Differentiation of <i>Symbiodinium</i> communities between pools.

<p>NMDS biplots on Bray-Curtis dissimilarities are shown for water (A), sediment (B), and coral (C). Samples from pool 300 and pool 400 are represented by circles and triangles, respectively. Taxa are plotted in the same ordination space and colored by clade (A = green, C = yellow, D = purple, F = red, G = orange) to show their role in driving the differentiation between samples (e.g., clade D in association with sediment samples from pool 400). Three sediment samples are plotted with arrows indicating they lie outside the plot range. For corals, 90% confidence ellipses surround groups of species categorized qualitatively as low (< 0.4), intermediate (0.4–0.6), or high (> 0.6) overall dissimilarity (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0145099#pone.0145099.t001" target="_blank">Table 1</a>) to illustrate the range of observed variability in different coral species. Coral species whose symbiont communities were significantly different between pools (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0145099#pone.0145099.t001" target="_blank">Table 1</a>) are represented by filled symbols (gray = <i>Psammacora contigua</i>, black = <i>Pavona venosa</i>).
