    <p>In (A) all treatments are included, while (B) represents the 0, 3 and 7-day treatments. The vector overlays correspond to multiple partial correlations of the predictor variables with the dbRDA axes. Hypoxia depicts the duration of hypoxia (days) while S1–3 depicts the PCA scores used to represent the benthic community.</p

    <p>(A) abundance (B) biomass (C) number of species (D) total number of trait modalities present (filled squares, primary y-axis, r<sup>2 = </sup>0.93, p<0.001) and the average number of species within trait modalities (white circles, secondary y-axis, r<sup>2 = </sup>0.86, p<0.001) and (E) the community bioturbation potential (BP<sub>c</sub>). <i>Mya arenaria</i> is excluded from the biomass data. Non-linear regression curves were fitted to the plotted data (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0044920#pone.0044920.s005" target="_blank">Table S2</a>). For presentation, the x-axes are log (x + 1) transformed.</p

    <p>(A) Number of stressed and/or dead <i>M. balthica</i> on the sediment surface with increasing duration of hypoxia. A nonlinear regression curve was fitted to the replicate values (r<sup>2 = </sup>0.92, p<0.0001, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0044920#pone.0044920.s005" target="_blank">Table S2</a>). The dotted horizontal line represents the number of <i>M. balthica</i> found at depth in undisturbed sediments. (B) The reburial rate of <i>M. balthica</i> after 0, 3 and 7 days of hypoxia. 20 bivalves were included for each treatment (tested in the laboratory). The x-axes are log (x + 1) transformed.</p
