Native parasites adopt introduced bivalves of the North Sea
Abstract - Introduced species may have a competitive advantage over native species due to a lack of predators or pathogens. In the North Sea region, it has been assumed that no metazoan parasites are to be found in marine introduced species. In an attempt to test this assumption, we found native par...

Future studies should consider these implications to arrive at a better understanding of the interplay between native parasites and introduced hosts.
