abstract: Absorbing Hybridization of Cobitis taenia and Sabanejewia aurata (Cypriniformes, Cobitidae)
in Water Reservoirs of Northern Ukraine Connected with Diploid-Polyploid Complex Formation.
Mezhzherin, S. V., Pukhtayevych, P. P., Tsyba, А. А. — In the rivers of the Northern Ukraine by meams
of karyological and allozyme analysys obtained extensive natural hybridization between Cobitis taenia
and Sabanejewia aurata, initially leading to the formation of diploid hybrids. Besides that certain water
bodies are predominantly populated by triploids of the C. taenia — C. tanaitica — S. aurata biotypes.
Since the share of this kind of hybrid biotypes signifi cantly exceeds the number of individuals of S. aurata,
it is concluded that the hybridization of a common and eurybiontic C. taenia with rarer stenobiontic
S. aurata, is of absorbing character.
