Diversity and seasonal development of large zooplankton along physical gradients in the Arctic Barents Sea
(Peer reviewed; Journal article, 2023)Due to ongoing climate change, a new Arctic Ocean ecosystem is emerging. Within the framework of the Nansen Legacy project, we investigated the community composition of the large zooplankton and its seasonal development ... -
Diversity of hard-bottom fauna relative to environmental gradients in Kongsfjorden, Svalbard
(Journal article; Peer reviewed, 2013-04-26)A baseline study of hard-bottom zoobenthos in relation to environmental gradients in Kongsfjorden, a glacial fjord in Svalbard, is presented, based on collections from 1996 to 1998. The total species richness in 62 samples ... -
Diversity, distribution patterns and indicatory potential of echinoderm communities of the tropical East Atlantic (Gulf of Guinea): Influence of multiple natural and anthropogenic factors along a 25–1000 m depth gradient
(Peer reviewed; Journal article, 2023)All earlier studies of the West African echinoderm fauna have focused on taxonomy, and general knowledge about benthic community responses to various human related threats are poorly diagnosed and not monitored along the ... -
Diversity, habitat endemicity and trophic ecology of the fauna of Loki’s Castle vent field on the Arctic Mid-Ocean Ridge
(Peer reviewed; Journal article, 2024)Loki’s Castle Vent Field (LCVF, 2300 m) was discovered in 2008 and represents the first black-smoker vent field discovered on the Arctic Mid-Ocean Ridge (AMOR). However, a comprehensive faunal inventory of the LCVF has not ... -
DNA and scale reading to identify repeat spawning in Atlantic salmon: Unique insights into patterns of iteroparity
(Peer reviewed; Journal article, 2023)Iteroparity represents an important but often overlooked component of life history in anadromous Atlantic salmon. Here, we combined individual DNA profiling and scale reading to identify repeat spawners among ~8000 adult ... -
DNA barcoding confirms the first record of a Desmodema polystictum (Ogilby, 1898) egg and all-time high adult catches in the Indian Ocean.
(Peer reviewed; Journal article, 2019)The eggs of Polka-dot ribbonfish Desmodema polystictum have been recorded for the first time in the Indian Ocean. Although the only previous information on eggs from this species consists of line drawings from 1973 (Pacific ... -
DNA damage and health effects in juvenile haddock (Melanogrammus aeglefinus) exposed to PAHs associated with oil-polluted sediment or produced water
(Peer reviewed; Journal article, 2020)The research objective was to study the presence of DNA damages in haddock exposed to petrogenic or pyrogenic polyaromatic hydrocarbons (PAHs) from different sources: 1) extracts of oil produced water (PW), dominated by ... -
DNA-analysis to monitor fisheries and aquaculture: Too costly?
(Journal article; Peer reviewed, 2018)Evidence from DNA‐analysis is commonplace in human criminal investigations, and while it is increasingly being used in wildlife crime, to date, its application to control and enforcement activities in fisheries and aquaculture ... -
Dnd knockout ablates germ cells and demonstrates germ cell independent sex differentiation in Atlantic salmon
(Journal article; Peer reviewed, 2016-02-18)Introgression of farmed salmon escapees into wild stocks is a major threat to the genetic integrity of wild populations. Using germ cell-free fish in aquaculture may mitigate this problem. Our study investigated whether ... -
Do abiotic mechanisms determine interannual variability in length-at-age of juvenile Arcto-Norwegian cod?
(Journal article; Peer reviewed, 2002)For the large Arcto-Norwegian stock of cod (Gadus morhua L.) in the Barents Sea, year-to-year variability in growth is well documented. Here three hypotheses for the observed inverse relation between abundance and the mean ... -
Do accurate stock estimates increase harvest and reduce variability in fisheries yields?
(Journal article; Peer reviewed, 2011-03-22)Fisheries managers normally make decisions based on stock abundance estimates subject to process, observation, and model uncertainties. Considerable effort is invested in gathering information about stock size to decrease ... -
Do background levels of the pesticide pirimiphosmethyl in plant-based aquafeeds affect food safety of farmed Atlantic salmon?
(Peer reviewed; Journal article, 2020)The substitution of fish oil and fishmeal with plant-based ingredients in commercial aquafeeds for Atlantic salmon, may introduce novel contaminants that have not previously been associated with farmed fish. The organophosphate ... -
Does density influence relative growth performance of farm, wild and F1 hybrid Atlantic salmon in semi-natural and hatchery common garden conditions?
(Journal article; Peer reviewed, 2016-07-06)The conditions encountered by Atlantic salmon, Salmo salar L., in aquaculture are markedly different from the natural environment. Typically, farmed salmon experience much higher densities than wild individuals, and may ... -
Does Domestication Cause Changes in Growth Reaction Norms? A Study of Farmed, Wild and Hybrid Atlantic Salmon Families Exposed to Environmental Stress
(Journal article; Peer reviewed, 2013-01-31)One of the most important traits linked with the successful domestication of animals is reducing their sensitivity to environmental stressors in the human controlled environment. In order to examine whether domestication ... -
Does grab size influence sampled macrofauna composition? A test conducted on deep-sea communities in the northeast Atlantic
(Journal article; Peer reviewed, 2019)In deep-sea surveys, heavy gears are often preferred to effectively collect macro benthos while smaller samplers are sufficient in coastal and shallow areas. However, there are few comparative studies of the samples retained ... -
Does operational oceanography address the needs of fisheries and applied environmental scientists?
(Journal article; Peer reviewed, 2011)Although many oceanographic data products are now considered operational, continued dialogue between data producers and their user communities is still needed. The fisheries and environmental science communities have often ... -
Does Presence of a Mid-Ocean Ridge Enhance Biomass and Biodiversity?
(Journal article; Peer reviewed, 2013-05-02)In contrast to generally sparse biological communities in open-ocean settings, seamounts and ridges are perceived as areas of elevated productivity and biodiversity capable of supporting commercial fisheries. We investigated ... -
Does Sex-Selective Predation Stabilize or Destabilize Predator-Prey Dynamics?
(Journal article; Peer reviewed, 2008-07-16)Background: Little is known about the impact of prey sexual dimorphism on predator-prey dynamics and the impact of sexselective harvesting and trophy hunting on long-term stability of exploited populations. Methodology ... -
