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
(Peer reviewed; Journal article, 2017)National Red Lists are widely used prioritizing tools for nature conservation. However, status and trends of species vary with scale, and accounting for a larger spatial scale may provide complementary perspectives for ... -
Influence of spawning stock size and environment on abundance and survival of juveniles in commercially important fish stocks in the Barents Sea
(Doctoral thesis, 2006-05-05)Stock-recruitment relationships are fundamental in management of fish stocks and fish recruitment is highly variable. Hence, a mechanistic understanding of the factors causing the variability in recruitment is a necessity ... -
Influence of suspended sediment front on nutrients and phytoplankton dynamics off the Changjiang Estuary: A FVCOM-ERSEM coupled model experiment
(Journal article; Peer reviewed, 2020)High-turbidity water is a common feature in the estuary and inner shelf. Sediment suspension functions as a modulator that directly influences the interactions among nutrients, phytoplankton and other related ecosystem ... -
The influence of vgll3 genotypes on sea age at maturity is altered in farmed mowi strain Atlantic salmon
(Peer reviewed; Journal article, 2019-05-06)Background: In Atlantic salmon in the wild, age at maturity is strongly influenced by the vgll3 locus. Under farming conditions, light, temperature and feeding regimes are known significantly advance or delay age at maturity. ... -
Influences of sea level changes and volcanic eruptions on Holocene vegetation in Tonga
(Journal article; Peer reviewed, 2023)Here, we investigate Mid- to Late-Holocene vegetation changes in low-lying coastal areas in Tonga and how changing sea levels and recurrent volcanic eruptions have influenced vegetation dynamics on four islands of the ... -
Injectable In Situ Crosslinking Hydrogel for Autologous Fat Grafting
