Abstract
    Water movements are ecologically more significant in the western Baltic Sea than on tidal rocky shores of more temperate and colder oceans. In these latter areas this factor is present mainly as surf and tides, and this has led to the definitions of habitats as exposed to surf or protected from it (i.e. sheltered).The western Baltic, on the other hand, can be described as typical of marine, non-tidal, areas which have irregular fluctuations in the water level caused by differing weather conditions, unstable hydrographic conditions, and particular conditions of the substrate (in this case a geologically young sea with a level beach and a gravel substrate).In the western Baltic the water movements are a direct result of the wind and the fluctuations in water level, of oscillations in the whole or a part of the Baltic Sea system caused by weather conditions, and of water-exchange processes. These water movements have a profound effect upon the benthic vegetation. The substrate tends to shift and thus makes the vegetation structure unstable. Other factors involved are the irregular emersion of the littoral region and the resistance to the stresses imposed on the constituent species by rapid changes in hydrographic conditions, particularly in salinity.
