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 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 ... -
Population structure and historical demography of eastern North Atlantic harbour porpoises inferred through mtDNA sequences
(Journal article; Peer reviewed, 2006-12-07)The harbour porpoise Phocoena phocoena experiences high rates of incidental mortality in commercial fisheries, and in some areas these rates are sufficiently high to justify concern over population sustainability. Given ... -
Population structure discovered in juveniles of Greenland halibut (Reinhardtius hippoglossoides Walbaum, 1792)
(Peer reviewed; Journal article, 2023)Understanding the genetic differentiation among populations of most marine fish requires investigating the differences among spawning grounds. However, this can be challenging as spawning grounds for some species are not ... -
Population structure in Atlantic cod in the eastern North Sea-Skagerrak-Kattegat: early life stage dispersal and adult migration
(Journal article; Peer reviewed, 2016-02-03) -
Population structure of bycaught harbour porpoise (Phocoena phocoena) in Norway
(Peer reviewed; Journal article, 2020) -
Population structure of European sprat (Sprattus sprattus) in the Greater North Sea ecoregion revealed by otolith shape analysis
(Peer reviewed; Journal article, 2021)A successful discrimination of fish populations is essential for sustainable management and assessment. Otolith shape analysis has been used on several species to reveal their population structure. Our aim was to use the ... -
Positive and negative feedbacks related to the Arctic Oscillation revealed by air-sea heat fluxes
(Journal article; Peer reviewed, 2019)The NCEP reanalysis data of surface heat fluxes and other related data are used to study their relationship with the Arctic Oscillation (AO). Positive and negative high correlation regions (HCR) between heat fluxes and the ... -
A positive temperature-dependent effect of elevated CO<inf>2</inf> on growth and lipid accumulation in the planktonic copepod, Calanus finmarchicus
(Peer reviewed; Journal article, 2022)Calanus finmarchicus were reared from eggs to adults at 12°C and 16°C with non-limiting food in combination with ambient (600 μatm) and high (1100 μatm) pCO2. These conditions are likely to be encountered by the species ... -
Possible adverse impact of contaminants on Atlantic cod population dynamics in coastal ecosystems
(Journal article; Peer reviewed, 2019)While many in-laboratory ecotoxicological studies have shown the adverse impact of pollutants to the fitness of an individual, direct evidence from the field on the population dynamics of wildlife animals has been lacking. ... -
Possible future scenarios for two major Arctic Gateways connecting Subarctic and Arctic marine systems: I. Climate and physical-chemical oceanography
(Peer reviewed; Journal article, 2021)We review recent trends and projected future physical and chemical changes under climate change in transition zones between Arctic and Subarctic regions with a focus on the two major inflow gateways to the Arctic, one in ... -
Possible influence of salmon farming on long-term resident behaviour of wild saithe (Pollachius virens L.)
(Journal article; Peer reviewed, 2014-06-13)The culture of Atlantic salmon is one of the most developed aquaculture industries in the world. The production from smolt to market size usually takes place in sea cages in open waters, and these structures tend to attract ... -
Post-escape dispersal of juvenile Atlantic cod Gadus morhua from Norwegian fish farms and their potential for recapture
(Peer reviewed; Journal article, 2013) -
Post-release effects of catch and release angling for sea trout: Mortality, growth and wound healing
(Peer reviewed; Journal article, 2023)Sea trout (anadromous brown trout, Salmo trutta L.) is a popular recreational angling target species in the Baltic Sea region and beyond. Across countries, a substantial part of angled sea trout is released after capture ... -
Postglacial species arrival and diversity buildup of northern ecosystems took millennia
(Peer reviewed; Journal article, 2022)What drives ecosystem buildup, diversity, and stability? We assess species arrival and ecosystem changes across 16 millennia by combining regional-scale plant sedimentary ancient DNA from Fennoscandia with near-complete ... -
Postprocessing system for echo sounder data
(Journal article; Peer reviewed, 1991)Echo sounding is a powerful and widely used technique for remote sensing of the marine environment. In order to enhance the power of the echo sounder, a postprocessing system has been designed and realized in standard ... -
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. ... -
Potential disease interaction reinforced: double-virusinfected escaped farmed Atlantic salmon, Salmo salar L., recaptured in a nearby river
(Journal article; Peer reviewed, 2014-01-27)The role of escaped farmed salmon in spreading infectious agents from aquaculture to wild salmonid populations is largely unknown. This is a case study of potential disease interaction between escaped farmed and wild fish ... -
Potential effects of reduced riverine inorganic particle loading on water quality in the Oslofjord region
