A Dual Binary System for Investigating Microenvionmental Influence on Metastasis in vivo
(Master thesis, 2024-06-03) -
Abrupt change in tropical Pacific climate mean state during the Little Ice Age
(Journal article; Peer reviewed, 2023)The mean state of the tropical Pacific ocean-atmosphere climate, in particular its east-west asymmetry, has profound consequences for regional climates and for the El Niño/Southern Oscillation variability. Here we present ... -
Acacia trees on the cultural landscapes of the Red Sea Hills
(Peer reviewed; Journal article, 2014-07-18)This paper examines interactions between five pastoral nomadic culture groups of the Egyptian and Sudanese Red Sea Hills and the acacia trees Acacia tortilis (Forssk.) Hayne subsp. tortilis and subsp. raddiana growing in ... -
Accumulation and distribution of microplastics in coastal sediments from the inner Oslofjord, Norway
(Journal article; Peer reviewed, 2021)Microplastic presence in benthic marine systems is a widely discussed topic. The influence of the natural matrix on microplastic distribution within the sedimentary matrix is often overlooked. Marine sediments from the ... -
Acoustic attenuation by air bubble in bad weather conditions; a comparison of hull- and keel-mounted transducers
(Master thesis, 2009-08-25)Echo integration in bad weather conditions is problematic due to vessel- and wind-induced air bubble layer that is formed below the hull of a vessel, where acoustic transducers are mounted. The bubbles below the hull ... -
Acoustic Delicing of Atlantic Salmon (Salmo salar): Fish Welfare and Salmon Lice (Lepeophtheirus salmonis) Dynamics
(Journal article; Peer reviewed, 2022)Acoustic lice treatment (AcuLice) is a newly developed system, which uses a composite acoustic sound image with low-frequency sound to remove salmon lice (Lepeophtheirus salmonis) from Atlantic salmon (Salmo salar). This ... -
Acoustic telemetry predation sensors reveal the tribulations of Atlantic salmon (Salmo salar) smolts migrating through lakes
(Journal article; Peer reviewed, 2021)Smolt migration through lakes is hazardous, as the predation pressure can be extreme and the hydrology a great contrast to that of a riverine area. However, the mechanisms yielding these challenges have been scarcely ... -
Actin N-terminal acetylation impacts cell adhesion and invasion
(Master thesis, 2019-12-14) -
Actions on sustainable food production and consumption for the post-2020 global biodiversity framework
(Journal article; Peer reviewed, 2021)Current food production and consumption trends are inconsistent with the Convention on Biological Diversity’s 2050 vision of living in harmony with nature. Here, we examine how, and under what conditions, the post-2020 ... -
Activation mechanism and activity of globupain, a thermostable C11 protease from the Arctic Mid-Ocean Ridge hydrothermal system
(Journal article; Peer reviewed, 2023)Deep-sea hydrothermal vents offer unique habitats for heat tolerant enzymes with potential new enzymatic properties. Here, we present the novel C11 protease globupain, which was prospected from a metagenome-assembled genome ... -
Acute effects of gas supersaturation on Atlantic salmon smolt in two Norwegian rivers
(Journal article; Peer reviewed, 2020)Total dissolved gas (TDG) supersaturation downstream of hydropower plants may cause gas bubble disease (GBD) and harmful effects in fish. Little is known about tolerance levels of TDG supersaturation on Atlantic salmon ... -
Adaptation of anemonefish to their host anemones: From Genetics to Physiology
(Doctoral thesis, 2020-02-21)The mutualism between anemonefish and anemones can be studied in terms of permanent or temporary adaptation of fish toward their host anemones. This thesis explores this theme, and aims to test (1) Whether a mutual ... -
Adaptation of unbiased stereological methods to study theeffects of feed composition on the morphometrics of the different layers of the digestive tract of juvenile Atlantic cod (Gadus morhua L.)
(Master thesis, 2004)Juveniles of Atlantic cod (Gadus morhua L.) were fed food, containing different compositions of macro-nutrients (proteins, fat and carbohydrates). The aims of this study were to evaluate the use of unbiased stereology to ... -
Adaptive and plastic variation in growth and maturation of the cutlassfish Trichiurus japonicus in the subtropical Pacific Ocean
(Peer reviewed; Journal article, 2018) -
Adaptive evolution of viruses infecting marine microalgae (haptophytes), from acute infections to stable coexistence
(Journal article; Peer reviewed, 2022)Collectively known as phytoplankton, photosynthetic microbes form the base of the marine food web, and account for up to half of the primary production on Earth. Haptophytes are key components of this phytoplankton community, ... -
Adaptive host responses to infection can resemble parasitic manipulation
(Journal article; Peer reviewed, 2023)Using a dynamic optimisation model for juvenile fish in stochastic food environments, we investigate optimal hormonal regulation, energy allocation and foraging behaviour of a growing host infected by a parasite that only ... -
Adaptive Humoral Immune Response in Lumpfish, Cyclopterus lumpus L.
(Master thesis, 2015-10-05)The lumpfish, Cyclopterus lumpus L. is an emerging and most promising aquaculture fish currently used for a biological control against sea lice in salmonids. However, the lumpfish is prone to a number of bacterial diseases ... -
Adaptive immune responses in Atlantic salmon after vaccination with bacterins of Pasteurella atlantica
(Master thesis, 2022-06-01)Utbrot av pasteurellose hjå atlanterhavslaks (Salmo salar L.) har sidan 2018 vore eit stort problem i oppdrettsnæringa, og framleis har inga kommersielt tilgjengeleg vaksine blitt utvikla. Vi veit lite om bakteriens ... -
Adding pieces to the puzzle: insights into diversity and distribution patterns of Cumacea (Crustacea: Peracarida) from the deep North Atlantic to the Arctic Ocean
(Journal article; Peer reviewed, 2021)The Nordic Seas have one of the highest water-mass diversities in the world, yet large knowledge gaps exist in biodiversity structure and biogeographical distribution patterns of the deep macrobenthic fauna. This study ...
