Corals Keep Climate Record
2013-12-16 10:19:07

Brett Smith for redOrbit.com - Your Universe Online In addition to providing shelter and being an important part of a marine ecosystem, coral reefs can also serve as a record of long-term changes to the ecosystem. According to a new study published on Sunday in the journal Nature, an analysis of Pacific corals has revealed changes at the bottom of the marine food web observed in recent decades in the North Pacific Subtropical Gyre may have started over 150 years ago. The study team...

Coral Reefs Hold Surprising Species Diversity
2013-12-14 04:35:27

redOrbit Staff & Wire Reports - Your Universe Online It is widely known that coral reefs are being put in jeopardy by rising water temperatures caused by climate change. A team of marine biologists, led by Penn State University, has made a surprising discovery that suggests that very similar looking coral species actually differ in how they survive in harsh environments. "We've found that previously unrecognized species diversity was hiding some corals' ability to respond to climate...

The Virgin Islands are known as a hot spot for tourism – snorkeling, diving, deep sea fishing, sailing and cruise ship visits. Unfortunately, say researchers at the University of the Virgin Islands, the territory is also a hotspot for coral disease. St. Thomas, U.S. Virgin Islands (PRWEB) December 12, 2013 The Virgin Islands are known as a hot spot for tourism – snorkeling, diving, deep sea fishing, sailing and cruise ship visits. Unfortunately, say researchers at the University of...

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...

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

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...
