Study Shows Adaptive Capacity Of Reef Corals To Climate Change May Be Widespread
2012-04-12 07:42:53

Global survey of corals using high sensitivity genetic analysis shows many species can host multiple symbionts. A new study by scientists at the University of Miami's Rosenstiel School of Marine & Atmospheric Science suggests that many species of reef-building corals may be able to adapt to warming waters by relying on their closest aquatic partners - algae. The corals' ability to host a variety of algal types, each with different sensitivities to environmental stress, could offer a...

Corals may be better placed to cope with the gradual acidification of the world´s oceans than previously thought — giving rise to hopes that coral reefs might escape climatic devastation. In new research published in the journal Nature Climate Change, an international scientific team has identified a powerful internal mechanism that could enable some corals and their symbiotic algae to counter the adverse impact of a more acidic ocean. As humans release ever-larger amounts of...

A team of international scientists working in the central Pacific have discovered that coral which has survived heat stress in the past is more likely to survive it in the future. The study, published today in the journal PLoS ONE, paves the way towards an important road map on the impacts of ocean warming, and will help scientists identify the habitats and locations where coral reefs are more likely to adapt to climate change. "We're starting to identify the types of reef environments...

Novel excavation technique attributes prior damage to land clearing and overfishing The decline of Caribbean coral reefs has been linked to the recent effects of human-induced climate change. However, new research led by scientists at Scripps Institution of Oceanography at UC San Diego suggests an even earlier cause. The bad news — humans are still to blame. The good news — relatively simple policy changes can hinder further coral reef decline. Employing a novel excavation...

As corals continue to decline in abundance around the world, researchers are turning their attention to a possible cause that´s almost totally unexplored — viral disease. It appears the corals that form such important parts of marine ecosystems harbor many different viruses — particularly herpes. And although they don´t get runny noses or stomach upset, corals also are home to the adenoviruses and other viral families that can cause human colds and gastrointestinal...

Gulf Oil Spill Seriously Impacted Deep-sea Corals: Study
2012-03-27 07:34:00

Scientists reported on Monday that they have found “compelling evidence” that the Deepwater Horizon oil spill in the Gulf of Mexico has seriously impacted deep-sea corals. "These biological communities in the deep Gulf of Mexico are separated from human activity at the surface by 4,000 feet of water,” she said,” said Helen White, Assistant Professor of Chemistry at Haverford College and lead author of the study. “We would not expect deep-water corals to be...

Special conservation zones known as marine protected areas provide many direct benefits to fisheries and coral reefs. However, such zones appear to offer limited help to corals in their battle against global warming, according to a new study. To protect coral reefs from climate change, marine protected areas need to be complemented with policies that can meaningfully reduce greenhouse gas emissions, researchers said. The new study was conducted by scientists from Conservation...

As global warming heats up the Earth´s oceans, one ecosystem stands to be severely threatened: Coral reefs. However, new research has given scientists to be hopeful about the fate of these coral reefs. An international team of researchers has studied a coral population in South-East Asian waters that had survived a bleaching event. What was significant about this reef was that it had also survived another bleaching event 12 years earlier in 1998. The researchers published their...

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...
