How Honey Bee Vitellogenin Holds Lipid Cargo: A Role for the C-Terminal
(Journal article; Peer reviewed, 2022-06-09)Vitellogenin (Vg) is a phylogenetically broad glycolipophosphoprotein. A major function of this protein is holding lipid cargo for storage and transportation. Vg has been extensively studied in honey bees (Apis mellifera) ... -
How microbial food web interactions shape the arctic ocean bacterial community revealed by size fractionation experiments
(Journal article; Peer reviewed, 2021-11-17)In the Arctic, seasonal changes are substantial, and as a result, the marine bacterial community composition and functions differ greatly between the dark winter and light-intensive summer. While light availability is, ... -
How to obtain clear images from in-trawl cameras near the seabed? A case study from the Barents Sea demersal fishing grounds
(Journal article; Peer reviewed, 2023)Underwater camera systems are commonly used for monitoring fish and fishing gear behaviours. More recently, camera systems have been applied to scientific trawl surveys for improved spatial resolution and less invasive ... -
How trophic cascades and photic zone nutrient content interact to generate basin-scale differences in the microbial food web
(Journal article; Peer reviewed, 2020)In linear food chains, resource and predator control produce positive and negative correlations, respectively, between biomass at adjacent trophic levels. These simple relationships become more complex in food webs that ... -
The human dimension of biodiversity changes on islands
(Journal article; Peer reviewed, 2021)Islands are among the last regions on Earth settled and transformed by human activities, and they provide replicated model systems for analysis of how people affect ecological functions. By analyzing 27 representative ... -
The Human N-Alpha-Acetyltransferase 40 (hNaa40p/ hNatD) Is Conserved from Yeast and N-Terminally Acetylates Histones H2A and H4
(Peer reviewed; Journal article, 2011-09-15)Protein Na-terminal acetylation (Nt-acetylation) is considered one of the most common protein modification in eukaryotes, and 80-90% of all soluble human proteins are modified in this way, with functional implications ... -
The human NAD metabolome: Functions, metabolism and compartmentalization
(Peer reviewed; Journal article, 2015)The metabolism of NAD has emerged as a key regulator of cellular and organismal homeostasis. Being a major component of both bioenergetic and signaling pathways, the molecule is ideally suited to regulate metabolism and ... -
Human-induced evolution caught in action: SNP-array reveals rapid amphi-atlantic spread of pesticide resistance in the salmon ecotoparasite Lepeophtheirus salmonis
(Peer reviewed; Journal article, 2014-10-26)Background: The salmon louse, Lepeophtheirus salmonis, is an ectoparasite of salmonids that causes huge economic losses in salmon farming, and has also been causatively linked with declines of wild salmonid populations. ... -
Hypothalamic agrp and pomc mRNA Responses to Gastrointestinal Fullness and Fasting in Atlantic Salmon (Salmo salar, L.)
(Journal article; Peer reviewed, 2020-02-11)The orexigenic agouti-related protein (AgRP) and the anorexigenic pro-opiomelanocortin (POMC) are crucial players in the control of feed intake in vertebrates, yet their role in teleosts has not been fully established. ... -
Hypoxia tolerance and responses to hypoxic stress during heart and skeletal muscle inflammation in Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2017-07-11)Heart and skeletal muscle inflammation (HSMI) is associated with Piscine orthoreovirus (PRV) infection and is an important disease in Atlantic salmon (Salmo salar) aquaculture. Since PRV infects erythrocytes and farmed ... -
Hypoxia tolerance thresholds for post-smolt Atlantic salmon: Dependency of temperature and hypoxia acclimation
(Journal article, 2013-12-05)Atlantic salmon (Salmo salar L.) experience periodic drops in dissolved oxygen (O2) inside aquaculture sea cages. In order to evaluate whether fish function or welfare is compromised during such drops in O2 (termed hypoxia), ... -
Ice-algal carbon supports harp and ringed seal diets in the European Arctic: evidence from fatty acid and stable isotope markers
(Journal article; Peer reviewed, 2021)Sea-ice declines in the European Arctic have led to substantial changes in marine food webs. To better understand the biological implications of these changes, we quantified the contributions of ice-associated and pelagic ... -
Ichthyobodo hippoglossin. sp. (Kinetoplastea: Prokinetoplastida: Ichthyobodonidae fam. nov.), an ectoparasitic flagellate infecting farmed Atlantic halibut Hippoglossus hippoglossus
(Peer reviewed; Journal article, 2007-01-18)Diseased Atlantic halibut Hippoglossus hippoglossus juveniles from a hatchery in western Norway showed gill and skin infections with an Ichthyobodo species. Genus Ichthyobodo contains a single valid species, I. necator, ... -
Ichthyobodo infections on farmed and wild fish. Methods for detection and identification of Ichthyobodo spp.
(Doctoral thesis, 2013-03-01)Ichthyobodosis is an important parasitic disease that has caused severe loss among ornamental and farmed fish world wide for more than a century. The disease is caused by heavy infections on skin and gills by parasitic ... -
Identification and characterisation of novel SNP markers in Atlantic cod: Evidence for directional selection
(Peer reviewed; Journal article, 2008-02-26)Background The Atlantic cod (Gadus morhua) is a groundfish of great economic value in fisheries and an emerging species in aquaculture. Genetic markers are needed to identify wild stocks in order to ensure sustainable ... -
