Poolseq of exome enriched Sebastes samples

The goals of this study were to identify genomic regions associated with depth divergence in rockfishes (genus Sebastes). Many closely related rockfish species are distributed along a depth gradient. We examined pooled samples that were enriched for exome sequences to identify genomic regions in two species pairs of rockfishes (S. chlorostictus/S. rosenblatti and S. crocotulus/S. miniatus). We were able to identify numerous regions of divergence in the S. chlorostictus/S. rosenblatti, some of which contained genes related to neurosensory pathways. The patterns were not as clear for the S. crocotulus/S. miniatus pair. Demographic modelling suggested a similar history of divergence for the two species pairs.
