  • Evolution of Hemoglobin Genes in Codfishes Influenced by Ocean Depth 
    Baalsrud, Helle Tessand; Voje, Kjetil L.; Tørresen, Ole Kristian; Solbakken, Monica Hongrø; Matschiner, Michael; Malmstrøm, Martin; Hanel, Reinhold; Salzburger, Walter; Jakobsen, Kjetill Sigurd; Jentoft, Sissel (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Understanding the genetic basis of adaptation is one of the main enigmas of evolutionary biology. Among vertebrates, hemoglobin has been well documented as a key trait for adaptation to different environments. Here, we ...
  • Genomic stability through time despite decades of exploitation in cod on both sides of the Atlantic 
    Pinksy, Malin L; Eikeset, Anne Maria; Helmerson, Cecilia; Bradbury, Ian R.; Bentzen, Paul; Morris, Corey; Gondek, Agata; Baalsrud, Helle Tessand; Brieuc, Marine Servane Ono; Kjesbu, Olav Sigurd; Godiksen, Jane Aanestad; Barth, Julia Maria Isis; Matschiner, Michael; Stenseth, Nils Christian; Jakobsen, Kjetill Sigurd; Jentoft, Sissel; Star, Bastiaan (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    The mode and extent of rapid evolution and genomic change in response to human harvesting are key conservation issues. Although experiments and models have shown a high potential for both genetic and phenotypic change in ...
  • Historical demographic processes dominate genetic variation in ancient Atlantic cod mitogenomes 
    Martinez Garcia, Lourdes; Ferrari, Giada; Oosting, Tom; Ballantyne, Rachel; van der Jagt, Inge; Ystgaard, Ingrid; Harland, Jennifer; Nicholson, Rebecca; Hamilton-Dyer, Sheila; Baalsrud, Helle Tessand; Brieuc, Marine Servane Ono; Atmore, Lane; Burns, Finlay; Schmölcke, Ulrich; Jakobsen, Kjetill Sigurd; Jentoft, Sissel; Orton, David; Hufthammer, Anne Karin; Barrett, James; Star, Bastiaan (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Ancient DNA (aDNA) approaches have been successfully used to infer the long-term impacts of climate change, domestication, and human exploitation in a range of terrestrial species. Nonetheless, studies investigating such ...
  • De novo gene evolution of antifreeze glycoproteins in codfishes revealed by whole genome sequence data 
    Baalsrud, Helle Tessand; Tørresen, Ole Kristian; Solbakken, Monica Hongrø; Salzburger, Walter; Hanel, Reinhold; Jakobsen, Kjetill Sigurd; Jentoft, Sissel (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    New genes can arise through duplication of a pre-existing gene or de novo from non-coding DNA, providing raw material for evolution of new functions in response to a changing environment. A prime example is the independent ...
  • Supergene origin and maintenance in Atlantic cod 
    Matschiner, Michael; Barth, Julia Maria Isis; Tørresen, Ole K.; Star, Bastiaan; Baalsrud, Helle Tessand; Brieuc, Marine Servane Ono; Pampoulie, Christophe; Bradbury, Ian; Jakobsen, Kjetill Sigurd; Jentoft, Sissel (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Abstract Supergenes are sets of genes that are inherited as a single marker and encode complex phenotypes through their joint action. They are identified in an increasing number of organisms, yet their origins and evolution ...
  • The Genome of the Great Gerbil Reveals Species-Specific Duplication of an MHCII Gene 
    Nilsson, Pernille; Solbakken, Monica Hongrø; Schmid, Boris Valentijn; Orr, Russell; Lv, Ruichen; Cui, Yujun; Song, Yajun; Zhang, Yujiang; Baalsrud, Helle Tessand; Tørresen, Ole K.; Stenseth, Nils Christian; Yang, Ruifu; Jakobsen, Kjetill Sigurd; Easterday, William Ryan; Jentoft, Sissel (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Abstract The great gerbil (Rhombomys opimus) is a social rodent living in permanent, complex burrow systems distributed throughout Central Asia, where it serves as the main host of several important vector-borne ...
  • Variola virus genome sequenced from an eighteenth-century museum specimen supports the recent origin of smallpox 
    Ferrari, Giada; Neukamm, Judith; Baalsrud, Helle Tessand; Breidenstein, Abagail; Ravinet, Mark; Phillips, Carina; Rühli, Frank; Bouwman, Abigail; Schuenemann, Verena J. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Smallpox, caused by the variola virus (VARV), was a highly virulent disease with high mortality rates causing a major threat for global human health until its successful eradication in 1980. Despite previously published ...
