Vertical salmon lice behaviour as a response to environmental conditions and its influence on regional dispersion in a fjord system
(Peer reviewed; Journal article, 2014)The salmon louse Lepeophtheirus salmonis is a major parasite of salmon, and is able to travel between farms during its pelagic phases. We investigated the spatial dispersion of L. salmonis planktonic stages in the ... -
Vgll3 and the Hippo pathway are regulated in Sertoli cells upon entry and during puberty in Atlantic salmon testis
(Peer reviewed; Journal article, 2018-01-30)Vgll3 is linked to age at maturity in Atlantic salmon (Salmo salar). However, the molecular mechanisms involving Vgll3 in controlling timing of puberty as well as relevant tissue and cell types are currently unknown. Vgll3 ... -
Vgll3 knockout as a means to delay male maturity during large smolt production of Atlantic salmon (Salmo salar L.)
(Master thesis, 2023-12-01)With a 100 billion NOK export value, Atlantic salmon (Salmo salar L.) has become one of the most important export products for Norway. A highly intensified production in recirculating aquaculture systems (RAS) has pushed ... -
The vgll3 Locus Controls Age at Maturity in Wild and Domesticated Atlantic Salmon(Salmo salar L.) Males
(Peer reviewed; Journal article, 2015-11-09)Wild and domesticated Atlantic salmon males display large variation for sea age at sexual maturation, which varies between 1–5 years. Previous studies have uncovered a genetic predisposition for variation of age at maturity ... -
Vibrio splendidus virulence in experimentaly challenged cod yolk sac larvae (Gadus morhua)
(Master thesis, 2009-06-02)Farming of Atlantic cod Gadus morhua, has become an important part of Norwegian aquaculture, but disease problems are frequent. Vibriosis caused by Vibrio splendidus has caused problems in aquaculture to early life stages ... -
Vibrio tapetis from wrasse used for ectoparasite bio-control in salmon farming: Phylogenetic analysis and serotyping
(Peer reviewed; Journal article, 2017-08-09)So-called ‘cleaner fish’, including various wrasse (Labridae) species, have become increasingly popular in Norwegian salmon farming in recent years for biocontrol of the salmon louse Lepeophtheirus salmonis. Cleaner fish ... -
Viral encephalopathy and retinopathy in Atlantic salmon Salmo salar after intraperitoneal challenge with a nodavirus from Atlantic halibut Hippoglossus hippoglossus
(Peer reviewed; Journal article, 2005)Homogenate of tissue from juveniles of Atlantic halibut Hippoglossus hippoglossus suffering from viral encephalopathy and retinopathy (VER) was used to challenge smolt of Atlantic salmon Salmo salar with an initial average ... -
Viral infection switches the balance between bacterial and eukaryotic recyclers of organic matter during coccolithophore blooms
(Journal article; Peer reviewed, 2023)Algal blooms are hotspots of marine primary production and play central roles in microbial ecology and global elemental cycling. Upon demise of the bloom, organic carbon is partly respired and partly transferred to either ... -
Viral-host interactions: from strain to natural planktonic communities
(Doctoral thesis, 2017-10-13)Being the most abundant and diverse entities in planet Earth, viruses are thought to play a relevant role in controlling the composition and diversity in phytoplanktonic microbial communities. Microbial communities sustain ... -
Virulence factors of Pasteurella atlantica genomovar salmonicida and effect on salmon leucocytes
(Master thesis, 2023-11-20) -
Virus Genomes from Deep Sea Sediments Expand the Ocean Megavirome and Support Independent Origins of Viral Gigantism
(Journal article; Peer reviewed, 2019)The nucleocytoplasmic large DNA viruses (NCLDV) of eukaryotes (proposed order, “Megavirales”) include the families Poxviridae, Asfarviridae, Iridoviridae, Ascoviridae, Phycodnaviridae, Marseilleviridae, and Mimiviridae, ... -
Virus infection of Haptolina ericina and Phaeocystis pouchetii implicates evolutionary conservation of programmed cell death induction in marine haptophyte-virus interactions
(Peer reviewed; Journal article, 2014-05-05)The mechanisms by which phytoplankton cope with stressors in the marine environment are neither fully characterized nor understood. As viruses are the most abundant entities in the global ocean and represent a strong ... -
Visual predation risk and spatial distributions of large Arctic copepods along gradients of sea ice and bottom depth
(Journal article; Peer reviewed, 2023)Changes in the community size structure of Arctic copepods toward smaller and less fat individuals or species have been linked to environmental changes. The underpinning mechanisms are, however, poorly understood. We use ... -
Vital rates in early life history underlie shifts in biotic interactions along bioclimatic gradients: An experimental test of the Stress Gradient Hypothesis
(Journal article; Peer reviewed, 2021)Question The Stress Gradient Hypothesis (SGH) predicts that competition and facilitation shift along stress gradients. We ask if the underlying mechanisms operate at specific points in plant life history, and if patterns ... -
Voices of young biosphere stewards on the strengths, weaknesses, and ways forward for 74 UNESCO Biosphere Reserves across 83 countries
(Journal article; Peer reviewed, 2021)Young stakeholders are key actors in social-ecological systems, who have the capacity to be agents of sustainability transformation but are also at high risk of exclusion in the unfolding of global change challenges. Despite ... -
Vurdering av lakselusindusert villfiskdødelighet per produksjonsområde i 2016 og 2017
(Research report, 2017)Ekspertgruppen ble i mars 2017 oppnevnt for ett år for å foreta en vurdering av lakselusindusert dødelighet på villfisk i 13 produksjonsområder i Norge. En foreløpig rapport basert på data fra 2016 ble levert i april 2017 ... -
Vurderingspreferanser hos studenter i høyere utdanning
(Master thesis, 2023-06-02)I denne studien belyses vurderingspreferansene til kvinnelige, nye og førstegenerasjons-studenter, da forskning viser at de forlater STEM i større grad enn andre studenter. En av pådriverne er «high stakes» vurderinger, ... -
Warming, drought, and disturbances lead to shifts in functional composition: A millennial-scale analysis for Amazonian and Andean sites
