European sea bass show behavioural resilience to near-future ocean acidification
Ocean acidification (OA)-caused by rising concentrations of carbon dioxide (CO2)-is thought to be a major threat to marine ecosystems and has been shown to induce behavioural alterations in fish. Here we show behavioural resilience to near-future OA in a commercially important and migratory marine f...

Ocean acidification (OA)-caused by rising concentrations of carbon dioxide (CO2)-is thought to be a major threat to marine ecosystems and has been shown to induce behavioural alterations in fish.
