α and β diversity indices before (DI-0) and after 5 days of Dry Immersion (DI-5) in healthy men (n = 14). (a) α-diversity evaluated with the Observed, Chao1, Shannon and InvSimpson indices. The paired t-test did not find any significant difference between time points. (b) Individual α-diversity evaluated with the Observed, Chao1, Shannon and InvSimpson indices. (c) β-diversity analysis using the Jaccard (p = 0.998), Bray–Curtis (p = 0.997) and UniFrac (p = 0.999) indices indicated no difference between DI-0 and DI-5 in microbial OTU absence/presence, abundance, or phylogeny (PERMANOVA analysis). Data are mean ± SEM.
