Fig. 2From: Altered gut microbiota in female mice with persistent low body weights following removal of post-weaning chronic dietary restrictionAge explains more microbiota variability than diet and body weight. a The first two PCs from the PCA on the unweighted UniFrac distance matrix are plotted. Symbols represent data from individual diet regimens color-coded by sampling days. The main axes of the ellipses correspond to the PCs of the group with the heights and widths representing variances in the corresponding components. b The percentage of microbiota variability explained by age, diet type, Δbwt, and their combination (total) based on different UniFrac distances. UniFrac, GUniFrac, and WUniFrac represent unweighted, generalized (α = 0.5), and weighted UniFrac distance, respectively. Non-linear age effects are assumedBack to article page
