    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 ...

  • Nesbø, Camilla Lothe; Charchuk, Rhianna; Pollo, Stephen M.J.; Budwill, Karen; Kublanov, Ilya V.; Haverkamp, Thomas Hendricus Augustus; Foght, Julia (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    The genus Mesotoga , the only described mesophilic Thermotogae lineage, is common in mesothermic anaerobic hydrocarbon‐rich environments. Besides mesophily, Mesotoga displays lineage‐specific phenotypes, such as no or ...
  • 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 ...
  • Ravinet, Mark; Yoshida, Kohta; Shigenobu, Shuji; Toyoda, Atsushi; Fujiyama, Asao; Kitano, Jun (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Speciation is a continuous process and analysis of species pairs at different stages of divergence provides insight into how it unfolds. Previous genomic studies on young species pairs have revealed peaks of divergence and ...
  • 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 ...
  • Mazzarella, Anna; Boessenkool, Sanne; Østbye, Kjartan; Vøllestad, Leif Asbjørn; Trucchi, Emiliano (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    Understanding the genetic basis of traits involved in adaptive divergence and speciation is one of the most fundamental objectives in evolutionary biology. Toward that end, we look for signatures of extreme plate loss in ...
  • Trier, Cassandra Nicole (Doctoral thesis / Doktoravhandling, 2018)
    The genomic landscape of a hybrid species is marked by alternating regions of parental inheritance and areas of genomic constraint which form reproductive barriers. A PhD candidate at the University of Oslo has explored ...
  • Mysterud, Atle; Stigum, Vetle Malmer; Jaarsma, Ryanne I.; Sprong, Hein (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Lyme borreliosis is the most common vector-borne zoonosis in the northern hemisphere, and the pathogens causing Lyme borreliosis have distinct, incompletely described transmission cycles involving multiple host groups. The ...
  • Hagenes, Eskild (Master thesis / Masteroppgave, 2014)
    Nanotechnology is a growing industry bringing with the increasing utilization of nanoparticles (NP). NPs are defined as particles with at least one dimension being smaller than 100 nm. They are an increasing concern because ...
