First attempts in evaluating acidification effects on physiologicalresponses in Mytilus galloprovincialis
Increasing CO2 atmospheric concentration produced by human activities is responsible for both global warming and progressive acidification of oceans. Ocean acidification may affect calcareous structures of organisms, and modify their physiological performance, in particular survival, growth, feeding...
