Table S1. Mean percentage of sequence divergence (K2P corrected) within (dw, boldface on diagonal) and between (da off-diagonal) eastern Pacific Bathymodiolus mussels. Pairwise comparisons involving the S23 sample are highlighted in blue. The d values between northern and southern regions are highlighted in gray. Table S2. Simulation results for the STRUCTURE analysis of eastern Pacific Bathymodiolus mussels under correlated and uncorrelated allelic frequency models. The number of possible genotypic clusters, K, varied from one to eleven. The natural log of the probability of the data for a given value of K was averaged across the number of simulations (runs) per K. Bayes factors were estimated based on these averages.

Figure S3. Analysis of isolation-by-distance in B. thermophilus populations from north of the Easter Microplate. Open triangles are φST values estimated from mitochondrial sequences in the GAR and EPR (N13–S21) samples. Filled circles are FST values estimated from the combined nuclear loci in the GAR, and EPR (N13–S17) samples.
