The influence of a submerged meadow on uptake and trophic transfer of legacy mercury from contaminated sediment in the food web in a brackish Norwegian fjord
(Journal article; Peer reviewed, 2019)There are contradicting results on the importance of legacy mercury (Hg) contaminated sediments to Hg fish tissue concentrations. Still, sediment remediation actions often aim at minimizing ecosystem exposure and human ... -
The influence of permanently submerged macrophytes on sediment mercury distribution, mobility and methylation potential in a brackish Norwegian fjord
(Journal article; Peer reviewed, 2018)Macrophytes are shown to affect the microbial activity in different aqueous environments, with an altering of the sediment cycling of mercury (Hg) as a potential effect. Here, we investigated how a meadow with permanently ... -
The influence of physical factors on kelp and sea urchin distribution in previously and still grazed areas in the NE Atlantic
(Journal article; Peer reviewed, 2014)The spatial distribution of kelp (Laminaria hyperborea) and sea urchins (Strongylocentrotus droebachiensis) in the NE Atlantic are highly related to physical factors and to temporal changes in temperature. On a large scale, ... -
The INtegrated CAtchment model of phosphorus dynamics (INCA-P): Description and demonstration of new model structure and equations
(Journal article; Peer reviewed, 2016)INCA-P is a dynamic, catchment-scale phosphorus model which has been widely applied during the last decade. Since its original release in 2002, the model structure and equations have been significantly altered during several ... -
The kelp cultivation potential in coastal and offshore regions of Norway
(Journal article; Peer reviewed, 2019)We have evaluated the cultivation potential of sugar kelp (Saccharina latissima) as a function of latitude and position (near- and offshore) along the Norwegian coast using a coupled 3D hydrodynamic-biogeochemical-kelp ... -
The major threats to Atlantic salmon in Norway
(Journal article; Peer reviewed, 2017)Atlantic salmon (Salmo salar) is an economically and culturally important species. Norway has more than 400 watercourses with Atlantic salmon and supports a large proportion of the world’s wild Atlantic salmon. Atlantic ... -
The occurrence and spread of Gonyostomum semen (Ehr.) Diesing (Raphidophyceae) in Norwegian lakes
(Journal article; Peer reviewed, 2014)The invasive and nuisance microalga Gonyostomum semen has recently expanded its geographical distribution and increased its biomass in Sweden and Finland. Temperatures, total organic carbon (TOC), water colour and phosphorous ... -
The organic pollutant status of rivers in Bosnia and Herzegovina as determined by a combination of active and passive sampling methods
(Journal article; Peer reviewed, 2018)There is an overall lack of data concerning the pollution status of Bosnia Herzegovina, which is confounded by fragmented national environmental management. The present study aimed to provide some initial data for ... -
The role of charophytes (Charales) in past and present environments: An overview
(Journal article; Peer reviewed, 2015)Charophytes, i.e. extant and fossil members of the order Charales plus the members of the extinct orders Sycidiales and Moellerinales, are closely related to modern land plants. These algae have a complex morphology, and ... -
The Suitability of the Ecosystem Services Framework for Guiding Benefit Assessments in Human-Modified Landscapes Exemplified by Regulated Watersheds—Implications for a Sustainable Approach
(Journal article; Peer reviewed, 2019)To support decision-making, benefit assessments have become an obligatory part of natural resource management. In this context, the ecosystem services (ES) framework has been widely adopted for identifying and assessing ... -
The “Forgotten” Ecology Behind Ecological Status Evaluation: Re-Assessing the Roles of Aquatic Plants and Benthic Algae in Ecosystem Functioning
(Journal article; Peer reviewed, 2016)Aquatic plants and benthic algae have long been used as indicators for nutrient enrichment in lakes and streams. Evaluations of the performance of indices calculated from species assemblages of aquatic plants and algae are ... -
Three decades of change in the Skagerrak coastal ecosystem, shaped by eutrophication and coastal darkening
(Peer reviewed; Journal article, 2023)Global coastal ecosystems are under accelerating pressure from human activities and climate change. In this study we explore a long-term time series (mostly 1990–2016) from major Norwegian rivers, together with coastal ... -
Tidal Energy Loss, Internal Tide Radiation, and Local Dissipation for Two-Layer Tidal Flow over a Sill
(Journal article; Peer reviewed, 2017)A simple analytical model for tidal energy loss at fjord sills and its partitioning into local dissipation and radiated internal tides is presented. The analytical model builds on a two-layer assumption with quasi-steady ... -
Toniniopsis bartakii-a new species of lichenised fungus from James Ross Island (Antarctic Peninsula)

Tools and constraints in monitoring interactions between marine litter and megafauna: Insights from case studies around the world
(Journal article; Peer reviewed, 2019)Adverse impacts of marine litter is documented on >1400 species, including marine megafauna (fish, birds, sea turtles and mammals). The primary impacts include ingestion and entanglement, and there is increasing concern ... -
Top-down release of mesopredatory fish is a weaker structuring driver of temperate rocky shore communities than bottom-up nutrient enrichment
(Peer reviewed; Journal article, 2020)Ecological impacts of top-down trophic cascades in combination with bottom-up nutrient enrichment are increasingly being reported. Such effects may be triggered by decline in the abundance and size of piscivore fish leading ... -
Top-down versus bottom-up project appraisal processes, and external review. Evidence from Norway and China
(Peer reviewed; Journal article, 2013)Project appraisal plays an important role in choosing the right project and is crucial for the success of public investment projects. Different factors may affect the choice of appraisal process in different countries. By ... -
Towards a comprehensive and realistic risk evaluation of engineered nanomaterials in the urban water cycle

Towards a future without stocking: harvest and river regulation determine long-term population viability of migratory salmonids
(Peer reviewed; Journal article, 2021)Freshwater species are particularly vulnerable to emerging threats linked to climate change because they are often already heavily impacted by habitat destruction, pollution, and exploitation. For many harvested populations ...
