Comparative Transcriptomics Reveals Patterns of Adaptive Evolution Associated with Depth and Age Within Marine Rockfishes (Sebastes).

ABSTRACT: The genetic underpinnings that contribute to ecological adaptation and speciation are not completely understood, especially within marine ecosystems. These evolutionary processes can be elucidated by studying adaptive radiations, because they provide replicates of divergence within a given environment or time-frame. Marine rockfishes (genus Sebastes) are an adaptive radiation and unique model system for studying adaptive evolution in the marine realm. We investigated molecular evolution associated with ecological (depth) and life history (lifespan) divergence in 2 closely related clades of Sebastes. Brain transcriptomes were sequenced via RNA-Seq from 3 species within the subgenus Pteropodus and a pair of related congeners from the subgenus Sebastosomus in order to identify patterns of ada
