Relative abundance of the top 15 genera in fecal samples immediately before sacrifice. CD and WD bars represent the donor FMTs. All other bars represent 8 mice per group: Captive High (CH), Captive Low (CL), Wild High (WH) and Wild Low (WL). Each color represents a genus in proportion to its relative abundance in each group. We did not find differences between earlier timepoints and the final timepoint with regards to the genera presented here, thus we are showing genera in samples immediately before sacrifice to avoid redundancy.
