Figure 4

Principal coordinate analysis (PCoA) showing clustering of individual skin and intestinal microbiome communities based on Bray-Curtis dissimilarity. For every skin-associated community represented, a counterpart intestine-associated community from the same S. alpinus individual is shown. Legend refers to the sample type and environment of where an S. alpinus individual was caught and includes skin microbiomes from freshwater sites (n = 30), and from saline sites (n = 30), as well as intestinal microbiomes from freshwater sites (n = 30) and from saline sites (n = 30). Fresh refers to lake and river sites sampled in winter and spring while saline refers to sea shoreline locations sampled in autumn during the annual char run.
