(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)The human methyltransferases (MTases) METTL21A and VCP-KMT (METTL21D) were recently shown to methylate single lysine residues in Hsp70 proteins and in VCP, respectively. The yet uncharacterized MTase encoded by the YNL024C ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)The aim of this study was to describe the frequency and distribution of Saffold virus in longitudinal stool samples from children, and test for association with development of persistent autoantibodies predictive of type ...
-
(Master thesis / Masteroppgave, 2014)Phenotypic plasticity allows organisms with identical genotypes to develop different phenotypes in response to different environmental cues. Phenotypic plasticity is a trait in itself, and can be either adaptive or ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)With the surge of GPS-technology, many studies uncovered space use of mobile animals and shed light on the underlying behavioral mechanisms of habitat selection. Habitat selection and variation in either occurrence or ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Biological diversity is, to a large extent, a matter of variation in size. Proportional (isometric) scaling, where large and small individuals are magnified versions of each other, is often assumed to be the most common ...
-
(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, 2015)The littoral Collembola Cryptopygus clavatus spends the summer submerged, grazing on algae under water, and the winter on dry land. The cuticles of Collembola are, in general, highly water repellent, often superhydrophobic; ...

(Master thesis / Masteroppgave, 2019)The seasonal cycle of phytoplankton with emphasis on Pseudo-nitzschia was studied at Elle, Drøbak from September 2016 to August 2017. Vertical (1 m) and horizontal net hauls (20 – 0 m), and water samples (1 m) were collected ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Microalgae in the division Haptophyta play key roles in the marine ecosystem and in global biogeochemical processes. Despite their ecological importance, knowledge on seasonal dynamics, community composition and abundance ...

(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 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Viruses influence the ecology and diversity of phytoplankton in the ocean. Most studies of phytoplankton host–virus interactions have focused on bloom-forming species like Emiliania huxleyi or Phaeocystis spp. The role of ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Sex hormones, reproductive status, and pathogen load all affect stress. Together with stress, these factors can modulate the immune system and affect disease incidence. Thus, it is important to concurrently measure these ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Lake Gjerstadvann is a dimictic, oligotrophic, slightly acidified boreal lake in southern Norway (northwest Europe). The planktonic rotifer community of this lake was studied quantitatively during one year in order to ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)Seston is suspended particulate organic matter, comprising a mixture of autotrophic, heterotrophic and detrital material. Despite variable proportions of these components, marine seston often exhibits relatively small ...
-
(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, 2016)Intimin is an essential adhesin of attaching and effacing organisms such as entropathogenic Escherichia coli. It is also the prototype of type Ve secretion or inverse autotransport, where the extracellular C-terminal region ...
