Skeletonema marinoi ecotypes show specific habitat-related responses to fluctuating light supporting high potential for growth under photobioreactor light regime
(Journal article; Peer reviewed, 2024)* Diatoms are a diverse group of phytoplankton usually dominating areas characterized by rapidly shifting light conditions. Because of their high growth rates and interesting biochemical profile, their biomass is considered ... -
Effects of dietary phospholipids and bile salt on larval performance, ossification, and skeletal anomalies in Atlantic cod (Gadus morhua)
(Master thesis, 2024)Nivået av fosfolipider i kosten kan påvirke vekst, beinmineralisering og skjelettanomalier hos fiskelarver, og tilskudd av gallesalter kan bidra til fordøyelse og opptak av fett i larve- og juvenilstadiet. Denne studien ... -
Comparing physiological responses of acute and chronically stressed diploid and triploid Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2024)We compared the performance and physiological response of diploid and triploid Atlantic salmon (Salmo salar) following 21 days of either unpredictable chronic stress (UCS) or no disturbance (control). Thereafter, all four ... -
Ecological and evolutionary consequences of ploidy-driven trait variation: Insights from Saxifraga oppositifolia L.
(Peer reviewed; Journal article, 2024)The ecological and evolutionary consequences of ploidy-driven trait variation, particularly for autopolyploids, remain poorly understood. <i>Saxifraga oppositifolia</i> L. (purple saxifrage), is a highly successful ... -
Directional epistasis is common in morphological divergence
(Peer reviewed; Journal article, 2024)Epistasis is often portrayed as unimportant in evolution. While random patterns of epistasis may have limited effects on the response to selection, systematic directional epistasis can have substantial effects on evolutionary ... -
Antler Allometry, the Irish Elk and Gould Revisited
(Journal article; Peer reviewed, 2024)The huge antlers of the extinct Irish elk have invited evolutionary speculation since Darwin. In the 1970s, Stephen Jay Gould presented the first extensive data on antler size in the Irish elk and combined these with ... -
Individual and temporal variation in movement patterns of wild alpine reindeer and implications for disease management
(Journal article; Peer reviewed, 2024)Animal behaviour is important for prevalence and outbreaks of infectious diseases, for instance by affecting individual interactions. Increasing the knowledge of individual movement patterns can provide better insight into ... -
Ecological & evolutionary role of resting metabolic rate in wild house sparrow populations
(Doctoral theses at NTNU;2024:426, Doctoral thesis, 2024)Ongoing environmental changes cause worldwide population declines. To better preserve biodiversity we must understand factors that contribute to population viability and persistence. For populations to persist under ... -
Environmentally driven changes in Atlantic salmon oxidative status interact with physiological performance
(Journal article; Peer reviewed, 2024)Farmed Atlantic salmon in sea cages experience natural seasonal changes in seawater temperature and photoperiod. Atlantic salmon have more oxidized tissues in spring and early summer, and this corresponds to the period of ... -
Reproductive performance of lumpfish (Cyclopterus lumpus, L. 1758) females: Effects of integrated photoperiod and temperature manipulations on sexual maturation and spawning
(Journal article; Peer reviewed, 2024)A successful control of sexual maturation is crucial for year-round production of lumpfish juveniles destined as cleaner fish in Atlantic salmon aquaculture. This study investigated the combined effects of photoperiod and ... -
Evaluation of cell viability, CYP1A activity and genotoxic effects following exposure to ternary mixtures of benzo(α)pyrene (B[α]P), 2,2',3,4,4',5'-hexachlorobiphenyl (PCB 138) and perfluorooctane sulfonic acid (PFOS) in H4IIE rat hepatoma cells
(Master thesis, 2024)Polysykliske aromatiske hydrokarboner (PAH), polyklorerte bifenyler (PCB) og per- og polyfluorerte alkylstoffer (PFAS) er tre klasser av utbredte miljøgifter som kan forekomme sammen i komplekse blandinger. Disse kjemikaliene ... -
Integrated approaches to sustainable waste management in Norwegian aquaculture: Nutrient upcycling, bioremediation, and production potential of Hediste diversicolor (OF Müller, 1776) (Annelida: Nereididae) cultivated using aquaculture sludge from Atlantic salmon (Salmo salar L.) production
(Doctoral theses at NTNU;2024:434, Doctoral thesis, 2024)English summary Future growth of the Norwegian Atlantic salmon (Salmo salar L.) industry will, among others, depend on the continued supply of feed ingredients, improved resource utilization, and sustainable management ... -
Degradation of Plastic Consumer Products: From Macro- to Micro- and Nanoplastics
(Master thesis, 2024)Miljømessig plastforurensning består av delvis nedbrutte partikler i forskjellige størrelser, former, polymertyper og kjemiske sammensetninger. På grunn av potensialet for biologisk opptak, anses mikroplast og nanoplast ... -
Testing the sensitivity of Phaeodactylum tricornutum to environmental conditions and pollutants
(Master thesis, 2024)Kiselalger har betydelig økologisk betydning som primærprodusenter da de er ansvarlige for mer enn 20% av global karbonfiksering og er viktige komponenter i den marine næringskjeden. Deres unike egenskaper gjør dem til ... -
Investigating the effects of sea temperature and herring quality on Atlantic puffin productivity in the Norwegian Sea
(Master thesis, 2024)Seabirds are restricted to forage within the vicinity of their breeding colony during the breeding season and are therefore sensitive to localized prey depletion. Responses to prey depletion, in the form of reduced ... -
Tolerance of the marine microalga Phaeodactylum tricornutum to salinity and glyphosate-based herbicide
(Master thesis, 2024)Den robuste gruppen med kiselalger påvirkes direkte av den globale økte utslippen av klimagasser. Kiselalger kan utover deres industrielle anvendelser innen høy-volum lipid produksjon og bioteknologisk bruk, være en indikator ... -
Simulating the Thermal Regime and Surface Energy Balance of a Permafrost-Underlain Forest in Mongolia
(Peer reviewed; Journal article, 2024)Forests overlap with large parts of the northern hemisphere permafrost area, and representing canopy processes is therefore crucial for simulating thermal and hydrological conditions in these regions. Forests impact ... -
Expansion and validation of Boolean network model representing Basal Cell Carcinoma
(Master thesis, 2024)Basalcellekarsinom (BCC) er den mest utbredte formen for hudkreft, som oppstår fra det basale laget av epidermis. Logisk modellering, en beregningstilnærming innen systembiologi, tilbyr et kraftig verktøy for å avdekke ... -
Detection of a stress related acoustic signature by passive acoustic monitoring in Atlantic salmon farming
