    The vertical distribution and migration of plankton organisms may have a large impact on their horizontal dispersal and distribution, and consequently on trophic interactions. In this study we used video-net profiling to ...
  • Fischer, Barbara; van Doorn, G. Sander; Dieckmann, Ulf; Taborsky, Barbara (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
    When organisms encounter environments that are heterogeneous in time, phenotypic plasticity is often favored by selection. The degree of such plasticity can vary during an organism’s lifetime, but the factors promoting ...

    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 ...
  • de la Cámara Peña, Marina (Master thesis / Masteroppgave, 2019)
    Human activities have historically influenced the evolution of other species. Dramatic modifications in land-use and extreme urbanization have increased not only the amount of species associated with human environments, ...

    Teleost fishes constitute the most species-rich vertebrate clade and exhibit extensive genetic and phenotypic variation, including diverse immune defense strategies. The genomic basis of a particularly aberrant strategy ...
  • Michalik, Marcin; Rydmark, Marcella Orwick; Habeck, Michael; Alva, Vikram; Arnold, Thomas; Linke, Dirk (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    An intimate interaction between a pair of amino acids, a tyrosine and glycine on neighboring β-strands, has been previously reported to be important for the structural stability of autotransporters. Here, we show that the ...
  • Orr, Russell; Stüken, Anke; Murray, Shauna A.; Jakobsen, Kjetill Sigurd (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)
    Saxitoxin and its derivatives are potent neurotoxins produced by several cyanobacteria and dinoflagellate species. SxtA is the initial enzyme in the biosynthesis of saxitoxin. The dinoflagellate full mRNA and partial genomic ...
  • Smeds, Linnea; Warmuth, Vera; Bolivar, Paulina; Uebbing, Severin; Burri, Reto; Suh, Alexander; Nater, Alexander; Bures, Stanislav; Garamszegi, Laszlo Z.; Hogner, Silje; Moreno, Juan; Qvarnström, Anna; Ruzic, Milan; Sæther, Stein Are; Sætre, Glenn-Peter; Torok, Janos; Ellegren, Hans (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    The typically repetitive nature of the sex-limited chromosome means that it is often excluded from or poorly covered in genome assemblies, hindering studies of evolutionary and population genomic processes in non-recombining ...
  • Bache-Mathiesen, Lena Kristin (Master thesis / Masteroppgave, 2015)
    Hybridization is increasingly recognized as a source of novel variation, but how hybridization can contribute to evolution is still not fully understood. Insights into the evolutionary potential of hybrid species, and the ...
  • Solbakken, Monica Hongrø; Tørresen, Ole Kristian; Nederbragt, Alexander Johan; Seppola, Marit; Gregers, Tone Fredsvik; Jakobsen, Kjetill Sigurd; Jentoft, Sissel (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    Genome sequencing of the teleost Atlantic cod demonstrated loss of the Major Histocompatibility Complex (MHC) class II, an extreme gene expansion of MHC class I and gene expansions and losses in the innate pattern recognition ...
