Freshwater small pelagic fish and fisheries in the main African great lakes and reservoirs in relation to food security and nutrition
(Research report, 2019)This paper reviews the status and importance of the freshwater small pelagic fish and fisheries for sustainable healthy livelihoods in Africa. The lack of recognition of the importance of small pelagic fish for the sustenance, ... -
From a crisis to an opportunity: Eight insights for doing science in the COVID‐19 era and beyond
(Journal article; Peer reviewed, 2020)The COVID-19 crisis has forced researchers in Ecology to change the way we work almost overnight. Nonetheless, the pandemic has provided us with several novel components for a new way of conducting science. In this perspective ... -
From complex to simple: Myogenesis in an aplacophoran mollusk reveals key traits in aculiferan evolution
(Peer reviewed; Journal article, 2015-09-18)Background: Recent studies suggest a bifurcation at the base of Mollusca, resulting in the primarily single-shelled Conchifera (Bivalvia, Gastropoda, Scaphopoda, Monoplacophora, Cephalopoda) and the spicule-bearing Aculifera ... -
From notochord to vertebral column: studies on Atlantic salmon (Salmo salar L.)
(Doctoral thesis, 2007-05-11)The notochord initially form a single-cell file stage of chordoblasts covered by a three layered sheath comprising a basal lamina, a main collagenous layer and an external elastic membrane. During early ontogeny, the ... -
From pollen percentage to vegetation cover – evaluation ofthe Landscape Reconstruction Algorithm in western Norway
(Peer reviewed; Journal article, 2015-06-23)The Landscape Reconstruction Algorithm (LRA) with the two models REVEALS and LOVE is developed to transform pollen percentage data to vegetation cover. This paper presents the first study to evaluate LRA in a region with ... -
From self-interest to cooperation: extra-pair mating as a driver of relaxed territorial aggression in social neighbourhoods
(Journal article; Peer reviewed, 2023)In socially monogamous bird species, males and females tailor their reproductive strategies to that of the other. Interactions are complex, and have elements of both conflict and cooperation. Breeding process is further ... -
From sensing to emergent adaptations: Modelling the proximate architecture for decision-making
(Peer reviewed; Journal article, 2016-04)During the past 50 years, evolutionary theory for animal behaviour has branched into different methodological frameworks focussing on age-, state-, density-, and frequency-dependent processes. These approaches have led to ... -
From the fjords to the rivers: Evaluating the spatial distribution of escaped farmed salmon to inform ecologically relevant management strategies
(Doctoral thesis, 2020-05-08)Over the last 40 years, the relatively fast expansion of Atlantic salmon aquaculture has created new obstacles for the persistence of wild Atlantic salmon stocks where the two overlap. Now, the greatest threat to existing ... -
From tides to nucleotides: Genomic signatures of adaptation to environmental heterogeneity in barnacles
(Journal article; Peer reviewed, 2021)The northern acorn barnacle (Semibalanus balanoides) is a robust system to study the genetic basis of adaptations to highly heterogeneous environments. Adult barnacles may be exposed to highly dissimilar levels of thermal ... -
The FTZ-F1 gene encodes two functionally distinct nuclear receptor isoforms in the ectoparasitic copepod salmon louse (Lepeophtheirus salmonis)
(Journal article; Peer reviewed, 2021)The salmon louse, Lepeophtheirus salmonis, is an ectoparasitic crustacean that annually inflicts substantial losses to the aquaculture industry in the northern hemisphere and poses a threat to the wild populations of ... -
Functional analysis of metagenomes and metatranscriptomes using SEED and KEGG
(Peer reviewed; Journal article, 2011-02-15)Background: Metagenomics is the study of microbial organisms using sequencing applied directly to environmental samples. Technological advances in next-generation sequencing methods are fueling a rapid increase in the ... -
Functional analysis of the nonvisual opsins melanopsin and vertebrate ancient opsin (VA opsin) in Atlantic salmon (Salmo salar)
(Master thesis, 2017-06-15)The role of nonvisual photoreceptors is yet to be elucidated regarding the link to biological function. This study aims to characterise the expression pattern of melanopsin and vertebrate ancient opsin during early ... -
Functional analysis of tilS homologues in Bacteria and Archaea
(Master thesis, 2005-09-09)Out of all of the microorganisms sequenced so far about one third of the genes have unknown function. Several studies have shown that information on evolutionary relationships between unknown genes can aid in the prediction ... -
Functional characterisation of polybasic motifs in the nucleolar PtdIns(3,4,5)P3- interacting proteins proliferation-associated protein 2G4 and poly(ADP-ribose) polymerase 1
(Doctoral thesis, 2023-06-13)Fosfoinositid 3-kinase (PI3K)-signalveien er viktig for flere cellulære prosesser, inklusiv celleoverlevelse, proliferasjon og proteinsyntese. Den er godt beskrevet i cytoplasmaet. I tillegg kan fosfatidylinositol ... -
Functional characterisation of three human nicotinamide mononucleotide adenylyltransferases
(Doctoral thesis, 2008-08-25)Nicotinamide adenine dinucleotide, NAD, is an essential redox factor in many, primarily catabolic, hydrogen transfer reactions. While the redox reactions are not accompanied by a net loss of the pyridine nucleotides, NAD+ ... -
Functional characterization of Atlantic salmon (Salmo salar L.) PepT2 transporters
(Journal article; Peer reviewed, 2022)The high-affinity/low-capacity system Slc15a2 (PepT2) is responsible for the reuptake of di/tripeptides from the renal proximal tubule, but it also operates in many other tissues and organs. Information regarding PepT2 in ... -
Functional characterization of Carboxyl Ester Lipase variants causing diabetes and exocrine dysfunction
