THE INFLUENCE OF THE ECOTONE DIVERSITY ON THE ORNITHO- COMPLEXES OF THE AZOV-BLACK SEA COAST OF UKRAINE

摘要

The importance of birds on the Azov-Black Sea coast as indicators of the environment quality depends on a lot of reasons. As active components of ecosystem, birds complete or form (determine) many feeding sections not only in separate biogeocenosis but also outside their areas. Birds quickly react to changes of any ecosystem parameters. Besides they play an important part in the economic activity of man. The problem of bird genofond protection has lately become a part of many international programmes and agreements.
