Community analysis of macrofauna associated with cold-water coral reefs in the NE Atlantic (poster)
Cold-water corals are widespread ecosystems with a bathymetric distribution from 0 to 6200 m. Although these corals were first recorded in the 18th century, they only have received more attention during the past decade. These ecosystems are threatened by the increasing human exploration of the natur...

Cold-water corals are widespread ecosystems with a bathymetric distribution from 0 to 6200 m. Although these corals were first recorded in the 18th century, they only have received more attention during the past decade. These ecosystems are threatened by the increasing human exploration of the natural sources of the continental slopes. One of the best known cold-water corals is Lophelia pertusa (Linnaeus, 1758). Scientists presume that the associated fauna of this common coral would be as diverse as the fauna occurring in the tropical reefs.The purpose of this study was to analyse the macrofauna associated with Lophelia in the North-East Atlantic.
