    • Physiological Responses of Mesodiniummajor to Irradiance, Prey Concentration and Prey Starvation 

      Drumm, Kristine; Norlin, Andreas; Kim, Miran; Altenburger, Andreas; Hansen, Per Juel (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-18)
      Ciliates within the <i>Mesodinium rubrum/Mesodinium major</i> species complex harbor chloroplasts and other cell organelles from specific cryptophyte species. <i>Mesodinium major</i> was recently described, and new studies indicate that blooms of <i>M. major</i> are just as common as blooms of <i>M. rubrum</i>. Despite this, the physiology of <i>M. major</i> has never been studied and compared to ...
    • Pan-Arctic suitable habitat model for Greenland halibut 

      Vihtakari, Mikko; Hordoir, Robinson; Treble, Margret A; Bryan, Meaghan D.; Elvarsson, Bjarki; Nogueira, Adriana; Hallfredsson, Elvar H.; Christiansen, Jørgen Schou; Albert, Ole Thomas (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-08)
      Deep-sea marine fishes support important fisheries but estimates of their distributions are often incomplete as the data behind them may reflect fishing practices, access rights, or political boundaries, rather than actual geographic distributions. We use a simple suitable habitat model based on bottom depth, temperature, and salinity to estimate the potential distribution of Greenland halibut ...
    • Increased complement activation 3 to 6 h after trauma is a predictor of prolonged mechanical ventilation and multiple organ dysfunction syndrome: a prospective observational study 

      Rognes, Ingrid Nygren; Pischke, Søren Erik; Ottestad, William; Røislien, Jo; Berg, Jens Petter; Johnson, Christina; Eken, Torsten; Mollnes, Tom Eirik (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-08)
      Background - Complement activation is a central mechanism in systemic inflammation and remote organ dysfunction following major trauma. Data on temporal changes of complement activation early after injury is largely missing. We aimed to describe in detail the kinetics of complement activation in individual trauma patients from admission to 10 days after injury, and the association with trauma ...
    • Increased Local Inflammatory Response to MOC31PE Immunotoxin After Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy 

      Thorgersen, Ebbe Billmann; Asvall, Jørund; Frøysnes, Ida Storhaug; Schjalm, Camilla; Larsen, Stein Gunnar; Dueland, Svein; Andersson, Yvonne; Fodstad, Øystein; Mollnes, Tom Eirik; Flatmark, Kjersti (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-21)
      Background - Despite extensive cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC), most patients with resectable peritoneal metastases from colorectal cancer experience disease relapse. MOC31PE immunotoxin is being explored as a novel treatment option for these patients. MOC31PE targets the cancer-associated epithelial cell adhesion molecule, and kills cancer cells by ...
    • Environmental Controls of InSAR-Based Periglacial Ground Dynamics in a Sub-Arctic Landscape 

      Rouyet, L.; Karjalainen, Olli; Niittynen, P.; Aalto, Juha; Luoto, Miska; Lauknes, T.R.; Larsen, Y.; Hjort, J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-10)
      Periglacial environments are characterized by highly dynamic landscapes. Freezing and thawing lead to ground movement, associated with cryoturbation and solifluction. These processes are sensitive to climate change and variably distributed depending on multiple environmental factors. In this study, we used multi-geometry Sentinel-1 Synthetic Aperture Radar Interferometry (InSAR) to investigate the ...
    • The kaolinite shuttle links the Great Oxidation and Lomagundi events 

      Hao, Weiduo; Mänd, Kaarel; Li, Yuhao; Alessi, Daniel S.; Somelar, Peeter; Moussavou, Mathieu; Romashkin, Alexander E.; Lepland, Aivo; Kirsimäe, Kalle; Planavsky, Noah J.; Konhauser, Kurt O. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-19)
      The ~2.22–2.06 Ga Lomagundi Event was the longest positive carbon isotope excursion in Earth’s history and is commonly interpreted to reflect perturbations in continental weathering and the phosphorous cycle. Previous models have focused on mechanisms of increasing phosphorous solubilization during weathering without focusing on transport to the oceans and its dispersion in seawater. Building from ...
    • Midtrophic fish feeding modes at the poles: an ecomorphological comparison of polar cod (Boreogadus saida) and Antarctic silverfish (Pleuragramma antarctica) 

      Carlig, Erica; Christiansen, Jørgen Schou; Blasi, Davide Di; Ferrando, Sara; Pisano, Eva; Vacchi, Marino; O'Driscoll, Richard L.; Ghigliotti, Laura (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-20)
      The polar cod (Boreogadus saida) and the Antarctic silverfish (Pleuragramma antarctica) are pelagic fish endemic to the Arctic and Antarctica sea, respectively. Both species are abundant and play a central role as midtrophic wasp-waist species in polar ecosystems. Due to their biological and ecological characteristics (small size, complex life histories, relatively short generation cycles, movement ...
    • Business incubator management and entrepreneur collaboration with R&D milieus: Does the regional context matter? 

