Distribution of non-native brook trout (Salvelinus fontinalis ) across Norwegian waterbodies – is it an invasive species?
(Journal article; Peer reviewed, 2018)Non-native brook trout (Salvelinus fontinalis MITCHILL, 1815) was introduced into Norway in 1883. However, it was not until the late 1970s that this acid-tolerant salmonid species was stocked into many acidified lakes that ... -
Distribution pattern of mercury in northern Barents Sea and Eurasian Basin surface sediment
(Peer reviewed; Journal article, 2022)Marine sediment is a significant sink for the global pollutant mercury. In a rapidly changing Arctic region, mercury (Hg) bioaccumulation in the marine ecosystem remains a prominent environmental issue. Here, we report ... -
Distribution, identification and range expansion of the common Asellidae in Northern Europe, featuring the first record of Proasellus meridianus in the Nordic countries
(Peer reviewed; Journal article, 2020)Two out of the three common Asellidae species in Northern Europe are increasing their ranges, aided by human activities. Here we report the discovery of Proasellus coxalis (Dollfuss 1892) in new areas in Norway and the ... -
Distribution, structure and function of Nordic eelgrass (Zostera marina) ecosystems: Implications for coastal management and conservation
(Journal article; Peer reviewed, 2014)1. This paper focuses on the marine foundation eelgrass species, Zostera marina, along a gradient from the northern Baltic Sea to the north-east Atlantic. This vast region supports a minimum of 1480km 2 eelgrass (maximum ... -
Diurnal variability of persistent organic pollutants in the atmosphere over the remote Southern Atlantic Ocean
(Journal article; Peer reviewed, 2014)A diel (24-h) cycle with daytime atmospheric concentrations higher than nighttime concentrations by a factor of 1.5–3 was observed for several low molecular weight polychlorinated biphenyls (PCBs) and polycyclic aromatic ... -
Diverse land use and the impact on (Irrigation) water quality and need for measures - A case study of a Norwegian river
(Journal article; Peer reviewed, 2015)Surface water is used for irrigation of food plants all over the World. Such water can be of variable hygienic quality, and can be contaminated from many different sources. The association of contaminated irrigation water ... -
Diversified Farming Systems: Impacts and Adaptive Responses to the COVID-19 Pandemic in the United States, Norway and China
(Peer reviewed; Journal article, 2022)The COVID-19 pandemic fully exposed the vulnerability of the global agri-food system to shocks and stresses, highlighting the need for transformation and action to make it more resilient and inclusive. This paper offers a ... -
Diversity of cyanobacteria and cyanotoxins in Hartbeespoort Dam, South Africa
(Journal article; Peer reviewed, 2014)The South African Hartbeespoort Dam is known for the occurrence of heavy Microcystis blooms. Although a few other cyanobacterial genera have been described, no detailed study on those cyanobacteria and their potential toxin ... -
DNA barcoding the genus Chara: Molecular evidence recovers fewer taxa than the classical morphological approach
(Journal article; Peer reviewed, 2015)Charophytes (Charales) are benthic algae with a complex morphology. They are vulnerable to ecosystem changes, such as eutrophication, and are red‐listed in many countries. Accurate identification of Chara species is critical ... -
DNA dispose, but subjects decide. Learning and the extended synthesis
(Journal article; Peer reviewed, 2015)Adaptation by means of natural selection depends on the ability of populations to maintain variation in heritable traits. According to the Modern Synthesis this variation is sustained by mutations and genetic drift. ... -
Do benthic algae provide important information over and above that provided by macrophytes and phytoplankton in lake status assessment? – Results from a case study in Norway
(Journal article; Peer reviewed, 2019)To test if phytobenthic algae provide additional important information to macrophytes and phytoplankton for lake monitoring, we sampled two large lakes in Norway. In each lake, we analyzed water chemistry and phytoplankton ... -
Do DOM quality and origin affect the uptake and accumulation of lipid-soluble contaminants in coastal filter feeders? An experimental simulation of teflubenzuron exposure to blue mussels
(Peer reviewed; Journal article, 2023)The increased export of terrestrial dissolved organic matter (terrDOM) to coastal marine ecosystems may affect local filter feeders and the local food web via the altered uptake of organic material and associated contaminants. ... -
Does sedation with AQUI-S® mitigate transport stress and post transport mortality in ballan wrasse (Labrus bergyltae)?
(Peer reviewed; Journal article, 2024)Ballan wrasse (Labrus bergylta) are commonly used as cleaner fish in salmon farms as a biological treatment to mitigate sea lice infestation. Improved welfare for cleaner fish both during production of these fish and when ... -
Dose-dependent hepatic transcriptional responses in Atlantic salmon (Salmo salar) exposed to sublethal doses of gamma radiation
(Journal article; Peer reviewed, 2014)Due to the production of free radicals, gamma radiation may pose a hazard to living organisms. The high-dose radiation effects have been extensively studied, whereas the ecotoxicity data on low-dose gamma radiation is still ... -
Drilling discharges reduce sediment reworking of two benthic species
(Journal article; Peer reviewed, 2017)Effects of water-based drill cuttings on sediment reworking activity were studied on two important benthic bioturbators (the bivalve Abra segmentum and the brittle star Amphiura filiformis) using thin aquaria, fluorescentdyed ... -
Drivers of Perceived Nuisance Growth by Aquatic Plants
(Peer reviewed; Journal article, 2023)Mass developments of macrophytes occur frequently worldwide and are often considered a nuisance when interfering with human activities. It is crucial to understand the drivers of this perception if we are to develop effective ... -
Drug Use by Music Festival Attendees: A Novel Triangulation Approach Using Self-Reported Data and Test Results of Oral Fluid and Pooled Urine Samples
(Journal article; Peer reviewed, 2019)Background: Self-reported data are commonly used when investigating illicit substance use. However, self-reports have well-known limitations such as limited recall and socially desirable responding. Mislabeling or adulteration ... -
Dual staining with CFDA-AM and SYTOX Blue in flow cytometry analysis of UV-irradiated Tetraselmis suecica to evaluate vitality
(Journal article; Peer reviewed, 2016)After disinfection of ballast water, it is crucial to detect organisms and determine their vitality to assess the performance of the chosen treatment technique. Ultraviolet (UV) irradiation is a treatment technology commonly ... -
Dying for change: A roadmap to refine the fish acute toxicity test after 40 years of applying a lethal endpoint
(Peer reviewed; Journal article, 2021)The fish acute toxicity test (TG203; OECD, 2019) is frequently used and highly embedded in hazard and risk assessment globally. The test estimates the concentration of a chemical that kills 50% of the fish (LC50) over a ... -
