Coral reefs - 50 most recentCoral reef parks established by locals more effective than government reserves 7/31/2006 Coral reef marine protected areas established by local people for traditional use can be far more effective at protecting fish and wildlife than reserves set up by governments expressly for conservation purposes, according to a study by the New York-based Wildlife Conservation Society (WCS) and other groups. NASA satellite images key to coral reef survey 7/31/2006 A first-of-its-kind survey of how well the world's coral reefs are being protected was made possible by a unique collection of NASA views from space. Some corals can adapt to ocean acidification 7/6/2006 While scientists warn that increasing ocean acidity will doom marine animals that build skeletons and structural elements out of calcium carbonate, new research has found that corals can change their skeletons, building them out of different minerals depending on the chemical composition of the seawater around them. However, the research provides further evidence that corals are extremely sensitive to rapid environmental change and will be negatively affected by increased carbon dioxide levels in the short-term. Increasingly acidic oceans damaging to marine life 7/5/2006 Carbon dioxide emissions are altering ocean chemistry and putting sea life at risk according to a new report released today. The report, "Impacts of Ocean Acidification on Coral Reefs and Other Marine Calcifiers," summarizes known effects of increased atmospheric carbon dioxide on marine organisms that produce calcium carbonate skeletal structures, such as corals. Oceans worldwide absorbed approximately 118 billion metric tons of carbon between 1800 and 1994 according to the report, resulting in increased ocean acidity, which reduces the availability of carbonate ions needed for the production of calcium carbonate structures. Genetic contact between reef fish across the 5000 km Pacific divide 7/5/2006 Reef fish share genetic connections across what Darwin termed an 'impassable barrier', 5000km of deep ocean separating the eastern and central Pacific, according to a report by Smithsonian scientists. Severe damage expected for Caribbean coral reefs in 2006 7/4/2006 Caribbean Sea temperatures have reached their annual high two months ahead of schedule according to a report from The Associated Press. Scientists are concerned that the region's coral reefs may suffer even worse damage than last year when 70 percent of coral was bleached in some areas. Climate change Madagascar's reefs escape damage from global warming 6/22/2006 A survey of coral along Madagascar's northeast coast suggests that they island's reef may have so far escaped the damaging effects of warmer ocean temperatures attributed to global climate change. Researchers from Conservation International (CI), a leading conservation group, found that the region's coral reefs have avoided the bleaching that has affected other Indian Ocean reefs. The scientists believe that cool water currents from adjacent deep ocean areas have helped offset the warming effects of climate change. Climate change World's coral reefs threatened by lack of effective protection 6/22/2006 Of the 18.7% of tropical coral reefs that lie within "Marine Protected Areas," less than 2% are extended protection complete with regulations on extraction, poaching and other major threats, according to an analysis published in Science Magazine on June 23. The research represents the first global assessment of the extent, effectiveness and gaps in coverage of coral reefs by MPAs. The team built a database of MPAs for 102 countries, including satellite imagery of reefs worldwide, and surveyed more than 1,000 MPA managers and scientists to determine the conservation performance of MPAs. Global warming may cause permanent damage to coral reefs 5/15/2006 Global warming has had a more devastating impact on coral reefs than previously believed says a new study published in the Proceedings of the National Academy of Sciences. The research, the first to show the long-term impact of rising sea temperatures on coral and fish communities, suggests that "large sections of coral reefs and much of the marine life they support may be wiped out for good," according to a news release from the University of Newcastle upon Tyne, an institution involved in the project. Climate change Corals may survive global warming by gorging themselves 4/26/2006 A new study published in Nature says some coral are able to survive bleaching events by gorging themselves. An experiment with Hawaiian corals showed that when bleached, one species sharply increased its intake of food, increasing the likelihood that it would survive elevated water temperatures. Climate change Recent Coral Bleaching at Great Barrier Reef 4/5/2006 An international team of scientists are working at a rapid pace to study environmental