Venn diagram comparing the OPF membership found in three whalebone microbial communities (AGZO, n = 38,981 peptide fragments; AHAA, n = 36,165; and AHAI, n = 33,199). Below each community name is the Chao1 richness estimate and the 95% confidence interval for that community. We estimated the richness of the overlapping regions based on the pairwise SA,B Chao shared richness estimates between the three communities and by pooling two communities and estimating the shared fraction with the third community. These estimates are provided on the right side of the figure.
