A series of surveys were carried out to characterize the physical and biological parameters of the Millennium Atoll lagoon during a research expedition in April of 2009. Millennium is a remote coral atoll in the Central Pacific belonging to the Republic of Kiribati, and a member of the Southern Line Islands chain. The atoll is among the few remaining coral reef ecosystems that are relatively pristine. The lagoon is highly enclosed, and was characterized by reticulate patch and line reefs...

New research in the FASEB Journal shows how coral reefs cope with environmental stress such as 'extractive activity': Innate immunity defends the colony Much attention has been paid to the fate of wildlife living on and above the Gulf of Mexico's surface. Now, a new research study published in the June 2010 print issue of the FASEB Journal looks toward the seafloor to explain coral susceptibility to disease outbreaks when they encounter environmental stress and to set the stage for...

Field studies have shown for the first time that several common species of seaweeds in both the Pacific and Caribbean Oceans can kill corals upon contact using chemical means. While competition between seaweed and coral is just one of many factors affecting the decline of coral reefs worldwide, this chemical threat may provide a serious setback to efforts aimed at repopulating damaged reefs. Seaweeds are normally kept in check by herbivorous fish, but in many areas overfishing has reduced the...

An international team of marine biologists has found that existing diversity in some coral populations may significantly influence their response to extreme temperature disturbances "” such as those predicted from climate warming. The team demonstrated that natural selection acting on the species of algae living within corals may determine which partnerships will survive when confronted with extreme temperatures changes. The results will be published online in the May 5 issue of the...

An outbreak of a disease called Montipora White Syndrome (MWS) was found in Kaneohe Bay, OÊ»ahu within the last month prompting an interagency response team composed of scientists and students to document the extent, spread and potential causes of the disease. Members of the investigative team included scientists from the University of Hawaii at Mānoa's Hawaii Institute of Marine Biology (HIMB), USGS National Wildlife Health Center and Bishop...

Coral reefs are slowly becoming extinct and could disappear entirely within the next century -- which could have disastrous results all over the world, experts claim. According to National Oceanic and Atmospheric Administration (NOAA) statistics published in a March 25 Associated Press (AP) article, roughly 19-percent of the Earth's coral reefs have already disappeared, and an additional 15-percent could be gone within the next two decades. Furthermore, Dr. Kent Carpenter, a professor at Old...

Warming seas due to climate change have bleached large parts of the southernmost coral reef in the world, putting the reef on the edge of destruction, an Australian scientist warned on Wednesday. Peter Harrison has been monitoring the reef off Lord Howe Island since 1993, and said a rise in sea temperature of 4 degrees Fahrenheit had drained much of the reef of its striking colors. "We're hoping the vast majority of these corals will be able to recover, but at the moment this whole system...

Fossil corals, up to half a million years old, are providing fresh hope that coral reefs may be able to withstand the huge stresses imposed on them by today's human activity. Reef ecosystems were able to persist through massive environmental changes imposed by sharply falling sea levels during previous ice ages, an international scientific team has found. This provides new hope for their capacity to endure the increasing human impacts forecast for the 21st century. In the world's first study...

Australia's Great Barrier Reef (GBR) is showing an extraordinary range of benefits from the network of protected marine reserves introduced there five years ago, according to a comprehensive new study published in the Proceedings of the US National Academy of Sciences. The scientific team, a "Ëœwho's-who' of Australian coral reef scientists, describes the findings as "a globally significant demonstration of the effectiveness of large-scale networks of marine reserves". "Our data...

Penn State researchers and their international collaborators have discovered a diversity of corals harboring unusual species of symbiotic algae in the warm waters of the Andaman Sea in the northeastern Indian Ocean.  "The existence of so many novel coral symbioses thriving in a place that is too warm for most corals gives us hope that coral reefs and the ecosystems they support may persist "” at least in some places "” in the face of global warming," said the team's leader,...

Coral Reef

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...
