Extended Data Fig. 6

a,b, Mean-squared displacements of log-relative OTU abundances <δ2(Δt)> as a function of time Δt. Dashed lines represent regression fits to the data using the equation of abnormal diffusion <δ2(Δt)>∝Δt2H, where H is the Hurst exponent characterizing the diffusion process. The diffusion Hurst exponents are H = 0.07 ± 0.03, 0.10 ± 0.04, 0.08 ± 0.02, 0.1 ± 0.07 for humans A, B, M3, and F4, respectively, and H = 0.08 ± 0.02, 0.19 ± 0.02 for the LFPP and HFHS mice (mean ± s.d., n = 6 equal subsamples of the data for humans and n = 3 animals for mice, see Methods).
