||Determination of the proportion of radioisotop-labeled bacterioplankton
biomass which was assimilated by protists
||P.224 right column 3rd paragraph: "Aplastidic protists assimilated bacterioplankton biomass at a rate equivalent to 1.5–5.0 average bacterioplankton cells per protist cell per hour (Fig. 1a). Being specialized bacterivores, aplastidic protists had the highest bacterivory rates among planktonic protists both in the surface mixed layer and the thermocline: on average it was 13 times higher (P < 0.001) than small plastidic protists, 8.3 times higher (P < 0.005) than medium plastidic protists and 3.9 times higher (P < 0.001) than large plastidic protists in the temperate waters."
