Morphological assessment of the North Eurasian interspecific hybrid forms of the genus Bythotrephes Leydig, 1860 (Crustacea: Cladocera: Cercopagididae)
The North Eurasian interspecific hybrid forms of the genus Bythotrephes Leydig, 1860 are described morphologically in detail with consideration of the previous data on their allozyme analysis and brief morphological examination. In total, three hybrid forms have been encountered, among which B. brev...
