Rank abundance of bacterial species during phases of colonization. Rank abundance was determined from the relative abundance of each species during each phase of microbial colonization. Taxonomic identification and metabolic analysis was completed based on genome reconstructions from the shotgun-sequenced microbial community. The colonization process is broken into two distinct phases defined by the dominance of either (a) facultative anaerobes during phase one or (b) obligate anaerobes during phase two.
