Diel and seasonal movements of the critically endangered European eel
(Journal article; Peer reviewed, 2013)The critically endangered European eel is declining throughout its range and more information on which to base management plans is necessary. Here we present data collected by electrofishing and PIT telemetry on the habitat ... -
Diel migration pattern of Atlantic salmon (Salmo salar) and sea trout (Salmo trutta) smolts: an assessment of environmental cues
(Journal article; Peer reviewed, 2017)The timing of smolt migration is a key phenological trait with profound implications for individual survival during both river descent and the subsequent sea sojourn of anadromous fish. We studied relationships between the ... -
Dietary l-tryptophan leaves a lasting impression on the brain and the stress response
(Journal article; Peer reviewed, 2017)Comparative models suggest that effects of dietary tryptophan (Trp) on brain serotonin (5-hydroxytryptamine; 5-HT) neurochemistry and stress responsiveness are present throughout the vertebrate lineage. Moreover, hypothalamic ... -
Differences in copper bioaccumulation and biological responses in three Mytilus species
(Journal article; Peer reviewed, 2015)Mytilus species are important organisms in marine systems being highly abundant and widely distributed along the coast of Europe and worldwide. They are typically used in biological effects studies and have a suite of ... -
Differences in the Fate of Surface and Subsurface Microplastics: A Case Study in the Central Atlantic
(Peer reviewed; Journal article, 2023)Plastic is recognized as a threat to marine ecosystems, and estimating the level of plastic and microplastics (MPs) pollution of the World Ocean is, nowadays, the goal of many studies. However, the use of different methods ... -
Differences in Trophic Level, Contaminant Load, and DNA Damage in an Urban and a Remote Herring Gull (Larus argentatus) Breeding Colony in Coastal Norway
(Peer reviewed; Journal article, 2022)Herring gulls (Larus argentatus) are opportunistic feeders, resulting in contaminant exposure depending on area and habitat. We compared contaminant concentrations and dietary markers between two herring gull breeding ... -
Digital Data Help Explain Drivers of Angler Satisfaction: An Example from Southern Norway
(Peer reviewed; Journal article, 2022)We analyzed trip-level self-reports collected by a cell phone app to understand angler satisfaction of fishing for sea trout Salmo trutta (anadromous Brown Trout) in southern Norway. We found no clear support for a positive ... -
Dimensions of transboundary legal coherence needed to foster ecosystem-based governance in the Arctic
(Journal article; Peer reviewed, 2019)The Arctic is a complex geographical area to govern sustainably due to strong geopolitical and socio-economic interests, high ecological vulnerability and importance, and significant legal and institutional fragmentation. ... -
Disappearing Blue Mussels – Can Mesopredators Be Blamed?
(Peer reviewed; Journal article, 2020)Despite many theories, the recent evident decreases in blue mussel (Mytilus edulis) abundance in southern Norway and western Sweden (eastern North Sea) have not yet been explained. To test the possible role of increased ... -
Disinfection by-products and ecotoxicity of ballast water after oxidative treatment – Results and experiences from seven years of full-scale testing of ballast water management systems
(Journal article; Peer reviewed, 2013)Since 2005, five different ballast water management systems (BWMS) based on chlorination treatment have been tested by Norwegian Institute for Water Research (NIVA) according to guidelines from the International Maritime ... -
Dispersal and Deposition of Detritus From Kelp Cultivation
(Peer reviewed; Journal article, 2022)A high resolution coastal and ocean hydrodynamic model system was used to investigate the transport and deposition patterns of Particulate Organic Matter (POM) from kelp farmed at three locations of different properties: ... -
Dissolved methane in the residual basins of the Aral Sea
(Peer reviewed; Journal article, 2019)Due to catastrophic desiccation, today's Aral Sea consists of a few separate residual basins, characterized by different ecological conditions (the Large Aral, Lake Tshchebas, the Small Aral). This study is the first report ... -
Distinct Seasonal Primary Production Patterns in the Sub-Polar Gyre and Surrounding Seas
(Peer reviewed; Journal article, 2021)Primary production (PP) in the sub-polar region appears to be important for ocean carbon uptake but how the different water masses contribute to the PP occurring here has not yet been described. Using two models based on ... -
Distinguishing between Sources of Natural Dissolved Organic Matter (DOM) Based on Its Characteristics
(Peer reviewed; Journal article, 2023)Increasing levels of dissolved organic matter (DOM) in watercourses in the northern hemisphere are mainly due to reduced acid rain, climate change, and changes in agricultural practices. However, their impacts vary in time ... -
Distribution and abundance of phytobenthic communities: Implications for connectivity and ecosystem functioning in a Black Sea Marine Protected Area
(Journal article; Peer reviewed, 2018)The distribution and abundance of macroalgal communities in a Marine Protected Area (MPA) along the Bulgarian Black Sea coast were mapped and quantified, with particular focus on the previously unstudied P. crispa ... -
Distribution and abundance of the invasive seagrass Halophila stipulacea and associated benthic macrofauna in Carriacou, Grenadines, Eastern Caribbean
(Journal article; Peer reviewed, 2018)The invasive seagrass Halophila stipulacea has spread throughout the eastern Caribbean since it was first recorded in Grenada in 2002. We quantified the distribution and abundance of H. stipulacea, and its associated ... -
Distribution of floating marine macro-litter in relation to oceanographic characteristics in the Russian Arctic Seas
(Peer reviewed; Journal article, 2021)The main objectives of this work were the acquisition of new data on floating marine macro litter (FMML) and natural floating objects in the Arctic seas, an initial assessment of the level of pollution by FMML and an ... -
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 ... -
