(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Mediaeval walrus hunting in Iceland and Greenland—driven by Western European demand for ivory and walrus hide ropes—has been identified as an important pre-modern example of ecological globalization. By contrast, the main ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Plants must adapt with increasing speed to global warming to maintain their fitness. One rapid adaptation mechanism is epigenetic memory, which may provide organisms sufficient time to adapt to climate change. We studied ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Synopsis Temperature profoundly affects ectotherm physiology. Although differential thermal responses influence fitness, thus driving population dynamics and species distributions, our understanding of the molecular ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)The acquisition of tolerance to an environmental stressor can result in organisms displaying slower growth after stress release. While well-grounded in the theory, empirical evidence of the trade-off between stress tolerance ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)In the last decades, limnic water bodies in the Northern hemisphere have experienced a noticeable browning, i.e., increasing levels of dissolved organic matter (DOM). While the effects on primary producers is usually ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Voluntary contributions to public goods are vulnerable to free riding. A potential solution is the implementation of a costly institutional arrangement that deters free riding behavior. In this paper, we analyze to what ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract It is well known that weak hydraulic jumps and bores develop a growing number of surface oscillations behind the bore front. Defining the bore strength as the ratio of the head of the undular bore to the undisturbed ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Animals exhibit a diversity of movement tactics [1]. Tracking resources that change across space and time is predicted to be a fundamental driver of animal movement [2]. For example, some migratory ungulates (i.e., hooved ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract Tight control of gene expression networks required for adipose tissue formation and plasticity is essential for adaptation to energy needs and environmental cues. However, the mechanisms that orchestrate ...
-
(Master thesis / Masteroppgave, 2021)We exposed the microbiome derived from two species of cod, from the outer and inner Oslo fjord to extracts derived from car tire rubber. To determine toxicity we look at growth rate and bacterial diversity as endpoints. ...
-
(Master thesis / Masteroppgave, 2013)The WEE1-inhibitor MK-1775 is currently in clinical trials as an anti-cancer drug. In response to DNA damage, human cells activate cell cycle checkpoints to temporarily halt cell cycle progression, and this helps facilitating ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Little is known about the evolution of cold tolerance in polar plant species and how they differ from temperate relatives. To gain insight into their biology and the evolution of cold tolerance, we compared the molecular ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Examining the supposition that local-scale competition drives macroevolutionary patterns has become a familiar goal in fossil biodiversity studies. However, it is an elusive goal, hampered by inadequate confirmation of ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)In this study, we analyzed long‐term trends in calcium (Ca) concentrations for 70 Norwegian lakes spanning a broad geographical range and for a wide range of ambient drivers. A striking decline in Ca concentrations was ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Genetic assimilation emerges from selection on phenotypic plasticity. Yet, commonly used quantitative genetics models of linear reaction norms considering intercept and slope as traits do not mimic the full process of ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract Human activity and associated landscape modifications alter the movements of animals with consequences for populations and ecosystems worldwide. Species performing long‐distance movements are thought to be ...
-
(Master thesis / Masteroppgave, 2019)Reproductive output in alpine plants depend on abiotic and biotic factors. Alpine topography creates microhabitats for plants, with abiotic factors, like temperature, snow cover and soil moisture playing an important role ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Teleost fishes comprise more than half of all vertebrate species, yet genomic data are only available for 0.2% of their diversity. Here, we present whole genome sequencing data for 66 new species of teleosts, vastly expanding ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Atlantic cod has lost the Major Histocompatibility complex class II pathway – central to pathogen presentation, humoral response and immunity. Here, we investigate the immunological response of Atlantic cod subsequent to ...
