Research can help assess impacts of climate change, other threats to coral reef ecosystems University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science scientist Chris Langdon and colleagues developed a new tool to monitor coral reef vital signs. By accurately measuring their biological pulse, scientists can better assess how climate change and other ecological threats impact coral reef health worldwide. During a March 2009 experiment at Cayo Enrique Reef in Puerto Rico, the...

Preserving an intact population of weed-eating fish may be vital to saving the world's coral reefs from being engulfed by weed as human and climate impacts grow. A new study by researchers at the ARC Centre of Excellence for Coral Reef Studies has found weed-eaters like parrotfish and surgeonfish can only keep coral reefs clear of weed up to a point. After the weeds reach a certain density, they take over entirely and the coral is lost. For some years researchers have pinned their hopes on...

Thriving coral triangle depends on S. China Sea and Solomon Is. for reef diversity University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science faculty were part of an international scientific team to show that strong links between the corals reefs of the South China Sea, West Pacific and Coral Triangle hold the key to preserving fish and marine resources in the Asia-Pacific region. Rosenstiel School researchers Drs. Claire Paris and Robert Cowen and colleagues from the ARC...

Warming seas, rising levels of atmospheric carbon dioxide and other factors such as over-fishing could wipe out the world's coral reefs by 2050 unless urgent action is taken to counteract these threats, environmental advocates warned on Wednesday. More than three quarters of all reefs are currently threatened, said advocates from U.S. government and non-governmental organizations while releasing the report entitled, "Reefs at Risk Revisited." Swift action must be taken to protect these...

An international scientific team has shown that strong links between the corals reefs of the south China sea, West Pacific and Coral Triangle hold the key to preserving fish and marine resources in the Asia-Pacific region. Research by Dr Johnathan Kool of the ARC Centre of Excellence for Coral Reef Studies and James Cook University, and his colleagues, has established that the richest marine region on Earth "“ the Coral Triangle between Indonesia, Malaysia and the Philippines "“...

More than a third of coral reef fish species are in jeopardy of local extinction from the impacts of climate change on coral reefs, a new scientific study has found. (Local extinction refers to the loss of species from individual locations, while they continue to persist elsewhere across their range.) A new predictive method developed by an international team of marine scientists has found that a third of reef fishes studied across the Indian Ocean are potentially vulnerable to increasing...

The more humanity acidifies and warms the world's oceans with carbon emissions, the harder we will have to work to save our coral reefs. That's the blunt message from a major new study by an international scientific team, which finds that ocean acidification and global warming will combine with local impacts like overfishing and nutrient runoff to weaken the world's coral reefs right when they are struggling to survive. Modeling by a team led by Dr Ken Anthony of the ARC Centre of Excellence...

New research reveals that weather-battered northern Australia could be in for more extreme weather events. Researchers studied coral cores that reveal a centuries-old climate record for the region, according to a recent Reuters report Corals can help scientists go back in time by revealing years that were unusually wet or dry.  The annual changes or variations in weather are recorded in growth rings that can be studied by drilling and extracting long cores. "The corals are providing...

Tropical Cyclone Yasi, a severe, top-category storm, ripped through Australia's northeast tourist coast Thursday, leveling houses and decimating crops as it hit land near the city of Cairns, gateway to Australia's Great Barrier Reef. The reef could face a slow recovery after recent flooding spewed toxic waste into its pristine waters. Marine experts say it is too early to assess the extent of the damage but the world's largest living organism, the sprawling coral structure, was very likely...

Things are not always what they seem when it comes to fish"”something scientists at the Smithsonian Institution and the Ocean Science Foundation are finding out. Using modern genetic analysis, combined with traditional examination of morphology, the scientists discovered that what were once thought to be three species of blenny in the genus Starksia are actually 10 distinct species. The team's findings were published in the scientific journal ZooKeys, Feb. 3. Starksia blennies, small...

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...
