FIG. 2.

Stacked bar plot representing the distribution of sequences by phylum in the freshwater lake sequence database. Sequences were taxonomically classified by the RDP classifier (February 2010) (222) and were required to have 75% classifier confidence to be included as a representative of a phylum. Sequences with <75% confidence were termed unclassified. Phyla listed are present in both bar plots but are listed on only one side to aid in the visualization of the plots. a, the phylum Proteobacteria was split into its representative classes for sequences with a ≥75% confidence score at the class taxonomic assignment and unknown Proteobacteria for those sequences with confidence scores of <75%.
