No room for dessert: A mechanistic model of prey selection in gut-limited predatory fish
(Peer reviewed; Journal article, 2020)Predatory fish structure communities through prey pursuit and consumption and, in many marine systems, the gadoids are particularly important. These predators have flexible feeding behaviours and often feed on large prey ... -
Nodavirus in farmed Atlantic cod Gadus morhua in Norway
(Peer reviewed; Journal article, 2007-09-14)Viral encephalopathy and retinopathy (VER) was diagnosed in 5 to 24 g sized farmed Atlantic cod Gadus morhua kept in sea cages at Parisvatn, Hordaland county, on the west coast of Norway. Moderate mortality (10 to 15%) was ... -
Non-conserved C-terminal regions in the histone recognition module CW, determines specificity, stability and affinity towards monomethylated histone tails
(Master thesis, 2014-11-20)Histone modifications have an important role in epigenetic gene regulation and contribute to the cellular memory system. It has been well documented that certain patterns of histone modifications are associated with different ... -
Non-visual photoreceptive systems in early development of Atlantic halibut (Hippoglossus hippoglossus)
(Doctoral thesis, 2014-03-28)Non-visual photoreception is thought to be involved in a range of behavioural and physiological processes in teleost fishes, such as synchronisation of circadian and circannual rhythms, but also regulation of skin pigmentation, ... -
Norovirus in Pacific Oysters : Insights into Molecular Viability Assays and Mitigation Strategies to Improve Food Safety
(Doctoral thesis, 2022-11-21)Som en av de vanligste årsakene til gastroenteritt, har norovirus (NoV) vært en belastning for pasienter, helsemyndigheter og samfunnet over hele verden. Patogenet overføres gjennom inntak av infektive viruspartikler. Mange ... -
North African wetland lakes: characterization of nine sites included in the CASSARINA Project
(Peer reviewed; Journal article, 2001)Exploitation of land and water resources has increased rapidly in North Africa during the 20th century, paralleling regional population growth. As part of the CASSARINA Project (see Flower, 2001), the environmental status ... -
The Northern Lapwing (Vanellus vanellus) in Norway: Exploring the population decline through bird ringing data and habitat selection
(Master thesis, 2014-11-05)The Northern Lapwing (Vanellus vanellus) is one of many farmland birds that have been suffering from population declines as a result of agricultural intensification over the past few decades. Through the use of ringing- ... -
The Norwegian Atlantic Current in the Lofoten basin inferred from hydrological and tracer data (129I) and its interaction with the Norwegian Coastal Current
(Peer reviewed; Journal article, 2004-01-14)From three hydrological sections taken across the Lofoten Basin in May 2000, we estimated geostrophic transports of 7.2 Sv (Sverdrup = 106 m³ s-¹) for the Norwegian Atlantic Current (NAC) and its division between northern ... -
Norwegian Biology, Medicine and Psychology Undergraduate Students´ Acceptance of Modern Evolutionary Theory Using the I-SEA Survey Instrument
(Master thesis, 2017-11-02)584 undergraduate students from three disciplines and four public universities in Norway were sampled during the spring of 2014 for acceptance of modern evolutionary theory using the I-SEA survey instrument developed by ... -
Not that clean: Aquaculture-mediated translocation of cleaner fish has led to hybridization on the northern edge of the species' range
(Journal article; Peer reviewed, 2021)Translocation and introduction of non-native organisms can have major impacts on local populations and ecosystems. Nevertheless, translocations are common practices in agri- and aquaculture. Each year, millions of wild-caught ... -
Not too slow, not too fast: water currents affect group structure, aggression and welfare in post-smolt Atlantic salmon Salmo salar
(Peer reviewed; Journal article, 2016)Increased swimming speed of Atlantic salmon is generally considered an improvement to welfare under aquaculture settings, as group structure is improved and agonistic behaviour reduced. As such, establishing fish farms in ... -
Notochord development in Atlantic salmon (Salmo salar L.): exploring molecular pathways and putative mechanism of segmentation
(Doctoral thesis, 2014-03-07)Background: A key feature of the vertebrate body plan is the repeated compartments made up of individual vertebra, blood vessels, peripheral nerves and muscle. The vertebral column comprises a series of bony vertebral ... -
The notochord in Atlantic salmon (Salmo salar L.) undergoes profound morphological and mechanical changes during development
(Peer reviewed; Journal article, 2017-11)We present the development of the notochord of the Atlantic salmon (Salmo salar L.), from early embryo to sexually mature fish. Over the salmon's lifespan, profound morphological changes occur. Cells and gross structures ... -
Novel and Unexpected Microbial Diversity in Acid Mine Drainage in Svalbard (78° N), Revealed by Culture-Independent Approaches
(Peer reviewed; Journal article, 2015-10-13)Svalbard, situated in the high Arctic, is an important past and present coal mining area. Dozens of abandoned waste rock piles can be found in the proximity of Longyearbyen. This environment offers a unique opportunity for ... -
A novel human NatA N-alpha-terminal acetyltransferase complex: hNaa16p-hNaa10p (hNat2-hArd1)
(Peer reviewed; Journal article, 2009-05-29)Background: Protein acetylation is among the most common protein modifications. The two major types are post-translational Nε-lysine acetylation catalyzed by KATs (Lysine acetyltransferases, previously named HATs (histone ... -
A novel moderately thermophilic facultative methylotroph within the class Alphaproteobacteria
(Journal article; Peer reviewed, 2021-02-25)Methylotrophic bacteria (non-methanotrophic methanol oxidizers) consuming reduced carbon compounds containing no carbon–carbon bonds as their sole carbon and energy source have been found in a great variety of environments. ... -
