Average values and standard errors (in parenthesis) are shown. Different letters show significant differences between sites (Tukey′s HSD test, P < 0.05).

Calculation of richness and diversity estimators was based on OTU tables rarefied to the same sequencing depth of 11 000 sequences.

OTUs were defined as < 3% nucleotide sequence difference.
