Figure 6. Effect of grazers on the level of reduction of organic cell constituents.
This figure shows the overall level of reduction of organic constituents in (A) Tetraselmis suecica, (B) Thalassiosira weissflogii and (C) Synechococcus sp. cells cultured in media containing 1, 5, 10 or 30 mM SO4 2- and in the presence of either Euplotes sp. or Acartia tonsa. Error bars show standard deviation calculated from at least four independent replicates. Histograms on top of which the same letter appears represent means that are not statistically different; different letters identify means that are significantly different (p > 0.05).
