We have studied the distribution of littoral meiobenthos in the Lunkulansaari area (eastern Ladoga) using the polygon method (polygon size 300x300 m) and diving research. Main characteristics of this area were: the wide shallow area and a high species richness of macrophytes. We have produced the maps of the distribution of total meiobenthos and dominant species according to the depth, location, aquatic vegetation, detritus and small fractions of bottom ground, varying according to the distance from the shore. The maximum abundance and biomass of community were noted at the shoreline where the Iris pseudocorus grow, primarily due to the numbers of oligochaetes and in the open coastal areas with detrital litter, dominated by chironomids. In the areas occupied by the Polygonum amphibium and by the Phragmites australis subpurum quantitative characteristics were loweras well as in the area of open water behind the P. australis subpurum . The species richness gradually decreased as the distance from the shore was increasing. We have shown the change ofspecies with different ecological preferences along the studied profile. The research emphasises the advantage and informative value of the method that has been used for a full study of the meiobenthos.
