Structure of submerged littoral vegetation
An attempt was undertaken to compare pelagic indices commonly used to describe trophic status of lakes (SD, chlorophyll, total phosphorus and total nitrogen) with parameters characterising submerged littoral zone of lakes (maximum depth of plant occurrence, number of species, mean plant biomass and percentage biomass of the dominating species). The data were collected from 20 lakes of various morphometry and trophic state selected from the Great Masurian Lakes system (north-eastern Poland) from 1985 till 1995. The greatest impact on submerged littoral structure (species abundance and diversity) was exerted by water transparency, nutrient concentrations had negligible effect on littoral parameters. From among four littoral characteristics, submerged plant biomass seems to be of the poorest indicative value since its correlation with pelagic indices was usually weakest and statistically insignificant.
