From: Host habitat is the major determinant of the gut microbiome of fish
KEGG categories derived from the 16S rRNA sequences of the fish gut microbiome by PICRUSt. a PCoA of the binary Jaccard dissimilarity of the functional profiles (ANOSIM, R = 0.37, p < 0.001). b Box-and-whisker plots of the relative abundance of the selected KOs for samples from two different habitats determined by the LEfSe analysis (LDA score > 3.0). The center line shows the median, the boxes cover the 25th to 75th percentiles, the whiskers extend to 1.5× the interquartile range, and the outer points are outliers. Asterisks indicate significant differences between freshwater and seawater fish according to a two-tailed Mann–Whitney U test. **p < 0.01; ***p < 0.001. c Bar plot of the AUC of PRC for random forest classifiers for various discriminative factors of functional profiles of the fish gut. FWF freshwater fish, SWF seawater fish
