Kompensationsvermögen von Mytilus edulis gegenüber mechanischem Stress und erhöhtem pCO2 - kombinierte transkriptomische, proteomische und physiologische Analysen
The CO2 content of the atmosphere is increasing since the onset of the industrial revolution. As a result, CO2 is taken up by the oceans, which leads to decreases in seawater pH and carbonate ion concentration [CO32-]. As calcifying organisms use CO32- to construct their skeletons, they are suggeste...
