FIGURE 5.

Niche overlap level and community compositional shifts. The magnitude of community compositional changes observed in the microbiome was regressed on each niche overlap index obtained based on the shotgun metagenomic analysis. Niche overlap index at each time point and time-series shifts in community structure (Bray–Curtis β-diversity between present and next time points through the time-series of the shotgun metagenomic data) are shown along horizontal and vertical axes, respectively. The regression lines are shown with 95% confidence intervals.
