Townsville, Australia — Australian scientists have discovered coral reefs have an addiction to “junk food” and order symbiotic algae to produce it. James Cook University researchers said the symbiosis between coral, a primitive animal, and zooxanthellae — tiny one-celled plants — has not only built the largest [...]
A healthy fish population could be the key to ensuring coral reefs survive the impacts of climate change, pollution, overfishing and other threats. Australian scientists found that some fish act as “lawnmowers”, keeping coral free of kelp and unwanted algae. At a briefing to parliamentarians in Canberra, they said protected [...]
Once I would have thought that a ridiculous question. Yet today, if we assemble all the best science we have, the answer can at best be “maybe”.
It may seem preposterous that the greatest coral reef in the world – the biggest structure made by life on Earth – could be seriously (I mean genuinely [...]

When the going gets hot, corals can kick out heat-sensitive strains of symbiotic algae and take on a type that can withstand higher temperatures. This could mean certain reefs will be less susceptible to global warming than had been thought.
Like most other hard coral species, Acropora millepora, [...]
Several hundred years ago, the coral reefs of the Caribbean had up to six times more fish than they have today, according to a study published Wednesday.
The estimate is made by US scientists poring over the fate of the Caribbean monk seal, a fish-loving mammal driven to [...]
Terrie Klinger is starting to wonder about the future of kelp sex. It’s a delicate business in the best of times, and the 21st century is putting marine life to the acid test.
Klinger, of the University of Washington in Seattle, studies the winged and bull kelps that stretch rubbery garlands up from the seafloor [...]
Two dominant coral species have built a good chunk of the Caribbean reef, and their ability to grow quickly may help the region’s coral reefs keep pace with rising sea levels caused by global warming, researchers say.
The endangered staghorn and elkhorn corals grow about 10 times faster than [...]
Marine scientists have found that once fish hatch they use sound to find a home on a coral reef.
But the scientists say warming sea temperatures are affecting the hearing of fish and making them lose their way home.
Dr Steve Simpson from the University [...]
AIMS Media Release, 5th March 2008
Worrying signs that warmer seawater combined with a possible change in the ocean’s acid balance may be curtailing the growth of an important reef-building coral species have been documented by a research team from AIMS in Townsville.
The paper, published in the journal Global [...]
