(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Climate change-driven increases in air and sea temperatures are rapidly thawing the Arctic cryosphere with potential for remobilization and accumulation of legacy persistent organic pollutants (POPs) in adjacent coastal ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)Abstract Herbivorous rodents in boreal, alpine and arctic ecosystems are renowned for their multi‐annual population cycles. Researchers have hypothesised that these cycles may result from herbivore–plant interactions in ...

"Islands of divergence" in the Atlantic cod genome represent polymorphic chromosomal rearrangements (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)In several species genetic differentiation across environmental gradients or between geographically separate populations has been reported to center at “genomic islands of divergence,” resulting in heterogeneous differentiation ...

Isotopic niche differs between seal and fish-eating killer whales (Orcinus orca) in northern Norway (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Ecological diversity has been reported for killer whales (Orcinus orca) throughout the North Atlantic but patterns of prey specialization have remained poorly understood. We quantify interindividual dietary variations in ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)During the last decade, methods based on high-throughput sequencing such as DNA metabarcoding have opened up for a range of new questions in animal dietary studies. One of the major advantages of dietary metabarcoding ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)We tested the hypothesis that the coronate jellyfish Periphylla periphylla distributes vertically according to a preferential range of absolute light intensities. The study was carried out in Lurefjorden, Norway, a fjord ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The discovery of Ice Ages is one of the most revolutionary advances made in the Earth sciences. In 1824 Danish‐Norwegian geoscientist Jens Esmark published a paper stating that there was indisputable evidence that Norway ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)In 2010 we rediscovered the complete set of meteorological observation protocols made by Jens Esmark (1762–1839) during his years of residence in the Norwegian capital of Oslo (then Christiania). From 1 January 1816 to 25 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract As the excitation–contraction coupling is inseparable during voluntary exercise, the relative contribution of the mechanical and neural input on hypertrophy-related molecular signalling is still poorly understood. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Aquatic plant nutrient concentrations provide important information to characterise their role in nutrient retention and turnover in aquatic ecosystems. While large standing biomass of aquatic plants is typically found in ...
-
(Master thesis / Masteroppgave, 2024)Ratio ble satt til 76% rødalger, 17% brunalger og 7% grønnalger. 86 antall arter alger ble registrert. Stilklengde, laminalengde og total lengde for stortare var lenger om våren. På eksponerte områder ble det funnet flere ...

-
(Master thesis / Masteroppgave, 2020)Økt menneskelig påvirkning på kystområder kan føre til at endringer i fysiske og biologiske miljøfaktorer skjer raskt. Slike endringer vil være utfordrende for en rekke arter tilpasset spesifikke økosystem. Marine ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)In animals with long generation times, evolution of physiological and morphological traits may not be fast enough to keep up with rapid climate warming, but thermoregulatory behaviour can possibly serve as an important ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Mechanisms have evolved that allow cells to detect signals and generate an appropriate response. The accuracy of these responses relies on the ability of cells to discriminate between signal and noise. How cells filter ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)This study investigates survival and abundance of killer whales (Orcinus orca) in Norway in 1988–2019 using capture–recapture models of photo-identification data. We merged two datasets collected in a restricted fjord ...
-
(Master thesis / Masteroppgave, 2023)The Hardangerfjord has a high density of harbour porpoises, making it stand out among Norwegian fjords as a particularly important habitat. A new predator-prey relationship emerged in 2017, with killer whales entering the ...
-
(Master thesis / Masteroppgave, 2014)A first survey of southern Norway to sample and examine Norwegian Kinorhyncha biodiversity. Also beginning to establish a sequence database for future use in Kinorhyncha barcoding.
