Diversity indices of denitrifying bacterial communities determined from RFLP group membership using Chao and Shannon (<i>H</i>') metrics or by comparative sequence analysis for phylogenetic diversity (PD), net relatedness index (NRI), and nearest taxon index (NTI) based on <i>nosZ</i> gene clones from each soil community (n = 3).
