摘要: An experimental disposal of dredged material was performed in June 2001 at two adjacent sites Mecklenburg Bay (western Baltic Sea) to investigate the impacts on a sublittoral fauna community (macrozoobenthos). Temporal changes parameters were analysed: Total abundance and multidimensional scaling (MDS) ordination results showed that causes significant benthic assemblages comparison original situation before activities. The bivalves Arctica islandica Macoma balthica almost not affected by disposal. Abundances polychaete N. hombergii as well epibenthic cumacean D. rathkei decreased factor 1.4-3.9 whereas most other invertebrates suffered even more. Two years after high level recovery found, but also change dominance structure. These are rather due inter-annual variability regional recruitment processes than
