乱開発や水温の上昇などの気候変動により危機に瀕している世界のサンゴ礁は、移植や調査・モニタリングなどの保全の取り組み無しでは近い未来に絶滅する恐れがあることが指摘されています。改訂新版は温暖化で世界のサンゴ礁の半分を死滅させた2015-16年の海洋熱波の問題も盛り込み、多様な微生物が高い密度で生息するサンゴ礁の複雑な生態系について最新の研究を踏まえ、地球にとって不可欠な健全な生態系の維持について考察します。
New to this Edition:
Coral reefs are among the most beautiful, and most diverse, of ecosystems. Early seafarers were wary of them, naturalists were confused by them, yet many coastal people benefited greatly from these mysterious rocky structures that grew up to the surface of the sea. They have been rich in their supply of food, and they provided a breakwater from storms and high waves to countless coastal communities that developed from their protection. Their scale is enormous and their value high. Found in countless locations around the world, from the Indo-Pacific coral reef province to the Caribbean and Australia, they support both marine and human life.
But today coral reefs are in trouble, with many dying or suffering from over-exploitation, pollution, and the warming and acidification of the oceans. Understanding reefs, their conservation and management, is vital, and so is conveying this to authority if we are to preserve these remarkable ecosystems. In this Very Short Introduction Charles Sheppard describes the complex structure and interdependencies of a reef, how reefs have evolved, the diversity of marine life that they support, and their importance to the human population who live beside them. This new edition describes the latest research on the complex symbioses of coral animals with microorganisms. It also highlights the scale of the challenge facing our reefs today, following recent ocean heatwaves - part of wider climate disruption - that killed half the world's reefs, and considers what can be done to preserve these essential and vibrant ecosystems.
