Parasitism and the Biodiversity-Functioning Relationship
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-15)
Species interactions can influence ecosystem functioning by enhancing or suppressing the activities of species that drive ecosystem processes, or by causing changes in biodiversity. However, one important class of species interactions – parasitism – has been little considered in biodiversity and ecosystem functioning (BD-EF) research. Parasites might increase or decrease ecosystem processes by ...
Narrow lenses for capturing the complexity of fisheries: A topic analysis of fisheries science from 1990 to 2016
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-20)
Despite increased fisheries science output and publication outlets, the global crisis in fisheries management is as present as ever. Since a narrow research focus may be a contributing factor to this failure, this study uncovers topics in fisheries research and their trends over time. This interdisciplinary research evaluates whether science is diversifying fisheries research topics in an attempt ...
Valuing coastal recreation and the visual intrusion from commercial activities in Arctic Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-04)
The coastal zone in the Arctic is being extensively used for recreational activities. Simultaneously, there is an
increasing pressure from commercial activities. We present results from a discrete choice experiment implemented
in Arctic Norway, revealing how households in this region make trade-offs between recreational
activities and commercial developments in the coastal zone. Our results show ...
Informing management strategies for a reserve: Results from a discrete choice experiment survey
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-05-18)
It is well-known that operating within the boundaries of a national park provides commercial actors with the opportunity to charge a price premium, though this has to a lesser degree been demonstrated for marine protected areas. We estimate national tourists' willingness-to-pay a price premium for boat trips in the Nha Trang Bay Marine Protected Are, Vietnam, using a discrete choice experiment. Our ...
Peptide from sea anemone metridium senile affects transient receptor potential ankyrin-repeat 1 (TRPA1) function and produces analgesic effect
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-01-11)
The Transient Receptor Potential Ankyrin-repeat 1 (TRPA1) is an important player in pain and inflammatory pathways. It is a promising target for novel drugs development for treatment of a number of pathological states. A novel peptide producing significant potentiating effect (up to ~90%) on AITC- and diclofenac-induced currents of TRPA1 was isolated from the venom of sea anemone <i>Metridium ...
Assessing the added value of the recent declaration on unregulated fishing for sustainable governance of the central Arctic Ocean
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-01-21)
The ‘Declaration concerning the prevention of unregulated high seas fishing in the central Arctic Ocean’ signed by the Arctic 5 nations, limits unregulated high seas fishing in the central part of the Arctic Ocean, and holds potential social, economic and political impacts for numerous stakeholders. In this paper, the four Interim Measures in the Declaration are discussed and what value these measures ...
Characterization of Rhamnolipids Produced by an Arctic Marine Bacterium from the Pseudomonas fluorescence Group
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-14)
The marine environment is a rich source of biodiversity, including microorganisms that have proven to be prolific producers of bioactive secondary metabolites. Arctic seas are less explored than warmer, more accessible areas, providing a promising starting point to search for novel bioactive compounds. In the present work, an Arctic marine Pseudomonas sp. belonging to the Pseudomonas (P.) fluorescence ...
The components of a food traceability system
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-03)
<p><i>Background</i>:
Traceability of food products has become the focus of regional and national legislation, of many research and technical development initiatives and projects, and of many scientific articles. However, most of the scientific publications do not differentiate between the components of a traceability system, and those who do to some degree use inconsistent terminology and definitions. ...
Catch Efficiency of Groundgears in a Bottom Trawl Fishery: A Case Study of the Barents Sea Haddock
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-10)
The catch efficiency of two types of groundgear—a conventional rockhopper and a new type of groundgear called the semicircular spreading gear (SCSG)—was investigated through experimental fishing for Haddock Melanogrammus aeglefinus conducted in the Barents Sea. A retainer bag was attached behind the footrope of the trawl, and the number of fish that were overrun by the trawl was compared with the ...
Profiling Atlantic salmon B cell populations: CpG-mediated TLR-ligation enhances IgM secretion and modulates immune gene expression
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-23)
While TLR-activated pathways are key regulators of B cell responses in mammals, their impact on teleost B cells are scarcely addressed. Here, the potential of Atlantic salmon B cells to respond to TLR ligands was shown by demonstrating a constitutive expression of nucleic-acid sensing TLRs in magnetic sorted IgM<sup>+</sup> cells. Of the two receptors recognizing CpG in teleosts, <i>tlr9</i> was the ...
