- Аннотация: The species, spatial and trophic structure of the littoral macrobenthos of the Lapshaginsky estuary was studied and analyzed. The study revealed a trend of increasing the total density, biomass and species diversity of the macrobenthos community as the salinity of water increases - from the brackish-water areas of the estuary to the marine waters. The total density, biomass and species diversity also also increased as the mareographic level decreases - from the upper to the middle and lower horizons of the littoral. The brackish area is mostly dominated by oligomix communities of small brackish and marine euryhaline species of collecting detritophages Hydrobia ulvae , Tubificoides benedii and to a lesser extent by mobile sestonophages Mya arenaria . The marine region is dominated by polymix communities of less euryhaline marine species of immobile sestonophages Mytilus edulis and to a lesser extent, by the detritus collecting feeders Macoma balthica and scrapers Littorina saxatilis . Hydrobia ulvae , Tubificoides benedii and Littorina saxatilis mainly prevailed in the upper and middle littoral zones, while Mya arenaria , Mytilus edulis and Macoma balthica - in the middle and lower horizon of the tidal strip.
