New research in the FASEB Journal shows how coral reefs cope with environmental stress such as 'extractive activity': Innate immunity defends the colony Much attention has been paid to the fate of wildlife living on and above the Gulf of Mexico's surface. Now, a new research study published in the June 2010 print issue of the FASEB Journal looks toward the seafloor to explain coral susceptibility to disease outbreaks when they encounter environmental stress and to set the stage for...

Damselfish are killing head corals and adding stress to Caribbean coral reefs, which are already in desperately poor condition from global climate change, coral diseases, hurricanes, pollution, and overfishing. Restoring threatened staghorn coral, the damsels' favorite homestead, will take the pressure off the other corals, according to a new study published in the online journal PLoS ONE. The small, belligerently territorial, threespot damselfish kill portions of coral colonies to grow...

The polyps of the new gorgonia discovered, Tauroprimnoa austasensis and Digitogorgia kuekenthali, in the region of Austasen, in the Eastern Weddell Sea, and to the south-east of the Falklands and Isla Nueve (in Chilean Patagonia) respectively, are small and elongated. Both species stand out for the number, shape and layout of the scales of calcium carbonate that cover the polyps, and for the type of ramification of the colonies. "The Tauroprimnoa are characterized by being colonies in the...

A team of Spanish and French researchers has undertaken a pioneer analysis of red coral populations in the oldest Marine Protected Areas (MPA) in the Mediterranean and the impact that fishing activity has had. Results show that MPAs are a guarantee for conserving this species. Mediterranean red coral (Corallium rubrum) has been highly valued for jewelry since ancient times. But intensive fishing, particularly in shallow waters, has transformed populations and hindered the recovery of this...

Field studies have shown for the first time that several common species of seaweeds in both the Pacific and Caribbean Oceans can kill corals upon contact using chemical means. While competition between seaweed and coral is just one of many factors affecting the decline of coral reefs worldwide, this chemical threat may provide a serious setback to efforts aimed at repopulating damaged reefs. Seaweeds are normally kept in check by herbivorous fish, but in many areas overfishing has reduced the...

An international team of marine biologists has found that existing diversity in some coral populations may significantly influence their response to extreme temperature disturbances "” such as those predicted from climate warming. The team demonstrated that natural selection acting on the species of algae living within corals may determine which partnerships will survive when confronted with extreme temperatures changes. The results will be published online in the May 5 issue of the...

An outbreak of a disease called Montipora White Syndrome (MWS) was found in Kaneohe Bay, OÊ»ahu within the last month prompting an interagency response team composed of scientists and students to document the extent, spread and potential causes of the disease. Members of the investigative team included scientists from the University of Hawaii at Mānoa's Hawaii Institute of Marine Biology (HIMB), USGS National Wildlife Health Center and Bishop...

Cornell University researchers have found a new tool to help marine biologists better grasp the processes under the sea: They have created mathematical models to unveil the bacterial community dynamics behind afflictions that bleach and kill coral. (Public Library of Science "“ Biology, March 30, 2010.) Warming waters are triggering coral bleaching and disease in the Caribbean, Indian Ocean and Great Barrier Reef off the Australian coast. Now new mathematical models explain for the...

Coral reefs are slowly becoming extinct and could disappear entirely within the next century -- which could have disastrous results all over the world, experts claim. According to National Oceanic and Atmospheric Administration (NOAA) statistics published in a March 25 Associated Press (AP) article, roughly 19-percent of the Earth's coral reefs have already disappeared, and an additional 15-percent could be gone within the next two decades. Furthermore, Dr. Kent Carpenter, a professor at Old...

DOHA, QATAR, March 21 /PRNewswire-USNewswire/ -- International governments today failed to grant trade protection to the unique and valuable red and pick corals (Coralliidae) used in jewelry and home decor, despite sound science showing that regulation is needed for their continued survival. SeaWeb, an ocean conservation organization whose campaign Too Precious to Wear had called for governments to protect Coralliidae under Appendix II of the Convention on International Trade in Endangered...

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...

Octopus Coral, (Galaxea fascicularis), also known as Fluorescence Grass Coral, Galaxy Coral. Star Coral, Crystal Coral, Brittle Coral and Starburst Coral, is a species of colonial stony coral commonly found on reef slopes in the Indian and Pacific ocean regions, as well as the Red Sea and the Gulf of Aden. It is most commonly found where wave action is weak, usually at a depth of 79 inches to 49 feet below sea level. It is a common coral species among reef aquarium enthusiasts. This coral...

Chalice Corals, are a family of stony corals in the Pectiniidae family. Members of this family are mostly colonial but at least one species, Echinomorpha nishihirai, is solitary. These corals are endemic to the Indian and Pacific oceans. Pectiniids have a number of different forms but are basically streamlined and smooth. Polyps are large and brightly colored and resemble those of members of the Mussidae family of corals. The polyps are only extended at night. Tentacles are translucent,...

Siderastreidae is a family of colonial, reef building stony corals. Members of this family include symbiotic algae in their tissues which help provide their energy requirements. The World Register of Marine Species lists 7 genera within this family: Anomastraea, Coscinaraea, Craterastrea, Horastrea, Psammocora, Pseudosiderastrea, and Siderastrea. Corals in this family vary in form and include massive, thickly encrusting, columnar, and irregular forms. Corallites are linked by flowing...

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....
