Image 1 - Coral Reefs May Support More Biodiversity Than Thought
2011-11-03 04:00:52

Smithsonian scientists and colleagues conducted the first DNA barcoding survey of crustaceans living on samples of dead coral taken from the Indian, Pacific and Caribbean oceans. The results suggest that the diversity of organisms living on the world's coral reefs is seriously underestimated. The team's research "The Diversity of Coral Reefs: What Are We Missing?" was published in October in the journal PLoS ONE. At depths of 26 to 39 feet, the scientists collected dead coral from five...

A team of researchers from the Hawai'i Institute of Marine Biology (HIMB) have developed an interactive global map of corals and zooxanthellae as part of a hybrid web application titled GeoSymbio. This application provides global-scale biological and ecosystem information on symbiotic zooxanthellae called Symbiodinium which are uni-cellular, photosynthetic dinoflagellates that live inside the cells of other marine organisms like anemones, jellyfish, and corals. Symbiodinium are responsible...

Hawaiian Coral Reefs Valued At $33.5 Billion
2011-10-22 04:55:23

A National Oceanic and Atmospheric Administration (NOAA) survey of U.S. residents has discovered that Americans estimate the value of Hawaii's coral reefs at $33.57 billion per year, the scientific agency reported on Friday. According to an NOAA press release, the organization conducted a "scientifically developed national Internet survey of more than 3,100 households" from throughout the entire country, not just the state of Hawaii or the coastal area, from June through October 2009....

2011-10-18 08:46:40

Scientists studying coral reefs in and around the South Pacific have found that some seaweed can cause coral bleaching and suppress photosynthesis by emitting anti-coral chemicals. As part of their study, researchers have identified and mapped the chemical structure of molecules used by certain types of marine seaweed that kill or inhibit growth of reef-building coral. Chemicals found on the surfaces of several species of seaweed have been shown to harm coral, suggesting that competition...

Coral reefs are among the most diverse ecosystems on the planet, second only to tropical rain forests. Bird's nest coral (Seriatopora hystrix) is common throughout the Indo-Pacific and is able to live across a range of depths. However, there is little gene flow between the coral populations at each depth and even the algal endosymbionts (Symbiodinium), which provide energy for the corals to survive, are genetically different across habitats. New research published in BioMed Central's open...

Historical reconstruction reveals humans contributed to both degradation and recovery of coral reefs STONY BROOK, N.Y. and STANFORD, Calif., Oct. 7, 2011 /PRNewswire-USNewswire/ -- Changing human activities coupled with a dynamic environment over the past few centuries have caused fluctuating periods of decline and recovery of corals reefs in the Hawaiian Islands, according to a study sponsored in part by the Institute for Ocean Conservation Science at Stony Brook University. Using the...

New Study Challenges Whether Corals Will Benefit From Marine Reserves' Protection
2011-10-04 10:58:18

The ability of marine reserves to replenish fish stocks has been studied extensively, but evidence of their ability to benefit shallow-water communities to thrive remains a mystery. A team of scientists from the University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science recently tested whether 10 years of reserve designation has translated into positive impacts on coral communities in Glover's Reef Marine Reserve, Belize. Results from their surveys of 87 patch reefs both...

Honduran Earthquake Destroyed Belizean Barrier Reef Coral

  Earthquake underscores need for conservation planning to take into account infrequent natural disasters Earth's coral reefs have not been faring well in recent decades, facing multiple threats from pollution, disease, elevated water temperatures, and overfishing. Often referred to as the "rainforests of the Sea," coral reefs support a wide variety of marine life, help protect shorelines, and contribute significantly to tourism and the fishing industry. A new study looks at a rare...

Image 1 - Seeking Keys To Coral Reef Renewal
2011-09-06 06:14:32

  Vital clues to coral reef recovery have been identified in a remarkable research project in which three scientists labored to hand-build 30 coral reefs from hundreds of tons of rock and gravel. Working in a shallow, sandy area of Kimbe Bay, Papua New Guinea, the team constructed their artificial reefs over several weeks, with just a boat and their bare hands, to find out whether it is possible to rescue a damaged coral reef from obliteration and restore its richness....

A New Hypothesis On Ocean Acidification
2011-08-31 06:17:11

  Since the beginning of the Industrial Revolution, the concentration of carbon dioxide in the atmosphere has been rising due to the burning of fossil fuels. Increased absorption of this carbon by the oceans is lowering the seawater pH (the scale which measures how acidic or basic a substance is) and aragonite saturation state in a process known as ocean acidification. Aragonite is the mineral form of calcium carbonate that is laid down by corals to build their hard skeleton....

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...

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....
