Genetic introgression of farmed salmon in native populations: quantifying the relative influence of population size and frequency of escapees
(Peer reviewed; Journal article, 2015-02-11)Farmed escapees may threaten the genetic integrity of native salmon populations through interbreeding. However, introgression requires survival until maturation, successful reproduction and successful early development. ... -
Genetic management of mixed-stock fisheries "real-time": The case of the largest remaining cod fishery operating in the Atlantic in 2007-2017
(Peer reviewed; Journal article, 2018-09)Fish stocks represent fundamental units in fisheries management, and their identification, especially in mixed-fisheries, represents one of the primary challenges to sustainable harvest. Here, we describe the first “real-time” ... -
Genetic ontogeny of pancreatic enzymes in Labrus bergylta larvae and the effect of feed type on enzyme activity and gene regulation
(Master thesis, 2012-06-01)In the later years increased interest in the use of Labrus bergylta (ballan wrasse) as a cleaner fish on Salmo salar (Atlantic salmon) has caused the emergence of commercial farming of L. bergylta. In order to cultivate ... -
Genetic origin and salinity history influence the reproductive success of Atlantic herring
(Peer reviewed; Journal article, 2018)Atlantic herring populations inhabit environments ranging in salinity from fully marine to nearly freshwater, but their relative reproductive success in these respective environments remains unclear. We conducted factorial ... -
Genetic response to human-induced habitat changes in the marine environment: A century of evolution of European sprat in Landvikvannet, Norway
(Journal article; Peer reviewed, 2021)Habitat changes represent one of the five most pervasive threats to biodiversity. However, anthropogenic activities also have the capacity to create novel niche spaces to which species respond differently. In 1880, one ... -
Genetic screening of farmed Atlantic salmon escapees demonstrates that triploid fish display reduced migration to freshwater
(Peer reviewed; Journal article, 2016-05)Each year, hundreds of thousands of farmed Atlantic salmon escape from fish farms into the wild. Some of these escapees enter freshwater, and manage to interbreed with native populations. To hinder further genetic introgression ... -
Genetic structure of Sufflogobius bibarbatus in the Benguela upwelling ecosystem using microsatellite markers
(Journal article; Peer reviewed, 2020)The bearded goby Sufflogobius bibarbatus is an abundant endemic small fish species on the continental shelf of the northern Benguela. The goby habitat is characterised by generally low bottom oxygen concentrations that ... -
Genetic variation of Piscine orthoreovirus and the presence of HSMI in farmed Atlantic salmon from Arctic Norway
(Master thesis, 2021-06-22)Piscine orthoreovirus-1 (PRV1) is ubiquitous throughout the world and can cause heart- and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon (Salmo salar). HSMI was first diagnosed in Norway in 1999. The virus ... -
Genetically modified plants as fish feed ingredients. Roundup Ready® soy, MON810 maize, Atlantic salmon, zebrafish
(Doctoral thesis, 2009-09-25)Commonly used plant ingredients in salmon feed such as soybeans and maize are increasingly grown as genetically modified (GM) varieties. The question arises whether these are equally nutritious and safe for the fish as ... -
Genetically similar temperate phages form coalitions with their shared host that lead to niche-specific fitness effects.
(Journal article; Peer reviewed, 2020-04-02)Temperate phages engage in long-term associations with their hosts that may lead to mutually beneficial interactions, of which the full extent is presently unknown. Here, we describe an environmentally relevant model system ... -
Genome and low-iron response of an oceanic diatom adapted to chronic iron limitation
(Peer reviewed; Journal article, 2012-07-26)Background: Biogeochemical elemental cycling is driven by primary production of biomass via phototrophic phytoplankton growth, with 40% of marine productivity being assigned to diatoms. Phytoplankton growth is widely limited ... -
Genome wide analysis reveals genetic divergence between Goldsinny wrasse populations
(Journal article; Peer reviewed, 2020)Background Marine fish populations are often characterized by high levels of gene flow and correspondingly low genetic divergence. This presents a challenge to define management units. Goldsinny wrasse (Ctenolabrus ... -
Genome- and transcriptomederived microsatellite loci in lumpfsh Cyclopterus lumpus: molecular tools for aquaculture, conservation and fsheries management
(Journal article; Peer reviewed, 2020)The lumpfish Cyclopterus lumpus is commercially exploited in numerous areas of its range in the North Atlantic Ocean, and is important in salmonid aquaculture as a biological agent for controlling sea lice. Despite the ... -
Genome-wide analysis of Atlantic salmon (Salmo salar) mucin genes and their role as biomarkers
(Peer reviewed; Journal article, 2017-10-08)The aim of this study was to identify potential mucin genes in the Atlantic salmon genome and evaluate tissue-specific distribution and transcriptional regulation in response to aquaculture- relevant stress conditions in ... -
Genome-wide analysis of the sox family in the calcareous sponge Sycon ciliatum: multiple genes with unique expression patterns
(Peer reviewed; Journal article, 2012-06-23)Background: Sox genes are HMG-domain containing transcription factors with important roles in developmental processes in animals; many of them appear to have conserved functions among eumetazoans. Demosponges have fewer ... -
Genome-wide DNA methylation profiling of non-small cell lung carcinomas
(Peer reviewed; Journal article, 2012-06-22)Background: Non-small cell lung carcinoma (NSCLC) is a complex malignancy that owing to its heterogeneity and poor prognosis poses many challenges to diagnosis, prognosis and patient treatment. DNA methylation is an important ... -
The genome-wide dynamics of the binding of Ldb1 complexes during erythroid differentiation
