The relative effect of physical disturbance, isolation and keymacrozoobenthic species on community development and sedimentationprocesses were studied in an in situ factorial field mesocosmexperiment in Mechandising/Display Refrigerators the northern Baltic Sea.Differences in abundanceand biomass structure of recolonising invertebrates were dueto exposure and isolation.The initial invertebrate Makeup Wipes communitieshad a negligible effect on the final communities.

However, theorganic matter content of the sediment in isolated cages increasedwith the initial number of invertebrate species.The main conclusionof the study: physically driven fluxes override the effects ofbiological interactions in shallow water systems of the northernBaltic Sea.
