95% COI^e	112-193	126-271	174-427

Calculations were based on operational taxonomic units formed at an evolutionary distance of <0.03 (or ~97% similarity).
^aS, number of operational taxonomic units observed.
^bN, number of sequences.
^cRichness = (number of singleton OTUs-1)/logN. The maximum value is (N-1)/logN. The observed/maximum possible value is reported.
^dShannon diversity index (H).
^e95% confidence interval for Chao1 estimator.
