Planctomycetes as a vital constituent of the microbial communities inhabiting different layers of the meromictic Lake Sælenvannet (Norway)
(Peer reviewed; Journal article, 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 ... -
Planktic foraminiferal and pteropod contributions to carbon dynamics in the Arctic Ocean (north Svalbard margin)
(Peer reviewed; Journal article, 2021)Planktic foraminifera and shelled pteropods are some of the major producers of calcium carbonate (CaCO3) in the ocean. Their calcitic (foraminifera) and aragonitic (pteropods) shells are particularly sensitive to changes ... -
Plastsøppel på havbunnen kartlagt av Mareano
(Rapport fra havforskningen;2024 - 12, Research report, 2024)Miljødirektoratet har bedt Havforskningsinstituttet om å analysere observasjonsdata for søppel på havbunnen for å øke kunnskapen om hvor mye plastavfall utgjør av dette. Mareano kartlegger søppel på havbunnen som del av ... -
A Pleistocene legacy structures variation in modern seagrass ecosystems
(Peer reviewed; Journal article, 2022)Distribution of Earth’s biomes is structured by the match between climate and plant traits, which in turn shape associated communities and ecosystem processes and services. However, that climate–trait match can be disrupted ... -
Ploidy elicits a whole-genome dosage effect: growth of triploid Atlantic salmon is linked to the genetic origin of the second maternal chromosome set
(Peer reviewed; Journal article, 2017) -
Polar cod egg and larval drift patterns in the Svalbard archipelago
(Journal article; Peer reviewed, 2019)Spawning of polar cod (Boreogadus saida) in the vicinity of the Svalbard archipelago has not been directly observed. From the distribution pattern of polar cod 0-group observed during annual monitoring of the Barents Sea, ... -
Polar cod in jeopardy under the retreating Arctic sea ice
(Journal article; Peer reviewed, 2019)The Arctic amplification of global warming is causing the Arctic-Atlantic ice edge to retreat at unprecedented rates. Here we show how variability and change in sea ice cover in the Barents Sea, the largest shelf sea of ... -
Polar Fresh Water in a Changing Global Climate: Linking Arctic and Southern Ocean Processes
(Peer reviewed; Journal article, 2023) -
Polarfrontens fysiske beskaffenhet og biologiske implikasjoner – en verdi- og sårbarhetsvurdering av polarfronten i Barentshavet
(Fisken og Havet;8-2018, Research report, 2018)Polarfronten er definert som skillet i Barentshavet mellom relativt varme og salte vannmasser av atlantisk opprinnelse og kaldere og ferskere vannmasser av arktisk opprinnelse. På grunn av de fysiske særtrekkene og ... -
Poleward shifts in marine fisheries under Arctic warming
(Peer reviewed; Journal article, 2021)As global warming makes the Arctic Ocean more accessible, concerns have been raised about the environmental consequences of a possible expansion of commercial fisheries into pristine marine ecosystems. Using a recently ... -
Poleward spawning of Atlantic mackerel (Scomber scombrus) is facilitated by ocean warming but triggered by energetic constraints
(Peer reviewed; Journal article, 2023)The Northeast Atlantic mackerel is an income breeder with indeterminate fecundity, spawning in multiple batches at optimal temperatures around 11°C in the upper water column during February–July along the continental shelf ... -
Polyaromatic hydrocarbons in pollution: a heart-breaking matter
(Journal article; Peer reviewed, 2019)Air pollution is associated with detrimental effects on human health, including decreased cardiovascular function. However, the causative mechanisms behind these effects have yet to be fully elucidated. Here we review the ... -
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 ... -

(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, ... -
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 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 structure and connectivity in the genus Molva in the Northeast Atlantic
(Peer reviewed; Journal article, 2023)In fisheries, operational management units and biological data often do not coincide. In many cases, this is not even known due to the lack of information about a species’ population structure or behaviour. This study ...
