Leads in Arctic pack ice enable early phytoplankton blooms below snow-covered sea ic
(Peer reviewed; Journal article, 2017) -
Marine fog inputs appear to increase methylmercury bioaccumulation in a coastal terrestrial food web
(Journal article; Peer reviewed, 2019)Coastal marine atmospheric fog has recently been implicated as a potential source of ocean-derived monomethylmercury (MMHg) to coastal terrestrial ecosystems through the process of sea-to-land advection of foggy air masses ... -
MicroRNAs in Daphnia magna identified and characterized by deep sequencing, genome mapping and manual curation
(Journal article; Peer reviewed, 2019)MicroRNAs (miRNAs) are small non-coding RNAs that function in RNA silencing and post-transcriptional regulation of gene expression in most organisms. The water flea, Daphnia magna is a key model to study phenotypic, ... -
New insights in oocyte dynamics shed light on the complexities associated with fish reproductive strategies
(Journal article; Peer reviewed, 2019)Information on temporal variations in stock reproductive potential (SRP) is essential in fisheries management. Despite this relevance, fundamental understanding of egg production variability remains largely unclear due to ... -
A non-lethal method for detection of Bonamia ostreae in flat oyster (Ostrea edulis) using environmental DNA
(Peer reviewed; Journal article, 2020)Surveillance and diagnosis of parasitic Bonamia ostreae infections in flat oysters (Ostrea edulis) are prerequisites for protection and management of wild populations. In addition, reliable and non-lethal detection methods ... -
Ocean sprawl facilitates dispersal and connectivity of protected species
(Journal article; Peer reviewed, 2018)Highly connected networks generally improve resilience in complex systems. We present a novel application of this paradigm and investigated the potential for anthropogenic structures in the ocean to enhance connectivity ... -
Overexpression of cyclooxygenase-2 in adipocytes reduces fat accumulation in inguinal white adipose tissue and hepatic steatosis in high-fat fed mice
(Journal article; Peer reviewed, 2019)Cyclooxygenases are known as important regulators of metabolism and immune processes via conversion of C20 fatty acids into various regulatory lipid mediators, and cyclooxygenase activity has been implicated in browning ... -
Parental micronutrient deficiency distorts liver DNA methylation and expression of lipid genes associated with a fatty-liver-like phenotype in offspring
(Journal article; Peer reviewed, 2018)Micronutrient status of parents can affect long term health of their progeny. Around 2 billion humans are affected by chronic micronutrient deficiency. In this study we use zebrafish as a model system to examine morphological, ... -
Potential changes in the connectivity of marine protected areas driven by extreme ocean warming
(Peer reviewed; Journal article, 2021)Projected future climate scenarios anticipate a warmer tropical ocean and changes in surface currents that will likely influence the survival of marine organisms and the connectivity of marine protected areas (MPAs) networks. ... -
Quantitative molecular detection of larval Atlantic herring (Clupea harengus) in stomach contents of Atlantic mackerel (Scomber scombrus) marks regions of predation pressure
(Peer reviewed; Journal article, 2021)Mortality rates in the early life-history stages of fishes are generally high yet identifying the causes remain unclear. Faltering recruitment rates of Atlantic herring (Clupea harengus) in the Norwegian Sea indicate a ... -
Recycling pathways in cold-water coral reefs: Use of dissolved organic matter and bacteria by key suspension feeding taxa
(Peer reviewed; Journal article, 2020)Cold-water coral (CWC) reefs are one of the most diverse and productive ecosystems in the deep sea. Especially in periods of seasonally-reduced phytodetritus food supply, their high productivity may depend on the recycling ... -
Rescue of germ cells in dnd crispant embryos opens the possibility to produce inherited sterility in Atlantic salmon
(Peer reviewed; Journal article, 2020)Genetic introgression of escaped farmed Atlantic salmon (Salmo salar) into wild populations is a major environmental concern for the salmon aquaculture industry. Using sterile fish in commercial aquaculture operations is, ... -
Salmon lice in the Pacific Ocean show evidence of evolved resistance to parasiticide treatment
(Peer reviewed; Journal article, 2022)Parasitic salmon lice (Lepeophtheirus salmonis) threaten the economic and ecological sustainability of salmon farming, and their evolved resistance to treatment with emamectin benzoate (EMB) has been a major problem for ... -
The salmon louse genome may be much larger than sequencing suggests.
(Peer reviewed; Journal article, 2022)The genome size of organisms impacts their evolution and biology and is often assumed to be characteristic of a species. Here we present the first published estimates of genome size of the ecologically and economically ... -
Sea ice variability and maritime activity around Svalbard in the period 2012–2019
(Peer reviewed; Journal article, 2020)Climate change is strongly impacting the Arctic environment, leading to rapid sea ice loss. In some sectors, the retreating ice edge is perceived as an opportunity to expand and develop economic activities. Previous studies ... -
Sex steroid production associated with puberty is absent in germ cellfree salmon
(Peer reviewed; Journal article, 2017) -
Substantial blue carbon in overlooked Australian kelp forests
(Peer reviewed; Journal article, 2020)Recognition of the potential for vegetated coastal ecosystems to store and sequester carbon has led to their increasing inclusion into global carbon budgets and carbon offset schemes. However, kelp forests have been ... -
Technological creep masks continued decline in a lobster (Homarus gammarus) fishery over a century
(Peer reviewed; Journal article, 2022)Fishery-dependent data are frequently used to inform management decisions. However, inferences about stock development based on commercial data such as Catch-Per-Unit-Effort (CPUE) can be severely biased due to a phenomenon ... -
Temporal patterns in the soundscape of a Norwegian gateway to the Arctic
(Peer reviewed; Journal article, 2022)As an Arctic gateway, the Norwegian Sea sustains a rich diversity of seasonal and resident species of soniferous animals, vulnerable to the effects of climate change and anthropogenic activities. We show the occurrence of ... -
The Atlantic salmon (Salmo salar) antimicrobial peptide cathelicidin-2 is a molecular host-associated cue for the salmon louse (Lepeophtheirus salmonis)
(Journal article; Peer reviewed, 2018)Chemical signals are a key element of host-parasite interactions. In marine ecosystems, obligate ectoparasites, such as sea lice, use chemical cues and other sensory signals to increase the probability of encountering a ...
