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 ... -

Impact of TiO2 nanoparticles on freshwater bacteria from three Swedish lakes
(Journal article; Peer reviewed, 2015)Due to the rapidly rising production and usage of nano-enabled products, aquatic environments are increasingly exposed to engineered nanoparticles (ENPs), causing concerns about their potential negative effects. In this ... -
Impact of whitefish on Cladocera communities
(Master thesis, 2019)Introduserte arter har blitt vist å ha effekter på lokal populasjoner både i eksperimenter og i studier av økosystemer. For å kunne ivareta biodiversitet og økosystemtjenester er økt forståelse av menneskelig påvirkning ... -
Impacts of a warming climate on concentrations of organochlorines in a fasting high arctic marine bird: Direct vs. indirect effects?
(Peer reviewed; Journal article, 2024)The present study examined how climate changes may impact the concentrations of lipophilic organochlorines (OCs) in the blood of fasting High Arctic common eiders (Somateria mollissima) during incubation. Polychlorinated ... -
Impacts of an invasive plant on primary production: Testing a functional trait-based framework with a greenhouse experiment
(Journal article; Peer reviewed, 2018)Questions Predicting when invasive species will affect ecosystem functioning remains problematic, with strong contingency upon both the invasive species and the recipient community's identities. Adopting a functional ... -
Impacts of artificial light at night in marine ecosystems—A review
(Peer reviewed; Journal article, 2022)The globally widespread adoption of Artificial Light at Night (ALAN) began in the mid-20th century. Yet, it is only in the last decade that a renewed research focus has emerged into its impacts on ecological and biological ... -
Impacts of food contact chemicals on human health: A consensus statement
