Kanamycin resistens i det naturlige miljø i Sør-vest Norge; naturlig forekomst av aminoglykosid fosfotransferase (3) benyttet som markører i genmodifiserte organismer (GMO)
(Master thesis, 2014-04-11)Sammendrag Genmodifiserte organismer er vidt utbredt blant verdens ledende matprodusenter. Bruk av markørgener som koder for antibiotikaresistens er vidt utbredt, særlig bruk av aph(3)-II /(npt-II). Det er bred enighet om ... -
Kartlegging av patogendynamikken hos oppdrettslaks (salmo salar L.) med diagnosen pankreassykom (PD)
(Master thesis, 2011-11)Pankreassykdom (PD) er en vanlig og alvorlig sykdom på oppdrettsfisk, atlantisk laks (Salmo salar L.) og regnbueørret (Oncorhynchus mykiss) på Vestlandet. Den antatte årsaken til sykdommen er ... -
Kloning, karakterisering og ligandaktivering av aryl hydrokarbonreseptor 2 (AHR2) fra Atlanterhavstorsk (Gadus morhua)
(Master thesis, 2016-03-31)Aryl hydrokarbonreseptor (AHR) er en ligandaktivert transkripsjonsfaktor som regulerer en rekke fase I- og fase II biotransformasjonsenzymer. AHR tilhører en familie av transkripsjonsfaktorer som inneholder et basisk heliks ... -
Knowledge co-production in the Helge å catchment: a comparative analysis
(Journal article; Peer reviewed, 2022)Addressing sustainability challenges in landscape management requires processes for co-producing usable knowledge together with those who will use that knowledge. Participatory futures methods are powerful tools for attaining ... -

Lack of population genetic structure of lumpfish along the Norwegian coast: A reappraisal based on EST-STRs analyses
(Journal article; Peer reviewed, 2022)Lumpfish is now the single most important cleaner fish species to date and there is an extensive lumpfish translocation along the Norwegian coast. A reliable baseline information about the population genetic structure of ... -
Lake-sediment evidence for local and remote sources of atmospherically deposited pollutants on Svalbard
(Peer reviewed; Journal article, 2004)Twenty-one lakes along the west coast of Svalbard were cored between 28 July and 14 August 1995. Five cores were 210Pb dated and analysed for spheroidal carbonaceous particles (SCPs), indicators of deposition from fossil-fuel ... -
Lake-sediment records of recent environmental change on Svalbard: results of diatom analysis
(Peer reviewed; Journal article, 2004)Surface sediments from 23 lakes on Svalbard were analysed for diatoms. 182 taxa were found but samples generally have a low richness, with the majority of sites dominated by benthic genera such as Fragilaria, Navicula, and ... -
Land use change and coastal water darkening drive synchronous dynamics in phytoplankton and fish phenology on centennial timescales
(Journal article; Peer reviewed, 2024)At high latitudes, the suitable window for timing reproductive events is particularly narrow, promoting tight synchrony between trophic levels. Climate change may disrupt this synchrony due to diverging responses to ... -
Land-use and climate impacts on drought resistance and resilience in coastal heathland ecosystems
(Doctoral thesis, 2021-12-15)Background: Coastal heathlands of north-western Europe are semi-natural landscapes of high conservation value. These are ancient and historically widespread landscapes, but anthropogenic land-use and climate change are now ... -
Large annual variation in the amount of skipped spawning for female Northeast Arctic haddock Melanogrammus aeglefinus
(Journal article; Peer reviewed, 2020-10)Although the phenomenon of skipped spawning has been described in numerous fishes, time-series are scarce. We used the presence of post-ovulatory follicles in histological gonad slides from females not developing oocytes ... -
Large mesopelagic fishes biomass and trophic efficiency in the open ocean
(Peer reviewed; Journal article, 2014-02-07)With a current estimate of ~1,000 million tons, mesopelagic fishes likely dominate the world total fishes biomass. However, recent acoustic observations show that mesopelagic fishes biomass could be significantly larger ... -
Last Glacial Maximum environmental conditions at Andøya, northern Norway; evidence for a northern ice-edge ecological “hotspot”
(Journal article; Peer reviewed, 2020)Andøya on the NW coast of Norway is a key site for understanding the Last Glacial Maximum (LGM) in northern Europe. Controversy has arisen concerning the local conditions, especially about the timing and extent of local ... -
Last-century vegetational changes in northern Europe. Characterisation, causes, and consequences
(Doctoral thesis, 2011-11-04)In the face of recent changes in environmental conditions and climate, longterm studies provide important insights into patterns and processes of vegetational change. In northern Europe, however, long-term studies are rare ... -
Late Quaternary chironomid community structure shaped by rate and magnitude of climate change
(Journal article; Peer reviewed, 2021)Much is known about how climate change impacts ecosystem richness and turnover, but we have less understanding of its influence on ecosystem structures. Here, we use ecological metrics (beta diversity, compositional disorder ... -
