Pacific oysters do not compensate growth retardation following extreme acidification events
International audience Ocean acidification caused by anthropogenic carbon dioxide emissions alters the growth of marine calcifiers. Although the immediate effects of acidification from global ocean models have been well studied on calcifiers, their recovery capacity over a wide range of pH has never...

International audience Ocean acidification caused by anthropogenic carbon dioxide emissions alters the growth of marine calcifiers.
