How species adapt to diverse environmental conditions is essential for understanding evolution and the maintenance of biodiversity. The European cisco ( Coregonus albula ) is a salmonid that occurs in both fresh and brackish water, and this together with the presence of sympatric spring‐ and autumn‐spawning lacustrine populations provides an opportunity for studying the genetics of adaptation in relation to salinity and timing...

The authors used museomics to reconstruct the mitochondrial genome from two individuals of the Moroccan, endemic and extinct trout, Salmo pallaryi . They further obtained partial data from 21 nuclear genes previously used for trout phylogenetic analyses. Phylogenetic analyses, including publicly available data from the mitochondrial control region and the cytochrome b gene, and the 21 nuclear genes, place S. pallaryi among oth...
