A Changing Climate May Not Spell Doom For Coral Reefs After All
2013-10-30 09:18:53

April Flowers for redOrbit.com - Your Universe Online A new study from the National Oceanic and Atmospheric Administration (NOAA) and its academic partners reveals that coral reefs may be able to adapt to moderate climate warming, improving their chance of surviving through the end of this century, if there are large reductions in carbon dioxide emissions. The findings, published online in the journal Global Change Biology, also suggest corals have already adapted to part of the warming...

Coral Chemical Affects Climate
2013-10-24 15:24:33

Brett Smith for redOrbit.com - Your Universe Online Anyone who has ever been to the ocean knows that signature smell of sea water. One of the molecules responsible for that smell is actually derived from a chemical made by tiny coral animals called dimethylsulphoniopropionate (DMSP). According to a new study in the journal Nature, Australian marine scientists have discovered the first evidence that DMSP plays a major role in local climate. The molecule offers the coral animals cellular...

Drone Creates Detailed Coral Reef Maps

[ Watch the Video: Coral Reef Mapping With The Help Of Drones ] Brett Smith for redOrbit.com - Your Universe Online The War on Terror may have given unmanned drones a bad name, but a research team from Stanford University just might be able to rehabilitate that image. Ved Chirayath, an aeronautics researcher, and Steven Palumbi, a marine biologist, have started using an unmanned drone and cutting-edge computer software to map and measure centuries-old corals. Equipped with several...

Eilat's Corals Have Better Chance Of Survival Than Other Sites
2013-09-30 10:40:55

The Hebrew University of Jerusalem Israel's southern Red Sea resort of Eilat, one of whose prime attractions is its colorful and multi-shaped underwater coral reefs, may have a clear advantage in the future over rival coral-viewing sites around the world, scientists at the Hebrew University of Jerusalem and Bar-Ilan University have found. Coral reefs, earth's richest and most diverse ecosystem, are deteriorating rapidly. One of the most devastating causes for that deterioration is coral...

U.S. National Oceanic and Atmospheric Administration (NOAA) has awarded a Phase II - Small Business Innovative Research (SBIR) grant to Polestar Technologies to develop methods of monitoring ocean acidification and coral reef decimation. Needham Heights, MA (PRWEB) September 28, 2013 The rapid decline of living coral reefs has been a major concern of oceanographers and aqua-agriculturists worldwide. The well-being of our planet is directly related to the health of our oceans. The White...

Coral Decline Affects Crustacean Biodiversity
2013-09-23 15:48:53

Brett Smith for redOrbit.com - Your Universe Online With many scientists expecting climate change to have a devastating effect on the world’s coral reefs over the coming century, new research from the University of Florida indicates that crustacean populations living near rapidly declining reef habitats could be at risk. Appearing in the November issue of the journal Geology, the new study is based on an analysis of the fossil record surrounding decapod crustaceans, a group that...

Sharks Linked To Coral Health
2013-09-19 09:53:11

Brett Smith for redOrbit.com - Your Universe Online Sharks play an important role in the food web of a marine ecosystem and a study recently published in the journal PLOS ONE has found that overfishing of these predators can have a disruptive effect on coral reefs. "Where shark numbers are reduced due to commercial fishing, there is also a decrease in the herbivorous fishes which play a key role in promoting reef health," said study author Jonathan Ruppert, a marine ecologist with the...

Coral White Plague Is Viral Not Bacterial
2013-09-13 09:53:53

Brett Smith for redOrbit.com - Your Universe Online Just as the black plague laid waste to communities across Medieval Europe, a 'white plague' has been decimating marine corals in the Caribbean. Once thought to be caused mainly by bacteria, researchers at Oregon State University have found that a group of small, circular, single-strand DNA (SCSD) viruses are connected to the dramatic rise of white plague that has occurred in recent decades. The Oregon researchers said they are...

The worst impacts of climate change on the world's poorest fishing communities can likely be avoided by careful management of the local environment and investing in the diversification of options for local people, according to the Wildlife Conservation Society and James Cook University. Climate change is already putting pressure on fishers who depend on nature for their livelihoods. In a new study, scientists found large differences in the potential to adapt based on the local mixture of...

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...
