Moult location and diet of auks in the North Sea inferred from coupled light-based and isotope-based geolocation
(Journal article; Peer reviewed, 2018)Many pelagic seabirds moult their feathers while at sea, which is an energetically costly behaviour. Mortality rates during moult can be high, so spatial and trophic ecology during this critical period is important for ... -
Movement and growth of European grayling Thymallus thymallus in two Norwegian rivers
(Master thesis, 2012)Dersom forflytningsmønster er et trekk som er stabilt gjennom livet, er det flere årsaker til å anta at det kan påvirke vekst i de tidligere livsstadiene hos harr (Thymallus thymallus). Siden vekst før kjønnsmodning hos ... -
Movement syndromes of a Neotropical frugivorous bat inhabiting heterogeneous landscapes in Brazil
(Peer reviewed; Journal article, 2021)Background There is growing evidence that individuals within populations can vary in both habitat use and movement behavior, but it is still not clear how these two relate to each other. The aim of this study was to ... -
Moving out of town? The status of alien plants in high‐Arctic Svalbard, and a method for monitoring of alien flora in high‐risk, polar environments
(Peer reviewed; Journal article, 2021)1. Rising human activity in the Arctic, combined with a warming climate, mincreases the probability of introduction and establishment of alien plant species. While settlements are known hotspots for persistent populations, ... -
Multi-generation genetic and fitness effects of immigration in a natural meta-population of song sparrows (Melospiza melodia)
(Doctoral theses at NTNU;2024:105, Doctoral thesis, 2024)Fragmentation leads to smaller habitat patches and population sizes, endangering population fitness and persistence, including through inbreeding depression and loss of genetic diversity. These effects can be mitigated ... -
Multi-Layer, Multi-Segment Iterative Optimization for Maritime Supply Chain Operations in a Dynamic Fuzzy Environment
(Peer reviewed; Journal article, 2020)This study aims to develop a multi-layer, multi-segment iterative optimization algorithm for the operations of a single agent, which can be either a container in a distribution system, an automated guided vessel in a ... -
Multicolony tracking reveals potential threats to little auks wintering in the North Atlantic from marine pollution and shrinking sea ice cover
(Journal article; Peer reviewed, 2013)Aim Extensive development of human activities in combination with ocean warming is rapidly modifying marine habitats in the Arctic and North Atlantic regions. To understand the potential impacts on marine biodiversity, ... -
Multicolor flowcytometrisk immunfenotyping for B-cellepopulasjoner i blod- og benmargsprøver
(Master thesis, 2011)Denne oppgaven har hatt som mål å finne egnete multicolor antistoffkombinasjoner for identifisering av B-cellepopulasjoner i blod og benmarg ved hjelp av flowcytometrisk immunfenotyping. B-cellepopulasjoner av interesse ... -
Multidimensional approaches for studying plant defence against insects: from ecology to omics and synthetic biology
(Journal article; Peer reviewed, 2015)The biggest challenge for modern biology is to integrate multidisciplinary approaches towards understanding the organizational and functional complexity of biological systems at different hierarchies, starting from the ... -
Multigenerational exposure to ocean acidification during food limitation reveals consequences for copepod scope for growth and vital rates
(Journal article; Peer reviewed, 2014)The copepod Calanus finmarchicus is a key component of northern Atlantic food webs, linking energy-transfer from phytoplankton to higher trophic levels. We examined the effect of different ocean acidification (OA) scenarios ... -
Multiple aspects of plasticity in clutch size vary among populations of a globally distributed songbird
(Journal article, 2014)Plasticity in life-history characteristics can influence many ecological and evolutionary phenomena, including how invading organisms cope with novel conditions in new locations or how environmental change affects organisms ... -
Multiple Environmental Stressors: Biological Interactions Between Parameters of Climate Change and Perfluorinated Alkyl Substances in Fish
(Doctoral thesis at NTNU;2016:100, Doctoral thesis, 2016)Aquatic organisms continuously acclimatize to fluctuations in environment parameters and contaminant insult. The aim of this thesis was to investigate effects of combined exposure to quantifiable measures of climate ... -
Multiple-stressor effects in an apex predator: combined influence of pollutants and sea ice decline on lipid metabolism in polar bears
(Journal article; Peer reviewed, 2017)There is growing evidence from experimental and human epidemiological studies that many pollutants can disrupt lipid metabolism. In Arctic wildlife, the occurrence of such compounds could have serious consequences for ... -
Multipurpose peptides: The venoms of Amazonian stinging ants contain anthelmintic ponericins with diverse predatory and defensive activities
(Peer reviewed; Journal article, 2021)In the face of increasing drug resistance, the development of new anthelmintics is critical for controlling nematodes that parasitise livestock. Although hymenopteran venom toxins have attracted attention for applications ... -
Multitarget nociceptor sensitization by a promiscuous peptide from the venom of the King Baboon spider

Muscle growth and development in lumpfish (Cyclopterus lumpus) larvae in relation to start-feeding diets (Artemia, cirripedia, copepod (Acartia tonsa) and formulated diet)
(Master thesis, 2021)Oppdrett av Atlantisk laks (Salmo salar) i Norge har vært negativt påvirket av lakselus (Lepeophtheirus salmonis) i en lengre periode. Ulike kjemiske midler har blitt brukt for å bli kvitt lakselusen, men en høyere resistans ... -
Muscular and metabolic load and manual function when working in the cold
(Doctoral theses at NTNU;2021:95, Doctoral thesis, 2021)Work in cold environments bring challenges to maintain health and performance. Two important differences when working in cold compared to neutral or warm conditions are: personal protective clothing (PPC) worn and reduced ... -
Mutagenic Potential of Spruce-derived fast Pyrolysis Oil measured by the Ames Salmonella assay
(Master thesis, 2014)Biomass conversion to biofuels is promising for production of renewable energy. Biofuels are sustainable, CO2-neutral, recognized to be cleaner than fossil fuels, but their combustion generates noxious gases and genotoxic ... -
Mutagenicity and induction of CYP1A- enzymes from organic extracts of soil samples from nursery schools, evaluated by in vitro studies
(Master thesis, 2011)Polluted soil can be a problem in urban areas, and can have a direct impact on human health upon exposure. The toxic potential of mixtures can be mediated by constituents and information about toxicity of mixtures is ... -
