Characterization of bacteria assemblage patterns based on taxa abundance and occurrence frequency model. (a). The taxa ecological category, taxa proportion to all detected taxa, and the average abundance of the taxa ecological category at different taxonomic levels (i.e., phylum, genus and species). (b), (c), (d), The best fitted model for average taxa abundance and occurrence frequency of different ecological communities (b: Fecal and Mucosal community; c: Fecal community; d: Gut Mucosal community)
