(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)1. An increasing number of empirical studies aim to quantify individual variation in demographic parameters because these patterns are key for evolutionary and ecological processes. Advanced approaches to estimate individual ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Copepods are a critical component of ocean ecosystems, providing an important link between phytoplankton and higher trophic levels as well as regulating biogeochemical cycles of carbon (C) and nutrients. Lipid-rich animals ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Although artificial-selection experiments seem well suited to testing our ability to predict evolution, the correspondence between predicted and observed responses is often ambiguous due to the lack of uncertainty estimates. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)1. Quantifying the diet composition of apex marine predators such as killer whales (Orcinus orca) is critical to assessing their food web impacts. Yet, with few exceptions, the feeding ecology of these apex predators remains ...
-
(Master thesis / Masteroppgave, 2014)Aberrant DNA methylation is one of the most common alterations in cancer, and a vast diversity of methods for its investigation exists. Quantitative methylation-specific PCR (qMSP) is frequently used to estimate the amounts ...
-
(Master thesis / Masteroppgave, 2022)In the present study, the temporal and spatial paleoecology of the Lower Silurian Rytteråker Formation in the Oslo region, is explored through multivariate gradient analysis of a novel dataset of stratigraphically collected ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)An accurate method to estimate the age of a stain or the time since deposition (TsD) would represent an important tool in police investigations for evaluating the true relevance of a stain. In this study, two laboratories ...
-
(Doctoral thesis / Doktoravhandling, 2018)In this thesis, a general phosphoproteomics workflow was established by careful evaluation of the different steps for phosphopeptide enrichment. In addition, the application of two different collision energies for MS2 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Resource quantity and quality are fundamental bottom-up constraints on consumers. Best understood in autotroph-based systems, co-occurrence of these constraints may be common but remains poorly studied in detrital-based ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Populations of large mammals have declined at alarming rates, especially in areas with intensified land use where species can only persist in small habitat fragments. To support conservation planning, we developed habitat ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)The intracellular movement and positioning of organelles and vesicles is mediated by the cytoskeleton and molecular motors. Small GTPases like Rab and Arf proteins are main regulators of intracellular transport by connecting ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Rab proteins compose the largest family of small GTPases and control the different steps of intracellular membrane traffic. More recently, they have been shown to also regulate cell signaling, division, survival, and ...
-
Rab18 regulates focal adhesion dynamics by interacting with kinectin-1 at the endoplasmic reticulum (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The members of the Rab family of small GTPases are molecular switches that regulate distinct steps in different membrane traffic pathways. In addition to this canonical function, Rabs can play a role in other processes, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Rab proteins are well known regulators of intracellular trafficking; however, more and more studies point to their function also in other cellular processes, including cell migration. In this work, we have performed an ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Rab proteins are master regulators of intracellular membrane trafficking, but they also contribute to cell division, signaling, polarization, and migration. The majority of the works describing the mechanisms used by Rab ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Rab7a, a small GTPase of the Rab family, is localized to late endosomes and controls late endocytic trafficking. The discovery of several Rab7a interacting proteins revealed that Rab7a function is closely connected to ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Autophagy (macroautophagy) is a highly conserved eukaryotic degradation pathway in which cytosolic components and organelles are sequestered by specialized autophagic membranes and degraded through the lysosomal system. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Lysosomal signaling facilitates the migration of immune cells by releasing calcium to activate the actin-based motor myosin II at the cell rear. However, how the actomyosin cytoskeleton physically associates to lysosomes ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)To determine the present-day community composition of siliceous Rhizaria (Radiolaria and Phaeodaria) in Norwegian fjords, plankton tows were conducted in south-western and northern Norwegian fjords in September 2016. The ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Speciation encompasses a continuum over time from freely interbreeding populations to reproductively isolated species. Along this process, ecotypes – the result of local adaptation – may be on the road to new species. We ...
