Are they experts? Self-assessed backcountry skills among backcountry skiers in Norway and North America
(Conference object; Konferansebidrag, 2018)We analyze how backcountry skiers’ perceived ability to manage avalanche terrain correlate with more objective measures of experience and skills, among 1209 backcountry riders in Norway and North America. We further analyze if self-assessed backcountry skills are affected by past experience of avalanches and close calls, risk attitudes, and demographics. Our results suggest that self-assessed skill ... -

The results demonstrate the complex interactions of these water quality variables. The specific growth rate (SGR) of the lumpfish was progressively ... -
Marine-derived products as functional feed additives in aquaculture: A review
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-27)The aquaculture industry is expanding to meet the daily requirements of humanity from high-quality seafood. In this regard, intensive aquaculture systems are suggested, resulting in high production but being challenged with immunosuppression and disease invaders. Antibiotics were used for a long time to protect and treat aquatic animals; however, continuous use led to severe food safety issues, ... -
Validation of pop-up satellite archival tags (PSATs) on Atlantic cod (Gadus morhua) in a Greenland fjord
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-28)Traditional tagging techniques are simple and cost-effective, but inferences require recaptures and data on movement/migration are limited to a start and end position at unpredictable intervals. Pop-up satellite archival tags (PSATs) offer other opportunities, as they provide positions at pre-programmed times and collect on-route data, which can be used to describe position, behavior, and habitat ... -
Diversity and ecology of aphyllophoroid fungi on driftwood logs on the shores of the Baltic Sea
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-26)Driftwood is woody debris that is floating on the sea or brought onto the shore by the sea. It can have a natural origin but often it originates from human activities. Driftwood has a significant ecological role as a microhabitat for a large range of species. Dead-wood-associated aphyllophoroid fungi on driftwood have been studied rather little globally, and there are hardly any studies conducted ... -
Determination of pH in pre rigor fish muscle - method matters
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-06)The determination of post mortem muscle pH are often carried out in studies on how pre-slaughter handling influences the development of rigor mortis and the quality of the fish products. The analysis might be performed by inserting a pH-electrode into the intact flesh or using a suspension containing a minced muscle sample. Although it has been known for a long time that mincing muscle tissue ... -
Contagious behaviour or not? Tourists' skills and practices in a Norwegian church
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-23)Tourist-to-tourist interaction takes place in many forms at attractions such as museums, churches and historical sites. In many settings, this interaction is a well-functioning part of the tourist experience, where tourists conform to the social norms that govern the attraction. However, interaction with other tourists can also devalue the experience; their presence may be perceived as challenging ... -
Analyzing the Geometry and Dynamics of Viral Structures: A Review of Computational Approaches Based on Alpha Shape Theory, Normal Mode Analysis, and Poisson–Boltzmann Theories
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-13)The current SARS-CoV-2 pandemic highlights our fragility when we are exposed to emergent viruses either directly or through zoonotic diseases. Fortunately, our knowledge of the biology of those viruses is improving. In particular, we have more and more structural information on virions, i.e., the infective form of a virus that includes its genomic material and surrounding protective capsid, and ... -
Research progress on gut health of farmers teleost fish: a viewpoint concerning the intestinal mucosal barrier and the impact of its damage
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-05)The intestinal mucosal barrier plays a critical role in the maintenance of host health. In farmed teleost fish, the intestinal epithelium is challenged by a number of factors, leading to damage of the intestinal mucosal barrier. The pathogenesis of intestinal mucosal barrier damage in most farmed teleost fish has been associated with cell death, mainly including apoptosis, pyroptosis, necroptosis ... -
Responding to global warming: New fisheries management measures in the Arctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-01)The northernmost commercial fisheries in the world take place in the northern Barents Sea up to around 80° N. This is an area where global warming is particularly intense and where large, previously ice-covered areas are now more accessible to fishing vessels. This raised questions whether existing conservation and management measures are adequate. In this paper, we discuss the process of developing ... -
Estimating Surface Concentrations of Calanus finmarchicus Using Standardised Satellite-Derived Enhanced RGB Imagery
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-08)Calanus finmarchicus is a keystone zooplankton species that is commercially harvested and is critical in sustaining many important fisheries in the North Atlantic. However, due to their patchy population distributions, they are notoriously difficult to map using traditional ship-based techniques. This study involves the use of a combined approach of standardized ocean colour imagery and radiative ... -
Weak seasonality in benthic food web structure within an Arctic inflow shelf region
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-23)The Arctic Ocean is characterized by pronounced seasonality in the quantity and quality of organic matter exported from the surface ocean. While it is well established that changes in food availability can alter the abundance, biomass and function of benthic organisms, the impact on food web structure is not well studied. We used bulk carbon and nitrogen stable isotope analysis to assess the quantity ... -
The Image Fallacy: Rethinking the Tragedy of the Commons
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-05)An image is what we have in our head and what we make up in an allegory, a name, a metaphor, a text, a map or in a drawing. None of these should be confused with the thing that is being imagined. They are not the real thing, just our imaginations of it. Still, we could not do without them, for instance when governing small-scale fisheries. They make us understand what we are up to and the track we ... -
Trust-based management control in inter-organizational relationships
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-05)High levels of trust can reduce the risk of inter-organizational relationships failing. Also, high levels of trust between business partners can be advantageous as less time and effort are spent controlling the motives and behavior of a company’s counterpart. This case study explores the management control systems between two small Norwegian salmon farming companies engaged in a joint venture. ... -
