Practicing Responsible Research and Innovation in a crowdsourcing project
(Peer reviewed; Journal article, 2019)The paper discusses the operationalization of responsible research and innovation (RRI), drawing on empirical materials from a research project that explored ICT-enabled tools and methods for crowdsourcing in urban ... -
Pre-project: Climate Change as an Opportunity towards Adaptive Sustainable Aquaculture (CADINAL)
(NIVA-rapport;6563, Research report, 2013)Cultured food fish currently accounts for nearly 50 % of the global consumption. India and Norway are the world’s second and seventh largest aquaculture producers respectively, thus aquaculture is considered to be a sector ... -
Predation mortality from ambush and cruising predators on newly-settled 0-group gadoids
(Peer reviewed; Journal article, 2020)We investigated predation from an ambush predator (shorthorn sculpin) and two cruising predators (Atlantic cod and saithe) on bottom-settled 0-group cod and saithe juveniles in a fjord in northern Norway. Stomach contents ... -
Predation of Atlantic salmon across ontogenetic stages and impacts on populations
(Peer reviewed; Journal article, 2023)Managers and stakeholders increasingly ask whether predation is a driving force behind the poor status of many species, and whether predator control is likely to be a successful management action to intervene. We review ... -
Predation risk alters life history strategies in an oceanic copepod
(Peer reviewed; Journal article, 2020)The ubiquitous oceanic copepod Calanus finmarchicus is the major link between primary producers and important fish stocks in the North Atlantic Ocean and adjacent seas. Despite over a century of research on growth and ... -
Predators of the destructive sea urchin grazer Strongylocentrotus droebachiensis on the Norwegian coast
(Journal article; Peer reviewed, 2014)In central Norway, populations of the green sea urchin Strongylocentrotus droe-bachiensis are collapsing, but the factors controlling its population density have not yet been elucidated. Through field sampling, we identified ... -
Predicting acidification of North American lakes
(NIVA-rapport;1477, Research report, 1983)An empirical model for lake acidification developed in Norway also satisfactorily accounts for observed water chemistry in oligotrophic clearwater, softwater lakes elsewhere in Europe and in North America. This model can ... -
Predicting Environmental Risks of Pharmaceuticals from Wholesale Data: An Example from Norway
(Peer reviewed; Journal article, 2023)Environmental risk assessment (ERA) of pharmaceuticals relies on available measured environmental concentrations, but often such data are sparse. Predicted environmental concentrations (PECs), calculated from sales weights, ... -
Predicting Lake Quality for the Next Generation: Impacts of Catchment Management and Climatic Factors in a Probabilistic Model Framework
(Journal article; Peer reviewed, 2019)Lake ecosystems across the world are under combined pressures of eutrophication and climate change, which increase the risk of harmful cyanobacteria blooms, reduced ecological status, and degraded ecosystem services. In ... -
Predicting the nationwide outmigration timing of Atlantic salmon (Salmo salar) smolts along 12 degrees of latitude in Norway
(Peer reviewed; Journal article, 2021)Aim Accurate predictions about transition timing of salmon smolts between freshwater and marine environments are key to effective management. We aimed to use available data on Atlantic salmon smolt migration to predict the ... -
Prediction of Extraordinarily High Floods Emerging From Heterogeneous Flow Generation Processes
(Peer reviewed; Journal article, 2023)River floods are generated by various processes that, if disregarded, may induce errors in flood hazard assessment. This is particularly relevant where events extraordinarily larger than the typical floods have been observed, ... -
Preliminary proposals for classification of marine environmental quality respecting micropollutants in water, sediments and selected organisms
(NIVA-rapport;2738, Research report, 1992)A compilation of water quality criteria and information about "background levels" of micropollutants (selected metals, organochlorines, polycyclic aromatic hydrocarbons) have been used as basis for proposals of marine ... -
Prenatal exposure to persistent organic pollutants in Northern Tanzania and their distribution between breast milk, maternal blood, placenta and cord blood
(Journal article; Peer reviewed, 2019)Human exposure to persistent organic pollutants (POPs) begins during pregnancy and may cause adverse health effects in the fetus or later in life. The present study aimed to assess prenatal POPs exposure to Tanzanian infants ... -
Prestvannet i Troms. Vurdering av tilgroing 2005
(NIVA-rapport;5131, Research report, 2006)Hensikten med prosjektet har vært å kartlegge vegetasjonsutbredelsen i innsjøen og vurdere om det har skjedd en tilgroing. Tilgroingssituasjonen i Prestvannet er preget av flyteøyene, som for en stor del ser ut til å stamme ... -
Preying on seals pushes killer whales from Norway above pollution effects thresholds
(Peer reviewed; Journal article, 2020)Killer whales (Orcinus orca) are at risk from high levels of biomagnifying pollutants, such as polychlorinated biphenyls (PCBs) and mercury (Hg). Previous toxicological risk assessments for the Norwegian killer whale ... -
Primary hepatocytes from Arctic char (Salvelinus alpinus) as a relevant Arctic in vitro model for screening contaminants and environmental extracts
(Journal article; Peer reviewed, 2017)Contaminants find their way to the Arctic through long-range atmospheric transport, transport via ocean currents, and through increased anthropogenic activity. Some of the typical pollutants reaching the Arctic (PAHs, PCBs) ... -
