[Genetic structure of species complex of the spined loach Cobitis auc. (Cypriniformes: Cobitidae) in Severskiĭ Donets river basin].
Biochemical, genetic, cytometric and morphological analyses of spined loaches of the middle stream of Severskiy Donetz river revealed 3 bisexual species: Cobitis taenia s.l. (68% of the sample); C. melanoleuca (11%); Sabanejewia aurata (9%) and 2 hybrid forms: triploid C. taenia(2)-sp. (9%) and diploid C. taenia-melanoleuca (3%). Distinctive features of genetic structure of polyploid hybrids C. taenia(2)-sp. as well as taxonomic identity of diploid C. taenia s.l. of Severskiy Donetz river were discussed in regard to the Dnieper population ones.
