Zooplankton species composition in the dumping area of the Southeastern part of the Baltic Sea
This article analyses the zooplankton species composition and species structure in the dumping area. The research was carried out in spring and summer of 1998—2009. Rotifera‚ Copepoda and Cladocera groups of zooplankton were studied. Certain changes to the zooplankton species ...
Peculiarities of zooplankton succession depending on the landscape and the genesis of the lake basin (on ex-ample of some lakes of the Pskov Oblast)
On the basis of 1948—2011 materials, this article characterises the zooplankton of three large lakes of similar age and origin found at different trophic stages and in different landscapes of the Pskov region. It is shown that the structural features of the organization and direction of succession of zooplankton communities ...
Long-term distribution of the crustacean Calanoida (Copepoda) in the dumping area in the South East Baltic
... summer of 1998—2009 in the framework of national monitoring. The species composition of the Calanoida group was identified as well as the variations in their abundance and biomass. A seasonal (spring – summer) increase in the abundance and biomass of zooplankton and Calanoida was observed. The seasonal increase took place against the background of a steady decrease in the abundance abundance and biomass of crustacean throughout the period (1998—2009).

Seasonal Larva Number Dynamics and Settlement of Juvenile Zebra Mussel (Dreissena polymorpha Pallas) in the Prybrezhny Quarry (the Kaliningrad region)
... region). In 2002, zebra mussel larvae were found in plankton from the second part of July till the end of August. The peaks of abundance were registered in the middle of July and in the beginning of August. The larvae accounted for 33% of the total zooplankton abundance. The size of larvae varied from 100 to 375 μm. The beginning of the juvenile settlement was observed in July. Colony mud accumulation is considered having a negative effect on successful settlement and survival of juveniles.
