| Community | Diversity estimate

|||||
|---|---|---|---|---|---|---|
| No. of distinct sequences | No. of OTUsa | Shannon-Weiner index | Gene diversity | Nucleotide diversity | θ(π)b | |
| Mouth | 59 | 123 (93, 180)c | 3.18 | 0.958 ± 0.004 | 0.32 ± 0.15 | 341.7 ± 162.1 |
| Gut | 63 | 135 (110, 170) | 3.50 | 0.960 ± 0.004 | 0.30 ± 0.14 | 154.8 ± 73.6 |
a
Data from reference 5.
b
The values are not directly comparable because different numbers of nucleotide positions were examined.
c
The values in parentheses are the 95% confidence limits.
