Meta-analysis of publically available 16S pyrosequencing datasets.

Datasets obtained from the SRA, VAMPS, and MG-RAST. The 16S rRNA hypervariable region assessed in each study is noted in brackets. Raw data was processed as described in the Materials and Methods section and each dataset screened for the presence of Zetaproteobacteria. N indicates the number of samples; nseqs the total number of reads; Sobs the total number of OTUs.*Alpha-diversity estimates based on sub-sampled pyrotag reads. 1/D, Inverse Simpson Index; Q, Q-statistic; d, Berger-Parker Index.†Unpublished datasets used with permission from A.-L.
