Increasing the levels of the essential trace elements Se, Zn, Cu and Mn in rotifers (Brachionus plicatilis) used as live feed
(Peer reviewed; Journal article, 2013-03-04)Rotifers are a common first feeding diet for rearing marine fish larvae. However, the levels of Mn, Cu, Zn, Se and iodine found in rotifers are low and may be insufficient to meet larval fish requirements. This study ... -
Independent losses of a xenobiotic receptor across teleost evolution
(Peer reviewed; Journal article, 2018-07-10)Sensitivity to environmental stressors largely depend on the genetic complement of the organism. Recent sequencing and assembly of teleost fish genomes enable us to trace the evolution of defense genes in the largest and ... -
Indigenous Ammonia-Oxidizing Archaea in Oxic Subseafloor Oceanic Crust
(Journal article, 2020-03-10)Oceanic ridge flank systems represent one of the largest and leastexplored microbial habitats on Earth. Fundamental ecological questions regarding community activity, recruitment, and succession in this environment remain ... -
Indiscriminately Loving Sticklebacks. A test of assortative mate preferences between two morphologically diverged parapatric populations of threespine stickleback (Gasterosteus aculeatus L.) concerning pelvic reduction
(Master thesis, 2013-06-07)Two parapatric populations in western Norway in which one have completely reduced its pelvic complex are tested for assortative mating being an important mechanism in maintaining barriers keeping them from mixing in their ... -
Individual habitat transitions of Atlantic herring Clupea harengus in a human-modified coastal system
(Peer reviewed; Journal article, 2015-02-03)Pelagic marine fish often display highly dynamic migration patterns. However, such movement behaviour is usually studied at the population or school level, while less is known about individual movement characteristics and ... -
Individual variation in competitive performance in juvenile cod

Individual-based model highlights the importance of trade-offs for virus-host population dynamics and long-term coexistence
(Journal article; Peer reviewed, 2022)Viruses play diverse and important roles in ecosystems. In recent years, trade-offs between host and virus traits have gained increasing attention in viral ecology and evolution. However, microbial organism traits, and ... -
Induction of tenacibaculosis in Atlantic salmon smolts using Tenacibaculum finnmarkense and the evaluation of a whole cell inactivated vaccine
(Peer reviewed; Journal article, 2018-10)Tenacibaculosis, an ulcerative disease characterised by skin lesions, mouth erosion, frayed fins and tail rot, is a significant fish welfare issue in marine aquaculture worldwide. The disease is a concern to the Atlantic ... -
The infection cycle of Marteilia pararefringens in blue mussels, Mytilus edulis, in a heliothermic marine oyster lagoon in Norway.
(Journal article; Peer reviewed, 2022)Agapollen is a traditional heliothermic marine oyster lagoon in western Norway, representing the northernmost site of any Marteilia sp. protists detected in Europe. The semi-closed lagoon is a unique site to study the life ... -
Infection dynamics and tissue tropism of Parvicapsula pseudobranchicola (Myxozoa: Myxosporea) in farmed Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2018-01-06)Background The myxosporean parasite Parvicapsula pseudobranchicola commonly infects farmed Atlantic salmon in northern Norway. Heavy infections are associated with pseudobranch lesions, runting and mortality in the salmon ... -
Infectious salmon anaemia in Atlantic salmon, Salmo salar L. in Chile – transmission routes and prevention
(Doctoral thesis, 2014-08-29)Infectious salmon anaemia (ISA) virus causes a severe, commercially significant disease in all countries farming Atlantic salmon (Salmo salar). This thesis examines the ISA epizootic in Chile during 2007-09, known as the ... -
Infectious salmon anaemia virus (ISAV): Evolution, genotyping, reservoirs and transmission
(Doctoral thesis, 2012-06-01)The first officially registered outbreak of infectious salmon anaemia (ISA) started in Norway in November 1984 (Thorud and Djupvik, 1988). It was a chronically proceeding disease among Atlantic salmon (Salmo salar) parr ... -
Inferring Atlantic salmon post-smolt migration patterns using genetic assignment
(Peer reviewed; Journal article, 2019)Understanding migratory patterns is important for predicting and mitigating unwanted consequences of environmental change or anthropogenic challenges on vulnerable species. Wild Atlantic salmon undergo challenging migrations ... -
Inferring female extra-pair mating behaviour from observed patterns of extra-pair paternity with a process-based model
(Master thesis, 2014-10-01)There has been great focus on extra-pair paternity (EPP) in birds over the last decades. The knowledge gained has made researchers rethink certain notions about mating behaviour in birds. Initially it was believed that ... -
Inferring temperature adaptation from thermal performance curves of somatic growth rate: The importance of growth measurements and mortality
(Journal article; Peer reviewed, 2022)When comparing somatic growth thermal performance curves (TPCs), higher somatic growth across experimental temperatures is often observed for populations originating from colder environments. Such countergradient variation ... -
The influence of anaerobic muscle activity, maturation and season on the flesh quality of farmed turbot
(Peer reviewed; Journal article, 2010-04-26)In order to test seasonal, rearing, maturing and anaerobic muscle activity effect on the flesh quality of turbot (Scophthalmus maximus) a total of 80 farmed turbot from three different strains from reared under natural or ... -
The influence of CXCR4 on Maedi visna virus-induced syncytium formation
(Master thesis, 2001)Maedi visna virus (MVV) is a retrovirus that is member of the Lentivirus genus. MVV infects sheep and goats and causes progressive pneumonia or paralysis, leading to death. Since the discovery of the receptor for Human ... -
The influence of spatial scales on Red List composition: Forest species in Fennoscandia
