Corals Shrinking Around Equator Thanks To Global Warming
2012-12-11 14:34:21

Brett Smith for redOrbit.com - Your Universe Online As the clamoring for a more comprehensive strategy to battle climate change continues, scientists are producing more and more research that suggests incremental changes in global temperature can have a massive effect on ecosystems. A new study from a team of Australian and German researchers showed that when sea surface temperatures increased by about 0.7 degrees Celsius during the last interglacial warm period, the Earth´s...

Government Agency Proposes Dozens Of Coral Species For Endangered Species Act
2012-12-03 16:06:58

Lee Rannals for redOrbit.com — Your Universe Online A new Endangered Species Act listings proposed by the National Oceanic and Atmospheric Association (NOAA) would cover 66 coral species found in the Pacific and the Caribbean. NOAA said that in 2009, it received a petition to list 83 species of reef-building corals under the ESA from the Center for Biological Diversity. The organization found that the Center presented substantial information indicating a listing under the ESA...

Two New Encrusting Anemones Found In Unexpected Locations
2012-11-29 16:44:09

Pensoft Publishers As a result of field work by associate professor James Davis Reimer and two graduate students from the University of the Ryukyus in Okinawa, Japan has found two new species of encrusting anemones, or colonial zoanthids, in unexpected locations. The species belong to the genus Neozoanthus, which was previously known only from a single species in the Indian Ocean. Surprisingly, the new species were found in the Pacific Ocean, in southern Japan and on the Great Barrier...

Seaweed Attacks, Corals Calls For Help
2012-11-09 20:46:42

April Flowers for redOrbit.com — Your Universe Online When toxic seaweed threatens the health of coral, what does the coral do? It calls for help, of course. A new study, published in Science, reveals that corals under attack send signals to fish "bodyguards." The fish respond quickly, moving in to trim back the toxic alga that can kill the coral if not removed in a timely manner. A team from the Georgia Institute of Technology has found evidence that these mutualistic fish...

European Settlement Caused Collapse Of Great Barrier Reef Coral
2012-11-07 10:07:33

Lawrence LeBlond for redOrbit.com - Your Universe Online Australia´s Great Barrier Reef, the largest coral system in the world, so big that it can be seen from space, is one of the planet´s most remarkable natural wonders. But researchers from University of Queensland have now revealed this precious ecosystem is not faring so well. The problem: European settlement and extensive degradation on mainland Australia. The expansion of European settlement in Australia has been...

Sweden’s Säcken Reef Facing Death
2012-10-23 21:13:37

Alan McStravick for redOrbit.com — Your Universe Online The Säcken reef in the Koster Fjord in Sweden is that country´s last remaining cold-water coral reef and it is under a distinct threat of extinction. Like the more common warm-water reefs, cold-water reefs are known for their rich biological diversity. With the Säcken reef in distress, researchers from the University of Gothenburg have started a restoration project extracting healthy corals...

Insights Into Evolution Of Marine Life Provided By Genetic Patterns Of Deep-Sea Coral
2012-10-23 20:52:27

Patterns Also Shed Light on How Environmental Disturbances Affect Aquatic Organisms The ability of deep-sea corals to harbor a broad array of marine life, including commercially important fish species, make these habitat-forming organisms of immediate interest to conservationists, managers, and scientists. Understanding and protecting corals requires knowledge of the historical processes that have shaped their biodiversity and biogeography. While little is known about these processes,...

Coral Reefs Decline And Food Security At Risk
2012-10-18 09:56:07

A new study co-authored by the Wildlife Conservation Society identifies countries most vulnerable to declining coral reef fisheries from a food-security perspective while providing a framework to plan for alternative protein sources needed to replace declining fisheries. The study looked at 27 countries around the world and found two common characteristics: nations with low incomes that lack the ability to adapt to alternative protein sources; and middle-income nations with higher adaptive...

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...
