Figure 4. Differentially abundant OTUs within the gut of the mottled spinefoot rabbitfish (Siganus fuscescens) among (A) individual fish (n = 4), (B) gut locations (M, mid; H, hind), (C) gut sites (C, content; W, wall) and (D) gut sites within gut locations (MC, mid-content; MW, mid-wall; HC, hind-content; HW, hind-wall).

OTU abundances have been z-score transformed and thus show the number of standard deviations an OTUs abundance is from the mean abundance of that OTU.
