TABLE 3

Community diversity by sample site as measured by Shannon, Chao, dominance, and evenness metricsa

Sample siteShannon indexChao indexDominance indexEvenness index
Glottis1.28 ± 1.1131.9 ± 19.810.53 ± 0.370.19 ± 0.10
Subglottis2.75 ± 0.7675.42 ± 94.350.15 ± 0.110.35 ± 0.13
Supraglottis2.77 ± 0.83140.85 ± 168.440.17 ± 0.120.26 ± 0.09
Trachea2.51 ± 0.5864.8 ± 30.290.18 ± 0.120.30 ± 0.11
  • a Mean value ± standard deviation was obtained for each index relative to sample site. Reduced diversity in community members is noted for the glottis region compared to that of other regions sampled.
