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...

Shocking Reefs Back To Life
2013-09-02 10:56:39

Brett Smith for redOrbit.com - Your Universe Online Major weather events can shock an ecosystem, but they are also part of Earth’s natural cycle, and many species are adept at recovering from an environmental shake up. New research from a joint team of Australian and Swedish researchers has shown that ecosystem shocks caused by changing climate or seasons could play a key role in bringing back some of the world’s badly degraded coral reefs, according to a new report in the journal...

Fish Larvae Use Small Of Corals To Get Home
2013-08-29 11:24:50

[ Watch The Video: o-DISC Deployed Off One Reef Island ] Lee Rannals for redOrbit.com - Your Universe Online Scientists writing in the journal PLOS ONE say that if fish larvae were lost, they could just sniff their way back home. The study establishes that reef fish larvae can smell the presence of coral reefs from as far away as several miles offshore. The larvae are then able to use this scent to help guide themselves back home. The researchers were aiming to study the response of...

Animal Species Ocean Acidification
2013-08-26 09:36:17

Brett Smith for redOrbit.com - Your Universe Online When atmospheric carbon dioxide dissolves into the ocean, it forms carbonic acid, which in turn lowers the water's pH levels and causes oceanic acidification. The phenomenon is expected to occur at increasing rates as carbon dioxide emissions around the world continue to rise. In a report published in Nature Climate Change, two researchers from the Alfred Wegener Institute, Helmholtz-Centre for Polar and Marine Research (AWI) in...

Epic Ocean-spanning Voyages Of Coral Larvae Revealed
2013-08-20 15:44:55

University of Miami Rosenstiel School of Marine & Atmospheric Science Models provide first-ever simulated glimpse into dispersal and potential effects of climate change A new computer simulation conducted at the University of Bristol (UB) and University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science has revealed the epic, ocean-spanning journeys traveled by millimeter-sized coral larvae through the world's seas. The study, published in Global Ecology and...

Coral Reef Biodiversity More Important To Divers Than Fish Abundance

[WATCH VIDEO: Tamar Artificial Reef Now Teeming With Life] Brett Smith for redOrbit.com - Your Universe Online With ecotourism on the rise, determining what elements of a nature-based attraction are most appealing can have significant consequences financially and for raising awareness of conservation issues. In a new study of the Negev from Ben-Gurion University (BGU) in Israel, researchers found that divers were able to differentiate between an artificial reef’s biodiversity and...

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...
