Fishing Has Reduced Vital Seaweed Eaters By More Than Fifty Percent
2013-12-04 19:27:07

Scripps Institution of Oceanography, UC San Diego In the first global assessment of its kind, a science team led by researchers at Scripps Institution of Oceanography at UC San Diego has produced a landmark report on the impact of fishing on a group of fish known to protect the health of coral reefs. The report, published in the journal Proceedings of the Royal Society B (Biological Sciences), offers key data for setting management and conservation targets to protect and preserve fragile...

Marine Pollution Impact On Corals Is Harsh, But They Can Recover
2013-11-26 14:24:00

[ Watch the Video: Protection From Marine Pollution Would Help Coral Reefs Recover ] Brett Smith for redOrbit.com - Your Universe Online A new study on coral reefs from a team of Florida and Oregon researchers has found common marine pollution doubled the rate of disease among corals and more than tripled the amount of coral bleaching, an early sign of reef stress. According to the team’s report in Global Change Biology, a three-year, controlled exposure of corals to high levels of...

Abundant, Dominant Corals Still Face Threat Of Extinction
2013-11-16 06:48:46

April Flowers for redOrbit.com - Your Universe Online Scientists generally assume that corals do not face a risk of extinction unless they become very rare, or their range is restricted. A new study, published in the journal Bioscience, reveals that global changes in climate and ocean chemistry affect corals whether scarce or abundant, and often it is the dominant, abundant corals with wide distributions that are affected the most. A research team, led by Charles Birkeland from the...

Scientists Describe Two New Gorgonian Soft Coral Species
2013-11-15 12:50:00

Pensoft Publishers Gorgonians are a type of soft corals easily distinguishable by the complex branching shape, which has also probably inspired their name, coming from the Gorgon Medusa- a creature from the Greek mythology that had hair made of venomous snakes. The existence of Medusa outside myth might be debatable, but gorgonian corals do exist and decorate our ocean with complex patterns and vibrant colors. A recent study in the open access journal Zookeys reveals two new species of...

Substantial costs expected from coral reef loss and declines in shellfisheries; Cold water corals also at risk In a major new international report, experts conclude that the acidity of the world's ocean may increase by around 170% by the end of the century bringing significant economic losses. People who rely on the ocean's ecosystem services – often in developing countries - are especially vulnerable. A group of experts have agreed on 'levels of confidence' in relation to ocean...

An international team of scientists, led by physicists from the University of York, has shed important new light on coral skeleton formation. Their investigations, carried out at the nanoscale, provide valuable new information for scientists and environmentalists working to protect and conserve coral from the threats of acidification and rising water temperatures. As corals grow, they produce limestone – calcium carbonate - skeletons which build up over time into vast reefs. The...

A Changing Climate May Not Spell Doom For Coral Reefs After All
2013-10-30 09:18:53

April Flowers for redOrbit.com - Your Universe Online A new study from the National Oceanic and Atmospheric Administration (NOAA) and its academic partners reveals that coral reefs may be able to adapt to moderate climate warming, improving their chance of surviving through the end of this century, if there are large reductions in carbon dioxide emissions. The findings, published online in the journal Global Change Biology, also suggest corals have already adapted to part of the warming...

Coral Chemical Affects Climate
2013-10-24 15:24:33

Brett Smith for redOrbit.com - Your Universe Online Anyone who has ever been to the ocean knows that signature smell of sea water. One of the molecules responsible for that smell is actually derived from a chemical made by tiny coral animals called dimethylsulphoniopropionate (DMSP). According to a new study in the journal Nature, Australian marine scientists have discovered the first evidence that DMSP plays a major role in local climate. The molecule offers the coral animals cellular...

Drone Creates Detailed Coral Reef Maps

[ Watch the Video: Coral Reef Mapping With The Help Of Drones ] Brett Smith for redOrbit.com - Your Universe Online The War on Terror may have given unmanned drones a bad name, but a research team from Stanford University just might be able to rehabilitate that image. Ved Chirayath, an aeronautics researcher, and Steven Palumbi, a marine biologist, have started using an unmanned drone and cutting-edge computer software to map and measure centuries-old corals. Equipped with several...

Eilat's Corals Have Better Chance Of Survival Than Other Sites
2013-09-30 10:40:55

The Hebrew University of Jerusalem Israel's southern Red Sea resort of Eilat, one of whose prime attractions is its colorful and multi-shaped underwater coral reefs, may have a clear advantage in the future over rival coral-viewing sites around the world, scientists at the Hebrew University of Jerusalem and Bar-Ilan University have found. Coral reefs, earth's richest and most diverse ecosystem, are deteriorating rapidly. One of the most devastating causes for that deterioration is coral...

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
2013-04-20 15:49:21

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...
