Impact of medium-term exposure to elevated pCO2 levels on the physiological energetics of the mussel Mytilus chilensis ...
This study evaluated the impact of medium-term exposure to elevated pCO2 levels (750-1200 ppm) on the physiological processes of juvenile Mytilus chilensis mussels over a period of 70 d in a mesocosm system. Three equilibration tanks filled with filtered seawater were adjusted to three pCO2 levels:...
