Wadden Sea mussel beds invaded by oysters and slipper limpets: competition or climate control?
Introduced species are often considered to be a threat to residents, but not all reciprocal trends may reflect species interaction. In the northern German Wadden Sea, native mussel Mytilus edulisExpand
Too cold to prosper—winter mortality prevents population increase of the introduced American slipper limpet Crepidula fornicata in northern Europe
The distribution of the introduced American slipper limpet Crepidula fornicata (L.) on the Atlantic coast of Europe shows a clear latitudinal gradient. In the south, C. fornicata may reach abundancesExpand

Mya arenaria currently occupies a wide geographical range in the northern hemisphere, on both coasts of the Atlantic as well as on the Pacific east coast. Some authors claim it also occurs on theExpand
Mytilid mussels: global habitat engineers in coastal sediments
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 examinedExpand
Recolonization pattern of the polychaete Lanice conchilega on an intertidal sand flat following the severe winter of 1995/96
Abstract. The recolonization process of Lanice conchilega was studied on an intertidal sand flat in the northern Wadden Sea after an intertidal population had been wiped out during the severe winterExpand
Reduced epibenthic predation on intertidal bivalves after a severe winter in the European Wadden Sea
One hypothesis to explain the phenomenon of high bivalve recruitment after severe winters in coastal North Sea sediments is reduced epibenthic predation. Using predator exclusion ex- periments, IExpand
Marine metapopulations: a useful concept?
Abstract. We discuss the potential and limitations of the metapopulation concept in marine ecology. The usefulness of the concept in terrestrial ecology is neither based on its simplicity orExpand
Differential effects of the severe winter of 1995/96 on the intertidal bivalves Mytilus edulis, Cerastoderma edule and Mya arenaria in the Northern Wadden Sea
Abstract. Intertidal mussel beds were severely damaged by scouring ice floes during the winter of 1995/96. Aerial surveys before and after the winter showed that more clusters of mussel beds vanishedExpand
How predictable is high bivalve recruitment in the Wadden Sea after a severe winter
Higher than average recruitment among bivalves on the intertidal flats of the Wadden Sea was observed many times after severe winters in the period 1940 - 1995. The occurrence of another severeExpand
Juvenile-adult distribution of the bivalve Mya arenaria on intertidal flats in the Wadden Sea: why are there so few year classes?
Abstract Patchy distribution is frequently observed in benthic marine invertebrates. In order to indentify factors causing spatial patterns in the bivalve Mya arenaria, abundances of juveniles andExpand
