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 ...
The database of the PREDICTS (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems) project
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-12-10)
The PREDICTS project—Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)—has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used this evidence base to develop global and regional ...
Diet and metabolic state are the main factors determining concentrations of perfluoroalkyl substances in female polar bears from Svalbard
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-03)
Perfluoroalkyl substances (PFASs) have been detected in organisms worldwide, including Polar Regions. The polar bear (Ursus maritimus), the top predator of Arctic marine ecosystems, accumulates high concentrations of PFASs, which may be harmful to their health. The aim of this study was to investigate which factors (habitat quality, season, year, diet, metabolic state [i.e. feeding/fasting], breeding ...
Hiding in the background: community-level patterns in invertebrate herbivory across the tundra biome
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-03)
Invertebrate herbivores depend on external temperature for growth and metabolism. Continued warming in tundra ecosystems is proposed to result in increased invertebrate herbivory. However, empirical data about how current levels of invertebrate herbivory vary across the Arctic is limited and generally restricted to a single host plant or a small group of species, so predicting future change remains ...
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 ...
Probiotics, lactic acid bacteria and bacilli: interesting supplementation for aquaculture
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-05)
Probiotics administration in aquafeed is known to increase feed consumption and absorption due to their capacity to release a wide range of digestive enzymes and nutrients which can participate in digestion process and feed utilization, along with the absorption of diet components led to an increase in host’s health and well‐being. Furthermore, probiotics improve gut maturation, prevention of ...
Between classical and critical geopolitics in a changing Arctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-26)
Puzzled by how geographical changes in the Arctic might cause changes in state behavior the authors of this article have been inspired to return to the roots of geopolitical reasoning. By combining insights from the intellectual roots of the geopolitical tradition with empirical data on geographical changes as well as
policy changes in the Arctic today, we investigate the degree to which geopolitics, ...
The serostatus of Brucella spp., Chlamydia abortus, Coxiella burnetii and Neospora caninum in cattle in three cantons in Bosnia and Herzegovina
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-02)
Dairy production in Bosnia and Herzegovina exhibits limited productivity, which may partly, be explained by extensive reproductive problems of non-infectious and infectious origin. Brucella spp., Chlamydia abortus, Coxiella burnetii and Neospora caninum are common infectious causes of decreased reproductive outcomes in cattle worldwide. Little is, however, known about the disease status of herds ...
