Diversity (richness) of taxa and relationship between richness of bacterial genera and resistance genes expressed per 10 million reads. a Richness of bacterial genera is presented with the median (central black horizontal line); 25th and 75th percentiles (box) and whiskers extending from each end of the box to the most extreme values within 1.5 times the interquartile range from the respective end. Whiskers data points beyond this range are displayed as small black circles. b Genus richness versus richness of antibiotic resistance genes (Spearman’s correlation coefficient = 0.073, p = 0.0319). c Genus richness versus richness of biocide/metal resistance genes (Spearman’s correlation coefficient = 0.462, p < 0.001). Richness values were log-transformed before performing Spearman’s rank correlation. A value of 1 was added to the richness matrix to avoid zeros in log-transformed richness values in the correlation test
