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....

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...

New research has found that hurricane activity is 'clustered' rather than random, which has important long-term implications for coastal ecosystems and human population. The research was carried out by Professor Peter Mumby from The University of Queensland Global Change Institute and School of Biological Sciences, Professor David Stephenson and Dr Renato Vitolo (Willis Research Fellow) at the University of Exeter's Exeter Climate Systems research centre. Tropical cyclones and hurricanes...

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...

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...

Historical reconstruction reveals humans contributed to both degradation and recovery of coral reefs 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 reefs and island societies as a model social-ecological system, a team of...

Australia should show a strong international lead in protecting the oceans and sea-life against overexploitation and other human impacts, a leading marine scientist says. In the lead up to the ℠Coral Reefs: Coast to Coast Symposium´ to be held in Fremantle, WA, on October 20-21, convener Professor Terry Hughes, the director of the ARC Centre of Excellence for Coral Reef Studies at James Cook University, is urging governments State and Federal to up Australia´s commitment to...

New Study Uncovers Predictable Sequence Toward Coral Reef Collapse
2011-09-29 04:06:48

Research identifies 8 factors that can alert managers to the threat of overfishing in otherwise healthy-looking reefs Coral reefs that have lots of corals and appear healthy may, in fact, be heading toward collapse, according to a study published by the Wildlife Conservation Society and other groups. Using data from coral reef systems across the western Indian Ocean, an international team of researchers identified how overfishing creates a series of at least eight big changes on reefs...

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...
