Ocean acidification affects growth but not nutritional quality of the seaweed Fucus vesiculosus (Phaeophyceae, Fucales)

A brown seaweed (Fucus vesiculosus) grew more slowly in ocean acidification conditions. Consumption of the seaweed by an isopod (Idotea emarginata) was not affected by ocean acidification or temperature. However, reduced growth of the seaweed at high CO2 concentrations might reduce its capability to recover from intense herbivory.
