  • Norderhaug, K. M.; Angles d'Auriac, M. B.; Fagerli, C. W.; Gundersen, H.; Christie, H.; Dahl, K.; Hobæk, A. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    We compared the genetic differentiation in the green sea urchin Strongylocentrotus droebachiensis from discrete populations on the NE Atlantic coast. By using eight recently developed microsatellite markers, genetic structure ...
  • Haddeland, Peter Jørgen Tønnessen; Junge, Claudia; Serbezov, Dimitar; Vøllestad, Leif Asbjørn (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Knowing the breeding system of a species is important in order to understand individual variation in reproductive success. Large variation in reproductive success and thus reproductive skew strongly impacts on the effective ...
  • Khalsa, Siri-Dharma Kaur (Master thesis / Masteroppgave, 2013)
    Sorghum is ranked the fifth most produced food crop in the world, and is a dietary staple for over 500 million people in over 30 countries. It is the second most produced food crop in Africa, where cultivation of local ...
  • Olsen, Luka Natassja (Master thesis / Masteroppgave, 2015)
    Section Cochlearia (Brassicaceae) includes highly polymorphic species complexes with regard to ploidal level, ecological adaptation and distribution. Low levels of chloroplast DNA divergence suggest that taxa most likely ...
  • Gustafsson, A Lovisa S; Skrede, Inger; Rowe, Heather C.; Gussarova, Galina; Borgen, Liv; Rieseberg, Loren; Brochmann, Christian; Parisod, Christian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
    Crossing experiments indicate that hybrid sterility barriers frequently have developed within diploid, circumpolar plant species of the genus Draba. To gain insight into the rapid evolution of postzygotic reproductive ...
  • Evankow, Ann Marie (Master thesis / Masteroppgave, 2015)
    Various stressors such as higher temperatures, grazing by sea urchins, and anthropogenic effects may threaten kelp forests around the world. Conservation efforts can benefit from an understanding of current and historic ...
  • Skage, Morten; Barth, Julia Maria Isis; Jentoft, Sissel; Øverli, Øyvind; Jakobsen, Kjetill Sigurd (Research report / Forskningsrapport / PublishedVersion, 2017)
    Formålet med denne undersøkelsen var å identifisere mulige krysninger mellom hund og ulv i dagens skandinaviske ulvebestand. I tillegg ønsket vi å finne ut i hvor stor grad det er mulig å gjenkjenne innblanding av hund i ...
  • Jalal, Marwa (Doctoral thesis / Doktoravhandling, 2013)
    The relationship between temperature and body size has attracted wide interest since the “Bergmann's rule” was introduced. While this rule originally dealt with endotherms, later studies have focussed ectotherms, including ...
  • Barth, Julia Maria Isis; Berg, Paul Ragnar; Jonsson, Per R; Bonanomi, Sara; Corell, Hanna; Hemmer-Hansen, Jakob; Jakobsen, Kjetill Sigurd; Johannesson, Kerstin; Jorde, Per Erik; Knutsen, Halvor; Moksnes, Per-Olav; Star, Bastiaan; Stenseth, Nils Christian; Svedang, Henrik; Jentoft, Sissel; Andre, Carl (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Adaptation to local conditions is a fundamental process in evolution; however, mechanisms maintaining local adaptation despite high gene flow are still poorly understood. Marine ecosystems provide a wide array of diverse ...
  • Alfsnes, Kristian; Leinaas, Hans Petter; Hessen, Dag Olav (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Despite the major role of genome size for physiology, ecology, and evolution, there is still mixed evidence with regard to proximate and ultimate drivers. The main causes of large genome size are proliferation of noncoding ...
  • Nyhus, Erik Sanderud (Master thesis / Masteroppgave, 2017)
  • Tørresen, Ole K; Brieuc, Marine S O; Solbakken, Monica H; Sørhus, Elin; Nederbragt, Alexander J; Jakobsen, Kjetill S; Meier, Sonnich; Edvardsen, Rolf B; Jentoft, Sissel (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Background Increased availability of genome assemblies for non-model organisms has resulted in invaluable biological and genomic insight into numerous vertebrates, including teleosts. Sequencing of the ...
  • Guellil, Meriam; Kersten, Oliver; Namouchi, Amine; Bauer, Egil Lindhart; Derrick, Michael; Jensen, Anne Østergaard; Stenseth, Nils Christian; Bramanti, Barbara (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Louse-borne relapsing fever was one of the major diseases affecting Western human populations, with its last major pandemic killing millions after World War I. Despite the major role fevers have played in epidemic events ...
  • Star, Bastiaan; Tørresen, Ole Kristian; Nederbragt, Alexander Johan; Jakobsen, Kjetill Sigurd; Pampoulie, Christophe; Jentoft, Sissel (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    A variety of sex determination mechanisms can be observed in evolutionary divergent teleosts. Sex determination is genetic in Atlantic cod (Gadus morhua), however the genomic location or size of its sex-locus is unknown. ...
  • Runemark, Anna; Fernández, Laura Piñeiro; Eroukhmanoff, Fabrice; Sætre, Glenn-Peter (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Hybridization is increasingly recognized as a potent evolutionary force. Although additive genetic variation and novel combinations of parental genes theoretically increase the potential for hybrid species to adapt, few ...
  • Barth, Julia Maria Isis; Damerau, Malte; Matschiner, Michael; Jentoft, Sissel; Hanel, Reinhold (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Recent developments in the field of genomics have provided new and powerful insights into population structure and dynamics that are essential for the conservation of biological diversity. As a commercially highly valuable ...
  • Berg, Paul R. (Doctoral thesis / Doktoravhandling, 2017)
    The core of this thesis has been to address the genomic basis that underlies adaptation to environmental differences in the marine environment. We use Atlantic cod (Gadus morhua L.) to enhance our understanding of several ...
  • Elgvin, Tore Oldeide; Trier, Cassandra Nicole; Tørresen, Ole Kristian; Hagen, Ingerid; Lien, Sigbjørn; Nederbragt, Alexander Johan; Ravinet, Mark Simon Paul; Jensen, Henrik; Sætre, Glenn-Peter (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Hybridization is widespread in nature and, in some instances, can result in the formation of a new hybrid species. We investigate the genetic foundation of this poorly understood process through whole-genome analysis of ...
