Abstract The Asian brush-clawed shore crab Hemigrapsus takanoi was introduced to the northern Wadden Sea (southeastern North Sea) in 2009 and now represents one of most abundant brachyuran species. Abundance studies revealed an increase mean densities on mixed reefs native blue mussels ( Mytilus edulis ) Pacific oysters Magallana gigas from 18 individuals m −2 2011 216 2020. Despite its current high only little is known about feeding habits H. , effects prey populations associated community...
Predators can affect parasite-host interactions when directly preying on hosts or their parasites. However, predators may also have non-consumptive indirect effects adjust behaviour physiology in response to predator presence. In this study, we examined how chemical cues from a predatory marine crab the transmission of parasitic trematode its first (periwinkle) second (mussel) intermediate host. Laboratory experiments revealed that crabs lead threefold increase release cercariae periwinkles...
Abstract We studied the potential of a recently introduced species, Asian brush-clawed crab ( Hemigrapsus takanoi ), to expand its distribution range further into Baltic Sea. H. has been documented in southwestern Sea since 2014. The ability persist and Proper will depend on their sustain all stages complex life cycle, including pelagic larvae, under Sea's conditions. Range limits may be established by tolerance low salinity, which addition affected water temperature. A key question is...
Introduced bioengineering organisms may fundamentally change native coastal ecosystems by modifying existing benthic habitat structures and thereby habitat-specific species interactions. The introduction of the Pacific oyster Magallana gigas into sedimentary area south-eastern North Sea its preferred settlement on blue mussel shells caused a large-scale shift from monospecific Mytilus edulis beds to current mixed reefs mussels oysters. To investigate whether newly developed biotic affects...
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...
