Studies of JAK/STAT signaling in Atlantic salmon
(Doctoral thesis; Doktorgradsavhandling, 2014-06-27)
In mammals the JAK-STAT pathway plays a significant role in mediating the biological activities of both type I and type II IFN, where JAKs are receptor associated kinases and STATs the transcription factors they activate. At the start of this project the knowledge of the JAK-STAT pathway in fish in general was scarce and there were few reports describing the function of any JAK-STAT family member ...
The invasive red king crab (Paralithodes camtschaticus): Mortality, individual growth and dispersal in Norwegian waters
(Doctoral thesis; Doktorgradsavhandling, 2014-10-01)
To improve local economy, the red king crab (Paralithodes camtschaticus) was introduced to the Barents Sea by Soviet scientists in the 1960s. Adapting well to the new environment, the growing population gradually invaded new areas along the coast of northern Norway. The red king crab has become a valuable marine resource but as an introduced species, it is also a potential threat to the ecosystem. ...
Regjerlig kyst? Kunnskap og politikk i kystsoneplanlegging
(Doctoral thesis; Doktorgradsavhandling, 2014-05-23)
Hvordan forvaltes kystsonen? Denne avhandlingen søker å gi svar på dette spørsmålet ved å følge en kommunal kystsoneplanprosess. Case-området er Alta kommune. Avhandlingen studerer hvilke praksiser de kommunale planmyndighetene har satt i gang for å utarbeide en arealplan for sjøområdet. Hvordan har kommunen organisert planprosessen? Hvordan foretar planmyndighetene avveininger mellom ulike interesser? ...
Diversity of marine wood-inhabiting fungi in North Norway
(Doctoral thesis; Doktorgradsavhandling, 2014-05-27)
Marine fungi in arctic waters have rarely been studied. The main aim of this thesis was to explore the diversity of driftwood inhabiting fungal communities in the cold waters of North Norway. In order to gain as comprehensive view as possible, different methodological approaches were applied on the same study substrates, and the recovered fungal communities were analysed for taxonomic, phylogenetic ...
Effects of latitudinal climate conditions on quality attributes in Brassica oleracea
(Doctoral thesis; Doktorgradsavhandling, 2014-02-17)
Brassica is a genus of plants that includes vegetables that are widely used for human consumption and contain high levels of health-promoting compounds.
These vegetables are grown in large parts of the world, and the environmental conditions where they are cultivated can affect several quality
attributes. The research presented in this thesis examined how variation in growth conditions with ...
Isolation and Characterisation of Bioactive Secondary Metabolites from Arctic, Marine Organisms
(Doctoral thesis; Doktorgradsavhandling, 2014-12-09)
The list of achievements in developing pharmaceuticals and other useful products originating from Nature is long, and it continues to extend. Marine bioprospecting alone has generated three novel drugs in the last four years. The continued success motivates further bioprospecting efforts in the search for utilisable products from natural sources.
In this thesis, extracts of Arctic marine organisms ...
Induction of Atlantic salmon type I interferon and antagonism by infectious pancreatic necrosis virus
(Doctoral thesis; Doktorgradsavhandling, 2014-04-08)
Viral infections are a leading cause of mortality in the farming of Atlantic salmon in Norway. Viral outbreaks cause heavy losses each year, and one of the most predominant viral diseases is infectious pancreatic necrosis (IPN). The virus causing this disease, the infectious pancreatic necrosis virus (IPNV), belongs to the Birnaviridae family of viruses with a double-stranded RNA (dsRNA) genome. ...
Health benefits of seafood consumption - with special focus on household preparations and bioactivity in animal models
(Doctoral thesis; Doktorgradsavhandling, 2014-06-24)
Fish consumption is well acknowledged to reduce risk of cardiovascular disease, the health benefits mainly being associated with EPA and DHA. Increasing evidence, however, demonstrate that also the proteins and other bioactive compounds may be of relevance to human health. This project was initiated in order to examine the nutritional composition and bioactivity related to cardiovascular disease ...
Foraging, reproduction and survival of the zooplanktivorous seabird Little Auk (Alle alle) in the Arctic in relation to climatic and environmental variability
(Doctoral thesis; Doktorgradsavhandling, 2014-06-23)
The ability of individuals to acquire and store energy for life-history traits such as reproduction
and survival, is finite. This demands prioritizing some traits at the expense of other traits. Which
traits to prioritize, depends on the life-history strategy of a species. ‘Slow’-living species, in
contrast to ‘fast’-living species, mature late, produce small broods, have low extrinsic mortality
and ...
Analysis of processes at the haustorial interfaces between Cuscuta reflexa and its hosts
(Doctoral thesis; Doktorgradsavhandling, 2014-08-27)
The genus Cuscuta comprises a group of holoparasitic dicotyledonous angiosperms that cause damage to many economically important crops. Parasitic plants form physical and physiological connections (haustoria) with the parenchyma and vascular vessels of compatible host plants. These connections provide them with water, mineral nutrients and organic compounds. Over time, this life style has led to ...
