Figure 3. Bacterial alpha-diversity (3 indices; Chao, Shannon and Invsimpson) in muskox adults (n=6) and calves (n=4) presented on box-whisker plots. No significant mean differences were detected between adults and calves (t-tests; Chao, p = 0.56; Shannon, p = 0.45; Invsimpson, p = 0.43) but homogeneity of variance Fligner-Killeen test; (“+” means p < 0.05, “++” means p < 0.01; Chao, p = 0.03; Shannon, p = 0.0013; Invsimpson, p = 0.02).
