  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Haukenes, Kjersti (Master thesis / Masteroppgave, 2013)
    Perfluorooctanoic acid (PFOA) and fluoranthene are organic pollutants with a widespread environmental occurrence. They are both present in the environment, and are known to concentrate and bioaccumulate in organisms, PFOA ...
  • Ellis, Charlie; Hodgson, DJ; Andre, Carl; Sørdalen, Tonje Knutsen; Knutsen, Halvor; Griffiths, Amber (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Decapod crustaceans exhibit considerable variation in fertilisation strategies, ranging from pervasive single paternity to the near-ubiquitous presence of multiple paternity, and such knowledge of mating systems and behaviour ...
  • Hessen, Dag Olav; Tombre, Ingunn; van Geest, Gerben; Alfsnes, Kristian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    Migratory connectivity by birds may mutually affect different ecosystems over large distances. Populations of geese overwintering in southern areas while breeding in high-latitude ecosystems have increased strongly over ...
  • Sareisian, Lena (Master thesis / Masteroppgave, 2014)
    Abstract It is not known whether exposure to persistent organic pollutants (POPs) cause epigenetic changes in marine mammals. Ringed seals are a key species at the higher trophic levels of arctic marine ecosystems, and may ...
  • Wik, Jonas Aakre (Master thesis / Masteroppgave, 2016)
    Background: Endothelial cells form a highly dynamic barrier between blood and tissues and can be activated in response to angiogenic and inflammatory stimuli. Endothelial cells rely on glycolysis for ATP production, and ...
  • Wilson, Greg; Brian, Jennifer; Cranston, Karen; Kitzes, Justin; Nederbragt, Alexander Johan; Teal, Tracy K (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Computers are now essential in all branches of science, but most researchers are never taught the equivalent of basic lab skills for research computing. As a result, data can get lost, analyses can take much longer than ...
  • Yang, Hong; Andersen, Tom; Dörsch, Peter; Tominaga, Koji; Thrane, Jan-Erik; Hessen, Dag Olav (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Boreal lakes are important net sources of greenhouse gases (GHGs). In this study we analyzed concentrations of CO2, CH4, N2O as well as O2, N2 and argon (Ar) from the epilimnion of 75 boreal lakes covering gradients in ...
