Beta diversity. a Jaccard algorithm (stress value = 0.137). Only the presence or absence of OTUs in the sample was considered, not the abundance. b Bray–Curtis algorithm (stress value = 0.096). Both the presence and absence of OTUs in the sample and the abundance were considered. c Unweighted-UniFrac algorithm (stress value = 0.064). It only considers whether the sequence was present in the community, not the abundance of the sequence. d Weighted-UniFrac algorithm (stress value = 0.069). It accounts for the abundance of sequences on the basis of unweighted UniFrac and was able to differentiate species abundance
