FIGURE 3 Non-metric multidimensional scaling (NMDS) ordination of sampling sites according to community dissimilarity (Simpson dissimilarity index, βSIM), at ASV (left panel) and OTU (right panel) levels. Circles correspond to sampling sites, with circle size representing sample richness. The percentage of explained variation (R 2) and the significance of forest habitat type as grouping factor based on PERMANOVA are reported on the top of each plot. Colours and habitat codes as in Figure 1.
