Relative versus absolute abundances of microbial phyla in the crane gut microbiota. Phylum-level gut microbial community composition among all 15 species of cranes (n = 2 to 4 individuals per species). (a) Standard approach using rarefied ASV tables to estimate the relative abundance of bacterial phyla. (b) Mean microbial abundance estimates based on un-rarefied, microbial density-corrected ASV tables. Only the five most abundant microbial phyla are presented, with less abundant phyla pooled into ‘other'. (Online version in colour.)
