Bacterial species associated with the protein-rich canned diet. A Volcano plot showing differential abundance of bacterial species in the protein-rich canned diet group between d 13 vs. d 27. Each dot is a bacterial species and dots are colored by phylum. Positive values in x-axis represent species that had higher relative abundance after fiber diet was administered for 14 d (d 27) relative to baseline. Negative values in the x-axis represent species that decreased in abundance in the protein-rich canned diet relative to the baseline. The horizontal dotted line represents significance threshold of FDR adjusted P < 0.01 obtained from DESeq2 and the two vertical lines differentiate the species with log2 fold change in abundance. Species with FDR adjusted P < 0.01 and absolute log2 fold change > 2 were considered statistically significant.
