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 ... -
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, ... -

Immunrespons mot Pasteurella spp. hjå rognkjeks (Cyclopterus lumpus L.) og Atlantisk laks (Salmo salar L.)
(Master thesis, 2021-06-01)Dei siste åra har ein sett ei dramatisk auke i tilfelle pasteurellose i norsk oppdrett av rognkjeks (Cyclopterus lumpus L.) og Atlantisk laks (Salmo salar L.). Sjukdommen førar til redusert fiskevelferd og kan innebere høg ... -
Parasites Found in Pink Salmon (Oncorhynchus gorbuscha) Caught in the Feeding Areas in the Norwegian Sea
(Master thesis, 2021-06-01)The pink salmon (Oncorhynchus gorbuscha) is native to the North Pacific but has repeatedly been introduced to the North Atlantic by Russian researchers since 1956. This has resulted in the establishment of populations in ... -
Chitin synthases are critical for reproduction, molting, and digestion in the salmon louse (Lepeophtheirus salmonis)
(Journal article; Peer reviewed, 2021-01-13)Chitin synthase (CHS) is a large transmembrane enzyme that polymerizes Uridine diphosphate N-acetylglucosamine into chitin. The genomes of insects often encode two chitin synthases, CHS1 and CHS2. Their functional roles ... -
Chitin synthesis in the salmon louse Lepeophtheirus salmonis
(Doctoral thesis, 2021-06-18)The salmon louse Lepeophtheirus salmonis is a parasitic copepod that lives and feeds on Atlantic salmon (Salmo salmar). At present, this parasite is the number one threat to the Norwegian aquaculture. The density of salmons ... -
Archaeological bird remains from Norway as a means to identify long-term patterns in a Northern European avifauna
(Doctoral thesis, 2021-06-18)Birds are currently facing a biodiversity crisis. Seabirds, birds in agricultural landscapes, and montane birds are particularly vulnerable to extinction. Whilst their modern distributions are well studied, how past events ... -
Effect of tag weight on vertical behavior of Atlantic salmon (Salmo salar) smolts: an overlooked tag effect?

Caligus elongatus and other sea lice of the genus Caligus as parasites of farmed salmonids: A review
(Journal article; Peer reviewed, 2020)This review was prompted by reports of unusually large numbers of sea lice tentatively identified as Caligus elongatus infesting farmed salmon in northern Norway. Following a brief introduction to the sea lice problem in ... -
Ontogenetic movements of cod in Arctic fjords and the Barents Sea as revealed by otolith microchemistry
(Journal article; Peer reviewed, 2020-04-06)The distribution of Atlantic cod (Gadus morhua) in northern Norwegian waters is expanding eastward and northward in the Barents Sea and along western Svalbard. In the Arctic fjords of Svalbard, cod has become abundant, but ... -
Marine Plastics from Norwegian West Coast Carry Potentially Virulent Fish Pathogens and Opportunistic Human Pathogens Harboring New Variants of Antibiotic Resistance Genes
(Journal article; Peer reviewed, 2020)To our best knowledge this is the first study characterizing fish pathogens isolated from marine plastics from the West coast of Norway for their potential for pathogenicity using whole genome sequencing. Marine plastic ... -
Sequence-based enzyme discovery from marine microbial diversity : Multiple approaches for the heterologous expression of genes in Escherichia coli
(Doctoral thesis, 2021-06-09)The vast biodiversity of marine environments is increasingly being recognized as a source for new enzymes with value in both basic research and applications within biotechnology. In this project, the major aim was to ... -
Nutrient and chemical contaminant levels in five marine fish species from Angola—The EAF-Nansen programme
(Journal article; Peer reviewed, 2020)Fish is a rich source of several important nutrients and an important part of the otherwise plant-dominated diet present in Angola. However, fish may also be a source of contaminants. The aim of this study was to analyse ...
