Effects of elevated water temperatures and microalgae diet on prosome size, fat sac development, egg production and hatching success in Calanus finmarchicus.
(Master thesis, 2021)Raudåta (Calanus finmarchicus, Gunnerus) er en nøkkelart i Barents- og Norskehavet på grunn av sin tallrikhet og betydning knyttet til energioverføring mellom primærprodusenter og kommersielle fiskearter. Slik som mange ... -
Effects of energetic state and social environment on individual foraging strategies in a population of house sparrows, Passer domesticus
(Master thesis, 2023)Hvordan variasjon i adferd blant individer som er del av samme populasjon or er utsatt for de samme seleksjonstrykkene blir vedlikeholdt, er ennå uvisst blant evolusjonsbiologer, siden de forventes å ha utviklet de samme ... -
Effects of environmental exposure: Interplay between helix-distorting and oxidative DNA lesions and their repair
(Master thesis, 2012)DNA lesions are introduced in all living organisms every day, both via endogenous processes and by exposure to an array of DNA damaging agents. DNA lesions require repair for the sustenance of life. Base excision repair ... -
Effects of environmental factors on growth and development of Phaeodactylum tricornutum
(Master thesis, 2023)Diatoms are eukaryotic photosynthetic organisms found in marine and freshwater environments as primary producers accounting for ~20% of total world photosynthetic output and ~50% of oceanic biomass. Diatoms are of industrial ... -
Effects of Experimental Icing and Summer Warming on the Polar Willow Salix polaris on Svalbard
(Master thesis, 2017)The effects of climate change are particularly strong in the Arctic, where temperatures are increasing rapidly. While a clear trend of a more productive and greener Arctic in response to summer warming has been confirmed ... -
Effects of Experimental Winter Icing and Summer Warming on High Arctic Plant Phenology
(Master thesis, 2017)Climate change is expected to have pronounced effects in the Arctic, causing increased temperatures and changes in winter precipitation patterns. For instance, extreme winter rain events often result in ground ice formations ... -
Effects of experimental winter icing and summer warming on high Arctic tundra vascular plants: a comparison of growth forms
(Master thesis, 2017)No other place has experienced such pronounced changes in temperature and precipitation due to climate change, as the terrestrial Arctic. Ecological responses to warmer summers are already well documented, yet the responses ... -
Effects of Experimental Winter Warming on Trade-offs Between Growth and Reproduction in High Arctic shrubs
(Master thesis, 2022)Arktis varmes fortere enn det globale gjennomsnittet, og frekvensen av ekstremvær om vinteren øker. Bakkeis og tine-fryse episoder er to mulige utfall av ekstreme varmeperioder på vinteren og vinterregn. Disse kan dekke ... -
Effects of Exposure Timing on cyp1a Expression, PAH Elimination, and Lipid Utilization in Lumpfish Embryos Exposed to Produced Water
(Peer reviewed; Journal article, 2023)Intentional discharges of produced water from oil production platforms to the marine environment contain a complex mixture of toxicants, including polycyclic aromatic hydrocarbons (PAHs). Early life stages of fish are ... -
Effects of feeding with copepod nauplii (Acartia tonsa) compared to rotifers (Brachionus ibericus, Cayman) on quality parameters in Atlantic cod (Gadus morhua) larvae
(Master thesis, 2011)Good nutritional quality is a key for a successful Atlantic cod (Gadus morhua) juvenile producer. Copepods are the natural prey for marine fish larvae, and its nutritional composition is believed to be optimal for the ... -
Effects of fire on large herbivores and their forage resources in Serengeti, Tanzania
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:239, Doctoral thesis, 2007)Fire is one of the major ecological factors that determines structure and function of grassland and savanna ecosystems through its effects on soil nutrient pools, floristic composition and primary production, and foraging ... -
The effects of fish meal replacement with ultra-micro ground mixed plant proteins (uPP) in practical diet on growth, gut and liver health of common carp (Cyprinus carpio)
(Peer reviewed; Journal article, 2020)Plant proteins are widely used for fish meal replacement in aquafeeds, but anti-nutritional factors in plant protein reduce fish growth performance and impair fish health. The present work aimed to study the effects of ... -
Effects of gadolinium (Gd) and a Gd-based contrast agent (GBCA) on early life stages of zebrafish (Danio rerio)
(Peer reviewed; Journal article, 2023)Gadolinium (Gd) is one of the rare earth elements (REY) and is widely used in magnetic resonance imaging (MRI) contrast agents. Anthropogenic Gd enrichment has frequently been found in wastewater treatment plant effluents ... -
Effects of inbreeding on fitness-related traits in a small isolated moose population
(Journal article; Peer reviewed, 2013)Inbreeding can affect fitness-related traits at different life history stages and may interact with environmental variation to induce even larger effects. We used genetic parentage assignment based on 22 microsatellite ... -
Effects of inbreeding on lay date in house sparrows (Passer domesticus)
(Master thesis, 2021)Innavlsdepresjon (en reduksjon i individuell fitness forårsaket av innavl) har blitt observert hos mange ulike arter, men mekanismene som gir innavlsdepresjon er fremdeles uklare. Innavl og innavlsdepresjon studeres vanligvis ... -
“Effects of inbreeding on nestling fitness in an insular house sparrow metapopulation in northern Norway”
(Master thesis, 2022)Inbreeding may contribute to the extinction risk of small and fragmented populations by reducing individual fitness (inbreeding depression). Quantifying inbreeding depression (ID) in early life-stages is vital for understanding ... -
Effects of individual variation on social foraging dynamics in the house sparrow, Passer domesticus
(Master thesis, 2023)Personlighet hos dyr blir definert som konsekvente individuelle forskjeller i gjennomsnittlig atferd. I et sosialt miljø kan slike forskjeller bli formet av individuelle iboende egenskaper, samt indirekte fitness-effekter ... -
Effects of intra- and interspecific competition and hydropeaking on growth of juvenile Atlantic salmon (Salmo salar)
