(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)A variety of sex determination mechanisms can be observed in evolutionary divergent teleosts. Sex determination is genetic in Atlantic cod (Gadus morhua), however the genomic location or size of its sex-locus is unknown. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Hybridization is increasingly recognized as a potent evolutionary force. Although additive genetic variation and novel combinations of parental genes theoretically increase the potential for hybrid species to adapt, few ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Recent developments in the field of genomics have provided new and powerful insights into population structure and dynamics that are essential for the conservation of biological diversity. As a commercially highly valuable ...
-
(Doctoral thesis / Doktoravhandling, 2017)The core of this thesis has been to address the genomic basis that underlies adaptation to environmental differences in the marine environment. We use Atlantic cod (Gadus morhua L.) to enhance our understanding of several ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Speciation is a continuous process and analysis of species pairs at different stages of divergence provides insight into how it unfolds. Previous genomic studies on young species pairs have revealed peaks of divergence and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Hybridization is widespread in nature and, in some instances, can result in the formation of a new hybrid species. We investigate the genetic foundation of this poorly understood process through whole-genome analysis of ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Genomic reaction norms represent the range of gene expression phenotypes (usually mRNA transcript levels) expressed by a genotype along an environmental gradient. Reaction norms derived from common-garden experiments are ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Understanding the genetic basis of traits involved in adaptive divergence and speciation is one of the most fundamental objectives in evolutionary biology. Toward that end, we look for signatures of extreme plate loss in ...
-
Genomic stability through time despite decades of exploitation in cod on both sides of the Atlantic (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The mode and extent of rapid evolution and genomic change in response to human harvesting are key conservation issues. Although experiments and models have shown a high potential for both genetic and phenotypic change in ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Background The ShK toxin from Stichodactyla helianthus has established the therapeutic potential of sea anemone venom peptides, but many lineage-specific toxin families in Actiniarians remain uncharacterised. ...
-
(Doctoral thesis / Doktoravhandling, 2018)The genomic landscape of a hybrid species is marked by alternating regions of parental inheritance and areas of genomic constraint which form reproductive barriers. A PhD candidate at the University of Oslo has explored ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Lyme borreliosis is the most common vector-borne zoonosis in the northern hemisphere, and the pathogens causing Lyme borreliosis have distinct, incompletely described transmission cycles involving multiple host groups. The ...
-
(Master thesis / Masteroppgave, 2014)Nanotechnology is a growing industry bringing with the increasing utilization of nanoparticles (NP). NPs are defined as particles with at least one dimension being smaller than 100 nm. They are an increasing concern because ...
-
(Master thesis / Masteroppgave, 2013)Perfluorooctanoic acid (PFOA) and fluoranthene are organic pollutants with a widespread environmental occurrence. They are both present in the environment, and are known to concentrate and bioaccumulate in organisms, PFOA ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Decapod crustaceans exhibit considerable variation in fertilisation strategies, ranging from pervasive single paternity to the near-ubiquitous presence of multiple paternity, and such knowledge of mating systems and behaviour ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Voltage-gated sodium (Nav) channels constitute a prime target for drug design and discovery, given their implication in various diseases such as epilepsy, migraine and ataxia to name a few. In this regard, performing ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The subspecific taxonomy and distribution of geladas (Theropithecus gelada Rüppell, 1835) remains uncertain. Recent molecular studies based on mitochondrial sequence data revealed a geographically structured, three‐deme ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Long-term observations of ice phenology in lakes are ideal for studying climatic variation in time and space. We used a large set of observations from 1890 to 2020 of the timing of freeze-up and break-up, and the length ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)In the course of the ongoing global intensification and diversification of human pressures, the study of variation patterns of biological traits along environmental gradients can provide relevant information on the performance ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Effective communication requires a match among signal characteristics, environmental conditions, and receptor tuning and decoding. The degree of matching, however, can vary, among others due to different selective pressures ...
