Microbial abundance in the coelenteron and mucus of the cold-water coral Lophelia pertusa and in bottom water of the reef environment
International audience Microorganisms play an important role in coral ecology; however, little is known about cold-water coral (CWC) reefs. Microbial abundance in bottom water of Lophelia pertusa-dominated CWC reefs in the Skagerrak, North Sea, was elevated by ca. 40% for prokaryotes and 70 to 90% f...
