Changes of the benthic Microcystis community during the time of reinvasion and its influence on the planktonic inoculum were investigated in a laboratory experiment and in a shallow lake (Quitzdorf Reservoir, Germany). Reinvasion was quantified by the diminution of benthic Microcystis abundance, and moreover, by the increase of Microcystis in the water column. Laboratory investigations revealed that...
It is generally agreed that the hepatotoxic microcystins (MCs) are the most abundant toxins produced by cyanobacteria in freshwater. In various freshwater lakes in East Africa MC-producing Microcystis has been reported to dominate the phytoplankton, however the regulation of MC production is poorly understood. From May 2007 to April 2008 the Microcystis abundance, the absolute and relative abundance...
