Adipose tissue fatty acids suggest spatial and temporal dietary differences in great cormorants of the Baltic Sea area
(Journal article; Peer reviewed, 2021)Increased numbers of great cormorants (Phalacrocorax carbo) in the Baltic Sea may have local impacts on fisheries and salmonid hatcheries. We studied spatial and temporal variability in cormorant diet, and potential ... -
Adult body growth and reproductive investment vary markedly within and across Atlantic and Pacific herring: a meta-analysis and review of 26 stocks
(Journal article; Peer reviewed, 2021)Life-history traits of Pacific (Clupea pallasii) and Atlantic (Clupea harengus) herring, comprising both local and oceanic stocks subdivided into summer-autumn and spring spawners, were extensively reviewed. The main ... -
Advances in herring biology: from simple to complex, coping with plasticity and adaptability
(Peer reviewed; Journal article, 2009)At least two centuries of investigations on herring have been absorbed by scientific journals, and applied and fundamental research has produced groundbreaking concepts in fisheries, population biology, and marine ecology. ... -
Age and growth determination and stock identification using statolith microstructure of Indian squid, Loligo duvauceli
(Master thesis, 2010-05-29)Age and growth and stock identification of Indian squid, Loligo duvauceli were examined by statolith microstructure and morphological measurements. The Indian squid were sampled from the Gulf of Thailand and the Andaman ... -
Age determination of Atlantic halibut (Hippoglossus hippoglossus L.) - Size at age and regional growth differences along the coast of Norway
(Master thesis, 2011-05-25)The traditional method for estimating age of Atlantic halibut (Hippoglossus hippoglossus) is through surface readings. Previous studies have not been compared to find the best practice for surface reading techniques. Based ... -
Aggregations of foraging black guillemots (Cepphus grylle) at a sea-ice edge in front of a tidewater glacier
(Journal article; Peer reviewed, 2022)Seabirds in cold biomes sometimes aggregate near glacier fronts and at sea-ice edges to forage. In this note, we report on large aggregations of black guillemots (Cepphus grylle) at the edge of sea ice in front of the ... -
Agonistic and potentiating effects of perfluoroalkyl substances (PFAS) on the Atlantic cod (Gadus morhua) peroxisome proliferator-activated receptors (Ppars)
(Journal article; Peer reviewed, 2022)Toxicity mediated by per- and polyfluoroalkyl substances (PFAS), and especially perfluoroalkyl acids (PFAAs), has been linked to activation of peroxisome proliferator-activated receptors (Ppar) in many vertebrates. Here, ... -
Aktivering av aryl hydrokarbonreseptor (Ahr)-signalveien og lokalisering av ahr genuttrykking i tidlige livsstadier til Atlanterhavstorsk (Gadus morhua) etter eksponering for råolje
(Master thesis, 2019-09-28)Egg og larver av nordøstarktisk (NØA) torsk kan bli truet av eksponering for oljesøl dersom planene om å starte oljeutvinning i dens gyteområder utenfor kysten til Lofoten, Vesterålen og Senja (LoVeSe) realiseres. Råolje ... -
Algal toxin azaspiracid-1 induces early neuronal differentiation and alters peripherin isoform stoichiometry
(Peer reviewed; Journal article, 2015-12-14)Azaspiracid-1 is an algal toxin that accumulates in edible mussels, and ingestion may result in human illness as manifested by vomiting and diarrhoea. When injected into mice, it causes neurotoxicological symptoms and ... -
Alginate and tunicate nanocellulose composite microbeads – Preparation, characterization and cell encapsulation
(Journal article; Peer reviewed, 2022)Alginate has been used for decades for cell encapsulation. Cellulose nanofibrils (CNF) from tunicates are desirable in biomedicine due to high molecular weight, purity, crystallinity, and sustainable production. We prepared ... -
Alien plants, animals, fungi and algae in Norway:an inventory of neobiota
(Peer reviewed; Journal article, 2019-08-03)We present the results of an inventory and status assessment of alien species in Norway. The inventory covered all known multicellular neobiota, 2496 in total, 1039 of which were classified as naturalised. The latter ... -
Alien species in Norway: Results from quantitative ecological impact assessments
(Journal article, 2020)1. Due to globalisation, trade and transport, the spread of alien species is increasing dramatically. Some alien species become ecologically harmful by threatening native biota. This can lead to irreversible changes in ... -
Amino Acid Carriers of the Solute Carrier Families 7 (SLC7) and 38 (SLC38) Are Involved in Leucine Sensing in the Brain of Atlantic Salmon (Salmo salar)
(Journal article; Peer reviewed, 2021)Sensing of amino acids in fish brain, especially branched-chain amino acids (BCAA) like leucine, is involved in regulation of feed intake through different mechanisms. However, there is limited information regarding the ... -
Ammonia oxidation and oxygen consumption rate measurements in RAS at different alkalinities
(Master thesis, 2023-06-02)The need for environmentally friendly sustainable nutritious food has never been more imminent than today, with a need to increase the world´s animal-based food supply by 70% by 2050. By simply increasing the number of ... -
Ammonia-eliminating potential of Gracilaria sp. And zeolite: a preliminary study of the efficient ammonia eliminator in aquatic environment
(Peer reviewed; Journal article, 2019-02-01)High density and high feeding volume are regarded as factors causing huge accumulations of Total Ammonia Nitrogen (TAN) in an aquaculture system. An uncontrolled TAN concentration in an aquaculture system can pose a threat ... -
An amphipathic helix in Brl1 is required for nuclear pore complex biogenesis in S. cerevisiae
(Journal article; Peer reviewed, 2022)The nuclear pore complex (NPC) is the central portal for macromolecular exchange between the nucleus and cytoplasm. In all eukaryotes, NPCs assemble into an intact nuclear envelope (NE) during interphase, but the process ... -
