| In experiments in the western Baltic Sea (Kiel, Germany), manipulations of A. improvisus and the Blue Mussel Mytilus edulis, showed that M. edulis outcompeted and replaced A. improvisus. However, when some mussels were removed, to simulate predation, the two species coexisted and out-competed other fouling community species. Amphibalanus improvisus thus has a sub-dominant role in the fouling community of the Western Baltic (Dürr and Wahl 2004). | ||
