Table 2 By host comparison of phylogenetic diversity in speargrasses species and bulk sand

From: Rhizosheath microbial community assembly of sympatric desert speargrasses is independent of the plant host

  1. Faiths’ phylogenetic distance per SV (PD/SV), net relatedness index (NRI) and nearest taxon index (NTI) have been used as metrics to evaluate bacterial and fungal alpha phylogenetic diversities. Lowercase in parenthesis indicated the results of post hoc multiple comparison (Newman-Keuls test) among plant species
  2. *Communities that are significantly structured at the p < 0.05 level
