Interspecific differences in root foraging precision cannot be directly inferred from species' mycorrhizal status or fine root economics
(Journal article; Peer reviewed, 2023)Nutrient acquisition in plants can be represented by a suite of intercorrelated root traits such as root diameter, nitrogen content, root tissue density and specific root length. However, it is unclear how a plant's ability ... -
Intestinal function of the stomachless fish, ballan wrasse (Labrus bergylta)
(Peer reviewed; Journal article, 2019-03-26)Little is known about the digestion of nutrients in stomachless (agastric) fishes with short intestines, such as wrasse. This study describes the digestion, absorption and evacuation rates in ballan wrasse (Labrus bergylta) ... -
Intracellular trafficking of fatty acids in the fish intestinal epithelial cell line RTgutGC
(Journal article; Peer reviewed, 2022-09-29)The shift towards higher inclusion of vegetable oils (VOs) in aquafeeds has resulted in major changes in dietary fatty acid composition, especially increased amounts of monounsaturated fatty acids (MUFAs) and decreased ... -
Intramuscular vaccination of Atlantic lumpfish (Cyclopterus lumpus L.) induces inflammatory reactions and local immunoglobulin M production at the vaccine administration site
(Peer reviewed; Journal article, 2019)Atlantic lumpfish were vaccinated by intramuscular (im) or intraperitoneal (ip) injection with a multivalent oil‐based vaccine, while control fish were injected with phosphate‐buffered saline. Four lumpfish per group were ... -
Intraspecific trait variability is a key feature underlying high Arctic plant community resistance to climate warming
(Journal article; Peer reviewed, 2022)In the high Arctic, plant community species composition generally responds slowly to climate warming, whereas less is known about the community functional trait responses and consequences for ecosystem functioning. The ... -
Introducing the index-based ecological condition assessment framework (IBECA)
(Journal article; Peer reviewed, 2021)Sustainable nature management and ecosystem conservation depends critically on scientifically sound and stakeholder-relevant analytical frameworks for monitoring and assessing ecological condition. Several general frameworks ... -
Introgression of domesticated salmon changes life history and phenology of a wild salmon population
(Journal article; Peer reviewed, 2022)The release of domesticated conspecifics into the natural environment, whether deliberate or accidental, has the potential to alter the genetic integrity and evolutionary trajectory of wild populations. This widespread ... -
The invertebrate fauna of anthropogenic soils in the High-Arctic settlement of Barentsburg, Svalbard
(Peer reviewed; Journal article, 2013-05-17)The terrestrial environment of the High Arctic consists of a mosaic of habitat types. In addition to the natural habitat diversity, various human-influenced types may occur. For the resident invertebrate fauna, these ... -
Invest more and die faster: The life history of a parasite on intensive farms
(Peer reviewed; Journal article, 2017-10)Organisms are expected to respond to alterations in their survival by evolutionary changes in their life history traits. As agriculture and aquaculture have become increasingly intensive in the past decades, there has been ... -
Investigating elevational gradients of species richness in a Mediterranean plant hotspot using a published flora
(Journal article; Peer reviewed, 2021)The Apuan Alps are one of the most peculiar mountain chain in the Mediterranean, being very close to the coastline and reaching an elevation of almost 2000 m. Based on published flora, we investigated the distribution of ... -
Investigating the Disordered and Membrane-Active Peptide A-Cage-C Using Conformational Ensembles
(Journal article; Peer reviewed, 2021)The driving forces and conformational pathways leading to amphitropic protein-membrane binding and in some cases also to protein misfolding and aggregation is the subject of intensive research. In this study, a chimeric ... -
Investigating the frequency of triploid Atlantic salmon in wild Norwegian and Russian populations
(Peer reviewed; Journal article, 2018-10-03)Background Fish may display variations in ploidy, including three sets of chromosomes, known as triploidy. A recent study revealed a frequency of ~ 2% spontaneous (i.e., non-intentional) triploidy in domesticated Atlantic ... -
Investigating the metabolic, transcriptomic and DNA methylation signatures of high dietary arachidonic acid in zebrafish: Epigenetic and transcriptional effects in the next generation
(Doctoral thesis, 2018-03-14)Background. Nutrition is one of the important environmental determinants of individual health. Alteration in dietary omega-3 and omega-6 polyunsaturated fatty acid (n-3 and n-6 PUFA) profiles is known to affect the health ... -
Investigating the Versatility of a Flavin-containing Monooxygenase Engineered Towards Trimethylamine Conversion in Fish Protein Hydrolysate
(Master thesis, 2023-11-20)Byproducts from the seafood industry are rich in nutrients, such as peptides, which might be utilized to a greater extent in the food market. Peptides can be extracted from fish byproducts by enzymatic hydrolysis, but the ... -
An investigation into the parasitic barnacle, Anelasma squalicola; prevalence, infection behaviour and effects on its host, Etmopterus spinax, in Lusterfjord, Norway.
(Master thesis, 2016-06-27)Anelasma squalicola is a recently evolved parasite. Very little is known of its biology due to its normally low prevalence in deep sea lantern sharks (family: Etmopteridae), in which it is found embedded in the skin. A ... -
Investigation of crustaceans from shelf areas in the Gulf of Guinea, with special emphasis on Brachyura
(Master thesis, 2009)Crustacean abundance on continental shelves off Nigeria, Cameroon and Gabon in the Gulf of Guinea was investigated in this study. Quantitative data was sampled with a 0.1 m² Van Veen grab during a survey with RV Dr. Fridtjof ... -
