Principal coordinate analyses (PCoAs) of all the bacterial communities. These PCoAs are based on Jaccard index after a Hellinger transformation. a Comparison between water bacterial community and whitefish intestinal microbiota. Although the water bacterial communities come from five different lakes at different depths, all water samples are represented by a blue point. Each lake analyzed is represented by a different color: Cliff Lake (red), East Lake (blue), Indian Lake (orange), Témiscouata Lake (green), and Webster Lake (purple), and each whitefish species is represented by symbols: dwarf (circle) and normal (cross). b–f Comparison between dwarf and normal microbiota for each lake. Cliff Lake, East Lake, Indian Pond, Témiscouata Lake, and Webster Lakes are represented by b, c, d, e, and f, respectively. Each whitefish species is represented by different symbols: dwarf (circle) and normal (cross); ellipses of 95% confidence are illustrated and were done with dataEllips using R car package. The red and green ellipses represent the dwarf and normal species, respectively
