Fig. 2

Examples of taxonomic perturbations, their corresponding functional shifts, and the associated response curves. The taxonomic perturbation and functional shift magnitudes generated for a single vaginal (a) and a single gut (b) community. Each point represents a single perturbation. The red lines indicate the taxa-function response curve fit to these points. The response curves for all vaginal (c) and gut (d) communities are overlaid to compare general body site trends. Green and blue lines represent the mean response curve for all vaginal and gut communities respectively. The robustness factor distributions associated with these response curves are shown as violin plots with inlaid boxplots for attenuation (e) and buffering (f). The width of the violin plot indicates the density of robustness factor values, the middle of the box displays the median robustness factor value, the upper and lower edges of the box represent the 75th and 25th percentiles, respectively, and the whiskers extend to 1.5 times the inner quartile range (range between the 75th and 25th percentiles) past either end of the box. Outliers are shown as individual black circles
