The goal of the dCod-project is to combine the competencies in environmental toxicology, biology, bioinformatics and mathematics across the traditional department boundaries, to create a deeper understanding of cods' adaptations and reactions to stressors in the environment. Building on the thoroughly studies and mapping of the cod genome at UiO and the long research traditions on cod at the Department of Biology at UiB, the dCod project will expand our knowledge with methods based on genomics; ...
