(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2008)Background Identification of DNA sequence diversity is a powerful means for assessing the species present in environmental samples. The most common molecular strategies for estimating taxonomic composition ...
-
(Master thesis / Masteroppgave, 2012)Breeding systems for species with cryptic lives are difficult to examine in nature based on purely observational studies. In this study, a genetic approach was used to investigate the breeding system of a population of a ...
-
(Master thesis / Masteroppgave, 2006)Within biomonitoring it has been common practice to analyse the concentration of pollutants in organisms. However, focus is shifting towards an approach which combines chemical analyses with measurements of effects in ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2002)Mucosal surfaces are protected by polymeric immunoglobulins that are transported across the epithelium by the polymeric immunoglobulin receptor (pIgR). Only polymeric IgA and IgM containing a small polypeptide called the ...

(Master thesis / Masteroppgave, 2006)Abstract Perfluorinated alkylated substances (PFAS) are persistent compounds with many uses, for example impregnation of fabrics and leather and as fire-retardants. Recently, it has focused on these compounds, because of ...
-
(Master thesis / Masteroppgave, 2006)Fluorinated compounds (PFAS) and tributyltin (TBT) are found in significant amounts in the seas around the world and it is therefore of interest to know whether, and how, they affect coastal ecosystems. Three sediment-dwelling ...
-
(Master thesis / Hovedoppgave, 2006)Bromerte flammehemmere (BFR) er persistente og hydrofobe kjemikalier som har vist seg å kunne akkumuleres i forskjellige organismer, inkludert mennesker og miljø. Det globale omfanget av disse forurensningene gir grunn til ...
-
(Master thesis / Masteroppgave, 2008)The nutritional stress hypothesis formulated by Nowicki et al. (1998) is based on the findings that brain structures underlying song learning in songbirds largely develop during the first few months post-hatching; a period ...
-
(Master thesis / Masteroppgave, 2009)In many species of birds, the quality of the nest site may have important fitness consequences. The focus of the present study was to see if nest box choice in blue tits (Cyanistes caeruleus) and great tits (Parus major) ...

Ciliate and phytoplankton species composition in the sea-surface microlayer in the outer Oslofjord (Master thesis / Masteroppgave, 2011)Abstract The sea-surface microlayer is the boundary layer between the water of the oceans and the atmosphere occupying approximately “1000 micrometer” uppermost part of the sea-surface microlayer (SML) (Liss and Duce, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2007)Climate influences a population through a variety of processes, including reproduction, growth, migration patterns and phenology. Climate may operate either directly through metabolic and reproductive processes or indirectly ...
-
(Master thesis / Masteroppgave, 2007)Climatic fluctuations characterized the climate in East Africa during the Plio-Pleistocene. These variable conditions established opportunities for ecological fragmentation with subsequent genetic isolation of species ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)Background:The implementation of high throughput sequencing for exploring biodiversity poses high demands on bioinformatics applications for automated data processing. Here we introduce CLOTU, an online and open access ...
