Linear discriminate analyses of trophic specialist microbiota
We found that an excess of taxa in the family Burkholderiaceaebest discriminated all lab-reared scale-eater individuals in two
different lake populations from all other gut microbiome samples
(Figures 3-4; linear discriminant analysis log score = 4.85). In
addition, we found a deficiency of Vibrionales ,Vibrionaceae , and Vibrio in these scale-eater individuals
relative to all other gut samples (LDA log scores = -5.22, -5.22, and
-5.08, respectively; Figure 4). Similarly, we found an excess of taxa in
the family Rhodobacteraceae and class Planctomycetacia in
the molluscivores relative to all other gut samples (Figure 5; LDA log
scores of 4.39 and 4.37, respectively).
