JASPAR 2010: the greatly expanded open-access database of transcription factor binding profiles
(Peer reviewed; Journal article, 2010)JASPAR (http://jaspar.genereg.net) is the leading open-access database of matrix profiles describing the DNA-binding patterns of transcription factors (TFs) and other proteins interacting with DNA in a sequence-specific ... -
Jellyfish distribute vertically according to irradiance
(Peer reviewed; Journal article, 2017-03)We tested the hypothesis that the coronate jellyfish Periphylla periphylla distributes vertically according to a preferential range of absolute light intensities. The study was carried out in Lurefjorden, Norway, a fjord ... -
Judging a salmon by its spots: Environmental variation is the primary determinant of spot patterns in Salmo salar
(Peer reviewed; Journal article, 2018-04-12)Background. In fish, morphological colour changes occur from variations in pigment concentrations and in the morphology, density, and distribution of chromatophores in the skin. However, the underlying mechanisms remain ... -
July mean temperature and annual precipitation trends during the Holocene in the Fennoscandian tree-line area: pollen-based climate reconstructions
(Peer reviewed; Journal article, 2001)July mean temperature and annual precipipation during the last 9900 cal. yr BP were recon structed from pollen assemblages preserved in a sediment core from northern Finland. Quantitative recon structions were performed ... -
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 ... -

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 ... -
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-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 ... -
Learning through practice in biology education
(Doctoral thesis, 2019-04-25)Work continues to be an important educational measure in higher education. It has received increasing focus both among policymakers, educators, and in educational science research as a valuable addition to campus-based, ... -
Length Related Diurnal Vertical Migration of Cod (Gadus morhua L.), Haddock (Melanogrammus aeglefinus L.) and Redfish (Sebastes spp.) in the Barents Sea
(Master thesis, 2001)Vertical fish migrations can increase variability in bottom survey data, especially if unknown diurnal length-frequency distribution is different between layers. Surveys, using echo sounder technique to estimate demersal ... -
Life after fire: smoke and ash as germination cues in ericads, herbs and graminoids of northern heathlands
(Peer reviewed; Journal article, 2014-05-02)Question: What is the impact of the fire cues smoke and ash on seed germination of important functional groups in the heathland system, namely ericads, herbs and graminoids? We predict that if germination from heathland ... -
Life after fire: the impact of fire on species composition and diversity in coastal heathlands
(Doctoral thesis, 2015-09-11)Fire prone coastal heathlands are widespread, and range from naturally fire prone Mediterranean-type heathlands, to the anthropogenic heathlands of north-west Europe. Regardless of its source, fire is an important disturbance ... -
Life histories determine divergent population trends for fishes under climate warming
(Journal article; Peer reviewed, 2020-08-14)Most marine fish species express life-history changes across temperature gradients, such as faster growth, earlier maturation, and higher mortality at higher temperature. However, such climate-driven effects on life histories ... -
