Zooplankton of the channel zone of reservoirs of the arid zone: effects of level regime and meteorological conditions

In the channel areas of the large Tayshir Reservoir valley, zooplankton is unevenly distributed along the longitudinal profile. The number and biomass of communities increases from the upper to lower rea ches. In the Durgun Reservoir, which has features of a canyontype reservoir, the greatest abun...
