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 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) ... -
Brachiopod and mollusc biomineralisation is a conserved process that was lost in the phoronid–bryozoan stem lineage
(Journal article; Peer reviewed, 2022-09-19)Background: Brachiopods and molluscs are lophotrochozoans with hard external shells which are often believed to have evolved convergently. While palaeontological data indicate that both groups are descended from biomineralising ... -
Brain asymmetry is globally different in males and females: exploring cortical volume, area, thickness, and mean curvature
(Journal article; Peer reviewed, 2023)Brain asymmetry is a cornerstone in the development of higher-level cognition, but it is unclear whether and how it differs in males and females. Asymmetry has been investigated using the laterality index, which compares ... -
Brain Distribution of 10 cart Transcripts and Their Response to 4 Days of Fasting in Atlantic Salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2021-10-25)Cocaine- and amphetamine-regulated transcript (CART) has been known to be involved in feeding and energy balance in mammals, acting as an anorexigenic neuropeptide in hypothalamus. In Atlantic salmon, little is known about ... -
BRCA1 promoter methylation: the influence on gene expression and the effect of long term drug treatment
(Master thesis, 2017-07-04)Breast cancer is the most common type of cancer among woman all over the world, with over 1.67 million new cases in 2012. Heritable breast cancer is closely linked to mutations in the tumor suppressor gene BRCA1, with up ... -
