      We present the results of an inventory and status assessment of alien species in Norway. The inventory covered all known multicellular neobiota, 2496 in total, 1039 of which were classified as naturalised. The latter constitute c. 3% of all species known to be stably reproducing in Norway. These figures are higher than expected from Norway’s latitude, which may be due a combination of ...
    • Decomposition in differing snow regimes in high Arctic Svalbard 

      Heavyside, Paige Kathryn (Master thesis; Mastergradsoppgave, 2019-05-29)
      Rapidly rising temperatures are having great effects on the high arctic ecosystem, historically characterized by long, cold winter periods, and cold dry summers. Due to the length of the winter season, arctic soils have been an important carbon sink, but may now be facing increased microbial activity due to increasing temperatures. Temperature, moisture, and litter quality play important roles in ...

    • In Silico Screening for inhibitors against Apicoplast Phosphate Translocator from Toxoplama gondii 

      Shamsuzzaman, Muhammad (Master thesis; Mastergradsoppgave, 2019-05-16)
      Apicomplexa parasites, including Toxoplasma gondii and Plasmodium falciparum, contain a secondary endosymbiosis-derived plastid like organ, called apicoplast, which is an anabolic hub. This apicoplast is fueled by phosphate translocator (APT), which transport phosphorylated sugar molecules in exchange of inorganic phosphate. Disruption of APT in T. gondii was found to be lethal for parasite. Beside ...

    • Brain capillarization in diving mammals: a selection of staining and quantification methods 

      Ciccone, Chiara (Master thesis; Mastergradsoppgave, 2019-05-15)
      Diving species can cope with acute and repeated hypoxia through adaptations that are absent in non-diving animals. One of the greatest challenges to deal with during diving is the lowering of the arterial oxygen pressure (PaO2), which causes a decrease in the driving force for the oxygen diffusion from the capillaries to the cells. My hypothesis is that the marine mammalian brain shows improved brain ...
    • Riverine and glacier influence on infaunal benthic communities in Isfjorden, Svalbard. 

      Ugelstad, Charlotte Pedersen (Master thesis; Mastergradsoppgave, 2019-05-15)
      Fjords are the interface between land and ocean, and processes happening on land have implication for the coastal areas. In addition, differences in fjord characteristics, such as morphology, sedimentation and water circulation, can drive differences in fjord ecology, including benthic community composition (Syvitsky et al. 1986). Soft-bottom macro-fauna was collected in August 2018 using a Van-Veen ...
    • Seasonality in mercury bioaccumulation in particulate organic matter and zooplankton in a river-influenced Arctic fjord (Adventfjord, Svalbard). 

      Carrasco, Nathalie (Master thesis; Mastergradsoppgave, 2019-05-15)
      Methylmercury (MeHg) is of concern because it has the capacity to readily bioaccumulate and biomagnify along trophic levels until humans, exhibiting toxic effects such as neurotoxicity. Increased permafrost melt (that stores large amounts of carbon and mercury (Hg)) and river inputs, are expected to increase the exposure to Hg through uptake and transfer of contaminants through the food web. The ...

      Klemetsen, Terje; Willassen, Nils Peder; Karlsen, Christian René (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-04)
      Understanding fish‐microbial relationships may be of great value for fish producers as fish growth, development and welfare are influenced by the microbial community associated with the rearing systems and fish surfaces. Accurate methods to generate and analyze these microbial communities would be an important tool to help improve understanding of microbial effects in the industry. In this study, ...
    • Activity of XTHs during host plant infection by the parasitic plant Cuscuta. 

      Sarfowaa, Adwoa (Master thesis; Mastergradsoppgave, 2019-05-15)
      Parasitic plants including Cuscuta develop specialized structures called haustoria during infection. These specialized organs give the parasite the capacity of host attachment, invasion, vasculature connection and material transfer between the host and the parasite. Successful invasion allows organic substances, nutrients and water to flow into the parasite through the host phloem and xylem cells. ...
