Symbiont population structure for a SOX and b MOX. Top left triangle: intra-sample π and symbiont fixation index (FST) based on SNVs. Lower right triangle: α- and β-diversity based on reconstructed strains. Rows and columns are labeled by sample name, sample location, and shell size. Heatmap hierarchical clustering is based on Euclidean distance of FST. a SOX: mean pairwise FST is 0.618. Two groups show an extreme degree of isolation: mean pairwise FST of group composed of M, N, R, is 0.313; mean pairwise FST of group composed of L, O, P, Q is 0.308; mean FST of sample pairs where one sample is M, N, or R and the other sample is L, O, P, or Q is 0.969. b MOX: mean pairwise FST is 0.495. The clustering displays two groups: mean pairwise β-diversity of group composed of P, Q, S is 0.0033; mean pairwise β-diversity of group composed of A, C, J, L, M, R is 0.012
