Density-independent mortality at early life stages increases the probability of overlooking an underlying stock-recruitment relationship
(Journal article; Peer reviewed, 2021)Abstract Beverton and Holt’s (1957) monograph contributed a widely used stock–recruitment relationship (BH-SRR) to fisheries science. However, because of variation around a presumed relationship between spawning biomass ... -
Depletion of the human N-terminal acetyltransferase hNaa30 disrupts Golgi integrity and ARFRP1 localization
(Peer reviewed; Journal article, 2017-04-28)The organization of the Golgi apparatus (GA) is tightly regulated. Golgi stack scattering is observed in cellular processes such as apoptosis and mitosis, and has also been associated with disruption of cellular lipid ... -
Desmozoon lepeophtherii as a pathogen in Norwegian salmon aquaculture
(Master thesis, 2011-06-01)During late summer and autumn 2008 the Norwegian Veterinary Institute Bergen received several diagnostic cases with similar histopathological changes. Due to unknown cause of the the condition it was subsequently called ... -
Detection of misfolded protein aggregates from a clinical perspective
(Peer reviewed; Journal article, 2016)Neurodegenerative Protein Misfolding Diseases (PMDs), such as Alzheimer’s (AD), Parkinson’s (PD) and prion diseases, are generally difficult to diagnose before irreversible damage to the central nervous system damage has ... -
Detection of the myxosporean parasite Parvicapsula pseudobranchicola in Atlantic salmon (Salmo salar L.) using in situ hybridization (ISH)
(Peer reviewed; Journal article, 2015-02-15)Background: Parvicapsula pseudobranchicola is a marine myxosporean parasite infecting farmed Atlantic salmon (Salmo salar). A major site for the parasite is the pseudobranch, which may be destroyed in heavily infected fish. ... -
Developing common protocols to measure tundra herbivory across spatial scales
(Journal article; Peer reviewed, 2021)Understanding and predicting large-scale ecological responses to global environmental change requires comparative studies across geographic scales with coordinated efforts and standardized methodologies. We designed, ... -
Developing Molecular Tools to study Trophic Interactions in zooplankton and their implementation in a vent system -Norwegian Sea Hydrothermal Vents
(Doctoral thesis, 2014-06-27)Understanding hydrothermal plumes in the Arctic and Nordic Seas is an important objective for ecosystem assessments of these habitats. Very little is known about what role the hydrothermal plumes play in the Nordic Seas. ... -
Developing positional awareness in sustainability science: four archetypes for early career scientists working in an SDG world
(Journal article; Peer reviewed, 2022)Although the Sustainable Development Goals (SDGs) provide a framework to guide and inform research at the interface between science and policy, engaging in sustainability science is not a value-free process and implies ... -
Development of 14 Microsatellite Markers for Zoonotic Tapeworm Dibothriocephalus dendriticus (Cestoda: Diphyllobothriidea)
(Journal article; Peer reviewed, 2020)Dibothriocephalus dendriticus is one of the causative agents of the fish-borne zoonosis diphyllobothriosis. Polymorphic microsatellite markers were originally developed for future genetic studies using microsatellite library ... -
Development of a new real-time PCR for the detection of pilchard orthomyxovirus (POMV) in apparently healthy fish
(Journal article; Peer reviewed, 2022)Pilchard orthomyxovirus (POMV) is a virus of concern to the Atlantic salmon aquaculture industry in Tasmania. First isolated from wild pilchards in southern Australia in 1998, the virus is now a recognised pathogen of ... -
Development of a vaccine against salmon louse (Lepeophtheirus salmonis)
(Master thesis, 2018-06-26)Aquaculture is a growing industry whilst facing a major problem, the ectoparasite Lepeophtheirus salmonis. Parasite control in 2015 was estimated to cost 5 billion NOK. The challenges with the parasite are complex, and the ... -
Development of anaesthetic protocols for lumpfish (Cyclopterus lumpus L.): Effect of anaesthetic concentrations, sea water temperature and body weight
(Peer reviewed; Journal article, 2017-07-05)In recent years, use of lumpfish (Cyclopterus lumpus L.) as cleaner-fish to remove sea-lice have been chosen by many salmon farmers in Europe and Canada as an alternative to medical treatment, which has led to large scale ... -
Development of chemogenetic tools from invertebrate ion channels
(Doctoral thesis, 2023-09-28)Reseptorer som er konstruert for heterolog ekspressjon og aktivitet kun som respons på spesifikke eksogene ligander er kjent som kjemogenetiske verktøy og brukes til å studere hjernefunksjon ved å nøyaktig modulere elektrisk ... -
The development of early pioneer neurons in the annelid Malacoceros fuliginosus
(Journal article; Peer reviewed, 2020)Background Nervous system development is an interplay of many processes: the formation of individual neurons, which depends on whole-body and local patterning processes, and the coordinated growth of neurites and synapse ... -
Development of flow cytometry-based techniques for assessing microbial inactivation after water disinfection and downstream processes
(Doctoral thesis, 2023-01-17)Overvåking av mikrobiell vitalitet i akvatiske miljøer kan være utfordrende. Flere metoder er tilgjengelig, og Flow cytometri (FCM) analyser er en effektiv måte å få informasjon om mikrobene. Å kombinere ulike liv/død-farginger ... -
Development of infectious cDNA clones of Salmonid alphavirus subtype 3
(Peer reviewed; Journal article, 2010-09-21)Background: Salmonid alphavirus (SAV) is a widespread pathogen in European aquaculture of salmonid fish. Distinct viral subtypes have been suggested based on sequence comparisons and some of these have different geographical ... -
Development of novel methods to evaluate availability of zinc, selenium and manganese in Atlantic salmon (Salmo salar)
(Doctoral thesis, 2019-06-06)During the recent years, the composition of salmonids diets has changed from the use of mainly marine-based ingredients (e.g. fish meal and fish oil) to an increased use of plant-based ingredients (e.g. soybean meal and ... -
