The role of trust in sustainable management of land, fish, and wildlife populations in the Arctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-01)
Sustainable resource management depends on support from the public and local stakeholders. Fish, wildlife, and land management in remote areas face the challenge of working across vast areas, often with limited resources, to monitor land use or the status of the fish-and-wildlife populations. Resource managers depend on local residents, often Indigenous, to gain information about environmental ...
The antimicrobial effect of CEN1HC-Br against Propionibacterium acnes and its therapeutic and anti-inflammatory effects on acne vulgaris
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-12-03)
Propionibacterium acnes is a commensal bacterium, which is involved in acne inflammation. An antimicrobial peptide named CEN1HC-Br, which was isolated and characterized form the green sea urchin, has been shown to possess broad-spectrum antibacterial activity. Little is known concerning the potential effects of its antibacterial and anti-inflammatory properties against P. acnes. To examine the potency ...
Holistic Assessment of Rumen Microbiome Dynamics through Quantitative Metatranscriptomics Reveals Multifunctional Redundancy during Key Steps of Anaerobic Feed Degradation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-07)
Ruminant livestock is a major source of the potent greenhouse gas methane. The complex rumen microbiome, consisting of bacteria, archaea, and microbial eukaryotes, facilitates anaerobic plant biomass degradation in the cow rumen, leading to methane emissions. Using an integrated approach combining multidomain quantitative metatranscriptomics with gas and volatile fatty acid (VFA) profiling, we ...
Creativity in Science - Scientific Essay
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-13)
Modern science is expected to generate new knowledge and understanding. In this scientific essay, I wish to explore the field of creativity in science by contributing a theoretical perspective on creativity and the creative process, which will include exemplifying different factors that promote or inhibit creativity, as well as reflecting on creativity in my own research project. In addition, I ...
On the numerous concepts in invasion biology
(Journal article; Tidsskriftartikkel; Peer reviewed, 2006-01-20)
The study of biological invasions has triggered the production of a diversity of concepts. The terminology has, however, often been applied inconsistently and inaccurately. This article lists and assesses the most commonly used terms and concepts in invasion ecology. In each case the most coherent definition and use is suggested.
Biogenic silica production and diatom dynamics in the Svalbard region during spring
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-06)
Diatoms are generally the dominant contributors to the Arctic Ocean spring bloom, which is a key event in regional food webs in terms of capacity for secondary production and organic matter export. Dissolved silicic acid is an obligate nutrient for diatoms and has been declining in the European Arctic since the early 1990s. The lack of regional silicon cycling information precludes understanding the ...
Functional roles and redundancy of demersal Barents Sea fish: Ecological implications of environmental change
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-21)
When facing environmental change and intensified anthropogenic impact on marine ecosystems, extensive knowledge of how these systems are functioning is required in order to manage them properly. However, in high-latitude ecosystems, where climate change is expected to have substantial ecological impact, the ecosystem functions of biological species have received little attention, partly due to the ...
External damage to trawl-caught Northeast arctic cod (Gadus morhua): Effect of codend design
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-02-22)
The purpose of this study was to investigate the extent of external damage (gear marks, pressure injuries, ecchymosis and skin abrasion) present on trawl-caught cod (Gadus morhua) and to examine whether the extent of damage could be reduced by introducing changes in the gear. We tested whether changing the 2-panel knotted codend used by the Norwegian trawler fleet operating in the Barents Sea today ...
How vulnerable is the European seafood production to climate warming?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-16)
The main challenge for the European seafood industry is to ensure sustainable production volume while adapting to climate warming. Marine fisheries mainly target 41 species which account for 80% of the seafood production in Europe. The remaining 20% comes from marine and freshwater aquaculture, which harvest mainly 5 and 11 species, respectively. European seafood production volume (2004–2014) recorded ...
Characterization of Microbial Communities in Pilot-Scale Constructed Wetlands with Salicornia for Treatment of Marine Aquaculture Effluents
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-29)
Microorganisms play an essential role in the performance of constructed wetlands (CWs) for wastewater treatment. However, there has been limited discussion on the characteristics of microbial communities in CWs for treatment of effluents from marine recirculating aquaculture systems (RAS). This study is aimed at characterizing the microbial communities of pilot-scale CWs with <i>Salicornia bigelovii</i> ...
