Extended Data Fig. 8: Distributions of residence and return times of gut microbiota in humans and mice.
Distributions of residence and return times for a, human and b, mouse gut microbiota. Solid lines represent fits to the data using power laws with exponential tails of the form p(t)∝t−αe−λt. In humans, the power law exponents are αres = 2.3 ± 0.04, 2.2 ± 0.05, 2.2 ± 0.07, and 2.14 ± 0.08 for the residence times and αret = 1.1 ± 0.02, 0.15 ± 0.03, 1.2 ± 0.05, and 1.09 ± 0.07 for the return times (A, B, M3, F4 respectively; mean ± s.d., n = 6 equal subsamples of the data, see Methods). In mice, αres = 2.2 ± 0.04, 2.2 ± 0.03 and αret = 0.72 ± 0.03,0.67 ± 0.06 for the LFPP and HFHS diet groups, respectively (mean ± s.d., across n = 3 mice).
