(VKM Report;, Research report, 2013)The Norwegian Scientific Committee for Food Safety (Vitenskapskomiteen for mattrygghet, VKM) has on request of the Norwegian Food Safety Authority performed a risk assessment of aluminium exposure though food and the use ... -
Risk assessment of “other substances” – Inulin. Opinion of the Panel on Food Additives, Flavourings, Processing Aids, Materials in Contact with Food and Cosmetics of the Norwegian Scientific Committee for Food Safety
(VKM Report;, Research report, 2016)The Norwegian Scientific Committee for Food Safety (VKM) has, at the request of the Norwegian Food Safety Authority, assessed the risk of intake of 3 g/day of inulin in food supplements. In the risk characterization, the ... -
A risk assessment review of mercury exposure in Arctic marine and terrestrial mammals
(Peer reviewed; Journal article, 2022)There has been a considerable number of reports on Hg concentrations in Arctic mammals since the last Arctic Monitoring and Assessment Programme (AMAP) effort to review biological effects of the exposure to mercury (Hg) ... -
Risk assessments of aspartame, acesulfame K, sucralose and benzoic acid from soft drinks, “saft”, nectar and flavoured water. Opinion of the Panel on Food Additives, Flavourings, Processing Aids, Materials in Contact with Food and Cosmetics of the Norwegian Scientific Committee for Food Safety
(VKM Report;, Research report, 2014)The Norwegian Scientific Committee for Food Safety (Vitenskapskomiteen for mattrygghet, VKM), Panel on Food Additives, Flavourings, Processing Aids, Materials in Contact with Food and Cosmetics, has at the request of the ... -
Risk of Feed Additives in High-lipid Fish Diets: Effects of Propionate and Docosahexaenoic Acid on Liver and Intestinal Health in Zebrafish (Danio rerio Hamilton-Buchanan, 1822)
(Doctoral theses at NTNU;2022:378, Doctoral thesis, 2022)The use of high-fat diets (HFDs) is a common practice employed to improve growth and feed efficiency in aquaculture. Propionic acid and its sodium salt are widely used in Asian fish feeds as a safe inhibitor of mold growth, ... -
Risk-based management framework for microplastics in aquatic ecosystems
(Peer reviewed; Journal article, 2022)Microplastic particles (MPs) are ubiquitous across a wide range of aquatic habitats but determining an appropriate level of risk management is hindered by a poor understanding of environmental risk. Here, we introduce a ... -
River migration of sea trout Salmo trutta in River Beiarelva, Northern Norway
(Master thesis, 2021)Sjøørret (Salmo trutta) vandrer tilbake til elva for gyting og ofte også for overvintring, og forholdene under denne kritiske delen av sjøørretens livsløp er avgjørende for bestandens levedyktighet. Denne oppgaven undersøkte ... -
Road Constraints on Impala (Aepyceros melampus) Behavior
(Master thesis, 2014)Protected areas play a key role in safeguarding and sustaining biological diversity. The development of infrastructure in protected areas facilitates management and tourism operations. However, infrastructure can affect ... -
Robustness of linear mixed-effects models to violations of distributional assumptions
(Peer reviewed; Journal article, 2020)Linear mixed-effects models are powerful tools for analysing complex datasets with repeated or clustered observations, a common data structure in ecology and evolution. Mixed-effects models involve complex fitting procedures ... -
Rodent population dynamics affect seedling recruitment in alpine habitats
(Journal article; Peer reviewed, 2014)Questions How do rodents with cyclic population dynamics affect seedling recruitment in alpine habitats? Does disturbance from rodents have larger implications on seedling recruitment in some plant communities than in ... -
Roe deer face competing risks between predators along a gradient in abundance
(Journal article; Peer reviewed, 2013)Mortality rates and patterns are fundamental demographic traits for understanding the dynamics of populations of large herbivores in different environments. Despite the ongoing recovery of large carnivores in Europe and ... -
The Role of a Glucosinolate-Derived Nitrile in Plant Immune Responses
(Peer reviewed; Journal article, 2020)Glucosinolates are defense-related secondary metabolites found in Brassicaceae. When Brassicaceae come under attack, glucosinolates are hydrolyzed into different forms of glucosinolate hydrolysis products (GHPs). Among the ... -
The role of life history and movement in spatial population synchrony: Theoretical and empirical investigations
(Doctoral theses at NTNU;2023:367, Doctoral thesis, 2023)Spatial population synchrony, the correlated fluctuation of population abundances in different places, is common between populations of the same species and an important predictor of extinction risk. Spatially separated ... -
The role of manipulating photoperiod and temperature in oocyte development of the polychaete hediste diversicolor (O.F. Müller, 1976)
(Peer reviewed; Journal article, 2020)Three different experiments were conducted to examine the oocyte development of the polychaete Hediste diversicolor in response to changing photoperiod and temperature at three different periods of oogenesis. In experiment ... -
The role of mechanoperception in plant cell wall integrity maintenance
(Peer reviewed; Journal article, 2020)The plant cell walls surrounding all plant cells are highly dynamic structures, which change their composition and organization in response to chemical and physical stimuli originating both in the environment and in plants ... -
