Abstract:
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. |
