Evaluering av ulike agn til snøkrabbefiske i Barentshavet
(Peer reviewed; Journal article, 2021)Akkar og sild er de vanligste agnene som blir brukt under snøkrabbefiske i Barentshavet i dag. Ut fra økonomiske og etiske betraktninger er det viktig å erstatte dagens agn med alternative restråstoffkilder som har liten ... -
Evidence for light-controlled migration amplitude of a sound scattering layer in the Norwegian Sea
(Journal article; Peer reviewed, 2016-06-09)The oceanic sound scattering layer (SL) is an ubiquitous acoustic signature of mesopelagic fishes and invertebrates that are important food sources for the oceanic macrofauna and players in the biological carbon pump. We ... -
Evidence of diel vertical migration of mesopelagic sound-scattering organisms in the Arctic
(Peer reviewed; Journal article, 2017) -
Evidence of energy and nutrient transfer from invasive pink salmon (Oncorhynchus gorbuscha) spawners to juvenile Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) in northern Norway
(Peer reviewed; Journal article, 2020)Recent large influxes of non-native Pacific pink salmon (Oncorhynchus gorbuscha) to North European rivers have raised concern over their potential negative impacts on native salmonids and recipient ecosystems. The eggs and ... -
Evidence of hybridization between genetically distinct Baltic cod stocks during peak population abundance(s)
(Peer reviewed; Journal article, 2023)Range expansions can lead to increased contact of divergent populations, thus increasing the potential of hybridization events. Whether viable hybrids are produced will most likely depend on the level of genomic divergence ... -

Evidence of separate influence of moon and sun on light synchronization of mussel's daily rhythm during the polar night
(Peer reviewed; Journal article, 2023)Marine organisms living at high latitudes are faced with a light climate that undergoes drastic annual changes, especially during the polar night (PN) when the sun remains below the horizon for months. This raises the ... -
Evidence of temperature control on mesopelagic fish and zooplankton communities at high latitudes
(Peer reviewed; Journal article, 2022)Across temperate and equatorial oceans, a diverse community of fish and zooplankton occupies the mesopelagic zone, where they are detectable as sound-scattering layers. At high latitudes, extreme day-night light cycles may ... -
Evolution of age and length at maturation of Alaskan salmon under size-selective harvest
(Journal article; Peer reviewed, 2013-11-12)Spatial and temporal trends and variation in life-history traits, including age and length at maturation, can be influenced by environmental and anthropogenic processes, including size-selective exploitation. Spawning ... -
Evolution of reproduction periods in seasonal environments
(Peer reviewed; Journal article, 2020)Many species are subject to seasonal cycles in resource availability, affecting the timing of their reproduction. Using a stage-structured consumer-resource model in which juvenile development and maturation are resource ... -
Evolution of the immune system influences speciation rates in teleost fishes
(Journal article; Peer reviewed, 2016)Teleost fishes constitute the most species-rich vertebrate clade and exhibit extensive genetic and phenotypic variation, including diverse immune defense strategies. The genomic basis of a particularly aberrant strategy ... -
Evolutionary drivers of kype size in atlantic salmon (salmo salar): domestication, age and genetics
(Journal article; Peer reviewed, 2019)The diversity of reproduction and associated mating patterns in Atlantic salmon (Salmo salar) has long captivated evolutionary biologists. Salmo salar exhibit strategies involving migration, bold mating behaviours and ... -
Evolutionary effects of fishing gear on foraging behavior and life-history traits
(Journal article; Peer reviewed, 2018)Fishing gears are designed to exploit the natural behaviors of fish, and the concern that fishing may cause evolution of behavioral traits has been receiving increasing attention. The first intuitive expectation is that ... -
An evolutionary explanation of female-biased sexual size dimorphism in North Sea plaice, Pleuronectes platessa L.
(Peer reviewed; Journal article, 2023)Sexual size dimorphism (SSD) is caused by differences in selection pressures and life-history trade-offs faced by males and females. Proximate causes of SSD may involve sex-specific mortality, energy acquisition, and energy ... -
Evolutionary history and seascape genomics of Harbour porpoises (Phocoena phocoena) across environmental gradients in the North Atlantic and adjacent waters
(Peer reviewed; Journal article, 2023)The Harbour porpoise (Phocoena phocoena) is a highly mobile cetacean species primarily occurring in coastal and shelf waters across the Northern hemisphere. It inhabits heterogeneous seascapes broadly varying in salinity ... -
Evolutionary predictions for a parasite metapopulation: Modelling salmon louse resistance to pest controls in aquaculture
(Peer reviewed; Journal article, 2023)Pests often evolve resistance to pest controls used in agriculture and aquaculture. The rate of pest adaptation is influenced by the type of control, the selective pressure it imposes, and the gene flow between farms. By ... -
Examination of Sea Ice Cover in Norwegian Fjords
(Lecture, 2017)Presented are two steps being taken to examine sea ice coverage in Norwegian fjords as part of a larger study to improve our understanding of ice formation and breakup processes in these regions and implications for oil ... -
The exorhodopsin and melanopsin systems in the pineal complex and brain at early developmental stages of Atlantic halibut (Hippoglossus hippoglossus)
(Peer reviewed; Journal article, 2014)The complexity of the nonvisual photoreception systems in teleosts has just started to be appreciated, with colocalization of multiple photoreceptor types with unresolved functions. Here we describe an intricate expression ... -
An Expanded Gene Catalog of Mouse Gut Metagenomes
(Peer reviewed; Journal article, 2021)High-quality and comprehensive reference gene catalogs are essential for metagenomic research. The rather low diversity of samples used to construct existing catalogs of the mouse gut metagenome limits the numbers of ... -
Expected Climate Change in the High Arctic—Good or Bad for Arctic Charr?
(Peer reviewed; Journal article, 2023)Lakes in the High Arctic are characterized by their low water temperature, long-term ice cover, low levels of nutrients, and low biodiversity. These conditions mean that minor climatic changes may be of great importance ...
