    • Future Arctic Ocean Seasonal Ice Zones and Implications for Pelagic-Benthic Coupling 

      Wassmann, Paul; Reigstad, Marit (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Despite concerns about rapid changes in Arctic Ocean physical forcing and ecosystem function, quantitative knowledge and time series are scarce. The number of reliable physical-biological coupled models and models based on remote sensing is small. To improve our comprehension of carbon flux in the most prominent Arctic Ocean feature, the seasonal ice zone, a possible first step is to evaluate how ...

      Jansson, Roland; Nilsson, Christer; Keskitalo, E. Carina H.; Viasova, Tatiana; Sutinen, Marja-Liisa; Moen, Jon; Chapin, Stuart; Bråthen, Kari Anne; Cabeza, Mar; Callaghan, Terry V.; van Oort, Bob; Dannevig, Halvor; Bay-Larsen, Ingrid Agathe; Ims, Rolf Anker; Aspholm, Paul Eric (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-09)
      Humans depend on services provided by ecosystems, and how services are affected by climate change is increasingly studied. Few studies, however, address changes likely to affect services from seminatural ecosystems. We analyzed ecosystem goods and services in natural and seminatural systems, specifically how they are expected to change as a result of projected climate change during the 21st ...

      The Arctic sea-ice-scape is rapidly transforming. Increasing light penetration will initiate earlier seasonal primary production. This earlier growing season may be accompanied by an increase in ice algae and phytoplankton biomass, augmenting the emission of dimethylsulfide and capture of carbon dioxide. Secondary production may also increase on the shelves, although the loss of sea ice exacerbates ...

      Vilas, Daniel; Coll, Marta; Pedersen, Torstein; Corrales, Xavier; Filbee-Dexter, Karen; Wernberg, Thomas (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-22)
      Environmental stressors related to climate change and other anthropogenic activities are impacting Arctic marine ecosystems at exceptional rates. Within this context, predicting future scenarios of deep-sea ecosystems and their consequences linked with the fate of coastal areas is a growing need and challenge. We used an existing food-web model developed to represent the outer basin of the Malangen ...
    • Fysiologiske responser på handtering hos flekksteinbit(Anarhichas minor Olafsen) 

      Iversen, Maren Marie Thode (Master thesis; Mastergradsoppgave, 2007-11)
      Stress og fysiologiske responser på stress kan være et stort problem i oppdrett av fisk. Dette har blitt forsket mye på hos laksefisk. Flekksteinbit (Anarhichas minor Olafsen), er en lovende oppdrettsart. I motsetning til laksefisk synes flekksteinbit i fangenskap å være svært fortrolig med folk og handtering. Fysiologiske responser på ulike stressorer har tidligere ikke vært undersøkt hos ...

      Ras GTPase-activating protein-binding proteins 1 and 2 (G3BP1 and G3BP2, respectively) are widely recognized as core components of stress granules (SGs). We report that G3BPs reside at the cytoplasmic surface of lysosomes. They act in a non-redundant manner to anchor the tuberous sclerosis complex (TSC) protein complex to lysosomes and suppress activation of the metabolic master regulator mechanistic ...
    • Gaining advantage by winning contests 

      Clark, Derek John; Nilssen, Tore; Sand, Jan Yngve (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-20)
      We consider a principal who faces many identical competitors, and who can distribute a prize fund over two consecutive contests. The winner of contest one gains an advantage in contest two where his effort is more productive than all rivals. We identify a tipping point for the productivity parameter, below which it is optimal for an effort-maximizing principal to place the whole prize in the second ...

      Ihlebæk, Hanne Marie (Master thesis; Mastergradsoppgave, 2010-05)
      Gammaherpesvirus causes the disease, malignant catarrhal fever (MCF), in wild and domestic ruminants worldwide. In Norway MCF occurs sporadically in wild and domestic ruminants. The present study examined the extent that semi-domesticated reindeer (Rangifer tarandus tarandus) in Finnmark, Norway, are exposed to gammaherpesvirus. A serological screening was performed to determine the prevalence of ...
    • Gastrointestinal nematodes in Icelandic reindeer (Rangifer tarandus tarandus) 

      Dembereldagva, Selengemurun (Master thesis; Mastergradsoppgave, 2021-01-18)
      Reindeer (<i>Rangifer tarandus</i>) are host to gastrointestinal-tract nematodes (GINs) throughout the world. Some populations of reindeer exist in almost complete isolation from others, and this can have a key influence on the species and infection rates of GINs. An example of an isolated reindeer population occurs in Iceland. In this study, I have investigated the prevalence of GINs in Icelandic ...
    • GATA-3 in Atlantic salmon (Salmo salar): Tissue distribution and its regulation of IL-4/13a promoter 

      Chi, Heng; Meng, Xianghu; Dalmo, Roy Ambli (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-14)
      GATA3 is a transcription factor that plays an important role in T cell lineage differentiation and T-helper 2 (Th2) type immune responses. In this study, we developed two rat antibodies against Atlantic salmon GATA-3 (anti-rSsGATA-3a and anti-rSsGATA-3b, respectively). The western blotting and immunofluorescence results showed that anti-rSsGATA-3b antibodies recognized endogenous SsGATA-3 proteins, ...
