Chromosomal characteristics of water voles (Arvicola amphibius) were studied in ten populations including 33 samples from Anatolia, Turkey. The C-banding pattern and NORs distribution were analysed in four samples from Eastern Anatolia. The conventionally stained karyotypes showed the standard complement of the species (2n = 36, NFa = 60-62, NF = 64-66). Variation in the number of autosomal arms originated from the alternative presence of a subtelocentric or an acrocentric autosomal pair. C-banding provided further support for differentiation of the amount and distribution of C-heterochromatin between populations from Central Europe and Asia Minor. Chromosomal variation among Turkish populations was manifested by the number of autosomal arms, positive C-bands and NOR-carrying autosomes.
