Towards more culturally aware teaching of ‘scientific practices’: Understanding science as a social-historical human endeavour
(Peer reviewed; Journal article, 2024)‘Scientific practices’ are included as a core element in Norway’s new science curriculum as of 2020. In dialogue with international research on the teaching and learning of scientific practices, Haug et al. (2021) have ... -
Higher vitamin B12 levels in neurodevelopmental disorders than in healthy controls and schizophrenia A comparison among participants between 2 and 53 years
(Peer reviewed; Journal article, 2020)Recent studies suggest that both high and low levels of vitamin B12 (vitB12) may have negative health impacts. We measured VitB12 in patients with the Neurodevelopmental disorders (ND) (n = 222), comprised of Autism Spectrum ... -
Exploring freshwater challenges for conservation efforts : Insights into threatened and invasive fish species using environmental DNA
(Doctoral dissertations at University of Agder; no. 490, Doctoral thesis, 2024)Ferskvannsøkosystemer trues av habitatendringer, menneskeskapte barrierer, fremmede arter, forurensning, overfiske og klimaendringer. Selv om internasjonale lover og forskrifter støtter bevaring, kreves det fortsatt betydelig ... -
Personality of sea trout : A case study on ecology, conservation and dynamics in coastal Skagerrak
(Doctoral dissertations at University of Agder;no. 228, Doctoral thesis, 2019)Variation in fish behaviour seems to be an important part of species’ lifehistory and adaptation to environmental change. Interestingly, variation occurs not only in response to environmental cues, but can also be consistently ... -
Seascape ecology of Atlantic cod (Gadus morhua) in coastal Skagerrak: population structure, connectivity, and role in fish assemblage
(Doctoral dissertations at University of Agder;no. 294, Doctoral thesis, 2020)Atlantic cod populations along the Norwegian Skagerrak coast consist of two known ecotypes. During the last decade, there has been a dramatic decline of larger cod and other piscivorous fish species in eastern Skagerrak. ... -
Seasonality in phytoplankton communities and production in three Arctic fjords across a climate gradient
(Peer reviewed; Journal article, 2024)Phytoplankton communities and production in Arctic fjords undergo strong seasonal variations. Phytoplankton blooms are periods with high primary production, leading to elevated algal biomass fueling higher trophic levels. ... -
Effect of environmental drivers on the spatiotemporal distribution of mackerel at age in the Nordic Seas during 2010-20
(Peer reviewed; Journal article, 2024)A joint spatio–temporal distribution model of mackerel (ages 3–10) was developed to investigate the age-based responses of mackerel to three environmental drivers: sea surface temperature (SST), mixed layer depth, and ... -
Diatom-mediated food web functioning under ocean artificial upwelling
(Peer reviewed; Journal article, 2024)Enhancing ocean productivity by artificial upwelling is evaluated as a nature-based solution for food security and climate change mitigation. Fish production is intended through diatom-based plankton food webs as these are ... -
Stakeholders' perception and willingness-to-pay for an aquaculture-based fisheries enhancement program for coastal cod in Southern Norway
(Peer reviewed; Journal article, 2024)The coastal cod fishery in Southern Norway has experienced a significant decline over the last decades. Recreational fishing for cod in the eastern part of the country is currently banned. Fisheries managers have adopted ... -
Organic carbon export by marine mammal deadfalls in the Nordic Seas
(Master thesis, 2024)The biological pump is a critical process in the oceanic carbon cycle, transferring organic carbon from the atmosphere and surface waters into the deep ocean and seafloor sediments. Organic carbon stored in living biomass ... -
Passive acoustic monitoring of cetaceans in the Norwegian Skagerrak
(Master thesis, 2024)Marine ecosystems have been under pressure for decades as a result of intensive human activity. Cetaceans have also been negatively affected by our actions, so to implement protection and conservation plans, it is crucial ... -
Insights into lobster trap selectivity: exploring the role of local demography and behaviour for effective reserve monitoring
(Master thesis, 2024)Human activities have a major effect on the world’s ecosystems including the marine environment, where harvesting practices often target individuals based on specific traits, resulting in selective fishing. This selective ... -
Assessing the cleanup efforts at the historically polluted site in the Port of Liepaja, Karosta Channel.
(Master thesis, 2024)The presence of persistent contaminants in the sediments, such as heavy metals and hydrocarbons, can have long-lasting negative effects on marine ecosystems, resulting in harming both wildlife and humanity. It is critical ... -
Evaluation of mitigation measures for Atlantic salmon and brown trout at hydropower plants and their prospect as selective agents
(Doctoral dissertations at University of Agder;no. 314, Doctoral thesis, 2021)Renewable energy contributes towards the world`s growing energy demands and urgent need for mitigating climate change. However, these renewable sources of energy may have localized, detrimental environmental effects. For ... -
Atmospheric brightening counteracts warming-induced delays in autumn phenology of temperate trees in Europe
(Peer reviewed; Journal article, 2021)Aim Ongoing climate warming has been widely reported to delay autumn phenology, which in turn impacts carbon, water, energy and nutrient balances at regional and global scales. However, the underlying mechanisms of autumn ... -
Incidence of persistent contaminants through blue mussels biomonitoring from Flekkefjord fjord and their relevance to food safety
(Peer reviewed; Journal article, 2020)Dredging activities can lead to the re-suspension of contaminated sediments, resulting in a potential hazard for the whole ecosystem and also for human health. Six-month active biomonitoring was performed in order to monitor ... -
Battle of the borders: Is a range-extending fiddler crab affecting the spatial niche of a congener species?
(Peer reviewed; Journal article, 2020)Climate change is drastically altering environmental conditions and resource availability. Many organisms are shifting their distribution boundaries. Fiddler crabs, for instance, are important ecosystem engineers in coastal ... -
Drivers of spatial and temporal micro- and mesozooplankton dynamics in an estuary under strong anthropogenic influences (The Eastern Scheldt, Netherlands)
(Peer reviewed; Journal article, 2023)The Eastern Scheldt estuary in the Netherlands has been anthropogenically changed by the construction of a storm surge barrier about 30 years ago, affecting abiotic conditions as well as phytoplankton and zooplankton (ZP). ... -
Respiration rate scales inversely with sinking speed of settling marine aggregates
(Peer reviewed; Journal article, 2023)Sinking marine aggregates have been studied for a long time to understand their role in carbon sequestration. Traditionally, sinking speed and respiration rates have been treated as independent variables, but two recent ... -
Hazard and catch composition of ghost fishing gear revealed by a citizen science clean-up initiative
(Peer reviewed; Journal article, 2022)Ghost fishing, the continued catch of fishes and invertebrates by lost fishing gear, represents an animal welfare issue as well as a waste of both potential food and ecosystem resources. Fishing gear is lost by both ...
