Relative abundance of taxon groups above 5% at five taxonomic ranks. Each boxplot in the figures indicated the range of bacteria genera observations in each sample, with the box denoting the interquartile range (IQR) between the first and third quartiles (i.e., 25th and 75th percentiles, respectively) and the vertical line inside the box defined the median. In order to better show the difference in bacterial species between the groups, more than 5% of all samples (six groups), in any one group, were counted (from phylum to genera) and plotted
