Summary

Both species studied - blue mussel (Mytilus edulis) and bladder wrack (Fucus vesiculosus) - are species with special adaptions to the conditions of the Wadden Sea. These adaptions result in a high morphological plasticity, whereby even populations of small geographic distances are represented by different ecotypes. Furthermore, these species belong to phylogenetically young groups, whose separation is too weak to define the species by morphologic data only. To compare environmental samples in the ESB, it is absolutely essential to identify target species clearly, because differences in metabolism may affect the comparability of specimen. Therefore, the aim of this study was to clarify by suitable morphologic and genetic methods, whether there are target or non-target species on the ESB sampling sites.
