Abstract

産業革命以降の二酸化炭素(CO_2)排出量の増加は,地球規模での様々な気候変動を引き起こし,夏季の異常高海水温は,サンゴ白化現象を引き起こすことでサンゴ礁生態系に悪影響を及ぼしたことが知られている。加えて,増加した大気中CO_2が海水に溶け込み,酸として働くことで生じる海洋酸性化もまた,サンゴ礁生態系にとって大きな脅威であることが認識されつつある。本総説では,海洋酸性化が起こる仕組みと共に,海洋酸性化がサンゴ礁域の石灰化生物に与える影響についてのこれまでの知見を概説する。特に,サンゴ礁の主要な石灰化生物である造礁サンゴや紅藻サンゴモ,有孔虫に関しては,その石灰化機構を解説すると共に,海洋酸性化が及ぼす影響について調べた様々な研究例を取り上げる。また,これまでの研究から見えてきた海洋酸性化の生物への影響評価実験を行う上で注意すべき事項,そして今後必要となる研究の方向性についても述べたい。The increase of the atmospheric carbon dioxide (CO_2) concentration after the industrial revolution caused global climate change. During the last several decades, coral reef ecosystems have been devastated by the mass-scale coral bleaching events caused by abnormally high seawater temperature in summer. In addition, increased atmospheric CO_2dissolves 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.
