A glimmer of hope for corals as baby reef-builders cope with acidifying oceans

[font size=5]A glimmer of hope for corals as baby reef-builders cope with acidifying oceans[/font]
[font size=3]While the threat of coral bleaching as a result of climate change poses a serious risk to the future of coral reefs world wide, new research has found that some baby corals may be able to cope with the negative effects of ocean acidification.
Ocean acidification, which is a direct consequence of increased atmospheric carbon dioxide levels, is expected to have a deleterious effect on many marine species over the next century.
An international team examining the impact of ocean acidification on coral has found that a key reef-building coral can, over a relatively short period of time, acclimate to a doubling of atmospheric carbon dioxide levels.
…
“We found that, whereas 3 days of exposure to high CO[font size=1]2[/font] disrupts formation of the coral skeleton, within nine days the baby corals had re-adjusted their gene expression to pre-exposure levels. Longer exposure seems to be less detrimental to coral health than we had assumed based on shorter-term studies,” Dr Aurelie Moya says.
