New Study On Coral Reef Formations Lays To Rest Conflicting Theories
2013-05-14 07:53:01

April Flowers for redOrbit.com - Your Universe Online In the South Pacific, three types of coral reef island formations have fascinated geologists for ages. The coral of Tahiti forms a “fringing” reef, with a shelf growing close to the island´s shore. In Bora Bora, the “barrier” reefs are separated from the main island by a calm lagoon. Manuae represents the last type, an “atoll,” which appears as a ring of coral enclosing a lagoon with no island at...

Coral Reefs Still In Danger But Demise Not Inevitable
2013-05-10 10:20:05

April Flowers for redOrbit.com - Your Universe Online Although scientists agree that coral reefs are in decline, a new study demonstrates that the collapse of such reefs can still be avoided with a combination of local and global action. "People benefit by reefs' having a complex structure — a little like a Manhattan skyline, but underwater," said Peter Mumby of The University of Queensland. "Structurally complex reefs provide nooks and crannies for thousands of species and...

Coral reefs support around half a billion people, but are severely threatened; the Coralbots team plan to revolutionize how such threats are tackled, by using teams of autonomous underwater robots. The Coralbots Kickstarter campaign (closing May 26th) is reaching out to individuals and corporations who wish to make a lasting positive impact on the marine environment, and now offering ways for backers to be directly involved in the project. Edinburgh, UK (PRWEB) May 04, 2013 The ocean is...

Coral Bleaching Study Explains Different Responses To Climate Change
2013-04-24 12:24:35

Brett Smith for redOrbit.com - Your Universe Online When corals become stressed, they expel their symbiotic algae companions in a process known as “bleaching.” Corals can survive the bleaching, but it leaves them highly vulnerable and often results in die-off. As a changing climate threatens to bleach the corals of the world´s oceans on a massive scale, a team of researchers from Northwestern University has found that some corals facilitate bleaching through the...

Israeli Scientists Discover Why Soft Corals Pulsate
2013-04-23 14:17:24

The Hebrew University of Jerusalem [ Watch the Video Pulsating Coral In The Gulf Of Eilat ] Scientists from the Hebrew University of Jerusalem and the Technion-Israel Institute of Technology have discovered why Heteroxenia corals pulsate. Their work, which resolves an old scientific mystery, appears in the current issue of PNAS (Proceedings of the National Academy of Sciences in the US). One of the most fascinating and spectacular sights in the coral reef of Eilat is the perpetual...

Coral Reefs Also Under Threat From Air Pollution
2013-04-08 04:30:56

redOrbit Staff & Wire Reports - Your Universe Online Fine particles in the air resulting from burning coal or volcanic eruptions can negatively affect coral growth, a team of climate scientists and coral ecologists from the UK, Australia and Panama has discovered. The study, which appears in this week´s edition of the journal Nature Geoscience, found that coral reefs respond to changes in the concentration of atmospheric pollution. Those particulates can shade the corals from...

Sustainable Fishing Practices Reap Local Rewards
2013-03-28 16:28:27

Cell Press Communities that act locally to limit their fish catches will reap the rewards of their action, as will their neighbors. That's the conclusion of a study reported on March 28 in the Cell Press journal Current Biology of the highly sought-after fish known as squaretail coral grouper living in five community-owned reef systems in Papua New Guinea. "We found that many larvae that were produced by the managed adults return to that same fish population, which means that the same...

Microborers Represent New Threat To Earth’s Coral Reefs
2013-03-18 11:42:49

Brett Smith for redOrbit.com - Your Universe Online Previous studies have shown that warming oceans and ocean acidification threaten to destroy the ocean´s coral reefs. Now, a new study from Australian researchers published in the journal Global Change Biology suggests that yet another threat could decimate these delicate ecosystems. “Our research shows that when seawater is both acidic and warm — which is predicted to happen under future climate scenarios — 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

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...
