Image 1 - Coral Reef History Linked To 700 Years Of Human And Environmental Activity
2011-10-04 10:49:00

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...

An international team of scientists has achieved a major breakthrough in fishing sustainability on coral reefs which could play a vital role in preventing their collapse. “Fishermen and scientists have long wondered how many fish can be taken off a reef before it collapses, says Dr Nick Graham of the ARC Centre of Excellence (ARC CoE) for Coral Reef Studies and James Cook University. “The consequences of overfishing can be severe to the ecosystem and may take decades to...

  Captive breeding could transform the saltwater aquarium trade and save coral reefs Marine biologists at The University of Texas at Austin Marine Science Institute are developing means to efficiently breed saltwater aquarium fish, seahorses, plankton and invertebrates in captivity in order to preserve the biologically rich ecosystems of the world's coral reefs. These scientists believe their efforts, and those of colleagues around the world, could help shift much of the $1...

Counting Fish From Space

  A young research scientist who has studied fish from outer space in order to help predict the future of our coral reefs and their fish stocks is this year´s winner of a prestigious science prize. Dr Nick Graham of the ARC Centre of Excellence for Coral Reef Studies and James Cook University is this year´s laureate in the Life Sciences & Biological Sciences category of the Scopus Young Researcher of the Year Awards. The Scopus Awards are presented annually by...

Image 1 - Underwater Laboratory Study May Help Manage Seaweed-eating Fish That Protect Coral
2011-09-18 06:51:09

  A team of researchers from the Georgia Institute of Technology is using the Aquarius underwater laboratory off the coast of Florida to study how the diversity of seaweed-eating fish affects endangered coral reefs. The research mission, which began Sept. 13, may provide new information to help scientists protect and even restore damaged coral reefs in the Caribbean. Led by Mark Hay, a Georgia Tech professor of biology, the 10-day mission includes two Ph.D. students and a...

Honduran Earthquake Destroyed Belizean Barrier Reef Coral
2011-09-12 08:42:15

  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....

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...

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...
