| Summary: | The investigation is carried out at the Marine Biological Station of Saint-Petersburg State University (Keretsky archipelago, White Sea, Russia). The influence of granulometrical compound of sediments and presence of oxygen on the structure of bottom communities are investigated. The part of sessile organisms and suspension feeders in total biomass of the zoobenthos is positively correlated with percentage of pebble (0>1O mm). These groups are also correlated with presence of oxygen. We show that granulometrical compound of sediments influences both parity of ecological groups of benthos and the number of species. |
