Mean relative abundance of all 194 species per week; the 41 prominent species (mean > 5% in at least one donor x week group) are coloured and labelled, the others grey. Week 0 = donor sample (*_NA_0_1). 'All donors' = sample-weighted mean across all fecal samples pooled across donors. Bands are stacked by abundance at each week (largest on top).
