Microzooplankton grazing upon picoplankton : the effect of future carbon dioxide levels in the ocean
Impacts of ocean acidification on marine biota were observed in a wide range of marine systems. However, there is no abundant literature about the effect of a future high pCO2 scenario on microzooplankton grazing in the ocean. Here, we used two different mesocosms under the Bioacid/Kosmos Project (G...
