Table 3.
Beta diversity (Bray–Curtis) values for microbiomes. BCST represents the degree of within vs. between population structure, and beta diversity represents the mean distance to the species centroid. High values of BCST indicate higher levels of population structure (i.e. more distinct population clusters on an ordination).
