(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Throughout the oceans, small fish and other micronekton migrate between daytime depths of several hundred meters and near-surface waters at night. These diel vertical migrations of mesopelagic organisms structure pelagic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)We make a comparison of the mesopelagic sound scattering layers (SLs) in two contrasting optical environments; the clear Red Sea and in murkier coastal waters of Norway (Masfjorden). The depth distributions of the SL in ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The deep scattering layer (DSL) is a ubiquitous acoustic signature found across all oceans and arguably the dominant feature structuring the pelagic open ocean ecosystem. It is formed by mesopelagic fishes and pelagic ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Filamentous cyanobacteria have substantial niche overlap, and the causal mechanism behind their succession remains unclear. This has practical significance since several filamentous genera are the main producers of the ...

Linking geology and microbiology: Inactive pockmarks affect sediment microbial community structure (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Pockmarks are geological features that are found on the bottom of lakes and oceans all over the globe. Some are active, seeping oil or methane, while others are inactive. Active pockmarks are well studied since they harbor ...
-
(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, 2017)The gastrointestinal (GI) microbiome is a densely populated ecosystem where dynamics are determined by interactions between microbial community members, as well as host factors. The spatial organization of this system is ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)The grass parasitic fungus Claviceps purpurea sensu lato produces sclerotia with toxic indole alkaloids. It constitutes several genetic groups with divergent habitat preferences that recently were delimited into separate ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)One of the most dramatic episodes of sustained diversification of marine ecosystems in Earth history took place during the Early to Middle Ordovician Period. Changes in climate, oceanographic conditions, and trophic structure ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Late developmental stages of the marine copepods in the genus Calanus can spend extended periods in a dormant stage (diapause) that is preceded by the accumulation of large lipid stores. We assessed how lipid metabolism ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Lipids are essential components of exosomal membranes, and it is well-known that specific lipids are enriched in exosomes compared to their parent cells. In this review we discuss current knowledge about the lipid composition ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)Coralline red algae in the non-geniculate genera Clathromorphum, Phymatolithon and Lithothamnion are important benthic ecosystem engineers in the photic zone of the Arctic and Subarctic. In these regions, the systematics ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Liver sinusoidal endothelial cells (LSECs) are fenestrated endothelial cells with a unique, high endocytic clearance capacity for blood-borne waste macromolecules and colloids. This LSEC scavenger function has been ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Background Recent global changes have led to an increase in distribution of ticks towards higher elevation and latitude in Europe and livestock are at increasing risk of contracting tick-borne diseases, but psychological ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Small, isolated and/or peripheral populations are expected to harbour low levels of genetic variation and may therefore have reduced adaptability to environmental change, including climate warming. In the Arctic, global ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Vertebrate predation by invertebrates has been classically underexplored and thus underestimated, despite the fact that many arthropods consume vertebrates. To shed some light on the relevance that spider predation may ...

Localization of a putative RNA pyrophosphohydrolase in the unicellular green alga Chlamydomonas reinhardtiiRestricted Access (Master thesis / Masteroppgave, 2018)In bacteria an RNA pyrophosphohydrolase (RppH) has been shown to remove pyrophosphate (PPi) from the 5’ end of mRNAs thereby allowing binding of RNases that degrade the transcripts. In previous master projects a gene that ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Ecological and evolutionary effects of environmental variation on wild populations are of particular interest in a changing world. Large-scale environmental indices are classically used as environmental explanatory variables ...
