Example of a novel, previously undescribed module of coexisting lineages. (A) Five distinct microbial lineages are shown; they belong to three different phyla and are defined at an OTU-clustering distance of 90% sequence identity at the 16S rRNA gene. The five lineages have been exclusively observed through environmentally sampled sequences and have not been named. (B) The table shows all occurrence counts of these lineages among our sampling data; the P-values indicated have been corrected for multiple testing, against the background of all lineages defined at 90%. Adjusted P-values (FDR; p) and odds ratios (or) are indicated. (*) The samples by Li et al.(2008) have been collected at distinct sites, covering a distance of more than 600 miles; collection was at different water depths and sampling dates. Investigators involved in unpublished work are as follows: E Julies, V Bruechert, and BM Fuchs; B Orcutt, SB Joye, S Kleindienst, K Knittel, A Ramette, A Rietz, V Samarkin, T Treude, and A Boetius; A Postec, R Warthmann, C Vaconcelos, K Hanselmann, and J McKenzie; Z Zhang, H Xiao, and X Tang.
