SEASONAL DEVELOPMENT OF ZOOPLANKTON - COMPARISON OF DIFFERENT WATER BODIES
 KOSÍK, Miroslav
Structure and seasonal dynamic of zooplankton and hydrochemical and limnological parameters were studied in different type of small water bodies. Twelve localities of shallow standing waters were selected from four varied biotopes - pools, ponds, sink, surface depression, mining potholes and larger reservoirs like flooded excavated hollow. Zooplankton was primarily determinated by external factors influencing the overall character of water ecosystem and internal factors like fish stock and content of organic matter. Zooplankton species composition exhibits distinctive differences in the individual types of localities as well as in the season. Higher species diversity was recorded in pools, mesotrofic water bodies were considered as localities with lower species diversity. Results of this observation should be useful for water locality planning and management in restoration process in post-mining landscape.
