Seasonal variation of mercury and δ15N in fish from Lake Heddalsvatn, southern Norway
(Peer reviewed; Journal article, 2014)Seasonal variations of mercury (Hg) concentration in muscle tissue of northern pike (Esox lucius L), European whitefish (Coregonus lavaretus L) and European perch (Perca fluviatilis L) have been investigated in Lake ... -
Seasonality in land–ocean connectivity and local processes control sediment bacterial community structure and function in a High Arctic tidal flat
(Peer reviewed; Journal article, 2023)Climate change is altering patterns of precipitation, cryosphere thaw, and land–ocean influxes, affecting understudied Arctic estuarine tidal flats. These transitional zones between terrestrial and marine systems are ... -
Seaweed forests are carbon sinks that may help mitigate CO2 emissions: a comment on Gallagher et al. (2022)
(Peer reviewed; Journal article, 2023)Recently, Gallagher et al. (2022) suggested that seaweed ecosystems are net heterotrophic carbon sources due to CO2 released from the consumption of external subsidies. Here we outline several flaws in their argument, which ... -
Secchi depth in the Oslofjord-Skagerrak area: theory, experiments and relationships to other quantities
(Journal article; Peer reviewed, 2014)The Secchi depth and its relationships to other properties of the sea water in the Oslofjord–Skagerrak area have been investigated. White and black disks of different sizes have been applied, and the Secchi depth has been ... -
Sediment toxicity assessment using zebrafish (Danio rerio) as a model system: Historical review, research gaps and trends
(Peer reviewed; Journal article, 2021)Sediment is an important compartment in aquatic environments and acts as a sink for environmental pollutants. Sediment toxicity tests have been suggested as critical components in environmental risk assessment. Since the ... -
Selection of indicator contaminants of emerging concern when reusing reclaimed water for irrigation — A proposed methodology
(Peer reviewed; Journal article, 2023)Organic and microbial contaminants of emerging concern (CECs), even though not yet regulated, are of great concern in reclaimed water reuse projects. Due to the large number of CECs and their different characteristics, it ... -
Selection of the optimal extraction protocol to investigate the interaction between trace elements and environmental plastic
(Peer reviewed; Journal article, 2023)The interaction between environmental plastic and trace elements is an issue of concern. Understanding their interaction mechanisms is key to evaluate the potential threats for the environment. To this regard, consolidating ... -
Self Adjusting Algorithm for the Nontargeted Feature Detection of High Resolution Mass Spectrometry Coupled with Liquid Chromatography Profile Data
(Journal article; Peer reviewed, 2019)Nontargeted feature detection in data from high resolution mass spectrometry is a challenging task, due to the complex and noisy nature of data sets. Numerous feature detection and preprocessing strategies have been developed ... -
Self-reports of consumption of amphetamines, cocaine and heroin in a survey among marginalized drug users
(Journal article, 2014)Scientific literature offers few measurements of the quantities consumed by individual drug users. Such measurements are used for calculating the total drug consumption by the quantity-frequency method, and are extremely ... -
Sensitivity of modelled North Sea cod larvae transport to vertical behaviour, ocean model resolution and interannual variation in ocean dynamic
(Journal article; Peer reviewed, 2018)Transport with ocean currents affects the spatial distribution and survival of fish eggs and larvae and thereby population connectivity. Biophysical models are commonly used to understand these dynamics. Advancements such ... -
The sensitivity of primary productivity in Disko Bay, a coastal Arctic ecosystem, to changes in freshwater discharge and sea ice cover
(Peer reviewed; Journal article, 2023)The Greenland ice sheet is melting, and the rate of ice loss has increased 6-fold since the 1980s. At the same time, the Arctic sea ice extent is decreasing. Meltwater runoff and sea ice reduction both influence light and ... -
Sensitivity of the green algae Chlamydomonas reinhardtii to gamma radiation: Photosynthetic performance and ROS formation
(Journal article; Peer reviewed, 2017)The aquatic environment is continuously exposed to ionizing radiation from both natural and anthropogenic sources, making the characterization of ecological and health risks associated with radiation of large importance. ... -
Shifted dynamics of plankton communities in a restored lake: exploring the effects of climate change on phenology through four decades
(Peer reviewed; Journal article, 2022)Lake surface temperatures have increased globally in recent decades. Climate change can affect lake biota directly via enhanced water temperatures, shorter ice cover duration and prolonged stratification, and indirectly ... -
Shifts between sugar kelp and turf algae in Norway: regime shifts or flips between different opportunistic seaweed species?
(Journal article; Peer reviewed, 2019)Around year 2000, sugar kelp (Saccharina latissima) forests were observed to disappear in southern parts of Norway, being replaced by mats of turf algae (i.e. filamentous ephemeral algae) loaded with sediments. About 80% ... -
Shifts in flood generation processes exacerbate regional flood anomalies in Europe
(Peer reviewed; Journal article, 2023)Anomalies in the frequency of river floods, i.e., flood-rich or -poor periods, cause biases in flood risk estimates and thus make climate adaptation measures less efficient. While observations have recently confirmed the ... -
Short-term effects of macrophyte removal on aquatic biodiversity in rivers and lakes
(Peer reviewed; Journal article, 2022)Mass development of macrophytes is an increasing problem in many aquatic systems worldwide. Dense mats of macrophytes can negatively affect activities like boating, fishing or hydropower production and one of the management ... -
Short-term effects of macrophyte removal on emission of CO2 and CH4 in shallow lakes
(Peer reviewed; Journal article, 2022)Mass development of macrophytes in freshwater ecosystems is today considered a worldwide problem and substantial resources are spent on macrophyte removal each year. By removing the dominant primary producer, however, this ... -
Short-term rainfall limits cyanobacterial bloom formation in a shallow eutrophic subtropical urban reservoir in warm season
(Peer reviewed; Journal article, 2022)The global increase in dominance of toxic blooms of cyanobacteria has severely impacted aquatic ecosystems and threatened human health for decades. Although it has been shown that high levels of rainfall may inhibit the ... -
Short-term temporal variation of coastal marine eDNA
(Peer reviewed; Journal article, 2022)Temporal variation in eDNA signals is increasingly explored for understanding community ecology in aquatic habitats. Seasonal changes have been addressed using eDNA sampling, but very little is known regarding short-term ... -
