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)
(Peer reviewed; Journal article, 2021) -
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
(Journal article; Peer reviewed, 2014) -
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 ... -
Towards sustainable management of kelp forests: An analysis of adaptive governance in developing regimes for wild kelp harvesting in Scotland and Norway
(Peer reviewed; Journal article, 2021)Kelp forests are highly productive habitats which support important marine species and ecosystem services including coastal protection and carbon storage. Demand is increasing for commercial products from wild and cultivated ... -
Toxicity of microplastics and natural particles in the freshwater dipteran Chironomus riparius: Same same but different?
(Peer reviewed; Journal article, 2020)Microplastics (MP) are contaminants of emerging concern in aquatic ecosystems. While the number of studies is rapidly increasing, a comparison of the toxicity of MP and natural particulate matter is largely missing. In ... -
Toxicity of organic compounds from unresolved complex mixtures (UCMs) to primary fish hepatocytes
(Journal article; Peer reviewed, 2017)Many environmental matrices contaminated with organic pollutants derived from crude oil or degraded petroleum contain mixtures so complex that they are typically unresolved by conventional analytical techniques such as gas ... -
Traditional Dimensions of Seabed Resource Management in the Context of Deep Sea Mining in the Pacific: Learning From the Socio-Ecological Interconnectivity Between Island Communities and the Ocean Realm
(Peer reviewed; Journal article, 2021)In many of the Pacific Islands, local communities have long-held cultural and spiritual attachments to the sea, in particular to species and specific marine areas, processes, habitats, islands, and natural seabed formations. ... -
Trait‐based ecology at large scales: Assessing functional trait correlations, phylogenetic constraints and spatial variability using open data
(Peer reviewed; Journal article, 2020)The growing use of functional traits in ecological research has brought new insights into biodiversity responses to global environmental change. However, further progress depends on overcoming three major challenges involving ...
