Impact of dietary carbohydrate/protein ratio on hepatic metabolism in land-locked Atlantic salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2018)A common-garden experiment was carried out to compare two genetically distinct strains of Atlantic salmon (Salmo salar) fed diets with either high (CHO) or low (NoCHO) digestible carbohydrate (starch). Twenty salmon from ... -
Impact of early life stress on behaviour and dorsal raphe serotonergic activity in zebrafish (Danio rerio)
(Doctoral theses at NTNU;2021:317, Doctoral thesis, 2021)Exposure to stress in early life stages may lead to structural and functional changes in a developing brain. These changes can increase the risk of cognitive and behavioural abnormalities, which further increase the risk ... -
The impact of exposure timing on embryo mortality and the partitioning of PAHs when cod eggs are exposed to dispersed and dissolved crude oil
(Peer reviewed; Journal article, 2022)During sub-sea oil spills to the marine environment, oil droplets will rise towards the sea surface at a rate determined by their density and diameter as well as the vertical turbulence in the water. Micro-droplets (< 50 ... -
IMPACT OF FIRE HISTORY ON CARBON STORAGE AND VEGETATION STRUCTURE IN THE SAVANNA ECOSYSTEM OF MOLE NATIONAL PARK IN THE NORTHERN REGION OF GHANA
(Master thesis, 2017)As a management tool to balance the existence of trees and herbaceous vegetation, many protected areas in savannas are undergoing a trend of burning. Management to reduce late dry season fires and focus on low intensity ... -
Impact of genetics and epigenetic processes on parasite infection dynamics in the house sparrow
(Doctoral theses at NTNU;2022:399, Doctoral thesis, 2022)Parasites are important drivers of ecological and evolutionary processes in natural populations, and can exert strong selective pressures on their hosts by reducing host fitness. Investigating the mechanisms involved in ... -
