    • Risikofaktorer knyttet til mobbing, en kvantitativ studie- Risikofaktorer i Kvellomalen, og hvordan de predikerer/reduserer mobbing 

      Berg, Malin (Master thesis; Mastergradsoppgave, 2019-11-05)
      Mobbing er en velkjent faktor som truer skoletrivsel og skolefungering hos barn. Kvellomalen er den mest brukte beslutningsmalen hos den norske barneverntjenesten. En evaluering av Kvellomalen konkluderer med at skoletrivsel og fungering ikke etterspørres eksplisitt. Skoletrivsel og skolefungering er en av de viktigste prediktorene for hvordan barn i kontakt med barnevernet klarer seg senere i livet. ...
    • Publication practice in Taxonomy: Global inequalities and potential bias against negative results 

      Salvador, Rodrigo Brincalepe; Cavallari, Daniel caracanhas; Rands, Douglas; Tomotani, Barbara mizumo (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-01)
      There is broad recognition by practicing taxonomists that the field is going through a crisis, which has been dubbed the “taxonomic impediment”. There are many aspects involved in said crisis, but publication practices in taxonomy are often neglected or relegated to the backseat. We provide an initial foray into this topic via a worldwide survey with taxonomists, spanning all botanical and ...
    • Stress responses to repeated captures in a wild ungulate 

      Trondrud, Liv Monica; Ugland, Cassandra Regine; Ropstad, Erik; Loe, Leif Egil; Albon, Steve; Stien, Audun; Evans, Alina; Thorsby, Per Medbøe; Veiberg, Vebjørn; Irvine, R. Justin; Pigeon, Gabriel (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-29)
      While capture-mark-recapture studies provide essential individual-level data in ecology, repeated captures and handling may impact animal welfare and cause scientific bias. Evaluating the consequences of invasive methodologies should be an integral part of any study involving capture of live animals. We investigated short- and long-term stress responses to repeated captures within a winter on the ...
    • The root zone of graminoids: A niche for H2-consuming acetogens in a minerotrophic peatland 

      Meier, Anja B.; Oppermann, Sindy; Drake, Harold L.; Schmidt, Oliver (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-05)
      The importance of acetogens for H<sub>2</sub> turnover and overall anaerobic degradation in peatlands remains elusive. In the well-studied minerotrophic peatland fen Schlöppnerbrunnen, H<sub>2</sub>-consuming acetogens are conceptualized to be largely outcompeted by iron reducers, sulfate reducers, and hydrogenotrophic methanogens in bulk peat soil. However, in root zones of graminoids, fermenters ...
    • Trend effects on perceived avalanche hazard 

      Terum, Jens Andreas; Mannberg, Andrea; Hovem, Finn Kristoffer (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-30)
      Hazard-level forecasts constitute an important risk mitigation tool to reduce loss of economic values and human life. Avalanche forecasts represent an example of this. As for many other domains, avalanche risk is communicated using a color-coded, categorical risk scale aimed at informing the public about past, current, and future risk. We report the results from three experiments in which we ...

      Berries of the genus Vaccinium are highly valued health-beneficial superfoods, which are commonly subjected to adulteration and mixed with each other, or with other common berry species. A quantitative DNA-based method utilizing a chip-based digital polymerase chain reaction (dPCR) technique was developed for identifying and quantifying wild lingonberry (V. vitis-idaea) and cultivated American ...
    • Transcriptomes Suggest That Pinniped and Cetacean Brains Have a High Capacity for Aerobic Metabolism While Reducing Energy-Intensive Processes Such as Synaptic Transmission 

      Geßner, Cornelia; Krüger, Alena; Folkow, Lars; Fehrle, Wilfrid; Mikkelsen, Bjarni; Burmester, Thorsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-09)
      The mammalian brain is characterized by high energy expenditure and small energy reserves, making it dependent on continuous vascular oxygen and nutritional supply. The brain is therefore extremely vulnerable to hypoxia. While neurons of most terrestrial mammals suffer from irreversible damage after only short periods of hypoxia, neurons of the deep-diving hooded seal (Cystophora cristata) show ...
