Variation in biofilm community composition at the floodplain level.

<p>Principal Coordinates Analysis (PCoA) of biofilm (i.e., bacteria and cyanobacteria), bacteria, and cyanobacteria community assemblies (based on Bray–Curtis distances among OTUs abundances) as related to the four different riverine floodplains (Color coding as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0144303#pone.0144303.g002" target="_blank">Fig 2</a>). Percentage of the diversity distribution explained by each axes is indicated on the figure.
