Phytopsammon and phytoplankton of land/water ecotone of mesotrophic lake in the Polesie region (Eastern Poland)

183-194

In the years 1996-1997 (in July and September) a species composition as well as a productivity of phytopsammon (eupsammon and hydropsammon) and phytoplankton were investigated in a land/water ecotone of mesotrophic lake. The phytopsammon was characterized by a higher number of species and higher algae abundance than that of phytoplankton. The highest values of gross primary production and chlorophyll a concentration were obtained for eupsammon, while the lowest ones were obtained for phytoplankton. A big similarity of eupsammon and hydropsammon and a considerable diversity between eupsammon and phytoplankton was proved.
