(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, 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, 2016)Recent studies suggest that previous estimates of mesopelagic biomasses are severely biased, with the new, higher estimates underlining the need to unveil behaviourally mediated coupling between shallow and deep ocean ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Crucian carp are unusual among vertebrates in surviving extended periods in the complete absence of molecular oxygen. During this time cardiac output is maintained though these mechanisms are not well understood. Using a ...
-
(Master thesis / Masteroppgave, 2023)Mapping diversity patterns across environmental gradients may predict how ecosystems will respond to climate change in the future. The soil biota, including protists, fungi and micro-invertebrates, are essential components ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Background The ballan wrasse (Labrus bergylta) belongs to a large teleost family containing more than 600 species showing several unique evolutionary traits such as lack of stomach and hermaphroditism. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Heightened inflammation, including expression of COX-2, is associated with chronic obstructive pulmonary disease (COPD) pathogenesis. The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor that is ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)European eel migrate from freshwater or coastal habitats throughout Europe to their spawning grounds in the Sargasso Sea. However, their route (∼ 6000 km) and orientation mechanisms are unknown. Several attempts have been ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Many cellular proteins are methylated on lysine residues and this has been most intensively studied for histone proteins. Lysine methylations on non-histone proteins are also frequent, but in most cases the functional ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Habitat fragmentation is a growing problem worldwide. Particularly in river systems, numerous dams and weirs hamper the movement of a wide variety of species. With the aim to preserve connectivity for fish, many barriers ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Background: Maize is the most produced crop in Sub-Saharan Africa, but yields are low and climate change is projected to further constrain smallholder production. The current efforts to breed and disseminate new high ...
-
A molecular and in planta investigation of the Q-repeat of the A. thaliana transcription factor LRP1 (Master thesis / Masteroppgave, 2023)
-
(Doctoral thesis / Doktoravhandling, 2018)Over the past ten years the massive use of genomic and transcriptomic technologies has revealed groundbreaking information about the genetic drivers of cancer in general. The knowledge of these drivers is not only fundamental ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2015)The catalytic residues in carbohydrate esterase enzyme families constitute a highly conserved triad: serine, histidine and aspartic acid. This catalytic triad is generally located in a very sharp turn of the protein backbone ...
-
(Doctoral thesis / Doktoravhandling, 2018)Skeletal muscle is a heterogeneous tissue comprised of a variety of different cell types, including the multinucleated skeletal myofiber. Although myofibers are post-mitotic, they hold a remarkable ability to adapt new ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)As ribonucleotide reductase (RNR) plays a crucial role in nucleic acid metabolism, it is an important target for anticancer therapy. The thiosemicarbazone Triapine is an efficient R2-inhibitor, which has entered about 20 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Almost all integral membrane proteins found in the outer membranes of Gram-negative bacteria belong to the transmembrane β-barrel family. These proteins are not only important for nutrient uptake and homeostasis, but are ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Abundant new ichthyosaur material has recently been documented in the Slottsmøya Member of the Agardhfjellet Formation from the Svalbard archipelago of Norway. Here we describe a partial skeleton of a new taxon, Janusaurus ...
-
(Doctoral thesis / Doktoravhandling, 2020)DNA damaging agents, such as ionizing radiation and many chemotherapeutic drugs, are used in cancer treatment to kill cancer cells. However, networks of signaling cascades induced by DNA damage counteract this by leading ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Background Advances in whole genome sequencing strategies have provided the opportunity for genomic and comparative genomic analysis of a vast variety of organisms. The analysis results are highly dependent on the quality ...
