Evolved differences in energy metabolism and growth dictate the impacts of ocean acidification on abalone aquaculture
Ocean acidification (OA) poses a major threat to marine ecosystems and shellfish aquaculture. A promising mitigation strategy is the identification and breeding of shellfish varieties exhibiting resilience to acidification stress. We experimentally compared the effects of OA on two populations of re...
