abstract:
In 1996-1998, the photosynthetic activity of psammic and plankton algae communities of the eulittoral was studied in the near-shore zone of Lake Piaseczno (Łęczna-Włodawa Lakeland, Eastern Poland). Based on the C:N:P weight ratio in the process of photosynthesis, the quantities of carbon, nitrogen and phosphorus consumed by phytopsammon and phytoplankton communities during 1 day were calculated. The eupsammon had the highest count of assimilated carbon (from 791.5 in the spring to 1411.7 mg C m-2 day-1 in the summer), nitrogen (130.1 in the spring and 232.5 mg N×m-2×day-1 in the summer) and phosphorus (17.9 in the spring and 31.9 mg P m-2 day-1 in the summer). The lowest quantities of assimilated elements were recorded in the psammolitoral phytoplankton.