      Aarstad, Jarle; Jakobsen, Stig Erik; Foss, Lene (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-05)
      We study whether business incubator management collaboration with R&D milieus affects incubated entrepreneurs to also collaborate with R&D milieus in different regional contexts. Empirically, we analyse 281 Norwegian entrepreneurs in 32 different business incubators. Incubator collaboration with R&D milieus increases entrepreneur collaboration with R&D milieus in sparsely but not densely populated ...
    • Seasonal dynamics and life histories of three sympatric species of Pseudocalanus in two Svalbard fjords 

      Ershova, Elizaveta A; Nyeggen, Margot U.; Yurikova, Daria A.; Søreide, Janne E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-10)
      Small copepods are the most diverse and numerous group in high-latitude zooplankton, yet our knowledge of important species remains poor because of the difficulties involved in correct species identification. In this study, we use a molecular method of identification, a species-specific polymerase chain reaction, to provide the first description of the seasonal dynamics and life histories of the ...
    • Grad av tillit og kjennskap til norsk vannforvaltning 

      Fedreheim, Gunn Elin; Goes, Sander Bernardus (Journal article; Tidsskriftartikkel; Peer reviewed, 2021)
      Denne artikkelen analyserer et nordnorsk utvalg på 511 personer sin tillit til fylkeskommunen som vannregionmyndighet og kommunen som vannforvalter. Vi finner at til tross for utvalgets lave kjennskap til vannforvaltningen, har de høy grad av tillit til både vannregionmyndighetene og vannforvalterne. Vår antakelse er at dette skyldes at nordmenn tradisjonelt sett har høy tillit til politiske ...

      Bolstad, Ingeborg; Lien, Lars; Bramness, Jørgen G. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-31)
      Attention deficit hyperactivity disorder (ADHD) and post-traumatic stress disorder (PTSD) are more common in alcohol use disorder (AUD) patients than in the general population. Still, there is a lack of knowledge about the relationship between the two conditions in these patients. The main objective of this study was to examine the prevalence of ADHD symptoms, and the relationship between ADHD ...
    • Knowing and doing: The development of information literacy measures to assess knowledge and practice 

      Nierenberg, Ellen; Låg, Torstein; Dahl, Tove I. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-08)
      This study touches upon three major themes in the field of information literacy (IL): the assessment of IL, the association between IL knowledge and skills, and the dimensionality of the IL construct. Three quantitative measures were developed and tested with several samples of university students to assess knowledge and skills for core facets of IL. These measures are freely available, applicable ...
    • When different logics meet: the crisis communication of a national head coach in elite football 

      Andersen, Trine Lise; Moldenæs, Turid; Ronglan, Lars Tore (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-29)
      Through a longitudinal study of how a national head coach in men’s football defended and explained persistent losses, the following questions were addressed: What was the content of the media criticism, how did the coach react and why, and how did the media react to his response? Despite persistent losses, the coach praised his team and never admitted having done something wrong. The media, in turn, ...
    • The preservation of ancient DNA in archaeological fish bone 

      Ferrari, Giada; Cuevas, Angelica; Gondek, Agata; Ballantyne, Rachel; Kersten, Oliver; Palsdottir, Albina Hulda; van der Jagt, Inge; Hufthammer, Anne Karin; Ystgaard, Ingrid; Wickler, Stephen; Bigelow, Gerald F; Harland, Jennifer; Nicholson, Rebecca; Orton, David; Clavel, Benoît; Boessenkool, Sanne; Barrett, James H; Star, Bastiaan (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-09)
      The field of ancient DNA is dominated by studies focusing on terrestrial vertebrates. This taxonomic bias limits our understanding of endogenous DNA preservation for species with different bone physiology, such as teleost fish. Teleost bone is typically brittle, porous, lightweight, and is characterized by a lack of bone remodeling during growth. All of these factors potentially affect DNA preservation. ...
    • Approaching the boundary problem: Self-determination, inclusion, and the unpuzzling of transboundary conflicts 

      Spitzer, Aaron John (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-03)
      In recent decades, decisionmakers have increasingly faced conflicts juxtaposing demands for self-determination and inclusion. Political theorists term this juxtaposition “the boundary problem.” They have offered normative solutions, especially for “just inclusion,” proposing what states owe to exogenous individuals like migrants and refugees. Meanwhile, as I show, legal scholars have developed ...
    • User-centred Design of a Digital Care Plan for Patients and Professionals in Cross-organisational Teams 

      Smaradottir, Berglind; Severinsen, Gro-Hilde; Steinsbekk, Aslak; Berntsen, Gro Karine Rosvold (Journal article; Tidsskriftartikkel; Peer reviewed, 2021)
      Care for patients with multimorbidity and long-term complex needs is costly and with demographic changes this group is growing. The research project Dignity Care addresses how to improve the care for this patient group by studying how a conceptual shared digital care plan for complex clinical pathways can guide and support cross-organisational care teams. This paper presents the user-centred design ...
    • First observations of Polar Mesospheric Echoes at both 31MHz and 53.5MHz over Svalbard (78.2°N 15.1°E) 

      Hall, Chris; Adami, Chris; Tsutsumi, Masaki (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-09)
      During summer 2020, observations of the mesosphere using a 53.5 MHz radar on Svalbard, at 78.2°N 15.1°E, revealed the well-known Polar Mesospheric Summer Echoes (PMSE). At the same time, a co-located meteor detection radar, operating at 31 MHz detected corresponding echoes very distinct from those associated with meteor trails. Comparing as many days as possible during 2020, incontestable evidence ...
    • Molecular dietary analyses of western capercaillies (Tetrao urogallus) reveal a diverse diet 

      Chua, Physilia Y. S.; Lammers, Youri; Menoni, Emmanuel; Ekrem, Torbjørn; Bohmann, Kristine; Boessenkool, Sanne; Alsos, Inger Greve (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-13)
      Conservation strategies centered around species habitat protection rely on species’ dietary information. One species at the focal point of conservation efforts is the herbivorous grouse, the western capercaillie (Tetrao urogallus), which is an indicator species for forest biodiversity conservation. Non-molecular means used to study their diet are time-consuming and at low taxonomic resolution. This ...
