A team of researchers from the Georgia Institute of Technology is using the Aquarius underwater laboratory off the coast of Florida to study how the diversity of seaweed-eating fish affects endangered coral reefs.
New evidence of sea-level oscillations during a warm period that started about 125,000 years ago raises the possibility of a similar scenario if the planet continues its more recent warming trend.
Since the beginning of the Industrial Revolution, the concentration of carbon dioxide in the atmosphere has been rising due to the burning of fossil fuels.
The record-breaking cold weather experienced in Florida last year resulted in large losses among coral reef species.
TAU researcher discovers that endangered soft corals are also building blocks of coral reefs.
Wildlife Conservation Society leads global assessment showing where climate stresses on reef systems will be and places to focus management.
Last month, NOAA scientists used acoustic sonar to map several areas of the outer continental shelf edge off the coast of Florida.
Climate change and acidifying ocean water are likely to have a highly variable impact on the worldâ€™s coral reefs, in space, time and diversity, international coral scientists cautioned recently.
Australian scientists today announced they have sequenced the genome of the staghorn coral Acropora millepora, a major component of the Great Barrier Reef and coral reefs worldwide.
Coral reefs are submerged structures consisting of calcium carbonate secreted by corals. Coral reefs are colonies of small animals found in marine waters that enclose few nutrients. The majority of coral reefs are constructed from stony corals, which then consist of polyps that come together in groups. The polyps are like small sea anemones, to which they are very closely related. Unlike the sea anemones, coral polyps secrete hard carbonate exoskeletons which provide support and protections...
Chalice Corals, are a family of stony corals in the Pectiniidae family. Members of this family are mostly colonial but at least one species, Echinomorpha nishihirai, is solitary. These corals are endemic to the Indian and Pacific oceans. Pectiniids have a number of different forms but are basically streamlined and smooth. Polyps are large and brightly colored and resemble those of members of the Mussidae family of corals. The polyps are only extended at night. Tentacles are translucent,...
Siderastreidae is a family of colonial, reef building stony corals. Members of this family include symbiotic algae in their tissues which help provide their energy requirements. The World Register of Marine Species lists 7 genera within this family: Anomastraea, Coscinaraea, Craterastrea, Horastrea, Psammocora, Pseudosiderastrea, and Siderastrea. Corals in this family vary in form and include massive, thickly encrusting, columnar, and irregular forms. Corallites are linked by flowing...
Horn corals, known as Rugosa or Tetracoralla, are an extinct order of coral that were abundant during the Middle Ordovician to Late Permian stages. They were known as horn corals because of a unique horn-shaped chamber with a wrinkled (rugose) wall. These mostly solitary corals often reached lengths of nearly 40 inches. However, some species could form large colonies. Rugose corals have a skeleton made up of calcite that is often fossilized. Like modern corals, rugose corals were...
Tabulata is a family of extinct tabulate corals. These corals lived entirely during the Paleozoic era, being found from the Ordovician to the Permian stages. There are about 300 known genera of tabulate corals, of which Aulopora, Favosites, Halysites, Heliolites, Pleurodictyum, Sarcinula and Syringopora are the most common in the fossil record. These corals were mostly found in the shallow waters of the Silurian and Devonian, after which, they became much less common. They became extinct...
