TABLE 3.

Community diversity by sample site as measured by Shannon, Chao, dominance, and evenness metrics^a

Sample site	Shannon index	Chao index	Dominance index	Evenness index
Glottis	1.28 ± 1.11	31.9 ± 19.81	0.53 ± 0.37	0.19 ± 0.10
Subglottis	2.75 ± 0.76	75.42 ± 94.35	0.15 ± 0.11	0.35 ± 0.13
Supraglottis	2.77 ± 0.83	140.85 ± 168.44	0.17 ± 0.12	0.26 ± 0.09
Trachea	2.51 ± 0.58	64.8 ± 30.29	0.18 ± 0.12	0.30 ± 0.11

^aMean 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.
