Comparative research on food web structure has revealed generalities in trophic organization, produced simple models, and allowed assessment of robustness to species loss. These studies have mostly focused on free-living species. Recent research has suggested that inclusion of parasites alters structure. We assess whether such changes in network structure(More)
Dense beds of mussels of the family Mytilidae occur worldwide on soft-bottoms in cold and warm temperate coastal waters and have usually been considered hot spots of biodiversity. We examined intertidal mussel beds at four distant locations around the globe with the same sampling method, to Wnd out whether this " hot spot " designation holds universally. We(More)
This data set presents a food web for the Sylt tidal basin, an intertidal ecosystem in Germany and Denmark. The intertidal part of this bight consists of extensive tidal flats with the main habitats being lugworm sandflats, seagrass meadows, and mixed mussel and oyster beds. This food web has three noteworthy attributes: (1) high resolution of free-living(More)
Invading alien species may have to await appropriate conditions before developing from a rare addition to the recipient community to a dominance over native species. Such a retarded invasion seems to have happened with the antipodean cirripede crustacean Austrominius modestus Darwin, formerly known as Elminius modestus, at its northern range in Europe due(More)

Genotypic structure and temporal dynamics of the dwarf seagrass, Zostera noltii, were studied in an intertidal meadow that has persisted since prior to 1936 near the Wadden Sea island of Sylt. Samples were collected from two 10 9 10 m plots separated by 250 m from All the samples were gen-otyped with nine microsatellite loci. No genotypes were shared(More)
We reconstruct past accretion rates of a salt marsh on the island of Sylt, Germany, using measurements of the radioisotopes 210 Pb and 137 Cs, as well as historical aerial photographs. Results from three cores indicate accretion rates varying between 1 and 16 mm year −1. Comparisons with tide gauge data show that high accretion rates during the 1980s and(More)
The scale of human pressures on marine ecosystems gradually increased from local to global effects during the last centuries. Global warming, sea level rise and trans-oceanic spread of alien species are now or will be major drivers of ecological change in the Wadden Sea. Eutrophication may rank as a super-regional effect as the organic matter turnover in(More)
The Wadden Sea is one of the largest intertidal areas in the world and has been designated as a UNESCO World Heritage Site in recognition of its unique natural features. Major changes in the morphology and ecology of the Wadden Sea over the past millennium resulted from increasing anthropogenic influences such as coastal protection, land claim from the sea(More)
