Two temperate corals are tolerant to low pH regardless of previous exposure to natural CO2 vents
International audience Ocean acidification is perceived to be a major threat for many calcifying organisms, including scleractinian corals. Here we investigate (1) whether past exposure to low pH environments associated with CO2 vents could increase corals tolerance to low pH and (2) whether zooxant...
