Bacterial mock community samples (n = 117) over time. a Taxonomic composition of bacterial mock community samples over the course approximately 2 years shown at the family level. Labeled boxes along the bottom denote individual sequencing runs. Only taxa with an average abundance of at least 1% are shown. b Principal coordinates analysis (PCoA) of bacterial mock community samples using Bray-Curtis distances. Numbers in brackets denote percent of variation explained. c Bray-Curtis distances (boxplots) and intraclass correlation coefficients (ICC) (line plots) stratified by sequencing run. ICC values are shown as means. d Heatmap of the coefficient of variation (CV) values for individual bacterial genera across sequencing runs. Grayscale cells on the left indicate mean relative abundances for each genus (also given as percentages in parentheses)
