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 ... -
Distribution pattern of mercury in northern Barents Sea and Eurasian Basin surface sediment
(Peer reviewed; Journal article, 2022)Marine sediment is a significant sink for the global pollutant mercury. In a rapidly changing Arctic region, mercury (Hg) bioaccumulation in the marine ecosystem remains a prominent environmental issue. Here, we report ... -
Distribution, identification and range expansion of the common Asellidae in Northern Europe, featuring the first record of Proasellus meridianus in the Nordic countries
(Peer reviewed; Journal article, 2020)Two out of the three common Asellidae species in Northern Europe are increasing their ranges, aided by human activities. Here we report the discovery of Proasellus coxalis (Dollfuss 1892) in new areas in Norway and the ... -
Distribution, structure and function of Nordic eelgrass (Zostera marina) ecosystems: Implications for coastal management and conservation
(Journal article; Peer reviewed, 2014)1. This paper focuses on the marine foundation eelgrass species, Zostera marina, along a gradient from the northern Baltic Sea to the north-east Atlantic. This vast region supports a minimum of 1480km 2 eelgrass (maximum ... -
Diverse land use and the impact on (Irrigation) water quality and need for measures - A case study of a Norwegian river
(Journal article; Peer reviewed, 2015)Surface water is used for irrigation of food plants all over the World. Such water can be of variable hygienic quality, and can be contaminated from many different sources. The association of contaminated irrigation water ... -
Diversified Farming Systems: Impacts and Adaptive Responses to the COVID-19 Pandemic in the United States, Norway and China
(Peer reviewed; Journal article, 2022)The COVID-19 pandemic fully exposed the vulnerability of the global agri-food system to shocks and stresses, highlighting the need for transformation and action to make it more resilient and inclusive. This paper offers a ... -
DNA barcoding the genus Chara: Molecular evidence recovers fewer taxa than the classical morphological approach
(Journal article; Peer reviewed, 2015)Charophytes (Charales) are benthic algae with a complex morphology. They are vulnerable to ecosystem changes, such as eutrophication, and are red‐listed in many countries. Accurate identification of Chara species is critical ... -
DNA dispose, but subjects decide. Learning and the extended synthesis
(Journal article; Peer reviewed, 2015)Adaptation by means of natural selection depends on the ability of populations to maintain variation in heritable traits. According to the Modern Synthesis this variation is sustained by mutations and genetic drift. ... -
Do benthic algae provide important information over and above that provided by macrophytes and phytoplankton in lake status assessment? – Results from a case study in Norway
(Journal article; Peer reviewed, 2019)To test if phytobenthic algae provide additional important information to macrophytes and phytoplankton for lake monitoring, we sampled two large lakes in Norway. In each lake, we analyzed water chemistry and phytoplankton ... -
Do DOM quality and origin affect the uptake and accumulation of lipid-soluble contaminants in coastal filter feeders? An experimental simulation of teflubenzuron exposure to blue mussels
(Peer reviewed; Journal article, 2023)The increased export of terrestrial dissolved organic matter (terrDOM) to coastal marine ecosystems may affect local filter feeders and the local food web via the altered uptake of organic material and associated contaminants. ... -
Does sedation with AQUI-S® mitigate transport stress and post transport mortality in ballan wrasse (Labrus bergyltae)?
(Peer reviewed; Journal article, 2024)Ballan wrasse (Labrus bergylta) are commonly used as cleaner fish in salmon farms as a biological treatment to mitigate sea lice infestation. Improved welfare for cleaner fish both during production of these fish and when ... -
Dose-dependent hepatic transcriptional responses in Atlantic salmon (Salmo salar) exposed to sublethal doses of gamma radiation
(Journal article; Peer reviewed, 2014)Due to the production of free radicals, gamma radiation may pose a hazard to living organisms. The high-dose radiation effects have been extensively studied, whereas the ecotoxicity data on low-dose gamma radiation is still ... -
