The key to preserving the extraordinary richness and beauty of the world's coral reefs through the coming period of fragmentation caused by climate change lies in a better understanding of how newborn coral larvae disperse across the oceans to settle and grow on new reefs. Research by scientists at the ARC Centre of Excellence for Coral Reef Studies is throwing new light on the survival and settlement rates of larvae from different coral species, as a basis for predicting how fast coral...

Wildlife Conservation Society confirms sea urchins destroy reef building algae in overfished sites on Kenya's coast An 18-year study of Kenya's coral reefs by the Wildlife Conservation Society and the University of California at Santa Cruz has found that overfished reef systems have more sea urchins"”organisms that in turn eat coral algae that build tropical reef systems. By contrast, reef systems closed to fishing have fewer sea urchins"”the result of predatory fish keeping...

Officials at the National Oceanic and Atmospheric Administration (NOAA) are vowing to protect newly located coral reefs found in a 12 mile span off the southwestern coast of Puerto Rico, hoping that their discovery could lead to the revitalization of the area's coral ecosystem. The new reefs, located at depths of between 100 and 500 feet, were discovered by Richard Appledoorn, a professor at the University of Puerto Rico, and divers participating in a one-year training course, according to...

The Edge Coral Reefs project announced this week that it has identified 10 of the most at-risk coral species for protection. Conservationists have unveiled plans to preserve and protect the world's most important species of coral, helping to fight increasing threats that they say will lead to the species being "functional extinct" within decades. Scientists at the Zoological Society of London (ZSL) lead the project, which has identified 10 coral species in most urgent risk of becoming...

An expert said Wednesday that Australia's spectacular Great Barrier Reef is under threat from massive floods swamping the country's northeast, which are pouring harmful debris and sediment into the sea. Michelle Devlin said that the full impact of the floods is not yet known, but the influx will stress the colorful corals. "This does impact on the reef. It just impacts on the reef's resilience so you get very stressed corals, you get stressed sea grass," Devlin, a researcher at James Cook...

Coral reef ecosystems are one of the most diverse habitats on the planet, providing habitat for a wide variety of marine animals. Unfortunately, coral reefs and their associated fish, algae, and invertebrate species are in worldwide decline. In 2009, 83 rare corals were petitioned to be listed under the United States Endangered Species Act. The National Oceanic and Atmospheric Administration (NOAA) National Marine Fisheries Service is currently reviewing the status of the coral on the...

Unseasonal warm temperatures caused by El Niño have a profound effect on the fish populations of coral reefs in the South Pacific, scientists have found. An international team of biologists studied the arrival of young fish to the atoll of Rangiroa in French Polynesia for four years and compared their results with satellite and oceanographic data. They found that the El Niño event caused a sudden collapse in the plankton community and this led to a...

ASU study of endolithic cyanobacteria has implications for coral reefs and mussel aquaculture Geo-microbiologists from Arizona State University have solved a long-standing conundrum about how some photosynthetic microorganisms, endolithic cyanobacteria, bore their way into limestone, sand grains, mussel shells, coral skeletons and other substrates composed of carbonate. According to the lead investigator, ASU professor Ferran Garcia-Pichel, the answer to the mystery of what is "at the heart...

New research highlighting coastal locations where coral can better withstand rising sea temperatures, a leading cause of stress to coral reefs, may guide efforts to conserve the largest living structures on Earth. The findings hold promise for an estimated 100 million people living along the coasts of tropical developing countries whose livelihoods and welfare depend directly on coral reefs, but are currently under threat from climate change. In a report published in an online edition of...

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...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
