Assessing and comparing climatic control on distribution and reproduction of alpine and lowland species in the subalpine habitat of western Norway.
(Doctoral thesis, 2012-02-06)Aims and background: Species range shift is among the most well-documented responses to climate change. As a result, a growing number of studies model species climatic niches to predict how species ranges may displace in ... -
Assessing mackerel behaviour following crowding-induced stress in purse seine fisheries
(Master thesis, 2016-06-01)The practice of slipping in purse seine fisheries has been shown to cause high levels of delayed mortality in released fish. This unaccounted mortality could lead to bias in stock assessments, and brings the sustainability ... -
Assessing microplastic as a vector for chemical entry into fish larvae using a novel tube-feeding approach
(Journal article; Peer reviewed, 2021)A tube-feeding model for administering microplastic (MP, Ø = 30 μm) spheres to fish larvae was employed to quantify the uptake of hydrophobic organic contaminants (HOCs) into the larval body through a single administration ... -
Assessing mineral availability in fish feeds using complementary methods demonstrated with the example of zinc in atlantic salmon
(Journal article; Peer reviewed, 2021)Assessing the availability of dietary micro-minerals is a major challenge in mineral nutrition of fish species. The present article aims to describe a systematic approach combining different methodologies to assess the ... -
Assessing sampling coverage of species distribution in biodiversity databases
(Peer reviewed; Journal article, 2019)Aim: Biodiversity databases are valuable resources for understanding plant species distributions and dynamics, but they may insufficiently represent the actual geographic distribution and climatic niches of species. Here ... -
Assessing the effectiveness of an electricalstunning and chilling protocol for theslaughter of Atlantic mackerel (Scomber scombrus)
(Peer reviewed; Journal article, 2019-09-04)Inducing unconsciousness in fish using electrical stunning prior to slaughter may improve fish welfare and fillet quality if such practises can be disseminated into wild capture fisheries. The objectives of this study were ... -
Assessing the exploitation status of main fisheries resources in Ghana’s reservoirs based on reconstructed catches and a length-based bootstrapping stock assessment method
(Peer reviewed; Journal article, 2019)Abobi SM, Mildenberger TK, Kolding J, Wolff M. 2019. Assessing the exploitation status of main fisheries resources in Ghana’s reservoirs based on reconstructed catches and a length-based bootstrapping stock assessment ... -
Assessing the performance of statistical classifiers to discriminate fish stocks using Fourier analysis of otolith shape
(Peer reviewed; Journal article, 2020)The assignment of individual fish to its stock of origin is important for reliable stock assessment and fisheries management. Otolith shape is commonly used as the marker of distinct stocks in discrimination studies. Our ... -
Assessing the relation between geodiversity and species richness in mountain heaths and tundra landscapes
(Journal article; Peer reviewed, 2023)Context Recent studies show that geodiversity—the diversity of Earth's landforms, materials, and processes—has a positive relationship with biodiversity at a landscape scale. However, there is a substantial lack of evidence ... -
Assessing the reproductive biology of the Greenland shark (Somniosus microcephalus)
(Journal article; Peer reviewed, 2020)The Greenland shark (Somniosus microcephalus, Squaliformes: Somniosidae) is a long-lived Arctic top predator, which in combination with the high historical and modern fishing pressures, has made it subject to increased ... -
Assessment of a decontamination process for dioxins anddioxin-like PCBs in fish oil by physical filtration withactivated carbon
(Peer reviewed; Journal article, 2017-07)Following a request from the European Commission, the EFSA Panel on Contaminants in the Food Chain (CONTAM) provided a scientific opinion on the assessment of a decontamination process consisting in the adsorption with ... -
Assessment of growth performance and liver lipid accumulation in Atlantic salmon (Salmo salar) fed an insect-based diet
(Master thesis, 2018-06-26)Increase in price and reduced availability of fish meal (FM) has caused the aquaculture industry to look at alternative sources for nutrients for feed production. Vegetable protein sources can replace a substantial part ... -
Assessment of the biodegradability of xanthan in offshore injection water
(Master thesis, 2015-04-29)The application of biopolymers in EOR operations is considered environmental friendly compared to synthetic polymers. However, microbial degradation of the biopolymers may lead to a deterioration of effect in EOR applications. ... -
Assessment of the carbon monoxide metabolism of the hyperthermophilic sulfate-reducing archaeon Archaeoglobus fulgidus VC-16 by comparative transcriptome analyses
(Peer reviewed; Journal article, 2015)The hyperthermophilic, sulfate-reducing archaeon, Archaeoglobus fulgidus, utilizes CO as an energy source and it is resistant to the toxic effects of high CO concentrations. Herein, transcription profiles were obtained ... -
Associated bacteria of Botryococcus braunii (Chlorophyta)
(Peer reviewed; Journal article, 2019-03-27)Botryococcus braunii (Chlorophyta) is a green microalga known for producing hydrocarbons and exopolysaccharides (EPS). Improving the biomass productivity of B. braunii and hence, the productivity of the hydrocarbons and ... -
Asynchronous Accumulation of Organic Carbon and Nitrogen in the Atlantic Gateway to the Arctic Ocean
(Peer reviewed; Journal article, 2018-11-15)Nitrogen (N) is the main limiting nutrient for biological production in the Arctic Ocean. While dissolved inorganic N (DIN) is well studied, the substantial pool of N bound in organic matter (OM) and its bioavailability ... -
At what cost? Attempting to quantify cost of resistance in bacterium-phage interactions
(Doctoral thesis, 2023-12-15)Biodiversiteten i mikrobielle samfunn er svært stor. Organismene som danner samfunnet må stadig gjøre avveininger mellom ulike karaktertrekk som påvirker deres muligheter for vekst, konkurranse og overlevelse. For å beskrive ... -
Atlantic bluefin tuna spawn early to avoid metabolic meltdown in larvae
(Journal article; Peer reviewed, 2022)To predict shifts in phenology and distribution of organisms we need to understand how survival through early life stages depends on environmental conditions. Here, we present a mechanistic model of development, feeding ... -
