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
(Journal article; Peer reviewed, 2023)Autologous fat grafting is hampered by unpredictable outcomes due to high tissue resorption. Hydrogels based on enzymatically pretreated tunicate nanocellulose (ETC) and alginate (ALG) are biocompatible, safe, and present ... -
Injury-induced MAPK activation triggers body axis formation in Hydra by default Wnt signaling
(Journal article; Peer reviewed, 2022)Hydra’s almost unlimited regenerative potential is based on Wnt signaling, but so far it is unknown how the injury stimulus is transmitted to discrete patterning fates in head and foot regenerates. We previously identified ... -
Innate immune mechanisms in invertebrates: Insights into the Toll pathway, the Imd pathway, and the complement system
(Doctoral thesis, 2021-06-25)The innate immune system is the first line of defense against pathogens. This system is equipped with receptors, named Pattern Recognition Receptors (PRRs), that recognize a broad set of molecules present in pathogens, ... -
Innate immune responses of lumpfish (Cyclopterus lumpus) : Transcriptome analysis and characterization of pro-inflammatory cytokines
(Doctoral thesis, 2020-03-05)In recent years, lumpfish and different species of wrasse are used as cleaner fishes for removal of sea lice from farmed Atlantic salmon in Europe and Canada. The production is successful, but there are challenges with ... -
Innovating carbon-capture biotechnologies through ecosystem-inspired solutions
(Journal article; Peer reviewed, 2021)Rising atmospheric carbon concentrations affect global health, the economy, and overall quality of life. We are fast approaching climate tipping points that must be addressed, not only by reducing emissions but also through ... -
An innovative approach to using an intensive field course to build scientific and professional skills
(Journal article; Peer reviewed, 2022)This paper reports on the design and evaluation of Field Studies in Functional Ecology (FSFE), a two-week intensive residential field course that enables students to master core content in functional ecology alongside ... -
Input of easily available organic C and N stimulates microbial decomposition of soil organic matter in arctic permafrost soil
(Peer reviewed; Journal article, 2014-08)Rising temperatures in the Arctic can affect soil organic matter (SOM) decomposition directly and indirectly, by increasing plant primary production and thus the allocation of plant-derived organic compounds into the soil. ... -
Insect glycerol transporters evolved by functional co-option and gene replacement
(Peer reviewed; Journal article, 2015-07-17)Transmembrane glycerol transport is typically facilitated by aquaglyceroporins in Prokaryota and Eukaryota. In holometabolan insects however, aquaglyceroporins are absent, yet several species possess polyol permeable ... -
Insects reared on seaweed as novel feed ingredients for Atlantic salmon (Salmo salar) : Investigating the transfer of essential nutrients and undesirable substances along the seaweed-insect-fish food chain
(Doctoral thesis, 2020-12-09)Traditionally, major sources of protein and lipid in aquaculture fish feeds have been fish meal and fish oil. However, fish stocks used for fish meal and fish oil production are fully exploited, therefore prices of these ... -
Insights into NAD homeostasis in the compartmentalized cell
(Doctoral thesis, 2015-08-24)The compartmentalized nature of eukaryotic cells requires the distribution of enzymes, metabolites, and cofactors among the organelles. This includes nicotinamide adenine dinucleotide (NAD), an essential coenzyme, precursor, ... -
Insights into the genetic diversity, antibiotic resistance and pathogenic potential of Klebsiella pneumoniae from the Norwegian marine environment using whole-genome analysis
(Journal article; Peer reviewed, 2022)Klebsiella pneumoniae (Kp) can cause hospital- and community acquired infections. Although, Kp is widespread in the environment, very little is known about the genetic diversity and pathogenicity of Kp from the marine ... -
