Relative abundance of major taxonomic groups in the Puget Sound samples and other selected metagenomes.Taxonomic groupings were based on BLASTX comparison to the NCBI taxonomy using MG-Rast [39] and ?50% identity and an alignment length ?50 amino acids. The ?other? category includes bacteria taxa present in <1% of sequences in all samples, eukaryotes and viruses. Shading is proportional to the relative abundance of each taxon within a metagenome. The cladogram was displayed using hierarchical clustering and the Euclidian distance metric. See Materials and Methods for references describing the additional metagenomes used for comparison. The open Sound locations cluster with other more saline environments including open and coastal ocean samples while the Marina and WWTP effluent samples cluster within a larger clade containing other freshwater and freshwater-impacted metagenomes.
