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 ... -
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 ... -
Inspection of a novel object by wild and laboratory Zebrafish (Danio rerio H.) in the presence and absence of alarm substance
(Master thesis, 2008)Zebrafish (Danio rerio) is a small Ostariophysian cyprinid fish with no special body armour, which makes them vulnerable to predation. They possess chemical alarm pheromones (Schreckstoff) in the epidermal club cells, ... -
Instar growth and Development of Lepeophtheirus salmonis Copepodids.
(Master thesis, 2009-05-07)Salmon louse Lepeophtheirus salmonis, (Krøyer, 1837) is a caligid parasite, responsible for major economical loss and welfare issues in Norwegian marine culture of salmonid species. Infections are mainly controlled with ... -
Instar growth and molt increments in Lepeophtheirus salmonis (Copepoda: Caligidae) chalimus larvae
(Peer reviewed; Journal article, 2015-02)The salmon louse (Lepeophtheirus salmonis) is an ectoparasitic copepod causing severe problems to the fish farming industry and to wild salmonids. Morphologically, all stages in the life cycle of L. salmonis have been ... -
Integrating human dimensions in decadal-scale prediction for marine social–ecological systems: lighting the grey zone
(Journal article; Peer reviewed, 2023)The dynamics of marine systems at decadal scales are notoriously hard to predict—hence references to this timescale as the “grey zone” for ocean prediction. Nevertheless, decadal-scale prediction is a rapidly developing ... -
Integration matters: Combining socio-cultural and biophysical methods for mapping ecosystem service bundles
(Journal article; Peer reviewed, 2023)Ecosystem services (ESs) play an important role in sustainable landscape management. People value ESs in diverse ways encompassing social and ecological domains and we need to bring these different values together. We used ... -
Integrative omics-analysis of lipid metabolism regulation by peroxisome proliferator-activated receptor a and b agonists in male Atlantic cod
(Journal article; Peer reviewed, 2023-03-22)Lipid metabolism is essential in maintaining energy homeostasis in multicellular organisms. In vertebrates, the peroxisome proliferator-activated receptors (PPARs, NR1C) regulate the expression of many genes involved in ... -
Intensive Farming: Evolutionary Implications for Parasites and Pathogens
(Peer reviewed; Journal article, 2010)An increasing number of scientists have recently raised concerns about the threat posed by human intervention on the evolution of parasites and disease agents. New parasites (including pathogens) keep emerging and parasites ... -
