Discards of cod (Gadus morhua) in the Norwegian coastal fisheries: improving past and future estimates
(Journal article; Peer reviewed, 2022)Discarding can be an unknown source of biases and uncertainties in stock assessments. Discarding patterns and quantities vary so a routine methodology for estimating discards is important to give a better picture of total ... -
Discovery of active off-axis hydrothermal vents at 9° 54′N East Pacific Rise
(Journal article; Peer reviewed, 2022)Comprehensive knowledge of the distribution of active hydrothermal vent fields along midocean ridges is essential to understanding global chemical and heat fluxes and endemic faunal distributions. However, current knowledge ... -
Discovery of Nuclear-Encoded Genes for the Neurotoxin Saxitoxin in Dinoflagellates
(Peer reviewed; Journal article, 2011-05-18)Saxitoxin is a potent neurotoxin that occurs in aquatic environments worldwide. Ingestion of vector species can lead to paralytic shellfish poisoning, a severe human illness that may lead to paralysis and death. In ... -
Disentangling effects and context dependencies of climate change on alpine plants
(Doctoral thesis, 2022-12-02)Klimaendringer byr på nye utfordringer for fjellplanter, og påvirker dem både direkte gjennom å endre fysiologiske prosesser, og indirekte gjennom endringer i interaksjoner mellom planter. Disse indirekte effektene kan ... -
Disentangling Obstacles to Knowledge Co-Production for Early-Career Researchers in the Marine Sciences
(Journal article; Peer reviewed, 2022)Knowledge co-production involving researchers and non-academic actors is becoming increasingly important for tackling sustainability issues. Coastal and marine social-ecological systems are one example where knowledge ... -
Disentangling the complexity of permafrost soil by using high resolution profiling of microbial community composition, key functions and respiration rates
(Peer reviewed; Journal article, 2018-12-13)Thawing permafrost can stimulate microbial activity, leading to faster decomposition of formerly preserved organic matter and CO2 release. Detailed knowledge about the vertical distribution of the responsible microbial ... -
Disentangling the effects of sex, life history and genetic background in Atlantic salmon: growth, heart and liver under common garden conditions
(Journal article; Peer reviewed, 2020)Livestock domestication has long been a part of agriculture, estimated to have first occurred approximately 10 000 years ago. Despite the plethora of traits studied, there is little understanding of the possible impacts ... -
Disintegration stability of extruded fish feed affects gastric functions in Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2021)In the present study, two salmon feeds with different disintegration stabilities were produced by impacting extruder viscous heat dissipation with the use of different lipid levels in the feed mix. The feeds were then dried ... -
Dispersal limitations matter for microbial morphospecies
(Peer reviewed; Journal article, 2006)In contrast with macroorganisms, whose geographical ranges are typically restricted, many microbial species appear to have cosmopolitan distributions. This observation has been explained as a consequence of ubiquitous ... -
Dispersal syndromes are poorly associated with climatic niche differences in the Azorean seed plants
(Journal article; Peer reviewed, 2021)Aim Environmental niche tracking is linked to the species ability to disperse. While well investigated on large spatial scales, dispersal constraints also influence small-scale processes and may explain the difference ... -
Dissecting the Transcriptional Regulatory Properties of Human Chromosome 16 Highly Conserved Non-Coding Regions
(Peer reviewed; Journal article, 2011-09-13)Non-coding DNA conservation across species has been often used as a predictor for transcriptional enhancer activity. However, only a few systematic analyses of the function of these highly conserved non-coding regions ... -
distantia: an open-source toolset to quantify dissimilarity between multivariate ecological time-series
(Peer reviewed; Journal article, 2020)There is a large array of methods to extract knowledge and perform ecological forecasting from ecological time‐series. However, in spite of its importance for data‐mining, pattern‐matching and ecological synthesis, methods ... -
Distinct genetic clustering in the weakly diferentiated polar cod, Boreogadus saida Lepechin, 1774 from East Siberian Sea to Svalbard
(Journal article; Peer reviewed, 2021)The cold-adapted polar cod Boreogadus saida, a key species in Arctic ecosystems, is vulnerable to global warming and ice retreat. In this study, 1257 individuals sampled in 17 locations within the latitudinal range of ... -
Distinguishing the roles of dispersal in diversity maintenance and in diversity limitation
(Peer reviewed; Journal article, 2005-07)In recent years, a considerable research effort has gone into studying how dispersal might affect the diversity of local communities. While this general topic has received attention from theoretical and empirical ecologists ... -
Distribution and autecology of chrysophyte cysts from high Arctic Svalbard lakes: preliminary evidence of recent environmental change
(Peer reviewed; Journal article, 2004)Chrysophycean stomatocyst assemblages were analysed from the sediments of 17 lakes and ponds from Svalbard as one component of a multi-proxy investigation of recent environmental change in the high Arctic. Sediment cores ... -
Distribution and spread of the invasive slug Arion vulgaris Moquin - Tandon in Norway
(Peer reviewed; Journal article, 2013)The present distribution of the invasive slug Arion vulgaris Moquin-Tandon was studied in Norway. This important pest species has spread to many parts of Europe during the last decades, inflicting damage to agriculture and ... -
Distribution and suitable habitat of the cold-water corals Lophelia pertusa, Paragorgia arborea, and Primnoa resedaeformis on the Norwegian continental shelf
(Journal article; Peer reviewed, 2020)Cold-water corals are habitat-forming species that are also classified as indicators of vulnerable marine ecosystems (VMEs) due to the threat of various anthropogenic impacts, e.g., fisheries and oil/mineral exploration. ... -
The Distribution of IgT mRNA+ Cells in the Gut of the Atlantic Salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2023)The newly discovered IgT+ B cell is thought to play a dominant role in mucosal immunity, but limited studies have examined its distribution in fish species, hindering our understanding of its function. This study investigated ... -
