Comparative Transcriptomics Reveals Patterns of Adaptive Evolution Associated with Depth and Age Within Marine Rockfishes (Sebastes).
Article in The Journal of heredity, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

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 adaptive evolution. De novo assemblies from these transcriptomes were used to identify 3867 orthologous clusters, and genes subject to positive selection were identified based on all 5 species, depth, and lifespan. Within all our analyses, we identified hemoglobin subunit α to be under strong positive selection and is associated with the depth of occurrence. In our lifespan analysis we identified immune function genes under positive selection in association with maximum lifespan. This study provides insight on the molecular evolution of rockfishes and these candidate genes may provide a better understanding of how these subgenera radiated within the Northeast Pacific.
