ag-NOR distribution in two 2n=48 populations of blind mole rats of the genus Nannospalax from two localities (Çaldıran and Aşağısutaşlı) in the Van and Iğdır Provinces in North-eastern Anatolia, Turkey. The karyotypes of the studied populations differed in the proportion of biarmed and acrocentric autosomes (NFa=64 and 68, respectively). The nucleolar organizer regions (NORs) occurred on four autosomal pairs in the Van population whereas only three NOR-bearing autosomal pairs were detected in the Iğdır population. The karyotype of the individuals from the Iğdır population was similar to the previously studied population from the Van-Erciş Province. This similarity indicated that geographical barriers did not limit dispersal of the cytotype with NFa=68 chromosomal form in North-eastern Anatolia.eninfo:eu-repo/semantics/openAccessAttribution-NonCommercial-NoDerivs 3.0 United StatesSpalacidaeNannospalax nehringiAg-NOR bandingEastern AnatoliaArticle703305308WOS:000446807800004Q4
