Figure 3
NMDS plots showing the variation in beta diversity between sex and locations (based on Bray-Curtis dissimilarities), according to (a) 18S rRNA gene, (b) plant ITS2 region, (c) fungal ITS2 region and (d) 16S rRNA gene sequences from caribou fecal DNA. Arrows in panel d) indicate correlations between the NMDS space and richness of various components of the diet (i.e., number of ASVs assigned to lichens belonging to the Crustose, Epiphytic Foliose, Epiphytic Fruticose, and Foliose growth forms; number of ASVs assigned to Herbaceous, Non-vascular, or Lignified plants) and parasites (total number of ASVs assigned to a parasite genus; number of ASVs assigned to the Blastocystis and Entamoeba genera). Only correlations that were identified as significant (p < 0.05) by the envfit function are shown (see Supplementary Table S6E for envfit results of all variables tested).
