title: Data from: Adaptive genetic variation distinguishes Chilean blue mussels (Mytilus chilensis) from different marine environments

description: Chilean mussel populations have been thought to be panmictic with limited
 genetic structure. Genotyping-by-sequencing approaches have enabled
 investigation of genome-wide variation that may better distinguish
 populations that have evolved in different environments. We investigated
 neutral and adaptive genetic variation in Mytilus from six locations in
 southern Chile with 1,240 SNP obtained with RAD-seq. Differentiation among
 locations with 891 neutral SNPs was low (FST = 0.005). Higher
 differentiation was obtained with a panel of 58 putative outlier SNPs (FST
 = 0.114) indicating the potential for local adaptation. This panel
 identified clusters of genetically related individuals and demonstrated
 that much of the differentiation (~92%) could be attributed to the three
 major regions and environments: extreme conditions in Patagonia, inner bay
 influenced by aquaculture (Reloncaví́), and outer bay (Chiloé Island).
 Patagonia samples were most distinct, but additional analysis carried out
 excluding this collection also revealed adaptive divergence between inner
 and outer bay samples. The four locations within Reloncaví́ area were most
 similar with all panels of markers, likely due to similar environments,
 high gene flow by aquaculture practices and low geographic distance.
 However, fine scale structure could be detected when analyses included
 only this zone. Our results and the SNP markers developed will be a
 powerful tool supporting management and programs of this harvested
 species.
