Biomineralization changes with food supply confer juvenile scallops ( Argopecten purpuratus) resistance to ocean acidification
Abstract Future ocean acidification ( OA ) will affect physiological traits of marine species, with calcifying species being particularly vulnerable. As OA entails high energy demands, particularly during the rapid juvenile growth phase, food supply may play a key role in the response of marine orga...
