Figure 2. A) The honey bee microbiota of the midgut and ileum. Color-coded bars represent relative abundance corrected by species-specific 16S rRNA gene copy number. Black represents diversity abundance, OTU’s 11-1230. B and C) Principal component analysis of the midgut and Ileum respectively based on the most abundant OTUs. Clustered groups of points contain similar groupings of taxa with similar ratio abundances, and longer OTU vectors result from greater variation in CLR scores.
