  • Ecological transitions, like shifts between habitats, can shape genomic variation. By analyzing genomes from 66 sea catfish species, this study finds that younger freshwater lineages show more positive selection and body shape disparity, with prolactin gene adaptations likely aiding their colonization and radiation.

  • In this genomic study on Alpine whitefish radiations, the authors reveal details on the genetic architecture underlying the repeated eco-morphological diversification and the role of hybridization in the evolution of endemic whitefish species.

  • Genomic analysis of an Alpine whitefish radiation before and after human-driven lake eutrophication that led to the extinction of one species through hybridization shows that substantial parts of the genome of the extinct species persist within surviving species due to introgressive hybridization.
