ThetaYC () measures the dissimilarity between the structures of two communities, where S_T is the total number of OTUs in communities μ and ν, μ_i and ν_i is the relative abundance of OTU i in community μ and ν, respectively. A matrix of pairwise thetaYC-based distances among all samples was calculated for PCoA analysis.
