The influence of food access on spermatophore production in the pelagic copepod, Temora longicornis (Master thesis / Masteroppgave, 2013)In studies on reproductive ecology of pelagic copepods, the role of males is often neglected and male reproductive investment is not well understood. Lately there has been an increasing interest in the topic and it has ...
-
(Master thesis / Masteroppgave, 2013)The present study is part of an ongoing effort to monitor the pollution situation in the inner Oslofjord. The purpose of the study was to investigate effects of pollutants on the resident cod population in the area. The ...
-
(Master thesis / Masteroppgave, 2013)Speciation involves the evolution of reproductive barriers that maintain the genetic integrity of species. Premating barriers, in particular, have been referred to as one of the most important mechanisms in keeping species ...
-
(Master thesis / Masteroppgave, 2013)Iron oxide nanoparticles are widely used for magnetic resonance imaging, and there is a rapidly expanding research interest in using these nanoparticles for drug delivery or cell labeling. Therefore we need a better ...
-
(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, 2013)Partial migration is common among northern ungulates, typically involving an altitudinal movement for seasonally migratory individuals. The main driving force behind migration is the benefit of an extended period of access ...
-
(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 ...
-
(Master thesis / Masteroppgave, 2013)Sorghum is ranked the fifth most produced food crop in the world, and is a dietary staple for over 500 million people in over 30 countries. It is the second most produced food crop in Africa, where cultivation of local ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)Next generation sequencing of ribosomal DNA is increasingly used to assess the diversity and structure of microbial communities. Here we test the ability of 454 pyrosequencing to detect the number of species present, and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)Background Plague (Yersinia pestis infection) is a vector-borne disease which caused millions of human deaths in the Middle Ages. The hosts of plague are mostly rodents, and the disease is spread by the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)Harvest control rules (HCRs) have been implemented for many fisheries worldwide. However, in most instances, those HCRs are not based on the explicit feedbacks between stock properties and economic considerations. This ...
-
(Master thesis / Masteroppgave, 2013)The dry rot fungus Serpula lacrymans is known as one of the most aggressive fungal house invaders in temperate regions. Recent genetic and phylogeographic studies have shed light on the distribution, colonisation and ...

Differential effects of bone morphogenetic proteins (BMPs) in human memory B cellsRestricted Access (Master thesis / Masteroppgave, 2013)
-
(Master thesis / Masteroppgave, 2013)Prostate cancer (PCa) is the most common type of cancer among men in Western countries. An approach to better PCa diagnosis, prognosis and management is to identify genes that are prostate-specific and differentially ...

Aberrant m6A regulation in Alkbh5 deficient mice results in increased DNA methylation and altered gene expressionRestricted Access (Master thesis / Masteroppgave, 2013)
-
(Master thesis / Masteroppgave, 2013)The Casitas B-lineage lymphoma (Cbl) family of ubiquitin ligases has been studied for years regarding their important role in downregulation of ligand bound epidermal growth factor receptor (EGFR). The two isoforms c-Cbl ...
-
(Master thesis / Masteroppgave, 2013)Steroide hormone receptors (SHRs) are ligand-modulated transcription factors that regulate important physiological processes. The effects of SHRs are regulated by their coordinated interaction with other transcription ...
-
(Master thesis / Masteroppgave, 2013)Introduction: Lake productivity is determined by the amount of nutrients and light available. While phosphorus is the main limiting nutrient in freshwater systems light availability can be reduced by several factors, while ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)Understanding the drivers (internal and external) that determine the productivity of marine ecosystems is challenging. For example, the correct estimate of recruitment is essential to estimate fish stock abundance. In this ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)Prediction of year-class strength is a critical challenge for fisheries managers. Theoretically, predictions of recruitment should be better when they are based on estimates of cohort size taken close to the age of recruitment ...
