Digital Data Help Explain Drivers of Angler Satisfaction: An Example from Southern Norway
(Peer reviewed; Journal article, 2022)We analyzed trip-level self-reports collected by a cell phone app to understand angler satisfaction of fishing for sea trout Salmo trutta (anadromous Brown Trout) in southern Norway. We found no clear support for a positive ... -
Digital fisheries data in the Internet age: Emerging tools for research and monitoring using online data in recreational fisheries
(Peer reviewed; Journal article, 2022)Recreational fisheries are diverse in scale, scope, and participation worldwide, constituting an important ecosystem service of marine and freshwater ecosystems. Management of these socio-ecological systems is challenged ... -
Direct and indirect climate forcing in a multi-species marine system
(Journal article; Peer reviewed, 2010-10)Interactions within and between species complicate quantification of climate effects, by causing indirect, often delayed, effects of climate fluctuations and compensation of mortality. Here we identify direct and indirect ... -
Direct and indirect effects of sea ice cover on major zooplankton groups and planktivorous fishes in the Barents Sea
(Peer reviewed; Journal article, 2019)Reductions in Arctic sea ice affect marine food webs through a multitude of direct and indirect effects. We here analysed direct, indirect, and delayed associations between winter sea ice cover and year-to-year changes in ... -
Direct evidence of increased natural mortality of a wild fish caused by parasite spillback from domestic conspecifics
(Peer reviewed; Journal article, 2023)Parasite spillback from domestic animals can distort the balance between host and parasites in surrounding wildlife, with potential detrimental effects on wild populations. In aquatic environments, parasite spillback from ... -
Discards of cod (Gadus morhua) in the Norwegian coastal fisheries: improving past and future estimates
(Peer reviewed; Journal article, 2022)Discarding can be an unknown source of biases and uncertainties in stock assessments. Discarding patterns and quantities vary so a routine methodology for estimating discards is important to give a better picture of total ... -
Discerning the Management-Relevant Ecology and Distribution of Sea Pens (Cnidaria: Pennatulacea) in Norway and Beyond
(Peer reviewed; Journal article, 2021)Sea pens are considered to be of conservation relevance according to multiple international legislations and agreements. Consequently, any information about their ecology and distribution should be of use to management ... -
Discovery of a Distinctive Spotted Color Pattern in the Cuskeel Neobythites unicolor (Teleostei, Ophidiidae) Based on Underwater-Vehicle Dives, with New Records from the Southern and Eastern Caribbean
(Journal article; Peer reviewed, 2019)In situ images and/or collection of seven specimens by underwater-vehicle dives at 269–609 m depth off Curaçao, Dominica, and Puerto Rico (S, E, and NE Caribbean) revealed new records and a previously unknown, distinctive ... -
Discovery of a novel integron-borne aminoglycoside resistance gene present in clinical pathogens by screening environmental bacterial communities
(Peer reviewed; Journal article, 2020)Background New antibiotic resistance determinants are generally discovered too late, long after they have irreversibly emerged in pathogens and spread widely. Early discovery of resistance genes, before or soon after their ... -
Discovery of polycyclic aromatic acid metabolites in fish exposed to the petroleum compounds 1-methylphenanthrene and 1,4-dimethylphenanthrene
(Peer reviewed; Journal article, 2024)Most of the polycyclic aromatic hydrocarbons (PAHs) in petroleum are alkylated (alkyl PAHs), still the metabolism of these alkyl PAHs to the expected acid products (polycyclic aromatic acids; PAAs) has yet to be demonstrated ... -
Discrete water quality sampling at open-water aquaculture sites: limitations and strategies
(Peer reviewed; Journal article, 2016) -
Disease interaction and pathogens exchange between wild and farmed fish populations with special reference to Norway
(Journal article; Peer reviewed, 2011-05-21)Norway has the largest salmon-farming industry in the world, an industry that is still growing, and in recent years production of marine species like Atlantic cod has also increased. At the same time, Norway has the world's ... -
Diseases of farmed Atlantic salmon Salmo salar associated with infections by the microsporidian Paranucleospora theridion
(Journal article; Peer reviewed, 2011-03-16)The microsporidian Paranucleospora theridion was discovered in Atlantic salmon Salmo salar suffering from proliferative gill disease in a marine farm in western Norway in 2008. The parasite develops in cells of the ... -
Diseases, prophylaxis and treatment of the Atlantic halibut Hippoglossus hippoglossus: a review
(Journal article; Peer reviewed, 2001)After substantial investments in research, the Atlantic halibut Hippoglossus hippoglossus is now being cultivated commercially in Norway, Iceland, Scotland and Canada. As with other domesticated species, disease problems ... -
Disentangling conditional effects of multiple regime shifts on Atlantic cod productivity
(Peer reviewed; Journal article, 2020)Regime shifts are increasingly prevalent in the ecological literature. However, definitions vary and detection methods are still developing. Here, we employ a novel statistical algorithm based on the Bayesian online ... -
Disentangling structural genomic and behavioral barriers in a sea of connectivity
(Journal article; Peer reviewed, 2019)Genetic divergence among populations arises through natural selection or drift and is counteracted by connectivity and gene flow. In sympatric populations, isolating mechanisms are thus needed to limit the homogenizing ... -
Disentangling the causes of maturation trends in exploited fish populations
(Journal article; Peer reviewed, 2007-04-16) -
Disentangling the effects of sex, life history and genetic background in Atlantic salmon: Growth, heart and liver under common garden conditions: Atlantic salmon: Growth, heart & liver
(Peer reviewed; Journal article, 2020)Livestock domestication has long been a part of agriculture, estimated to have first occurred approximately 10 000 years ago. Despite the plethora of traits studied, there is little understanding of the possible impacts ... -
Disentangling the key drivers of salmon louse Lepeophtheirus salmonis fecundity using multiyear field samples
(Peer reviewed; Journal article, 2023)Planktonic salmon louse Lepeophtheirus salmonis salmonis larvae produced at sal - mon farms spread to and infect both wild and farmed salmonids. Understanding and forecasting the production and distribution of these larval ... -
Disparate movement behavior and feeding ecology in sympatric ecotypes of Atlantic cod
(Peer reviewed; Journal article, 2021)Coexistence of ecotypes, genetically divergent population units, is a widespread phenomenon, potentially affecting ecosystem functioning and local food web stability. In coastal Skagerrak, Atlantic cod (Gadus morhua) occur ...
