Updating the geographical range of Terek barbel Barbus ciscaucasicus Kessler, 1877 (Cyprinidae) using the cytochrome b molecular marker

Abstract

An analysis of the mtDNA marker allowed expanding the geographical range of the Terek barbel Barbus ciscaucasicus Kessler. The new findings expand the geographic range to more than 100 km southwards down to the Pirsaat River basin in Azerbaijan. It has been suggested earlier that the Pirsaat River was inhabited by the Kura barbel Barbus cyri De Filippi. The population of the Terek barbel in the Pirsaat River is isolated genetically from the barbels of the main geographic area of this species.
