Abstract

<p>The increase of the atmospheric carbon dioxide (CO2) concentration after the industrial revolution caused global climate change. During the last several decades, coral reef ecosys tems have been devastated by the mass-scale coral bleaching events caused by abnormally high seawater temperature in summer. In addition, increased atmospheric CO2 dissolves in the ocean, acts as an acid and finally decreases the pH level of seawater. This phenomenon, known as ocean acidification, is now being considered as a future threat to the calcifying organisms in coral reef ecosystems. In this review, we summarize basic backgrounds of ocean acidification as well as its potential impacts on coral reef calcifiers. Together with the distinctive mechanisms of calcification among specific groups, we review the impacts of ocean acidification on major reef-builders such as scleractinian corals, calcareous red algae and reef-dwelling foraminifera. Finally, we point out some recently-recognized problems in acidified seawater experiments as well as the future direction of this research field.</p>
