Fig. 6: Diurnal oscillations do not decay with age.

a–c Diurnal oscillations of 16 focus genera in a) young meerkats (<1 year old; n = 385). b adult meerkats (1–5 years old; n = 627); and (c) particularly old meerkats (>5 years old; n = 97). Zero represents the taxa mean and sample distributions are indicated by the histograms. d–h Model estimates and 95% confidence intervals for (d) Clostridium (sensu stricto 1); (e) Bacteroides; (f) Paeniclostridium, (g) Cellulomonas, and (h) Raoultibacter, split by age category (blue = young; grey = adult; red = old).
