Exploring the cold-water coral holobiont: characterizing the bacterial associates of the octocorals Paragorgia arborea and Primnoa resedaeformis
Corals are among the world’s most biodiverse symbiotic ecosystems, and recent work has highlighted the importance of microbes to the health and resilience of reef-building tropical corals. Cold-water corals (CWCs) constitute crucial ecosystems in both shallow and deeper waters, and also form symbios...
