A new study of the world's shrinking marine habitats suggests that a large decline in shellfish populations could be having a disastrous effect on already vulnerable ecosystems. In the study, published by The Nature Conservancy, researchers warned that some 85 percent of the planet's oyster reefs have already disappeared and that many of those remaining are now "functionally extinct." The report, which experts in the field have called the first global assessment of its kind, claims that...

Better coral reef assessment and management are needed if the reefs are to survive global warming, a conservation group said Wednesday in Washington. The International Union for Conservation of Nature and Natural Resources made the statement in releasing a report Resilience Assessment of Coral Reefs. We already know that climate change is destroying coral reefs through warming waters that cause coral bleaching and through acidifying oceans that hinders coral skeleton growth, Garriel...

Experts say that more than half of the world's coral reefs could disappear in the next 50 years, in large part because of higher ocean temperatures caused by climate change. But now Stanford University scientists have found evidence that some coral reefs are adapting and may actually survive global warming. "Corals are certainly threatened by environmental change, but this research has really sparked the notion that corals may be tougher than we thought," said Stephen Palumbi, a professor of...

A new study appearing in Restoration Ecology describes a novel technique for reattaching large sponges that have been dislodged from coral reefs. The findings could be generally applied to the restoration of other large sponge species removed by human activities or storm events. 20 specimens of the Caribbean giant barrel sponge were removed and reattached at Conch Reef off of Key Largo, Florida in 2004 and 2005 at depths of 15m and 30m. The sponges were affixed to the reef using sponge...

Scientists reported Thursday that a section of Australia's Great Barrier Reef - in danger of being killed by global warming within mere decades - has regenerated itself in record time. This partial regeneration is perhaps more appropriately being referred to as a mere "lucky escape" by the head of research for the authority that preserves the World Heritage-listed reef, Laurence McCook. Due to global warming, this expanse of badly damaged coral at Keppel Island began experiencing an increase...

WASHINGTON, April 22 /PRNewswire-USNewswire/ -- The following is a statement from SeaWeb's Too Precious To Wear Campaign:   Members of the Too Precious To Wear coral conservation campaign, including SeaWeb, Tiffany & Co. and Leber Jeweler Inc., commend the U.S. House of Representatives' Committee on Natural Resources for passing the reauthorization of the Coral Reef Conservation Act (H.R. 860) out of committee today. The vote, coinciding with Earth Day, signifies a renewed sense of...

Divers below the waves of Sekisei Lagoon, Japan are hard at work with compressed air drills in hand and hopes of bringing new life to Japan's largest coral reef near the southern end of the Okinawa chain of islands. With revolutionary new technology and a substantial amount of taxpayer money, the Japanese government is hoping to combat what has been previously reported to be a 90 percent reduction of coral around Okinawa's islands, according to the New York Times. Marine biologists told the...

Expedition's Findings Will Provide Baseline Study of Unique Offshore Coral Reefs LANDOVER, Md., March 25 /PRNewswire-USNewswire/ -- The final expedition of a four-year collaborative coral reef research program along the Red Sea coast of Saudi Arabia will occur April 4-28, 2009, in an area known as the Farasan Banks. The expedition will be conducted through a partnership among Khaled bin Sultan Living Oceans Foundation, the National Commission for Wildlife Conservation and Development [of...

Scientists identified seven new species of bamboo coral discovered on a NOAA-funded mission in the deep waters of the Papahānaumokuākea Marine National Monument. Six of these species may represent entirely new genera, a remarkable feat given the broad classification a genus represents. A genus is a major category in the classification of organisms, ranking above a species and below a family. Scientists expect to identify more new species as...

The evolutionary tendency of corals to alter their skeletal structure makes it difficult to assign them to different species. Researchers writing in the open access journal BMC Evolutionary Biology have used genetic markers to examine coral groupings and investigate how these markers relate to alterations in shape, in the process discovering that our inaccurate picture of coral species is compromising our ability to conserve coral reefs. Zac Forsman led a team of researchers from University...

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...
