Polycyclic aromatic hydrocarbons (PAHs), oxy- and nitro-PAHs in ambient air of the Arctic town Longyearbyen, Svalbard
(Peer reviewed; Journal article, 2020)Polycyclic aromatic hydrocarbons (PAHs) are not declining in Arctic air despite reductions in their global emissions. In Svalbard, the Longyearbyen coal-fired power plant is considered to be one of the major local sources ... -

Polycyclic aromatic hydrocarbons modulate the activity of Atlantic cod (Gadus morhua) vitamin D receptor paralogs in vitro
(Peer reviewed; Journal article, 2021)Vitamin D receptor (VDR) mediates the biological function of the steroid hormone calcitriol, which is the metabolically active version of vitamin D. Calcitriol is important for a wide array of physiological functions, ... -
Polycycliske aromatiske hydrokarboner i det marine miljø - En forurensning fra aluminiums-industriens smelteverk

Polymorphism of serum transferrin in cod
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1966)Sera from 682 cod from six different localities along the Norwegian coast and in the Barents Sea have been investigated by starch/agar gel electrophoresis. Eleven different patterns composed by five molecular types have ... -
Polystyrene nanoplastics enhance the toxicological effects of DDE in zebrafish (Danio rerio) larvae
(Peer reviewed; Journal article, 2022)Anthropogenic releases of plastics, persistent organic pollutants (POPs), and heavy metals can impact the environment, including aquatic ecosystems. Nanoplastics (NPs) have recently emerged as pervasive environmental ... -
Poor feeding opportunities and reduced condition factor for salmon post-smolts in the Northeast Atlantic Ocean
(Peer reviewed; Journal article, 2021)During the last few decades, many wild Atlantic salmon populations have declined dramatically. One possible contributing factor for the decline is reduced prey availability at sea. Here, we examine post-smolt diet and ... -
Population dynamic regulators in an empirical predator-prey system
(Peer reviewed; Journal article, 2021)Capelin (Mallotus villosus) is a short-lived (1–4 years) fish species, that plays a crucial role by dominating the intermediate trophic level in the Barents Sea. Several episodes of extreme biomass decline (collapse) have ... -
Population dynamics of cod Gadus morhua in the North Sea region: biological density-dependent and climatic density-independent effects
(Journal article; Peer reviewed, 2005-11-04)Through the statistical modeling of monitoring data, we assess the ecological interlinkages between cod Gadus morhua L. in the North Sea, Skagerrak and Kattegat—regions which typically have been considered separate management ... -
Population dynamics of salmon lice Lepeophtheirus salmonis on Atlantic salmon and sea trout
(Journal article; Peer reviewed, 2005-04-13)The salmon louse Lepeophtheirus salmonis is a common ectoparasite of both farmed and wild salmonids in the marine environment, and can have a significant negative effect on the survival and growth of its host. To facilitate ... -
Population genetic analysis reveals a geographically limited transition zone between two genetically distinct Atlantic salmon lineages in Norway
(Journal article; Peer reviewed, 2019)Atlantic salmon is characterized by a high degree of population genetic structure throughout its native range. However, while populations inhabiting rivers in Norway and Russia make up a significant proportion of salmon ... -
Population genetic structure in a deepwater fish Coryphaenoides rupestris: patterns and processes
(Journal article; Peer reviewed, 2012-07-24)We observed significant genetic structure in a widely distributed North Atlantic demersal deepwater fish, the roundnose grenadier Coryphaenoides rupestris (Pisces: Macro - uridae). The overall estimate of genetic ... -
Population genetic structure of grey seals (Halichoerus grypus) : Diversity, differentiation and prospects for genetic population assignment with special reference to Norwegian waters
(ICES CM documents;2007/L:25, Working paper, 2007)Population structure of grey seal breeding colonies in Norway (n=300), Northwest Russia (n=40) and Scotland (n=100) is currently being investigated based on Mt-DNA control region sequencing and fragment analysis (8 ... -
Population genetic structure of the parasitic copepod Lepeophtheirus salmonis throughout the Atlantic
(Journal article; Peer reviewed, 2011-04-12)The parasitic copepod Lepeophtheirus salmonis is responsible for huge economic losses in the salmonid aquaculture industry, and has been linked with declines of wild salmonid populations. In order to elucidate population ... -
Population Genetic Structure of the Spotted Wolffish, Anarhichas minor, in the North Atlantic
(Journal article; Peer reviewed, 2008)The genetic population structure of spotted wolffish Anarhichas minor (Olafsen) in the North Atlantic was investigated by allozyme electrophoresis and by PCR based RFLP variation in mtDNA. Samples were collected from five ... -
Population genetic structure of wrasses used as cleanerfish in Atlantic salmon farming in Norway
(ICES CM Documents;1993/G:30, Working paper, 1993)The increasing use of wrasses as cleaner fish in the salmon farming industry has created local fishery in many regions in Norway. In several cases, live fish have been transported between regions without knowledge of the ... -
