PECULIARITIES OF THE MORPHOLOGY AND LIFE CYCLESOF MESOCYCLOPS LEUCKARTI (CLAUS 1857) FROM WATER BODIESOF EASTERN SIBERIA
Females of Mesocyclops leuckarti (Сlaus 1857) inhabiting Lake Baikal (Maloe More Strait) and Lake Gusinoe, Zabaikalye (=Transbaikalia) are redescribed. Peculiar features of the species' life cycle are due to the anthropogenic impact on the hydrological conditions and the stage of the development (ageing) of the water body.
