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...

LANDOVER, Md., Nov. 17, 2010 /PRNewswire/ -- Having recently observed its 10th anniversary, the Khaled bin Sultan Living Oceans Foundation is preparing for its next scientific research and education project, the Global Reef Expedition, which will launch in 2011 and continue through 2014. The primary scientific goals of the Expedition are to map and characterize coral reef ecosystems, identify their current status and major threats, and examine factors that enhance their capacity to resist,...

Univ. of Miami scientists illustrate threat of increased carbon dioxide to coral reproduction A new study led by scientists at the University of Miami Rosenstiel School of Marine and Atmospheric Science suggests that over the next century recruitment of new corals could drop by 73 percent, as rising CO2 levels turn the oceans more acidic. The research findings reveal a new danger to the already threatened Caribbean and Florida reef Elkhorn corals. "Ocean acidification is widely viewed as an...

Researchers at the Hawai"˜i Institute of Marine Biology (HIMB), an organized research unit in the University of Hawai"˜i at Mānoa's School of Ocean and Earth Science and Technology have made a remarkable new discovery. When most people envision coral, they typically think of shallow-water reef-building corals found along beaches and tropical nearshore habitats. These "typical" corals are dependent upon photosynthetic algae (also known as...

An exhibit at Washington's Natural History Museum is aimed at helping to draw attention to coral reefs, which face stress, degradation and outright extinction due to human activity. About 800 women ranging from ages three to 101 years old volunteered to take on the project by Australian activists Margaret and Christine Wertheim of the Institute for Figuring. The volunteers crocheted multicolored strands of wool to mimic the curls of coral, anemones and starfish. The exhibit is called...

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...

  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