conditions behind the fast-acting and widespread coral bleaching currently plaguing Australia's Great Barrier Reef. NASA's satellite data supply scientists with near-real-time sea surface temperature and ocean color data to give them faster than ever insight into the impact coral bleaching can have on global ecology. Australia's Great Barrier Reef is a massive marine habitat system made up of 2,900 reefs spanning over 600 continental islands. Though coral reefs exist around the globe, researchers actually consider this network of reefs to be the center of the world's marine biodiversity, playing a critical role in human welfare, climate, and economics. Coral reefs are a multi-million dollar recreational destinations, and the Great Barrier Reef is an important part of Australia's economy. Climate change Reefs threatened by tsunami reconstruction 3/16/2006 Indian Ocean coral reefs that escaped serious damage are coming under increasing threat from reconstruction efforts in the region according to a new report from the international environmental groups, World Conservation Union and the Global Coral Reef Monitoring Network. Coral reefs and mangroves have high economic value 1/24/2006 Protecting coral reefs and mangrove forests makes economic sense according to a new report by the United Nations Environment Programme (UNEP). The report argues that conserving these ecosystems for the services they provide--from fisheries protection to erosion control to a source for medical compounds--is cost-effective relative to destroying them and substituting their role with man-made structures. Marine reserves improve health of coral reefs finds study 1/5/2006 It may be no surprise that marine reserves protect the fish that live in them, but now scientists from the University of Exeter have shown for the first time that they could also help improve the health of coral reefs. New resource documents Caribbean marine life of Bocas del Toro 12/27/2005 Coral reefs, coastal rainforest, land-grab, industrial bananas and organic cacao, mangroves, tourist boom, eclectic cultural mix: A Caribbean Journal of Science special issue presents the first scientific overview of the marine environment in Bocas del Toro Province. New online photographic guide to coral reef fish larvae unlocks secrets of young fish 12/13/2005 Coralreeffish.com, a coral reef fish research site, today announced the availability of a photographic web-guide to the late-stage larvae of coral reef fishes. The guide is aimed at both assisting researchers in identifying the myriad fish larvae that are caught in reef surveys and providing an overview of this intriguing, and often invisible, world to students and interested laymen. Coral reefs decimated by 2050, Great Barrier Reef's coral 95% dead 11/17/2005 Australia's Great Barrier Reef could lose 95 percent of its living coral by 2050 should ocean temperatures increase by the 1.5 degrees Celsius projected by climate scientists. The startling and controversial prediction, made last year in a report commissioned by the World Worldwide Fund for Nature (WWF) and the Queensland government, is just one of the dire scenarios forecast for reefs in the near future. The degradation and possible disappearance of these ecosystems would have profound socioeconomic ramifications as well as ecological impacts says Ove Hoegh-Guldberg, head of the University of Queensland's Centre for Marine Studies. Climate change Papua New Guinea adds 12 new protected areas 11/4/2005 The government of Papua New Guinea announced that it will gazette 12 new protected areas covering some of the country's most biologically diverse forests, wetlands and coral reefs. Satellite monitors health of coral reefs 10/5/2005 Australian researchers have found Envisat's MERIS sensor can detect coral bleaching down to ten metres deep. This means Envisat could potentially monitor impacted coral reefs worldwide on a twice-weekly basis. Divers to monitor health of coral reefs in the UAE 9/12/2005 The Emirates Diving Association is training its members and staff to monitor the health of the coral reefs and marine life in the UAE. In Fiji locals grow “live rock” for aquarium trade with university help 7/26/2005 In a unique project that combines environmental conservation, economic development and drug discovery research, scientists and policy experts led by the Georgia Institute of Technology are collaborating with the villagers of Tagaqe and the University of the South Pacific to explore, protect and generate income for islanders from their shallow fringing coral reef. Recordings of coral reef sounds attract fish 5/24/2005 Using recordings of reef sounds may increase reef fish stocks depleted by shipping traffic, underwater drilling and overfishing. Scientists have discovered that some species of young coral reef fish are lured back to home reefs by sounds they hear while still developing in the egg.
