Relationships between log transformed VP/BP and four bacterial diversity indices.

<p>The figure shows the results of the relationships between log transformed VP/BP (viruses μg C⁻¹) and four bacterial diversity indices (A) OTU richness, <i>S</i>, (B) evenness, <i>E</i>, (C) the Shannon-Wiener diversity index, <i>H</i>, and (D) the Simpson's index of diversity, <i>D</i>. Individual dots represent the data obtained for individual treatments in the experiments conducted in December (Control: open circle, V: open triangle, P: open diamond, P+V: open square) and February (Control: closed circle, V: closed triangle, P: closed diamond, P+V: closed square). Solid and dashed lines are quadratic regressions (QM) and additive regression (AM) of <i>S</i>, <i>E</i>, <i>H</i> and <i>D</i> on log VP/BP.
