Disentangling structural genomic and behavioral barriers in a sea of connectivity
Barth, Julia Maria Isis; Villegas-Ríos, David; Freitas, Carla; Moland, Even; Star, Bastiaan; André, Carl; Knutsen, Halvor; Bradbury, Ian; Dierking, Jan; Petereit, Christoph; Righton, David; Metcalfe, Julian; Jakobsen, Kjetill Sigurd; Olsen, Esben Moland; Jentoft, Sissel (Journal article; Peer reviewed, 2019)Genetic divergence among populations arises through natural selection or drift and is counteracted by connectivity and gene flow. In sympatric populations, isolating mechanisms are thus needed to limit the homogenizing ... -
Evidence of hybridization between genetically distinct Baltic cod stocks during peak population abundance(s)
Helmerson, Cecilia; Weist, Peggy; Brieuc, Marine Servane Ono; Maurstad, Marius Filomeno; Schade, Franziska Maria; Dierking, Jan; Petereit, Christoph; Knutsen, Halvor; Metcalfe, Julian; Righton, David; André, Carl; Krumme, Uwe; Jentoft, Sissel; Hanel, Reinhold (Peer reviewed; Journal article, 2023)Range expansions can lead to increased contact of divergent populations, thus increasing the potential of hybridization events. Whether viable hybrids are produced will most likely depend on the level of genomic divergence ... -

Observations of cod behaviour reveal insights into the function and properties of the swimbladder under pressure
Kooij, Jeroen van der; Righton, David; Michalsen, Kathrine; Thorsteinsson, Vilhjalmur; Svedäng, Henrik; Neat, Francis (ICES CM documents, Working paper, 2006)Atlantic cod (Gadus morhua L.) is a highly adaptive boreal species with a broad distribution through different ecosystems in the North Atlantic. Diet, environmental factors and population dynamics vary enormously ... -
Thermal dynamics of ovarian maturation in Atlantic cod (Gadus Morhua)
Kjesbu, Olav Sigurd; Righton, David; Krüger-Johnsen, Maria; Thorsen, Anders; Michalsen, Kathrine; Fonn, Merete; Witthames, Peter R. (Journal article; Peer reviewed, 2010-03)The timing and success of spawning in marine fish are of fundamental importance to population persistence and distribution and, for commercial species, sustainability. Their physiological processes of reproduction are ... -
Thermal niche of Atlantic cod Gadus morhua: limits, tolerance and optima
Righton, David; Andersen, Ken Haste; Neat, Francis; Thorsteinsson, Vilhjalmur; Steingrund, P.; Svedäng, Henrik; Michalsen, Kathrine; Hinrichsen, Hans-Harald; Bendall, Victoria; Neuenfeldt, Stefan; Wright, Peter; Jonsson, Patrik; Huse, Geir; Kooij, Jeroen van der; Mosegaard, Henrik; Hüssy, Karin; Metcalfe, Julian D. (Journal article; Peer reviewed, 2010)Recent studies in the marine environment have suggested that the limited phenotypic plasticity of cold-adapted species such as Atlantic cod Gadus morhua L. will cause distributions to shift toward the poles in response to ... -
