University of Southampton A new publication from researchers at the University of Southampton and the National Oceanography Centre, Southampton highlights the importance of nutrients for coral reef survival. Despite the comparably small footprint they take on the ocean floor, tropical coral reefs are home to a substantial part of all marine life forms. Coral reefs also provide numerous benefits for human populations, providing food for millions and protecting coastal areas from erosion....

Future Presence Of Fish Near The Equator Threatened Due To Rapid Pace Of Climate Change
2014-02-12 13:59:10

ARC Centre of Excellence for Coral Reef Studies According to an international team of researchers, the rapid pace of climate change is threatening the future presence of fish near the equator. “Our studies found that one species of fish could not even survive in water just three degrees Celsius warmer than what it lives in now,” says the lead author of the study, Dr Jodie Rummer from the ARC Centre of Excellence for Coral Reef Studies (Coral CoE) at James Cook University. Dr...

First Ever Cold Water Coral Reef Found In Greenland
2014-01-28 13:46:36

[ Watch the Video: Cold Water Coral Reef Discovered In Greenland ] Lee Rannals for redOrbit.com - Your Universe Online Researchers have discovered the first ever cold-water coral reef in Greenland at a depth of nearly 3,000 feet below sea-level. Scientists have found several species of coral in Greenland, but this is the first time that an actual reef has been found. The team discovered the Greenlandic reef in southwest Greenland off Cape Desolation south of lvittuut. They found...

Palau Coral Reefs Surprisingly Resistant To Naturally Acidified Waters
2014-01-16 10:54:13

Woods Hole Oceanographic Institution Ocean researchers working on the coral reefs of Palau in 2011 and 2012 made two unexpected discoveries that could provide insight into corals' resistance and resilience to ocean acidification, and aid in the creation of a plan to protect them. The team collected water samples at nine points along a transect that stretched from the open ocean, across the barrier reef, into the lagoon and then into the bays and inlets around the Rock Islands of Palau,...

Competition Between Coral, Seaweed Occurs On A Chemical Scale
2014-01-09 06:32:58

April Flowers for redOrbit.com - Your Universe Online For one particular species of tropical seaweed, competition may have a high cost. Scientists investigating the chemical warfare that takes place on Fijian coral reefs have discovered that one species of seaweed increases its production of noxious anti-coral compounds when placed in contact with reef-building corals. The study, published in Proceedings of the Royal Society B, show that as this seaweed competes chemically with the...

Upstream Forest Conservation Linked To Saving Fiji's Coral Reefs
2013-12-18 13:50:06

Wildlife Conservation Society The health of coral reefs offshore depend on the protection of forests near the sea, according to a new study by the Wildlife Conservation Society that outlines the importance of terrestrial protected areas to coastal biodiversity. In a study conducted by WCS and the University of Queensland evaluating the effects of terrestrial protected area designs on Fiji's coral reefs, it turns out that what's best for land ecosystems is also best for coastal corals....

Corals Keep Climate Record
2013-12-16 10:19:07

Brett Smith for redOrbit.com - Your Universe Online In addition to providing shelter and being an important part of a marine ecosystem, coral reefs can also serve as a record of long-term changes to the ecosystem. According to a new study published on Sunday in the journal Nature, an analysis of Pacific corals has revealed changes at the bottom of the marine food web observed in recent decades in the North Pacific Subtropical Gyre may have started over 150 years ago. The study team...

Fishing Has Reduced Vital Seaweed Eaters By More Than Fifty Percent
2013-12-04 19:27:07

Scripps Institution of Oceanography, UC San Diego In the first global assessment of its kind, a science team led by researchers at Scripps Institution of Oceanography at UC San Diego has produced a landmark report on the impact of fishing on a group of fish known to protect the health of coral reefs. The report, published in the journal Proceedings of the Royal Society B (Biological Sciences), offers key data for setting management and conservation targets to protect and preserve fragile...

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...
