(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)We tested the hypothesis that the coronate jellyfish Periphylla periphylla distributes vertically according to a preferential range of absolute light intensities. The study was carried out in Lurefjorden, Norway, a fjord ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The discovery of Ice Ages is one of the most revolutionary advances made in the Earth sciences. In 1824 Danish‐Norwegian geoscientist Jens Esmark published a paper stating that there was indisputable evidence that Norway ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)In 2010 we rediscovered the complete set of meteorological observation protocols made by Jens Esmark (1762–1839) during his years of residence in the Norwegian capital of Oslo (then Christiania). From 1 January 1816 to 25 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract As the excitation–contraction coupling is inseparable during voluntary exercise, the relative contribution of the mechanical and neural input on hypertrophy-related molecular signalling is still poorly understood. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Aquatic plant nutrient concentrations provide important information to characterise their role in nutrient retention and turnover in aquatic ecosystems. While large standing biomass of aquatic plants is typically found in ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)In animals with long generation times, evolution of physiological and morphological traits may not be fast enough to keep up with rapid climate warming, but thermoregulatory behaviour can possibly serve as an important ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Mechanisms have evolved that allow cells to detect signals and generate an appropriate response. The accuracy of these responses relies on the ability of cells to discriminate between signal and noise. How cells filter ...

Knockout of NTHL1 DNA Glycosylase affects the Mitochondrial Transcriptome, DNA copy number and shows Tolerance to Parkinsonism-Inducing Drugs in Human CellsRestricted Access (Master thesis / Masteroppgave, 2023)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)There is accumulating evidence that interfering with the basic aging mechanisms can enhance healthy longevity. The interventional/therapeutic strategies targeting multiple aging hallmarks could be more effective than ...
-
(Master thesis / Masteroppgave, 2022)Hensikten med dette prosjektet var å utvikle en automatisert metode for å finne parasitter i hoppekreps. Jeg lette mer spesifikt etter Blastodinium som er en slekt av parasittiske dinoflagellater. Derfor ble det brukt ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Ablation of glycosylated lysosomal membrane protein (GLMP, formerly known as NCU-G1) has been shown to cause chronic liver injury which progresses into liver fibrosis in mice. Both lysosomal dysfunction and chronic liver ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Climate and land-use changes are leading to impacts on individual ecosystems as well as shifts in transfer dynamics between interconnected systems. At the land-ocean interface, changes in riverine inputs of organic matter ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Agricultural, forestry‐impacted and natural catchments are all vectors of nutrient loading in the Nordic countries. Here, we present concentrations and fluxes of total nitrogen (totN) and phosphorus (totP) from 69 Nordic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Global change affects gross primary production (GPP) in benthic and pelagic habitats of northern lakes by influencing catchment characteristics and lake water biogeochemistry. However, how changes in key environmental ...
-
(Doctoral thesis / Doktoravhandling, 2013)Many African wildlife species are at risk of extinction as a result of habitat loss and fragmentation associated with human influence. Among these is the endangered antelope, mountain nyala (Tragelaphus buxtoni), endemic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Among vertebrates, amphibians currently have the highest proportion of threatened species worldwide, mainly through loss of habitat, leading to increased population isolation. Smaller amphibian populations may lose more ...
-
(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 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Although the phenomenon of skipped spawning has been described in numerous fishes, time-series are scarce. We used the presence of post-ovulatory follicles in histological gonad slides from females not developing oocytes ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)Many species around the world have collapsed, yet only some have recovered. A key question is what happens to populations post collapse. Traditionally, marine fish collapses are linked to overfishing, poor climate, and ...
