(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)The introduction of immigrants into resident populations may disturb the social organisation of the latter. It is often stated that males compete with males for access to mates, while females compete with females and/or ...

Diversity and community composition of root-associated fungi explored by high throughput sequencing (Doctoral thesis / Doktoravhandling, 2012)Interactions between plant roots and fungi are well known from most terrestrial ecosystems. Mycorrhizal association is the most prominent plant-fungi interaction, where the fungal partners increase the water and nutrient ...
-
(Doctoral thesis / Doktoravhandling, 2008)Cyanobakterier (=blågrønnalger) forekommer i nesten alle norske innsjøer, og masseoppblomstringer av dem har vist seg å være utbredt over hele verden. Et stort problem ved oppblomstringer av cyanobakterier er giftstoffene ...

(Doctoral thesis / Doktoravhandling, 2009)Pockmarks have now been recognised for nearly four decades, and are one of the most obvious and abundant structural features of the seafloor in some areas, yet there is still little knowledge of their influence on fauna ...
-
(Doctoral thesis / Doktoravhandling, 2008)This thesis investigates competition and ecological speciation by comparing habitat use, foraging ecology and physiology of two fish populations (Coregonus spp.) in a temperate lake. It demonstrates that dietary differences ...
-
(Doctoral thesis / Doktoravhandling, 2008)I dette arbeidet har vi utviklet molekylære metoder for simultant å måle forekomsten av ulike mikrober i komplekse samfunn. Koblet med økologisk analyse gir dette oss helt nye muligheter til å forstå hvordan bakteriesamfunn ...
-
(Doctoral thesis / Doktoravhandling, 2009)Denne avhandlingen viser at fisk utsatt for lave nivåer av produsertvann over lang tid kan utvikle skader på arvematerialet, modnes senere og få redusert vekst. Produsertvann er et biprodukt fra utvinningen av olje og ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)Alpine ecosystems are generally nitrogen (N) limited with low rates of N mineralization. Herbivory may affect N cycling and N losses and thus long-term productivity of ecosystems. Using a controlled grazing experiment ...
-
(Master thesis / Hovedoppgave, 2004)1. Sammendrag Toksikogenomikk forener metoder brukt i klassisk toksikologi og metoder fra molekylær biologi. Den nye disiplinen bruker transkripsjonal genprofilering som et ledd i risiko- vurdering for både nye og gamle ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)Background Cell lines from Atlantic salmon kidney have made it possible to culture and study infectious salmon anemia virus (ISAV), an aquatic orthomyxovirus affecting farmed Atlantic salmon. However, ...
-
(Doctoral thesis / Doktoravhandling, 2009)The main objective of these studies was to utilize the large amount of co-occurring fauna and chemical data collected in different contamination zones around offshore installations to derive ecologically relevant protection ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2008)Background Cyanobacteria produce a wealth of secondary metabolites, including the group of small cyclic heptapeptide hepatotoxins that constitutes the microcystin family. The enzyme complex that directs the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2010)Background DNA-dependent RNA polymerase IV and V (Pol IV and V) are multi-subunit enzymes occurring in plants. The origin of Pol V, specific to angiosperms, from Pol IV, which is present in all land plants, ...
-
(Doctoral thesis / Doktoravhandling, 2010)This thesis focuses on the natural history of the dry rot fungus Serpula lacrymans and closely related taxa within Serpulaceae. In the first study the phylogenetic relationships within Serpulaceae have been investigated ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)Background The fungal genus Serpula (Serpulaceae, Boletales) comprises several saprotrophic (brown rot) taxa, including the aggressive house-infecting dry rot fungus Serpula lacrymans. Recent phylogenetic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)Background The deer ked (Lipoptena cervi), a hematophagous ectoparasite of Cervids, is currently spreading in Scandinavia. In Norway, keds are now invading the south-eastern part of the country and the ...
