Figure 3

Variations in the relative abundances of six dominating OTUs detected at consecutive locations within the DWDS. The medians of 16S rRNA gene copies per OTU that were measured over a 5-month period are shown using 100% stacked bars for each consecutive location (A–F). OTUs with >5% relative abundance at the start of the DWDS are shown in shades of green, whereas OTUs with >5% relative abundance at the end of the DWDS are shown in shades of blue. All other OTUs with <5% relative abundance per sampled location were grouped together to ease visualization and are shown in grey.
