LEfSe analyses of gut microbial populations of the four fish species studied. Taxonomic cladogram of different microbial communities. (a) Identified differentially abundant taxa among four groups (HE, PL, OM, and CA) by linear discriminant analysis effect size (LEfSe) (log 10 ≥ 3.0). (b) Cladogram indicating LEfSe results presenting the recognized OTUs distributed according to phylogenetic characteristics around the circle. The dots in the center show the OTUs at phylum level, whereas the outer circle of dots indicates the OTUs at species level. The color of the dots and sectors present the most abundant OTUs in the four fish species with different feeding habits. Yellow color indicates OTUs with similar abundance in all compartments. The colored sectors give information on phylum (full name in the outermost circle, given only for phylum showing groups, class, order, and family that were significantly different among feeding habits are shown at the right side).
