Alpha Diversity. Top row: Number of OTUs observed in each cohort pre- (D0) and post-exposure (D5) for the indicated metal. Middle row: Faith’s Phylogenetic Diversity (PD) pre (D0) and post-exposure (D5). Bottom row: Shannon’s diversity index for each cohort pre- (D0) and post-exposure (D5) for the indicated metal. In each plot, color indicates dose level.
