Effect of Diet Supplemented With Rapeseed Meal or Hydrolysable Tannins on the Growth, Nutrition, and Intestinal Microbiota in Grass Carp (Ctenopharyngodon idellus)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-25)
Grass carp (<i>Ctenopharyngodon idellus; n</i> = 320) were received four different diets for 56 days. The experimental diets were: fishmeal (FM) containing 10% fishmeal (without rapeseed meal), and rapeseed meal (RM) containing 50% rapeseed meal (without fishmeal), and two semi-purified diets either without (T0) or with 1.25% (T1) supplemental hydrolysable tannin. The approximate content of tannin ...
Interfering with neighbouring communities: Allelopathy astray in the tundra delays seedling development
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-06)
<ol>
<li>Altered species composition caused by environmental and climatic change can affect the transfer of plant residues among communities. Whereas transferred residues are typically considered a resource in recipient systems, residues of allelopathic species may instead cause interference.</li>
<li>Evergreen dwarf shrubs, specifically the allelopathic species Empetrum nigrum are increasing ...
DNA double‐strand breaks in Arctic char (Salvelinus alpinus) from Bjørnøya in the Norwegian Arctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-25)
High levels of organochlorine contaminants (OCs) have been found in arctic char (<i>Salvelinus alpinus</i>) from Lake Ellasjøen, Bjørnøya (Norwegian Arctic). The aim of the present study was to investigate the potential genotoxic effect of environmental organochlorine contaminant exposure in arctic char from Ellasjøen compared with arctic char from the low‐contaminated Lake Laksvatn nearby. Blood ...
The neglected season: Warmer autumns counteract harsher winters and promote population growth in Arctic reindeer
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-24)
Arctic ungulates are experiencing the most rapid climate warming on Earth. While concerns have been raised that more frequent icing events may cause die‐offs, and earlier springs may generate a trophic mismatch in phenology, the effects of warming autumns have been largely neglected. We used 25 years of individual‐based data from a growing population of wild Svalbard reindeer, to test how warmer ...
Lipid yield from the diatom Porosira glacialis is determined by solvent choice and number of extractions, independent of cell disruption
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-17)
Cell wall disruption is necessary to maximize lipid extraction yields in conventional species of mass-cultivated microalgae. This study investigated the effect of sonication, solvent choice and number of extractions on the lipid yield, lipid class composition and fatty acid composition of the diatom <i>Porosira glacialis</i>. For comparison, the diatom <i>Odontella aurita</i> and green alga <i>Chlorella ...
The EU block exemption and horizontal R&D agreements
(Journal article; Tidsskriftartikkel, 2020-09-24)
We analyze the effect of the European Union Competition Authority’s block exemption towards R&D cooperatives in a horizontal market structure, valid as long as the combined product market share is not too large. Two less efficient firms attempt to catch up with a technological leader, and may use the safe harbour provided by the legislation. We consider when the incentives of the R&D-performing firms ...
The Vegan Food Experience: Searching for Happiness in the Norwegian Foodscape
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-30)
The purpose of this study was to go beyond an oversimplified representation of the vegan food experience and approach the investigation of such experience, in particular of happiness deriving from food choices, including factors at the macro and micro level. Broadening the concept of foodscape to emphasize the experiential aspect of food, this study explored how the vegan food experience can be ...
Usikkerhet i koronaens tid. En studie av kulturarbeidere med ulike tilknytningsformer til arbeidslivet
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-08)
Kunst- og kulturfeltet ble hardt rammet av covid-19-pandemien. I en svært uoversiktlig situasjon i midten av april 2020 gjennomførte vi en undersøkelse blant medlemmene i Creo – Norges største interesseorganisasjon innen feltet. Respondentene erfarer større økonomisk og jobbrelatert usikkerhet på kort sikt enn usikkerhet tilknyttet jobb og karriere på lengre sikt. Selvsysselsatte opplever større ...
Bats as natural samplers: First record of the invasive pest rice water weevil Lissorhoptrus oryzophilus in the Iberian Peninsula
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-19)
We face an increasing global food security challenge as the human population continues to grow across the globe. As agricultural production rises to keep up with food demand, so too does the expansion of crop detrimental pest species. Early detection can be crucial to control their damage and relies on the use of accurate and dependable techniques. We report the first record of rice water weevil ...
The role of identity and gender in seafood cooking skills
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-16)
<i>Purpose</i> - The purpose of this study was to explore whether consumers' confidence in cooking skills related to seafood differed across genders, and if such difference could be explained by the identity-relevance of seafood cooking for men.<p>
<p><i>Design/methodology/approach</i> - Survey data was collected from a balanced sample of 515 Norwegian consumers.<p>
<p><i>Findings</i> - The ...
