THE ROLE OF ZEBRA MUSSEL (<i>DREISSENA POLYMORPHA </i>PALLAS) IN NAROCH LAKES FUNCTIONING (LITERATURE REVIEW)
The ecosystem of Naroch lakes (Belarus) is the object of hydroecological observations for a long time. The invasion of mollusc Dreissena polymorpha Pallas occurred in the middle of 1980th. The article provides the literature review on the invasive species population dynamics, the influence on the aboriginal zoobenthos structure and edifier ability of the mollusc. It was evaluated the impact of Dreissena in the cycle of suspended and organic matter and nutrients as well as early sediments diagenesis. The materials extend the statements and concept on benthification as one of the stage of the modern evolution of lake ecosystems.
