Struktura zbiorowisk fitoplanktonu w strefie szuwaru i pelagialu w Jeziorze Budzynskim
The research of the qualitative and quantitative phytoplankton structure of the rush
and open water zones of two basins of the Budzynskie Lake differing in the presence of submerged
macrophytes was conducted. A greater variety of phytoplankton species was present in
the overgrow basin, as a result of enrichment of the zone of open water above submerged macrophytes
by periphyton taxa. In the same basin the reduction of phytoplankton taxa numbers and
biomass appeared, that can be connected with pressure of zooplankton grazing and with repressing
influence of macrophytes
