(Master thesis / Masteroppgave, 2020)As an effect of climate change and alterations in land use, the ranges of roe deer and also that of their ectoparasites, like the sheep tick (Ixodes ricinus) are expanding. This has also increased the occurrence of tick-borne ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Wild fish aggregate at aquaculture net-pens, but the underlying mechanisms are not fully understood. This study examined how salmon farms attract coastal Atlantic cod Gadus morhua from their inshore spawning grounds. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The ocean is a lifeline for human existence, but current practices risk severely undermining ocean sustainability. Present and future social−ecological challenges necessitate the maintenance and development of knowledge ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Australian funnel-web spiders are infamous for causing human fatalities, which are induced by venom peptides known as δ-hexatoxins (δ-HXTXs). Humans and other primates did not feature in the prey or predator spectrum during ...

B cell receptor ligation induces display of V-region peptides on MHC class II molecules to T cells (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The B cell receptors (BCRs) for antigen express variable (V) regions that are enormously diverse, thus serving as markers on individual B cells. V region-derived idiotypic (Id) peptides can be displayed as pId:MHCII complexes ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)As in humans, young, female, spontaneously hypertensive rats (SHR) have a lower blood pressure than male SHR. In male, normotensive rats (WKY), α2- and β1+2-adrenoceptors (AR) reciprocally controlled catecholamine release ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Formation of bacterial biofilms is a risk with many in situ medical devices. Biofilm-forming Bacillus species are associated with potentially life-threatening catheter-related blood stream infections in immunocompromised ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Cyclic diguanylate (c-di-GMP) signalling affects several cellular processes in Bacillus cereus group bacteria including biofilm formation and motility, and CdgF was previously identified as a diguanylate cyclase promoting ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Context The Complementary Habitat Hypothesis posits that animals access resources for different needs by moving between complementary habitats that can be seen as ‘resource composites’. These movements can occur over a ...
-
(Master thesis / Masteroppgave, 2017)Water is a unique substance and a vital part of life. Today, freshwater ecosystems are considered as one of the most vulnerable ecosystems on Earth. Degradation of lakes and rivers caused by water pollution, climate change, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Many bacteria, both environmental and pathogenic, exhibit the property of autoaggregation. In autoaggregation (sometimes also called autoagglutination or flocculation), bacteria of the same type form multicellular clumps ...
-
Bacterial bioindicators enable biological status classification along the continental Danube river (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract Despite the importance of bacteria in aquatic ecosystems and their predictable diversity patterns across space and time, biomonitoring tools for status assessment relying on these organisms are widely lacking. ...
-
(Doctoral thesis / Doktoravhandling, 2019)Friend or foe? Bacteria are often recognized for causing illness and fatal diseases, but many bacteria are harmless and can even serve beneficial roles in their hosts. In this doctoral work, Nelson Wang investigated both ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Currently the most promising method for capturing anthropogenic produced carbon dioxide (CO2) from suitable point sources is the technique using amines in Post-combustion CO2 Capture (PCC). However, the use of amine is ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The BAM complex in Escherichia coli is composed of five proteins, BamA-E. BamA and BamD are essential for cell viability and are required for the assembly of β-barrel outer membrane proteins. Consequently, BamA and BamD ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Background In Gram-negative bacteria, type Va and Vc autotransporters are proteins that contain both a secreted virulence factor (the “passenger” domain) and a β-barrel that aids its export. While it is known that the ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Anthropogenic pollutants produce oxidative stress in marine organisms, directly or following generation of reactive oxygen species (ROS), potentially resulting in increased accumulation of DNA strand breaks quantified. The ...

Bayesian phylogenetic estimation of clade ages supports trans-Atlantic dispersal of cichlid fishes (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Divergence-time estimation based on molecular phylogenies and the fossil record has provided insights into fundamental questions of evolutionary biology. In Bayesian node dating, phylogenies are commonly time calibrated ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract The effect of cancer therapies is often tested pre-clinically via in vitro experiments, where the post-treatment viability of the cancer cell population is measured through assays estimating the number ...
