a
Only the phyla that were represented in at least 0.8% of the total community after normalizing all of the samples to 99,618 reads per sample are shown. Phyla were attributed from the OTUs at a similarity threshold of 97%.
b
Calculated as the arithmetic mean proportion across 100 samples from 100 sites.
