Comments P.39 left column:"Recent studies indicate that picoeucaryotes [<2µm] dominate the biomass and productivity of picophytoplankton in most regions of the world ocean (see Li 1995), except the central North Pacific where Prochlorococcus accounted for 64 % of biomass (primary source Campbell et al. 1994) and up to 44 % of gross primary production (primary source Vaulot 1995). The grazing of heterotrophic flagellates and ciliates on Prochlorococcus and other picoplankters is substantial."
