(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Strictly speaking, fundamental niches are inestimable. Nevertheless, ecologists attempt approximating them to understand species ’ distribution and plasticity to environmental changes, with invaluable repercussions on both ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Gillnet sampling and analyses of otolith shape, vertebral count and growth indicated the presence of three putative Atlantic herring (Clupea harengus L.) populations mixing together over the spawning season February–June ...
-
(Master thesis / Masteroppgave, 2013)This thesis examines the phytoplankton diversity in the Oslo Fjord and the seasonality of the size, shape and abundance of the genus Dinophysis Ehrenberg. The genus, which contains several toxin-producing species, has ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Large interannual fluctuations in the numbers of offspring joining a teleost population are common, yet factors affecting offspring production, a key driver of fish population size and demography, are often poorly understood. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Salinity is one of the key factors that affects metabolism, survival and distribution of fish species, as all fish osmoregulate and euryhaline fish maintain osmotic differences between their extracellular fluid and either ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Gelatinous organisms apparently play a central role in deep pelagic ecosystems, but lack of observational methodologies has restricted information on their behaviour. We made acoustic records of diel migrating jellyfish ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Background: Signalling proteins often contain several well defined and conserved protein domains. Structural analyses of such domains by nuclear magnetic spectroscopy or X-ray crystallography may greatly inform the function ...
-
(Master thesis / Masteroppgave, 2018)Road and tunnel wash runoff contain a mixture of organic and inorganic contaminants that threatens the quality of natural water bodies, and the health of the organisms dependent on these waters. A variety of treatment ...
-
(Doctoral thesis / Doktoravhandling, 2013)Mennesker har i lang tid forvaltet hjortevilt for ulike formål som mat, troféer eller bestandsregulering. Forvaltningen foregår gjennom ulike former for selektiv jakt. Pga. alders- og kjønnsspesifikke kvoter og jegernes ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)The Gauss-peak spectra (GPS) method represents individual pigment spectra as weighted sums of Gaussian functions, and uses these to model absorbance spectra of phytoplankton pigment mixtures. We here present several ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)The six transmembrane protein of prostate 2 (STAMP2) is an androgen‐regulated gene whose mRNA expression is increased in prostate cancer (PCa). Here, we show that STAMP2 protein expression is increased in human PCa compared ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)A persistent debate in population ecology concerns the relative importance of environmental stochasticity and density dependence in determining variability in adult year-class strength, which contributes to future reproduction ...
-
(Master thesis / Masteroppgave, 2015)Ferredoxins are iron-sulfur proteins that transfer electrons in different cellular processes. In Bacillus cereus there are two genes for ferredoxins that have been identified, one present with a [2Fe-2S] cluster (BC2795) ...

Structure-function relationship of Shiga toxins; Role of the A-subunit in complex stability and endocytosisRestricted Access (Master thesis / Masteroppgave, 2014)
-
(Master thesis / Masteroppgave, 2015)
-
(Master thesis / Masteroppgave, 2015)My experiments tried to investigate the effect of available surfaces on rotifer growth, and the benefits of the attached state. A linear model was formulated to test whether the predictions for functional respones of ...
