Corals respond to changing ocean conditions by altering regulation of the DNA message

2016-01-08 00:02:00| Climate Ark Climate Change & Global Warming Newsfeed

ScienceDaily: If an ocean gets too acidic for a coral's liking, it can't just swim away and find a nicer place to live. So how can corals survive in changing waters? Coral reefs sustain fisheries that feed millions of people, provide protection to coastlines from storms, and bolster economies through tourism. But with climate change altering ocean conditions important for healthy coral, the future of coral reefs is unclear. Dr. Hollie Putnam, a National Science Foundation Ocean Sciences Post-Doctoral Fellow,...

Growing corals bathe themselves in acid w/out suffering damage

New Scientist: Acidic water may be a sign of healthy corals, says a new study, muddying the waters still further on our understanding of how coral reefs might react to climate change. Andreas Andersson of the Scripps Institution of Oceanography in San Diego, California, and his colleagues carefully monitored a coral reef in Bermuda for five years, and found that spikes in acidity were linked to increased reef growth. "At first we were really puzzled by this," says Andersson. "It`s completely the opposite...

Creating corals that can survive climate change

2015-10-20 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Washington Post: Keyhole Reef is one of dozens of small reefs rising abruptly from the depths of Kaneohe Bay, one of Hawaiis most scenic places. The water around it is sapphire blue, and bright schools of tang and triggerfish flit over its surface. But the reef is showing troubling signs of stress these days because of climate change. Here and there along the steep face of the reef, clumps of coral have turned stark white. This bleaching means the coral has begun to eject the micro-algae that normally live within...

Self-regulating corals protect skeletons against ocean acidification

2015-10-09 19:02:00| Climate Ark Climate Change & Global Warming Newsfeed

ScienceDaily: Scientists from the ARC Centre of Excellence for Coral Reef Studies (Coral CoE) have found a species of coral living in a dynamic reef system, which is able to protect itself from the impact of ocean acidification. Ocean acidification, caused by rising CO2, is one of the greatest long-term challenges facing reefs. It reduces coral's ability to form their skeletons and build reef structures. Now Coral CoE researchers from the University of Western Australia and the University of Queensland have...
