Calculating expected effects of treatment effectivity and river flow rates on the contribution of WWTP effluent to the ARG load of a receiving river
(Peer reviewed; Journal article, 2021)Concentrations of genetic markers for antibiotic resistance genes (ARGs) were measured in the effluents of three Norwegian wastewater treatment plants (WWTPs) and in a receiving river upstream and downstream of the discharge ... -
Can benthic foraminifera serve as proxies for changes in benthic macrofaunal community structure? Implications for the definition of reference conditions
(Journal article; Peer reviewed, 2018)Benthic macrofauna is one of the most widely used biological groups to assess the ecological status of marine systems. Lately, attention has been paid to similar use of benthic foraminifera. In this study, distribution ... -
Can current moisture responses predict soil CO2 efflux under altered precipitation regimes? A synthesis of manipulation experiments
(Journal article; Peer reviewed, 2014)As a key component of the carbon cycle, soil CO2 efflux (SCE) is being increasingly studied to improve our mechanistic understanding of this important carbon flux. Predicting ecosystem responses to climate change often ... -
Can improved nutrition for Atlantic salmon in freshwater increase fish robustness, survival and growth after seawater transfer?
(Peer reviewed; Journal article, 2021)The loss of fish in the seawater (SW) phase of Atlantic salmon farming is high, and a major proportion of this loss occurs in the period just after SW transfer. In the current study, we hypothesize that improvements made ... -
Can multitrophic interactions and ocean warming influence large-scale kelp recovery?
(Journal article; Peer reviewed, 2019)Ongoing changes along the northeastern Atlantic coastline provide an opportunity to explore the influence of climate change and multitrophic interactions on the recovery of kelp. Here, vast areas of sea urchin‐dominated ... -
Can plastic related chemicals be indicators of plastic ingestion in an Arctic seabird?
(Peer reviewed; Journal article, 2024)For decades, the northern fulmar (Fulmarus glacialis) has been found to ingest and accumulate high loads of plastic due to its feeding ecology and digestive tract morphology. Plastic ingestion can lead to both physical and ... -
Can sea urchin grazing of kelp forests in the arctic make rocky shore systems more vulnerable to oil spills?
(Journal article; Peer reviewed, 2019)In Arctic Norway, the risk of major marine oil spills associated with increasing offshore drilling, land terminal, and maritime transport activities is a cause for concern. Intertidal and subtidal kelp and seaweed communities ... -
Carbon export is facilitated by sea urchins transforming kelp detritus
(Peer reviewed; Journal article, 2019)With the increasing imperative for societies to act to curb climate change by increasing carbon stores and sinks, it has become critical to understand how organic carbon is produced, released, transformed, transported, and ... -
Carotenoid glycoside isolated and identified from cyanobacterium Cylindrospermopsis raciborskii
(Journal article; Peer reviewed, 2018)The freshwater cyanobacterium Cylindrospermopsis raciborskii was investigated for carotenoid composition. Besides β-carotene, echinenone and (9/9′Z)-echinenone a carotenoid glycoside was found to be the main component. ... -
Cascading effects of mass mortality events in Arctic marine communities
(Journal article; Peer reviewed, 2017)Mass mortality events caused by pulse anthropogenic or environmental perturbations (e.g., extreme weather, toxic spills or epizootics) severely reduce the abundance of a population in a short time. The frequency and impact ... -
A case of anisotropic exchange of non-polar chemicals with absorption-based passive samplers in water
(Peer reviewed; Journal article, 2019)Passive sampling is a powerful technique for the sampling hydrophobic organic contaminants present at trace level in water. A robust application of performance reference compounds (PRCs) for the estimation of in situ ... -
Catchment properties and the photosynthetic trait composition of freshwater plant communities
(Peer reviewed; Journal article, 2019)Unlike in land plants, photosynthesis in many aquatic plants relies on bicarbonate in addition to carbon dioxide (CO2) to compensate for the low diffusivity and potential depletion of CO2 in water. Concentrations of ... -
Caught in the middle: bottom‑up and top‑down processes impacting recruitment in a small pelagic fsh
(Journal article; Peer reviewed, 2022)Understanding the drivers behind fluctuations in fish populations remains a key objective in fishery science. Our predictive capacity to explain these fluctuations is still relatively low, due to the amalgam of interacting ... -
CDOM absorption properties of natural water bodies along extreme environmental gradients
(Journal article; Peer reviewed, 2019)We present absorption properties of colored dissolved organic matter (CDOM) sampled in six different water bodies along extreme altitudinal, latitudinal, and trophic state gradients. Three sites are in Norway: the mesotrophic ... -
The challenges of opportunistic sampling when comparing prevalence of plastics in diving seabirds: A multi-species example from Norway
(Peer reviewed; Journal article, 2024)There is a need for baseline information about how much plastics are ingested by wildlife and potential negative consequences thereof. We analysed the frequency of occurrence (FO) of plastics >1 mm in the stomachs of five ... -
Challenges with Quantifying Tire Road Wear Particles: Recognizing the Need for Further Refinement of the ISO Technical Specification
(Peer reviewed; Journal article, 2021)Environmental monitoring data for tire road wear particles are vastly limited compared to those for other microplastics, primarily due to analytical challenges with quantification. Recently, two ISO technical specifications ... -
Changes in drug use in European cities during early COVID-19 lockdowns – A snapshot from wastewater analysis
(Peer reviewed; Journal article, 2021)The COVID-19 outbreak has forced countries to introduce severe restrictive measures to contain its spread. In particular, physical distancing and restriction of movement have had important consequences on human behaviour ... -
Changes in microbial water quality in RAS following altered feed loading
(Journal article; Peer reviewed, 2018)Intensive recirculating aquaculture systems (RAS) with its hyper-eutrophic water offer ideal conditions for bacterial growth, abundance and activity, potentially affecting fish and system performance. Feed composition and ... -
Changes in phytoplankton community structure over a century in relation to environmental factors
(Peer reviewed; Journal article, 2022)Changes in phytoplankton abundance and biomass during the period 1933–2020 were examined by statistical modeling using data from the Inner Oslofjorden phytoplankton database. The phytoplankton abundances increased with ... -
