Genetic population structure of minke whales Balaenoptera acutorostrata from Greenland, the North East Atlantic and the North Sea probably reflects different ecological regions
(Journal article; Peer reviewed, 2003-02-04)A genetic study to determine the population structure of minke whales Balaenoptera acutorostrata in Greenland, the Central and NE Atlantic and the North Sea was carried out on a sample of 306 individuals. Samples were ... -
Genetic population structure of the monogenean parasite Gyrodactylus thymalli and its host European grayling (Thymallus thymallus) in a large Norwegian lake
(Peer reviewed; Journal article, 2020)Understanding how populations are structured in space and time is a central question in evolutionary biology. Parasites and their hosts are assumed to evolve together, however, detailed understanding of mechanisms leading ... -
Genetic response to human-induced habitat changes in the marine environment: A century of evolution of European sprat in Landvikvannet, Norway
(Peer reviewed; Journal article, 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
(Journal article; Peer reviewed, 2016-02-09)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
(Peer reviewed; Journal article, 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 studies on eggs, larvae and 0-group of the Arctic cod stock
(PINRO-IMR Symposium, Conference object, 1984)Genetic analyses have been performed on samples of spawning cod (March) , a large number of eggs and yalk sac 1arvae (May, postlarvae (July) and O-group cod (August-September). The distribution of eggs and larvae at ... -
Genetic studies on released and recaptured cod in a fjord system
(ICES CM Documents;1992/G:65, Working paper, 1992)The study reported here is part of a more extensive investigation on the effects of mass rearing and release of 0-group cod in fjords and coastal areas in Norway. Each year since 1987 pond produced cod have been liberated ... -
Genetic study reveals local differentiation persisting in the face of high connectivity and a genomic inversion likely linked with sexual antagonism in a common marine fish
(Peer reviewed; Journal article, 2023)Sustainable harvest of wild populations requires knowledge of the underlying population structure. The focus of this study is on goldsinny wrasse (Ctenolabrus rupestris), a small marine fish inhabiting coastal waters of ... -
Genetic variation for upper thermal tolerance diminishes within and between populations with increasing acclimation temperature in Atlantic salmon
(Peer reviewed; Journal article, 2021)Populations may counteract lasting temperature changes or recurrent extremes through plasticity or adaptation. However, it remains underexplored how outbreeding, either naturally, unintentionally, or facilitated, may modify ... -
Genetics in the ocean’s twilight zone: Population structure of the glacier lanternfish across its distribution range
(Dataset, 2024)Dataset for "Genetics in the ocean’s twilight zone: Population structure of the glacier lanternfish across its distribution range", published in Evolutionary Applications, a Wiley journal The information deposited ... -
Genetics redraws pelagic biogeography of Calanus
(Peer reviewed; Journal article, 2017)Planktonic copepods of the genus Calanus play a central role in North Atlantic/Arctic marine food webs. Here, using molecular markers, we redrew the distributional ranges of Calanus species inhabiting the North Atlantic ... -

Genetiske analyser av aure i Gloppenelva
(Rapport fra havforskningen;2023 - 19, Research report, 2023)I Gloppenelva ble det åpnet en laksetrapp i Eidsfossen i 1972, men trappen ble stengt i 2014 etter store skader under en flomhendelse, og det er ikke avklart om trappen skal restaureres. Inntil 1972 var Eidsfossen ... -
