Policy context as a factor of bias in the valuation of environmental goods – a dual-process theories perspective
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2018-03-13)
When ecosystem services value estimates are applied in the economic assessment of environmental policies, high accuracy of these estimates is required. One of the directions in the scientific discussion on biases in stated preference (SP) valuation surveys builds on dual-process theories of judgment. The paper contributes to this literature by presenting an experiment where two types of judgment ...
Spatio-temporal patterns of genetic variation in Arbacia lixula, a thermophilous sea urchin in expansion in the Mediterranean
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2018-06-14)
The genetic structure of 13 populations of the amphiatlantic sea urchin <i>Arbacia lixula</i>, as well as temporal genetic changes in three of these localities, were assessed using ten hypervariable microsatellite loci. This thermophilous sea urchin is an important engineer species triggering the formation of barren grounds through its grazing activity. Its abundance seems to be increasing in most ...
Simulated trawling: Exhaustive swimming followed by extreme crowding as contributing reasons to variable fillet quality in trawl-caught Atlantic cod (Gadus morhua)
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2018-07-19)
Trawl-caught Atlantic cod (<i>Gadus morhua</i>) often yield high variable fillet quality potentially related to capture stress. To investigate mechanisms involved in causing variable quality, commercial-sized (size 3.5±0.9 kg) Atlantic cod were swum to exhaustion in a large swim tunnel and exposed to extreme crowding (736±50 kg m3) for 0, 1 or 3 hours in an experimental cod-end. Further, fish were ...
Stimulation of exosome release by extracellular DNA is conserved across multiple cell types
(Journal article; Tidsskriftartikkel; Manuskript; Peer reviewed; Preprint, 2018-06-28)
Exosomes are distinguished from other types of extracellular vesicles by their small and relatively uniform size (30-100 nm) and their composition which reflects their endo-lysosomal origin. Involvement of these extracellular organelles in intercellular communication and their implication in pathological conditions has fuelled intensive research on mammalian exosomes; however, currently, very little ...
Opportunity Cost of Environmental Conservation in the Presence of Externalities: Application to the Farmed and Wild Salmon Trade-Off in Norway
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2018-08-17)
Estimation of the opportunity cost is necessary for the economic assessment of environmental conservation policies. This paper considers the case where an environmental good is negatively affected in the process of the production of marketable goods. In the presence of externalities, conservation implies the undertaking of abatement measures by polluters. A relevant measure of opportunity cost in ...
Paralithocins, Antimicrobial Peptides with Unusual Disulfide Connectivity from the Red King Crab, Paralithodes camtschaticus
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2018-01-17)
As part of an ongoing exploration of marine invertebrates as a source of new antimicrobial peptides, hemocyte extracts from the red king crab, <i>Paralithodes camtschaticus</i>, were studied. Three cationic cysteine (Cys)-rich peptides, named paralithocins 1–3, were isolated by bioassay-guided purification, and their amino acid sequences determined by Edman degradation and expressed sequences tag ...
