    Activation of endoplasmic reticulum (ER) stress/the unfolded protein response (UPR) has been linked to cancer, but the molecular mechanisms are poorly understood and there is a paucity of reagents to translate this for ...
  • Is bigger better? A study of competitive abilities in bryozoa in deep time. 
    Ramsfjell, Mali Hamre (Master thesis / Masteroppgave, 2016)
  • Is chain length in phytoplankton regulated to evade predation? 
    Bjærke, Oda; Jonsson, Per R.; Alam, Asraful; Selander, Erik (Journal article / Tidsskriftartikkel / SubmittedVersion, 2015)
    Formation of cell chains in phytoplankton is ecologically important, but no single factor driving the evolution of chain formation has been identified. Chain length in the diatom Skeletonema marinoi declines in response ...
  • Is Colobus guereza gallarum a valid endemic Ethiopian taxon?
