Parasites in native and introduced molluscs of the Wadden Sea
Recent research findings suggest that introduced species show a low or no parasite burden in their new habitats. This can result in an increased growth, better reproduction and consequently an advantage in competition with native species. Surveys on a local scale and investigations of other species...
