Bioactive Metabolites of Marine Origin Have Unusual Effects on Model Membrane Systems
(Journal article; Peer reviewed, 2020)Marine sponges and soft corals have yielded novel compounds with antineoplastic and antimicrobial activities. Their mechanisms of action are poorly understood, and in most cases, little relevant experimental evidence is ... -
Lipid transporters and receptor in salmon louse (Lepeophtheirus salmonis) : Effect of RNAi Knockdown on oogenesis, embryonal development and larval maturation
(Doctoral thesis, 2021-04-23)The salmon louse, Lepeophtheirus salmonis, is a marine ectoparasite of salmonids in the Northern Hemisphere. At present, salmon louse infestation is considered as one of the biggest challenges in the salmon farming industry, ... -
Genome- and transcriptomederived microsatellite loci in lumpfsh Cyclopterus lumpus: molecular tools for aquaculture, conservation and fsheries management
(Journal article; Peer reviewed, 2020)The lumpfish Cyclopterus lumpus is commercially exploited in numerous areas of its range in the North Atlantic Ocean, and is important in salmonid aquaculture as a biological agent for controlling sea lice. Despite the ... -
Molecular systematics of the long-snouted deep water dogfish (Centrophoridae, Deania) with implications for identification, taxonomy and conservation.
(Journal article; Peer reviewed, 2021-01-20)According to the most recent taxonomical revision, the deep-sea dogfish genus Deania encompasses four species. Three of them, D. calcea, D. profundorum, and D. hystricosa, occur in the North Atlantic. Whilst D. profundorum ... -
Identification of critical enzymes in the salmon louse chitin synthesis pathway as revealed by RNA interference-mediated abrogation of infectivity
(Journal article; Peer reviewed, 2020)Treatment of infestation by the ectoparasite Lepeophtheirus salmonis relies on a small number of chemotherapeutant treatments that currently meet with limited success. Drugs targeting chitin synthesis have been largely ... -
Evolution of vegetation and climate variability on the Tibetan Plateau over the past 1.74 million years
(Journal article; Peer reviewed, 2020)The Tibetan Plateau exerts a major influence on Asian climate, but its long-term environmental history remains largely unknown. We present a detailed record of vegetation and climate changes over the past 1.74 million years ... -
Changes in histidine metabolism through smoltification and effect on cataract development in Atlantic Salmon (Salmo salar L.)
(Master thesis, 2021-01-20)Cataract is the collective definition of any light scattering opacities of the eye. Cataractogenesis is caused when there is a noticeable irregular light scattering because there has been a change in the tridimensional ... -
Salmon lice survive the straight shooter: A commercial scale sea cage trial of laser delousing
(Journal article; Peer reviewed, 2020)Ectoparasitic salmon louse (Lepeophtheirus salmonis) infestations are costly for Atlantic salmon (Salmo salar) farmers in Norway. As a result, there is a strong desire for solutions to prevent and control infestations, and ... -
Reflections on the Use of Ecological Attributes and Traits in Quaternary Botany
(Journal article; Peer reviewed, 2020)There has been an upsurge of interest and research activity in trait-based approaches in ecology, biogeography, and macroecology. I discuss if this upsurge has impacted Quaternary botany (the study of plant remains preserved ... -
Snapshot isolation and isolation history challenge the analogy between mountains and islands used to understand endemism
(Journal article; Peer reviewed, 2020)Aim Mountains and islands are both well known for their high endemism. To explain this similarity, parallels have been drawn between the insularity of “true islands” (land surrounded by water) and the isolation of habitats ... -
The impact of anti-sea lice pesticides, azamethiphos and deltamethrin, on European lobster (Homarus gammarus) larvae in the Norwegian marine environment
(Journal article; Peer reviewed, 2020)Anti-sea lice pesticides, used in the salmonid aquaculture industry, are a growing environmental concern due to their potential to adversely affect non-target crustaceans. Azamethiphos and deltamethrin are two bath treatment ... -
Changes in Sea-Ice Protist Diversity With Declining Sea Ice in the Arctic Ocean From the 1980s to 2010s
(Journal article; Peer reviewed, 2020)The large declines in Arctic sea-ice age and extent over the last decades could have altered the diversity of sea-ice associated unicellular eukaryotes (referred to as sea-ice protists). A time series from the Russian ... -
The Arabidopsis (ASHH2) CW domain binds monomethylated K4 of the histone H3 tail through conformational selection
(Journal article; Peer reviewed, 2020)Chromatin post‐translational modifications are thought to be important for epigenetic effects on gene expression. Methylation of histone N‐terminal tail lysine residues constitutes one of many such modifications, executed ... -
Comparison of Otolith Microstructure of Herring Larvae and Sibling Adults Reared Under Identical Early Life Conditions
(Journal article; Peer reviewed, 2020-07-03)Atlantic herring (Clupea harengus) is a euryhaline species, occupying fully marine habitats (35 psu) in the North Atlantic, as well as brackish waters (<20 psu) such as in the adjacent Baltic Sea. We co-reared Atlantic ... -
Gyrodactylus triglopsi n. sp. (Monogenea: Gyrodactylidae) from the Gills of Triglops nybelini Jensen, 1944 (Teleostei: Cottidae) in the Barents Sea
(Journal article; Peer reviewed, 2020-04-28)Introduction Monogeneans of the genus Gyrodactylus were found on the gills of specimens of the bigeye sculpin Triglops nybelini Jensen, 1944 caught by trawl in the Barents Sea in January–February 2016. Methods Morphological ... -
Relative transcript quantification by Quantitative PCR: Roughly right or precisely wrong?
(Journal article; Peer reviewed, 2005-04-26)Background When estimating relative transcript abundances by quantitative real-time PCR (Q-PCR) we found that the results can vary dramatically depending on the method chosen for data analysis. Results Analyses of ... -
Life histories determine divergent population trends for fishes under climate warming
(Journal article; Peer reviewed, 2020-08-14)Most marine fish species express life-history changes across temperature gradients, such as faster growth, earlier maturation, and higher mortality at higher temperature. However, such climate-driven effects on life histories ... -
Planctomycetes as a Vital Constituent of the Microbial Communities Inhabiting Different Layers of the Meromictic Lake Sælenvannet (Norway)
(Journal article; Peer reviewed, 2020)Meromictic lakes are permanently stratified lakes that display steep gradients in salinity, oxygen and sulphur compounds tightly linked to bacterial community structure and diversity. Lake Sælenvannet is a meromictic lake ... -
The effect of temperature on ability of Lepeophtheirus salmonis to infect and persist on Atlantic salmon
