FIG 2.

Four core assignment methods identify different sets of core taxa from abundance data in a study of human microbiomes (top row) HMP, (Human Microbiome Project [52]) and (bottom row) Arabidopsis thaliana, (Lundberg et al. [10]). Additionally, the sets of core and non-core taxa do not exhibit categorically distinguishable abundances. The outlined bins denote whether taxa in the bin were included within the core. Fill color corresponds to taxa count.
