Coral reefs in the Indo-Pacific region, including the Great Barrier Reef, recover faster from major stresses than their Caribbean counterparts, leading marine scientists said today. Dr George Roff and Professor Peter Mumby from the ARC Centre of Excellence for Coral Reef Studies and The University of Queensland told the 12th International Coral Reef Symposium in Cairns that coral reefs in the Indo-Pacific Ocean are naturally tougher than the Caribbean reefs. "The main reason that...

Scientists have discovered two viruses that appear to infect the single-celled microalgae that reside in corals and are important for coral growth and health, and they say the viruses could play a role in the serious decline of coral ecosystems around the world. These viruses, including an RNA virus never before isolated from a coral, have been shown for the first time to clearly be associated with these microalgae called Symbiodinium. If it's proven that they are infecting those algae and...

redOrbit Staff & Wire Reports - Your Universe Online The acid levels of the world's oceans are increasing far faster than scientists had expected, making it one of the biggest threats to coral reefs and threatening both food supplies and the tourism industry, the head of the U.S. National Oceanic and Atmospheric Administration (NOAA) told reporters Monday. Speaking with Kristen Gelineau of the Associated Press (AP), Jane Lubchenco, head of the American scientific organization, said...

Color Changes In Coral Reefs Due To Increased Growth
2012-07-10 21:21:09

New research has provided insight into the basic immune response and repair mechanisms of corals to disease and changing environmental conditions. The study, published in the latest issue of the journal Coral Reefs, found that increased growth is the underlying physiological process associated with disease, wounding and stress-related color changes in reef-building corals. The study investigated distinct green fluorescent protein (GFP)-like pigments responsible for the green, red and...

Like their warrior ancestors, leaders of many Pacific Island nations have been making efforts to safeguard their countries, this time by sounding an alarm as the impact of climate change becomes more apparent.  Today their efforts received a big boost with the release of a Scientific Consensus Statement on Climate Change and Coral Reefs that is supported by over 2,600 scientists, showing the threats that reef corals are under across the globe and calling for governments worldwide to take...

Marine scientists at the University of North Carolina at Chapel Hill have linked the decline in growth of Caribbean forereef corals – due to recent warming – to long-term trends in seawater temperature experienced by these corals located on the ocean-side of the reef. The research was conducted on the Mesoamerican Barrier Reef System in southern Belize. The results were revealed online in the July 8 issue of Nature Climate Change, a journal that publishes research on the...

Climate Change Affected Coral Reefs In Ancient Times
2012-07-06 12:20:36

Brett Smith for redOrbit.com - Your Universe Online Climate change has historically affected the growth of coral reefs, with some reefs experiencing a long-term growth stoppage around 4,000 years ago, according to newly published research in the journal Science. An international team of scientists, who used radiocarbon dating and other research techniques, said that the growth stoppage they identified in eastern Pacific reefs took 2,500 years to recover from. "We were shocked to find...

Some coral reef fish may be better prepared to cope with rising CO2 in the world´s oceans — thanks to their parents. Researchers at the ARC Centre of Excellence for Coral Reef Studies (CoECRS) today reported in the journal Nature Climate Change, encouraging new findings that some fish may be less vulnerable to high CO2 and an acidifying ocean than previously feared. “There has been a lot of concern around the world about recent findings that baby fish are highly...

Crown Of Thorns Starfish, Acanthaster planci
2013-11-11 10:54:41

The crown-of-thorns starfish (Acanthaster planci) is a species of starfish that is classified within the Acanthasteridae family. This species has a large range that extends from the Red Sea to the African coasts in the east and from the Indian Ocean to the western coasts of Central America. It prefers a habitat in coral reefs, which can be harmed if population numbers are too high. Damage occurs when filamentous algae covers bare skeletons of coral and the starfish move in to feed, stripping...

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...

Knotted Fan Coral, (Melithaea ochracea), is a species of colonial soft coral that is found in tree-like fans on shallow reefs in the South China Sea between Taiwan and Indonesia, including Singapore and Malaysia. In Taiwan, it is the most widespread coral in its family Gorgonacea. It is found on the higher parts of reef fronts where its numerous small polyps can feed at water flow rates varying from 1.6 to 16 inches per second. This species usually grow to about 8 inches in length, with...

Leaf Plate Montipora, (Montipora capricornis), also known as Vase Coral, Cap Coral, or simply Montipora, is a species of stony coral found in the Indian and Pacific oceans. It is also found in reefs in the Red Sea. It usually inhabits the top half of the reef where photosynthesis can occur. It branches out from the foundation into an area with adequate sunlight. This species forms flat, plating colonies. The colonies expand by adding to their foundations and further spreading out....

Nephtheidae is a family of soft corals known as carnation corals, tree corals or colt soft corals. These corals are very striking and show a wide range of rich colors including red, pink, yellow and purple. These corals are mainly tree-like in that they branch out and have little knobs on the end of their rubbery branches. Another name given these animals are broccoli corals, due to the fact that their polyps retract in the daytime, giving them the resemblance of the vegetable. The polyps...
