210Pb-226Ra chronology reveals rapid growth rate of Madrepora oculata and Lophelia pertusa on world’s largest cold-water coral reef
Here we show the use of the 210Pb-226Ra excess method to determine the growth rate of two corals from the world’s largest known cold-water coral reef, Røst Reef, north of the Arctic circle off Norway. Colonies of each of the two species that build the reef, Lophelia pertusa and Madrepora oculata, were collected alive at 350 m depth using a submersible. Pb and Ra isotopes were measured along the...
متن کاملA deep-sea slant on the molecular phylogeny of the Scleractinia.
Lophelia pertusa and Madrepora oculata are azooxanthellate corals with nearly cosmopolitan distributions. They form cold-water reefs in the upper bathyal zone on continental margins and offshore banks [A.D. Rogers, Int. Rev. Hydrobiol. 84 (1999) 315]. Lophelia is classified in the family Caryophylliidae and Madrepora in the family Oculinidae, both on the basis of skeletal morphology. Recent mol...
متن کاملFirst observations of the cold-water coral Lophelia pertusa in mid-Atlantic canyons of the USA
The structure-forming, cold-water coral Lophelia pertusa is widely distributed throughout the North Atlantic Ocean and also occurs in the South Atlantic, North Pacific and Indian oceans. This species has formed extensive reefs, chiefly in deep water, along the continental margins of Europe and the United States, particularly off the southeastern U.S. coastline and in the Gulf of Mexico. There w...
متن کاملTrawling damage to Northeast Atlantic ancient coral reefs.
This contribution documents widespread trawling damage to cold-water coral reefs at 840-1300 m depth along the West Ireland continental shelf break and at 200 m off West Norway. These reefs are spectacular but poorly known. By-catches from commercial trawls for deep-water fish off West Ireland included large pieces (up to 1 m(2)) of coral that had been broken from reefs and a diverse array of c...
متن کاملSpatial Scales of Bacterial Diversity in Cold-Water Coral Reef Ecosystems
BACKGROUND Cold-water coral reef ecosystems are recognized as biodiversity hotspots in the deep sea, but insights into their associated bacterial communities are still limited. Deciphering principle patterns of bacterial community variation over multiple spatial scales may however prove critical for a better understanding of factors contributing to cold-water coral reef stability and functionin...
