Overexploitation, Recovery, and Warming of the Barents Sea Ecosystem During 1950–2013
(Peer reviewed; Journal article, 2021)The Barents Sea (BS) is a high-latitude shelf ecosystem with important fisheries, high and historically variable harvesting pressure, and ongoing high variability in climatic conditions. To quantify carbon flow pathways ... -
Overexpression of cyclooxygenase-2 in adipocytes reduces fat accumulation in inguinal white adipose tissue and hepatic steatosis in high-fat fed mice
(Journal article; Peer reviewed, 2019)Cyclooxygenases are known as important regulators of metabolism and immune processes via conversion of C20 fatty acids into various regulatory lipid mediators, and cyclooxygenase activity has been implicated in browning ... -
Overwintering behaviour of yellow-stage European eel (Anguilla anguilla) in a natural marine fjord system
(Peer reviewed; Journal article, 2022)Like many animals, northern temperate eel can enter a hibernation-like state and become dormant during the winter. Knowledge of overwintering behaviour in eel is sparse and mainly based on anecdotal observations and a few ... -
Overwintering distribution, inflow patterns and sustainability of Calanus finmarchicus in the North Sea
(Peer reviewed; Journal article, 2021)Calanoid copepods are key taxa in the North Sea as they are the main food source for many fish stocks, such as herring, mackerel and cod. In this study we use an individual-based model for Calanus finmarchicus embedded in ... -
Ovipleistophora gen. n., a new genus for Pleistophora mirandellae-like microsporidia
(Journal article; Peer reviewed, 2002-03-11)Based on ultrastructural study and molecular analysis, a new genus, Ovipleistophora, is established for Pleistophora mirandellae-like microsporidia from roach and ruff oocytes, Unlike Pleistophora, Ovipleistophora has a ... -
Oxygen and temperature influence the distribution of deepwater Cape hake Merluccius paradoxus in the southern Benguela: a GAM analysis of a 10-year time-series
(Journal article; Peer reviewed, 2019)Generalised additive models (GAMs) were applied to survey data to assess the influence of dissolved oxygen, water temperature and year of sampling upon the presence/absence of small (≤15 cm TL), medium (16–34 cm TL) and ... -
Oxygen gradients affect behaviour of caged Atlantic salmon Salmo salar
(Peer reviewed; Journal article, 2017)Dissolved oxygen (DO) conditions in marine aquaculture cages are heterogeneous and fluctuate rapidly. Here, by temporarily wrapping a tarpaulin around the top 0 to 6 m of a marine cage (~2000 m3), we manipulated DO to ... -
Oxygen Uptake and Osmotic Balance of Atlantic Salmon in Relation to Exercise and Salinity Acclimation
(Peer reviewed; Journal article, 2018)The fish gill is subject to an osmorespiratory compromise in physiologically demanding situations where conditions that favor gas exchange may compromise osmotic balance, especially when large gradients between the blood ... -
Pacific and Atlantic Lepeophtheirus salmonis (Krøyer, 1838) are allopatric subspecies: Lepeophtheirus salmonis salmonis and L. salmonis oncorhynchi subspecies novo
(Journal article; Peer reviewed, 2014-03-14)Background The salmon louse Lepeophtheirus salmonis is a parasitic copepod that infects salmonids in the Pacific and Atlantic oceans. Although considered as a single species, morphological and biological differences have ... -
Pan-Arctic suitable habitat model for Greenland halibut
(Peer reviewed; Journal article, 2021)Deep-sea marine fishes support important fisheries but estimates of their distributions are often incomplete as the data behind them may reflect fishing practices, access rights, or political boundaries, rather than actual ... -
The pantophysin gene and its relationship with survival in early life stages of Atlantic cod: Pantophysin in Atlantic cod
(Peer reviewed; Journal article, 2020)Genetic markers are widely used in fisheries management around the world. While the genetic structure and markers selected are usually based on samples from the wild, very few controlled experiments have been carried out ... -
A Paradise for Rare Species: Tanaidacean Fauna of the West African Continental Margin
(Peer reviewed; Journal article, 2022)The benthic ecology of the Gulf of Guinea is critically understudied, and knowledge about the composition and biodiversity of the tanaidacean communities remains lacking. Our analysis of tanaidacean collection from 270 ... -
ParallelStructure: A R Package to Distribute Parallel Runs of the Population Genetics Program STRUCTURE on Multi-Core Computers
(Journal article; Peer reviewed, 2013-07-29)This software package provides an R-based framework to make use of multi-core computers when running analyses in the population genetics program STRUCTURE. It is especially addressed to those users of STRUCTURE dealing ... -
Parameter-sparse modification of Fourier methods to analyse the shape of closed contours with application to otolith outlines
(Journal article; Peer reviewed, 2016-02-05)Elliptical Fourier descriptors (EFDs) have been used extensively in shape analysis of closed contours and have a range of marine applications, such as automatic identification of fish species and discrimination between ... -
Parametric acoustic array and P. J. Westervelt: A tribute

Paranucleospora theridion (Microsporidia) infection dynamics in farmed Atlantic salmon Salmo salar put to sea in spring and autumn
(Journal article; Peer reviewed, 2012-10-10)The microsporidian Paranucleospora theridion (syn. Desmozoon lepeophtheirii) is a parasite of Atlantic salmon Salmo salar and also a hyperparasite of the salmon louse Lepeophtheirus salmonis. The parasite develops 2 types ... -
Parasite development affect dispersal dynamics; infectivity, activity and energetic status in cohorts of salmon louse copepodids
(Peer reviewed; Journal article, 2020)The salmon louse, Lepeophtheirus salmonis, is a parasitic copepod infecting wild and farmed salmonid fishes in the northern hemisphere. It has a direct lifecycle with a planktonic dispersal phase and an infective copepodid ... -
Parasite management in aquaculture exerts selection on salmon louse behaviour
(Peer reviewed; Journal article, 2021)The evolution of pest resistance to management strategies is a major challenge for farmed systems. Mitigating the effects of pest adaptation requires identifying the selective pressures imposed by these strategies. In ... -
