Networks representing sample/OTU interaction.

<p>In both networks edge visibility (line width and opacity) is enhanced based on eweights, to better highlight the most relevant connections. A: sample nodes are shown according to grapevine cultivar (yellow: Chardonnay; blue: Merlot), OTU nodes are white, with edges indicated according to pest management type (red: IPM; green: organic production). B: sample nodes are indicated according to pest management type (red: IPM; green: organic production), OTU nodes are white, with edges indicated according to taxonomic assignment at phylum level (colour legend as for <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0112763#pone-0112763-g003" target="_blank">Fig. 3</a>). C: zoomed in view of <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0112763#pone-0112763-g004" target="_blank">Figure 4B</a>, with eweight significance for edge visibility emphasised.
