The biological indicators and temporal spawning habits of wrasse (Family: Labridae) from Sunnhordland
(Master thesis, 2015-06-15)The salmonid industry in Norway has grown exponentially. The greatest cost and danger to the salmonid industry are ectoparasitic sea lice (Lepeophtheirus salmonis). Sea lice attach to salmon causing damage and increasing ... -
Biological transformation of Arctic dissolved organic matter in a NE Greenland fjord
(Peer reviewed; Journal article, 2018-12-07)Arctic waters are often enriched with terrestrial dissolved organic matter (DOM) characterized by having elevated visible wavelength fluorescence (commonly termed humic-like). Here, we have identified the sources of ... -
Biology and distribution patterns of some deepwater demersal fishes in the North Atlantic, with special reference to Antimora rostrata A study related to the project “Patterns and Processes of the ecosystems of the northern Mid-Atlantic”, MAR-ECO, 2001-2008
(Doctoral thesis, 2007-06-19)The study seeks to increase our knowledge on deepwater demersal fish assemblages and the biological adaptations of Antimora rostrata. This widespread deep-living demersal teleost is essentially used as an example species. ... -
Biology students at work: using blogs to investigate personal epistemologies
(Peer reviewed; Journal article, 2018-12-24)This paper reports an investigation of biology students’ discussion of knowing in work placements, as accounted in blogs. Twenty-two blogs, containing 78 individual entries, written in conjunction with a work placement ... -
Biomass of Scyphozoan Jellyfish, and Its Spatial Association with 0-Group Fish in the Barents Sea
(Peer reviewed; Journal article, 2012-03-22)An 0-group fish survey is conducted annually in the Barents Sea in order to estimate fish population abundance. Data on jellyfish by-catch have been recorded since 1980, although this dataset has never been analysed. In ... -
Bioorthogonal Non-canonical Amino Acid Tagging Combined With Flow Cytometry for Determination of Activity in Aquatic Microorganisms
(Journal article; Peer reviewed, 2020)In this study, we have combined bioorthogonal non-canonical amino acid tagging (BONCAT) and flow cytometry (FCM) analysis, and we demonstrate the applicability of the method for marine prokaryotes. Enumeration of active ... -
Bioprospecting North Atlantic microalgae with fast growth and high polyunsaturated fatty acid (PUFA) content for microalgae-based technologies
(Peer reviewed; Journal article, 2017-09)Microalgae are considered to be an important and sustainable alternative to fish oil as a source for the polyunsaturated fatty acids (PUFAs) eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Due to their health ... -
The biosynthesis of phospholipids is linked to the cell cycle in a model eukaryote
(Journal article; Peer reviewed, 2021)The structural challenges faced by eukaryotic cells through the cell cycle are key for understanding cell viability and proliferation. We tested the hypothesis that the biosynthesis of structural lipids is linked to the ... -
Biotic rescaling reveals importance of species interactions for variation in biodiversity responses to climate change
(Journal article; Peer reviewed, 2020)Generality in understanding biodiversity responses to climate change has been hampered by substantial variation in the rates and even directions of response to a given change in climate. We propose that such context ... -
Biotyping reveals loss of motility in two distinct Yersinia ruckeri lineages exclusive to Norwegian aquaculture
(Journal article; Peer reviewed, 2022)Non-motile strains of Yersinia ruckeri, known as Y. ruckeri biotype 2, now dominate amongst clinical isolates retrieved from rainbow trout internationally. Due to an acute increase in the number of yersiniosis cases in ... -
Bivalve mollusks as tools for monitoring antibiotic resistance in the marine environment
(Doctoral thesis, 2020-04-29)Antibiotic resistance (AR) is a major global health concern, especially in clinical and veterinary settings. Environmental niches, including the aquatic environment, serve as a source of and/or a dissemination route for ... -
Black soldier fly larvae meal can replace fish meal in diets of sea-water phase Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2018-12-12)A feeding trial was conducted to test the growth potential, nutritional utilization, liver health and fillet sensory parameters of sea-water Atlantic salmon (Salmo salar L.) fed diets with increasing substitution of fish ... -
Blue mussel (Mytilus edulis) silage, a possible low trophic marine protein source for Atlantic salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2024)Blue mussel (Mytilus edulis) could be a promising marine protein source in fish feeds and is of great interest since it can be cultivated along the Norwegian coastline. However, the use of blue mussels in feeds is dependent ... -
Blue mussels in western Norway have vanished where in reach of crawling predators
(Journal article; Peer reviewed, 2023)Blue mussels (Mytilus spp.) are declining around the world. In western Norway, they have widely disappeared from rocky shores but still thrive on floating structures. Other refugia are cracks in rocks, exposed sites, and ... -
A Blueprint for an Inclusive, Global Deep-Sea Ocean Decade Field Program
(Journal article; Peer reviewed, 2020)The ocean plays a crucial role in the functioning of the Earth System and in the provision of vital goods and services. The United Nations (UN) declared 2021–2030 as the UN Decade of Ocean Science for Sustainable Development. ... -
Body size adaptions under climate change: Zooplankton community more important than temperature or food abundance in model of a zooplanktivorous fish
(Journal article; Peer reviewed, 2020)One of the most well-studied biogeographic patterns is increasing body size with latitude, and recent body size declines in marine and terrestrial organisms have received growing attention. Spatial and temporal variation ... -
Body-snatcher from the deep? The effect of the parasitic copepod, Sarcotretes scopeli (Jungersen, 1911), on its mesopelagic fish host.
(Master thesis, 2022-06-30)Benthosema glaciale (Reinhardt, 1837) is one of the most abundant fish species found globally. The species plays an important role in the food-web of marine ecosystems, as a link between the trophic levels. In west Norwegian ... -
Bootstrapping outperforms community-weighted approaches for estimating the shapes of phenotypic distributions
(Journal article; Peer reviewed, 2023)1. Estimating phenotypic distributions of populations and communities is central to many questions in ecology and evolution. These distributions can be characterized by their moments (mean, variance, skewness and kurtosis) ... -
