Redox control of protein degradation
(Peer reviewed; Journal article, 2015-12)Intracellular proteolysis is critical to maintain timely degradation of altered proteins including oxidized proteins. This review attempts to summarize the most relevant findings about oxidant protein modification, as well ... -
Redox regulation in Atlantic cod (Gadus morhua) embryos developing under normal and heat-stressed conditions
(Peer reviewed; Journal article, 2013-04)With regard to predicted oceanic warming, we studied the effects of heat stress on the redox system during embryonic development of Atlantic cod (Gadus morhua), with emphasis on the glutathione balance, activities of key ... -
Reduced physiological plasticity in a fish adapted to stable temperatures
(Journal article; Peer reviewed, 2022)Plasticity can allow organisms to maintain consistent performance across a wide range of environmental conditions. However, it remains largely unknown how costly plasticity is and whether a trade-off exists between plasticity ... -
Reducing Wooden Structure and Wildland-Urban Interface Fire Disaster Risk through Dynamic Risk Assessment and Management
(Journal article; Peer reviewed, 2020-03-18)In recent years, severe and deadly wildland-urban interface (WUI) fires have resulted in an increased focus on this particular risk to humans and property, especially in Canada, USA, Australia, and countries in the ... -
Refinement of a radioreceptor binding assay for nicotinic acid adenine dinucleotide phosphate
(Peer reviewed; Journal article, 2007-12-01)The measurement of changes in nicotinic acid adenine dinucleotide phosphate (NAADP) levels in cells has been, and remains, key to the investigation of the functions of NAADP as a Ca2+-releasing second messenger. Here we ... -
Reflections on the Use of Ecological Attributes and Traits in Quaternary Botany
(Journal article; Peer reviewed, 2020)There has been an upsurge of interest and research activity in trait-based approaches in ecology, biogeography, and macroecology. I discuss if this upsurge has impacted Quaternary botany (the study of plant remains preserved ... -
Regional climate model simulations for Europe at 6k and 0.2k years BP: sensitivity to changes in anthropogenic deforestation
(Peer reviewed; Journal article, 2014-03-28)This study aims to evaluate the direct effects of anthropogenic deforestation on simulated climate at two contrasting periods in the Holocene, ~6 and ~0.2 k BP in Europe. We apply We apply the Rossby Centre regional climate ... -
Regional Expression of npy mRNA Paralogs in the Brain of Atlantic Salmon (Salmo salar, L.) and Response to Fasting
(Journal article; Peer reviewed, 2021-08-26)Neuropeptide Y (NPY) is known as a potent orexigenic signal in vertebrates, but its role in Atlantic salmon has not yet been fully established. In this study, we identified three npy paralogs, named npya1, npya2, and npyb, ... -
Regional impact from fin-fish farming in an intensive production area (Hardangerfjord, Norway)
(Peer reviewed; Journal article, 2014)The Hardangerfjord is one of the largest salmon-farming areas in Norway, with an annual production of approximately 70,000 metric tonnes. The regional impact of fin-fish farming in a fjord environment was studied during ... -
Regulation of appetite and growth of Atlantic salmon (Salmo salar L.) and effect of water oxygen, temperature and dietary energy
(Doctoral thesis, 2017-06-27)High water temperature combined with low dissolved oxygen (LO or hypoxia) is one of the most challenging environmental conditions farmed fish experience. The oxygen requirement of fish increases in parallel to this, which ... -
Reindeer trampling promotes vegetation changes in tundra heathlands: Results from a simulation experiment
(Journal article; Peer reviewed, 2020)Question Herbivores exert strong influences on vegetation through activities such as trampling, defoliation, and fertilization. The combined effect of these activities on plant performance may cause dramatic vegetation ... -
Reintroduction of dj-1 in müller cells inhibits retinal degeneration in the dj-1 deficient retina
(Journal article; Peer reviewed, 2021)The eye is continuously under oxidative stress due to high metabolic activity and reactive oxygen species generated by daily light exposure. The redox-sensitive protein DJ-1 has proven to be essential in order to protect ... -
Relationship between viral dose and outcome of infection in Atlantic salmon, Salmo salar L., post-smolts bath-challenged with salmonid alphavirus subtype 3
(Peer reviewed; Journal article, 2016-10-19)Salmonid alphavirus subtype 3 (SAV3) causes pancreas disease (PD) and adversely affects salmonid aquaculture in Europe. A better understanding of disease transmission is currently needed in order to manage PD outbreaks. ... -
Relationships between calibrated ages and depth in stratigraphical sequences: an estimation procedure by mixed-effect regression
(Peer reviewed; Journal article, 2005)We present a procedure for estimating age-depth relationships in stratigraphical sequences by means of a generalized mixed-effect regression using an ancillary function for the partitioning of the fixed effect and the ... -
Relationships between spawning ground identity, Latitude and early life thermal exposure in Northeast Arctic Cod
(Peer reviewed; Journal article, 2008)from its feeding grounds in the Barents Sea to various spawning banks along the Norwegian coast. Prior to the 1990s these banks were located on a wide latitudinal range from Finnmark (~71º N) to Møre (~63º N), or even to ... -
The Relative Effect of Team-Based Learning on Motivation and Learning: A Self-Determination Theory Perspective
(Peer reviewed; Journal article, 2017)We investigate the effects of team-based learning (TBL) on motivation and learning in a quasi-experimental study. The study employs a self-determination theory perspective to investigate the motivational effects of ... -
Relative transcript quantification by Quantitative PCR: Roughly right or precisely wrong?
(Journal article; Peer reviewed, 2005-04-26)Background When estimating relative transcript abundances by quantitative real-time PCR (Q-PCR) we found that the results can vary dramatically depending on the method chosen for data analysis. Results Analyses of ... -
