Initial succession ofzooplankton and zoobenthos assemblages in newly formed quarry Lake Medard (Sokolov, Czech Republic)

摘要

This paper gives the results of the initial observation period of the development of zooplankton and zoobenthos during flooding of the residual brown coal mine pit Medard. Changes in the quantity and quality of water, flowing from different sources, and development of stratification in the lake water affect the composition ofzooplankton and zoobenthos. Original sources ofzooplankton inoculum, which are the reservoirs in the Lake Medard own catchment area, are monitored too. Another important source, that will significantly affect the formation of the newly formed lake, is the river Ohfe (Eger), which will contribute with the greatest volume of water. At the same time, the hydrochemical water quality parameters and their influence on the formation of zooplankton and zoobentos communities are monitored.
