FIGURE 2

Non-metric multidimensional scaling (nMDS) of bacterial community composition of P. margaritifera at the OTU-level. Each symbol colour denotes one tissue (Gill = red, Gonad = pink, Byssus gland = gold, Haemolymph = grey, Mantle = green, Muscle = purple, Mucus = blue, Gut = cyan), ellipses are drawn around each group’s centroid (95%). P-values indicate significant differences in bacterial community composition between tissues (PERMANOVA and ANOSIM tests).
