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 ... -
The discovery of the Younger Dryas, and comments on the current meaning and usage of the term
(Journal article; Peer reviewed, 2021)The Younger Dryas (YD) cold event was discovered in Denmark by Hartz and Mithers in 1904 and the term coined by Hartz in 1912. It was identified as a lacustrine clay bed containing plant macrofossils of an Arctic flora, ... -
Discrete Approximations of BV solutions to Doubly Nonlinear Degenerate Parabolic Equations

Discriminating between surfaces of peripheral membrane proteins and reference proteins using machine learning algorithms
(Master thesis, 2019-04-05)In biology, the cell membrane is an important component of a cell and usually works as a “fence” to distinguish the inside and outside of a cell. The key role is to protect the cells from being interfered by their surroundings ... -
Discrimination of n-3 Rich Oils by Gas Chromatography
(Peer reviewed; Journal article, 2010-11-22)Exploring the capabilities of instrumental techniques for discriminating n-3 rich oils derived from animals is a very important though much neglected area that was emphasized more than 100 years ago. In this study the ... -
A discussion on turbulent and undular bores using the models from the shallow water equations and the dispersive system.
(Master thesis, 2010-05-26)The bore is a wave phenomenon that occurs in channels and rivers of shallow water. Referred to as a discharge wave, a bore is generated by a sudden increase of water flow. Bores appear in certain rivers as the tide pushes ... -
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 genetic and epigenetic determinants of ultrafast adaptation
(Peer reviewed; Journal article, 2016)A major rationale for the advocacy of epigenetically mediated adaptive responses is that they facilitate faster adaptation to environmental challenges. This motivated us to develop a theoretical–experimental framework for ... -
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 rock record bias and common-cause from redundancy in the British fossil record
(Peer reviewed; Journal article, 2014-09-04)The fossil record documents the history of life, but the reliability of that record has often been questioned. Spatiotemporal variability in sedimentary rock volume, sampling and research effort especially frustrates ... -
Disentangling source of moisture driving glacier dynamics and identification of 8.2 ka event: evidence from pore water isotopes, Western Himalaya
(Journal article; Peer reviewed, 2020)Two atmospheric circulation patterns, the Indian Summer Monsoon (ISM) and mid-latitude Westerlies control precipitation and thus glacier variability in the Himalaya. However, the role of the ISM and westerlies in controlling ... -
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 ... -
Disentangling the impact of air-sea interaction and boundary layer cloud formation on stable water isotope signals in the warm sector of a Southern Ocean cyclone
(Journal article; Peer reviewed, 2022)Stable water isotopes in marine boundary layer water vapour are strongly influenced by the strength of air–sea fluxes. Air–sea fluxes in the extratropics are modulated by the large-scale atmospheric flow, for instance by ... -
Disentangling the impact of Atlantic Niño on sea-air CO2 flux
(Journal article; Peer reviewed, 2023)Atlantic Niño is a major tropical interannual climate variability mode of the sea surface temperature (SST) that occurs during boreal summer and shares many similarities with the tropical Pacific El Niño. Although the ... -
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 ... -
Disko Bay sea-ice variability: Oceanic and Atmospheric drivers
(Master thesis, 2023-11-20)Climate change impacts the Arctic sea-ice cover and thickness with a related Arctic Amplification and an increased ocean heat transport towards the Arctic. There has been a profound decline of Arctic winter sea-ice extent, ... -
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 ...
