Table 1 Metrics comparing the richness, evenness and diversity of bacterial symbiont communities

From: Feeding cessation alters host morphology and bacterial communities in the ascidian Pseudodistoma crucigaster

Diversity metric Measure Active Resting P-value
Richness Observed OTUs (Sobs) 28 ± 5 62 ± 10 <0.05*
  Expected OTUs (SChao1) 33 ± 6 87 ± 19 <0.05*
Evenness Simpson Index (E1/D) 0.10 ± 0.02 0.05 ± 0.01 0.076
  Smith & Wilson (Evar) 0.48 ± 0.02 0.38 ± 0.02 <0.05*
Diversity Inverse Simpson (1/D) 3.2 ± 1.2 2.9 ± 0.1 0.819
  Shannon Index (H) 1.4 ± 0.4 1.9 ± 0.1 0.294
  1. Statistical comparisons (Student’s t-test) between communities in active and resting colonies of the ascidian P. crucigaster are shown, with significant values indicated with asterisks (*)
