Neobiota as hosts in parasitic life cycles trematodes in intertidal molluscs of the North Sea
Neobiota may have a competitive advantage over native species due to a lack of enemies as predators or pathogens. In the North Sea region, it has been assumed that no parasites are to be found in marine introduced species. In an attempt to test this assumption, we investigated introduced molluscs fo...
