Temporal variation in faecal testosterone metabolite concentrations and mate-guarding behaviour in the Arctic fox (Vulpes lagopus)
(Master thesis, 2024)Atferd og de underliggende fysiologiske mekanismene som påvirker atferd er regulert gjennom sesongene for å maksimere fitness — sikre overlevelse og øke reproduktiv suksess. Å forstå de mekanismene som regulerer paring og ... -
Spring phenology and selection for earlier egg laying in house sparrows in northern Norway
(Master thesis, 2024)The breeding phenology of species is intricately linked to the effect of environmental conditions. Environmental changes can lead to mismatches between the timing of reproduction and optimal conditions, posing challenges ... -
The effect of small-scale partially protected areas on European lobster (Homarus gammarus) abundance and demographics – a citizen science-based study
(Master thesis, 2024)Overfiske er en av de største driverne for tap av biologisk mangfold i havet. Marine verneområder har fått økende oppmerksomhet som mulige forvaltningsverktøy for å gjenoppbygge marine populasjoner og økosystemer. Dette ... -
Population dynamics of coexisting species: lessons on interspecific population synchrony and the role of environmental fluctuations
(Doctoral theses at NTNU;2024:356, Doctoral thesis, 2024)English summary In natural communities, coexisting species are exposed to similar environmental conditions. If species respond similarly to these conditions, this can cause their population abundances to co-fluctuate ... -
Effects of freshwater delousing on hatching success, larval development and tolerance to low salinities in salmon lice (Lepeophtheirus salmonis)
(Master thesis, 2024)«Det norske lakseeventyret» er på mange måter en suksesshistorie, men den enorme veksten i oppdrettsnæringen siden 1970-tallet har også ført til en økning av lakselus (Lepeophtheirus salmonis) langs kysten. Den robuste ... -
Investigating the integration of multiple visual cues in the Monarch butterfly (Danaus plexippus) brain
(Master thesis, 2024)Monarksommerfugler (Danaus plexippus) er kjent for deres navigasjonsevner. Hver høst migrerer en ny generasjon sommerfugler tusenvis av kilometer fra nordlige USA til Mexico. Å avdekke gåten om hvordan disse sommerfuglene ... -
Evaluating seasonal biological responses in Saccharina latissima and kelp-driven changes in seawater DIC and pH across two sites
(Master thesis, 2024)Vannkvalitet og fysiske miljøparametere regulerer biokjemiske prosesser i makroalger. For å sikre vellykket makroalgekultivering og maksimere økosystemfordelene industrien kan gi, er det avgjørende å forstå hvordan ytre ... -
Long-distance dispersal in the short-distance dispersing house sparrow (Passer domesticus)
(Journal article; Peer reviewed, 2024)The house sparrow (Passer domesticus) is a small passerine known to be highly sedentary. Throughout a 30-year capture–mark–recapture study, we have obtained occasional reports of recoveries far outside our main metapopulation ... -
epegRNA Screening Platform for Primary Immunodeficiency Mutations in HEK293 cells and Hematopoietic Stem and Progenitory Cells (HSPCs)
(Master thesis, 2024)Mangel på adenosindeaminase (DADA2) er en primær immunsvikt forårsaket av autosomale recessive mutasjoner i adenosindeaminasegen (CECR1, ADA2). Korrekte behandlingsmetoder er først og fremst avhengig av sykdomsfenotypen, ... -
Dynamic Boolean modeling of molecular and cellular interactions in psoriasis predicts drug target candidates
(Journal article; Peer reviewed, 2024)Psoriasis arises from complex interactions between keratinocytes and immune cells, leading to uncontrolled inflammation, immune hyperactivation, and a perturbed keratinocyte life cycle. Despite the availability of drugs ... -
Endocrine and metabolism disrupting chemicals in plastic food packaging: Addressing the unknowns
(Doctoral theses at NTNU;2024:359, Doctoral thesis, 2024)Over 16,000 chemicals are used in or present in plastics, with more than a quarter known to be hazardous and over 10,000 lacking basic data on identity, functionality, and toxicity. In addition, plastics contain numerous ... -
Two decades of increasing functional and phylogenetic richness in a mountaintop flora in central Norway
(Journal article; Peer reviewed, 2024)Questions: Analysing how multiple facets of biodiversity vary across space and time can help to predict the vulnerability of mountaintop floras to future environmental changes. Here we addressed the following questions: ... -
Phaeodactylum tricornutum tolerance to cadmium and copper
(Master thesis, 2024)Industrialiseringen har ført til økt utslipp av tungmetaller i både akvatiske og terrestriske miljøer, og dette kan ha stor påvirkning på levende organismer, inkludert marine mikroalger. Til tross for mikrogalgers fundamentale ... -
Storylines of summer Arctic climate change constrained by Barents-Kara seas and Arctic tropospheric warming for climate risk assessment
(Peer reviewed; Journal article, 2024)While climate models broadly agree on the changes expected to occur over the Arctic with global warming on a pan-Arctic scale (i.e. polar amplification, sea ice loss, and increased precipitation), the magnitude and patterns ... -
Behavioural Response of Nauplii and Copepodid stages of Salmon Lice (Lepeophtheirus salmonis) to different Light Stimuli
(Master thesis, 2024)Lepeophtheirus salmonis (Krøyer, 1837), kjent som lakselus, er en ektoparasittisk hoppekreps som infesterer ulike laksefiskarter, inkludert oppdrettslaks (Salmo salar). L. salmonis lever av slim, blod, epidermis og ... -
