Using environmental monitoring data from apex predators for chemicals management: towards better use of monitoring data from apex predators in support of prioritisation and risk assessment of chemicals in Europe
(Peer reviewed; Journal article, 2022)A large number of apex predator samples are available in European research collections, environmental specimen banks and natural history museums that could be used in chemical monitoring and regulation. Apex predators ... -
Using Food Webs and Metabolic Theory to Monitor, Model, and Manage Atlantic Salmon—A Keystone Species Under Threat
(Peer reviewed; Journal article, 2021)Populations of Atlantic salmon are crashing across most of its natural range: understanding the underlying causes and predicting these collapses in time to intervene effectively are urgent ecological and socioeconomic ... -
Using mussel as a global bioindicator of coastal microplastic pollution
(Journal article; Peer reviewed, 2019)The ubiquity and high bioavailability of microplastics have an unknown risk on the marine environment. Biomonitoring should be used to investigate biotic impacts of microplastic exposure. While many studies have used mussels ... -
Using Passive Samplers to Track per and Polyfluoroalkyl Substances (PFAS) Emissions From the Paper Industry: Laboratory Calibration and Field Verification
(Peer reviewed; Journal article, 2021)Per and polyfluoroalkyl substances (PFAS) are becoming more stringently regulated and as such, a more diverse suite of environmental monitoring methods is needed. In this work a polar organic chemical integrative sampler ... -
Utslipp av antibiotikaresistensgener med behandlet avløpsvann til resipienten
(Journal article; Peer reviewed, 2018)Forekomsten av utvalgte markørgener for antimikrobiell resistens (AMR) i vannprøver tatt fra utslippet av tre norske avløpsrenseanlegg ble kvantifisert. 16S rRNA, Intl1 og Sul1 er de tre dominerende antibiotikaresistensgenene ... -
Utslipp til sjø – kan enkle modeller gi tilstrekkelig grunnlag for vurdering av spredning, fortynning og surhetsgrad?
(Journal article; Peer reviewed, 2018)Det forelå i 2016 ca. 2500 utslippstillatelser for utslipp til kystvann i Norge. Til tross for mange bestrebelser på å redusere utslippene må en forvente at en også i fremtiden må leve med betydelige utslipp til sjø. For ... -
Utvidelse av Fv. 564 Ulsetstemma-Slettestølsvegen. Forundersøkelser av økologisk tilstand i vassdrag
(NIVA-rapport;7331, Research report, 2018)I forbindelse med planarbeid for utvidelse av Fv. 564 Ulset-Slettestølvegen i Åsane i Bergen er det utført en forundersøkelse av økologisk tilstand i vassdrag innenfor planområdet, og vurdering av naturfaglige verdier. ... -
UV radiation affects antipredatory defense traits in Daphnia pulex
(Peer reviewed; Journal article, 2020)In aquatic environments, prey perceive predator threats by chemical cues called kairomones, which can induce changes in their morphology, life histories, and behavior. Predator‐induced defenses have allowed for prey, such ... -
Validation of a Method for Extracting Microplastics from Complex, Organic-Rich, Environmental Matrices
(Journal article; Peer reviewed, 2018)Complex and organic-rich solid substrates such as sludge and soil have been shown to be contaminated by microplastics; however, methods for extracting plastic particles have not yet been systemically tested or standardized. ... -
Valuing the ecosystem service benefits from kelp forest restoration: A choice experiment from Norway
(Peer reviewed; Journal article, 2021)Habitat loss and degradation are recognised as the most important causes of species decline and extinction in marine ecosystems. It is also widely recognised that a range of restoration actions are now essential to halt ... -
Variability and decadal trends in the Isfjorden (Svalbard) ocean climate and circulation – An indicator for climate change in the European Arctic
(Peer reviewed; Journal article, 2020)Isfjorden, a broad Arctic fjord in western Spitsbergen, has shown significant changes in hydrography and inflow of Atlantic Water (AW) the last decades that only recently have been observed in the Arctic Ocean north of ... -
Variability in the anatoxin gene clusters of Cuspidothrix issatschenkoi from Germany, New Zealand, China and Japan
(Journal article; Peer reviewed, 2018)Anatoxin-a and homoanatoxin-a are neurotoxic cyanotoxins produced by benthic and planktonic cyanobacteria worldwide. These toxins are produced by the cyanobacterial genera Dolichospermum, Cuspidothrix, Phormidium, Oscillatoria, ... -
Variability in the sxt Gene Clusters of PSP Toxin Producing Aphanizomenon gracile Strains from Norway, Spain, Germany and North America
(Journal article; Peer reviewed, 2016)Paralytic shellfish poisoning (PSP) toxin production has been detected worldwide in the cyanobacterial genera Anabaena, Lyngbya, Scytonema, Cuspidothrix and Aphanizomenon. In Europe Aphanizomenon gracile and Cuspidothrix ... -
Variation in Phenolic Chemistry in Zostera marina Seagrass Along Environmental Gradients
(Peer reviewed; Journal article, 2021)Chemical ecology has been suggested as a less time-consuming and more cost-efficient monitoring tool of seagrass ecosystems than traditional methods. Phenolic chemistry in Zostera marina samples was analyzed against latitude, ... -
Variation in population structure and standing stocks of kelp along multiple environmental gradients and implications for ecosystem services
(Peer reviewed; Journal article, 2021)There is an increasing focus on ecosystem services provided by macroalgae worldwide, many which depend on its structural and morphological characteristics. Here we investigated how characteristics of canopy kelp plants of ... -
