چکیده
Abstract The introduction of Pacific oysters to the sedimentary south-eastern North Sea coast and their establishment on intertidal native blue mussel beds has caused development mixed reefs mussels with extensive tidepools. Tidepools have been intensively studied at rocky shores where they show community structures, which usually differ from that surrounding emerging substrates. coasts, however, received less attention. We compared structure species interactions inside outside tidepools in oyster by determining densities snails, barnacles amphipods. Snail were similar Barnacle coverage bivalve shells, was lower tidepools, may be higher predation pressure increased snail grazing under permanently submerged conditions, as revealed field laboratory experiments. Additionally, we occurrence copepod trematode parasites Prevalence intensity parasitic copepods Trematode parasites, contrast, showed a This can explained high amphipod found because larvae represent food source Our study suggests within is not equivalent reefs. As counterparts shores, own distribution patterns particular only provide refuge for specific such copepods.
