Lessons In Coral Reef Survival From Deep Time
2012-01-23 05:13:49

Lessons from tens of millions of years ago are pointing to new ways to save and protect today´s coral reefs and their myriad of beautiful and many-hued fishes at a time of huge change in the Earth´s systems. The complex relationship we see today  between fishes and corals developed relatively recently in geological terms — and is a major factor in shielding reef species from extinction, says Professor David Bellwood of the ARC Centre of Excellence for Coral Reef...

Recent experiments conducted at the Australian Institute of Marine Science (AIMS) produced striking results, showing for the first time that corals hosting a single type of “zooxanthellae” can have different levels of thermal tolerance — a feature that was only known previously for corals with a mix of zooxanthellae. Zooxanthellae are algal cells that live within the tissue of living coral and provide the coral host with energy; the relationship is crucial for the...

Another Outbreak Of Coral Disease Hits The Reefs Of Kāneʿohe Bay, Oʿahu
2012-01-08 05:25:27

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 discovered an outbreak of coral disease called Montipora White Syndrome (MWS) in KāneÊ¿ohe Bay, OÊ¿ahu. (MWS) was discovered affecting coral reefs in KāneÊ¿ohe Bay, OÊ¿ahu.  Follow-up surveys found that...

Image 1 - Trouble In Paradise: Ocean Acidification This Way Comes
2012-01-06 05:09:08

Sustainability of tropical corals in question, but some species developing survival mechanisms Double, double toil and trouble; Fire burn, and caldron bubble. ---Shakespeare, Macbeth Mo'orea, it's called--this island in French Polynesia that's been dubbed the most beautiful island in the world. Here Tahitian breezes dance across crystal blue waters and beneath the tropical seas lies a necklace of coral reefs that encircles Mo'orea like a string of brightly colored jewels....

Two eminent tropical marine scientists today urged Australians to get behind a plan by the Federal Government to transform nearly a million square kilometers of the Coral Sea into the world´s largest marine park. “The Coral Sea is one of a handful of places in the world where a very large oceanic no-take park can be created and monitored in a single national jurisdiction,” say Professors Terry Hughes and Bob Pressey of the ARC Centre of Excellence for Coral Reef Studies...

Some organisms already experiencing ocean acidification levels not predicted to be reached until 2100 A group of 19 scientists from five research organizations have conducted the broadest field study of ocean acidification to date using sensors developed at Scripps Institution of Oceanography, UC San Diego. The study, "High-Frequency Dynamics of Ocean pH: A Multi-Ecosystem Comparison," is reported in today's issue of the journal PLoS One. It is an important step toward understanding how...

Belize Protected Area Boosting Predatory Fish Populations
2011-12-23 05:27:43

Herbivorous fish needed for reef recovery still lagging A 14-year study by the Wildlife Conservation Society in an atoll reef lagoon in Glover's Reef, Belize has found that fishing closures there produce encouraging increases in populations of predatory fish species. However, such closures have resulted in only minimal increases in herbivorous fish, which feed on the algae that smother corals and inhibit reef recovery. The findings will help WCS researchers in their search for new...

Parrot Fish Are The Constant Gardeners Of The World's Reefs
2011-12-09 03:38:26

Australian scientists have urged greater consideration for the brilliantly-hued parrot fishes that tend and renew the world´s imperiled coral reefs. “Parrotfishes are the constant gardeners of the reef. They play a crucial role in keeping it healthy, suppressing weed, removing sediment and helping the corals to regrow after a setback,” explains Professor David Bellwood of the ARC Centre of Excellence for Coral Reef Studies and James Cook University. In a major new study...

Australian scientists have discovered that some tropical fish have a greater capacity to cope with rising sea temperatures than previously thought — by adjusting over several generations. The discovery, by researchers at the ARC Centre of Excellence for Coral Reef Studies, James Cook University and CSIRO sheds a ray of hope amid the rising concern over the future of coral reefs and their fish under the levels of global warming expected to occur by the end of the 21st century....

LANDOVER, MD, Dec. 2, 2011 /PRNewswire/ - Twenty five years ago, on December 4, 1986, Walter Wyatt's plane crashed in the waters of Cay Sal Bank, a remote area between Cuba and The Bahamas. It sank almost immediately. Walter, who now lives in Enterprise, Alabama, spent a night in the ocean fending off sharks, plugging holes in his leaking life vest, and hoping for a merciful end. The Coast Guard located and saved him the next morning and his harrowing experience made many headlines....

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...

Foxface Rabbitfish, Siganus vulpinus

Image Credit: Dr. Wayne Meadows (NOAA)/Wikipedia The foxface rabbitfish is found in coral rich lagoons, and reefs in the coastal water of the Western Pacific. Around the western Philippines, Indonesia, New Guinea, the Great Barrier Reef, New Caledonia, Caroline Islands, and the Marshall Islands. It has also been sighted around Vanuatu, Nauru, Kiribati, and recently Tonga. Adults usually swim in pairs, but the juveniles have been known to form schools. The adult foxface rabbitfish is...

Barrier Reef Anemonefish, Amphiprion akindynos
2012-05-11 12:04:43

The Barrier Reef Anemonefish (Amphiprion akindynos) is native to the marine lagoons and reefs in the Western Pacific Ocean.  It lives at a depth of around eighty-two feet in temperatures fluctuating between fifty degrees Fahrenheit to 89.6 degrees Fahrenheit. Its range includes northern New South Wales, the Loyalty Islands, Tonga, New Caledonia, Coral Sea, and the Great Barrier Reef. They are typically seen near or within the tentacles of their host anemones. They will inhabit anemones like...

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...
