Termisk behandling om vinteren som ledd i bekjempelsesstrategi av parkslirekne (Reynoutria japonica)
(Master thesis, 2023)Fremmede invaderende arter er en av de største truslene mot biologisk mangfold, og gir store økologiske og økonomiske konsekvenser. Parkslirekne (Reynoutria japonica) er en av de verste fremmede artene verden over, og den ... -
The domestication of Oreochromis mossambicus in a breeding program in Mozambique
(Master thesis, 2018)This study describes the establishment of a baseline and a base camp for the development of a genetic enhancement program for the Mozambique tilapia, Oreochromis mossambicus, with the scope of utilising both additive and ... -
The effect of feeding routines on lions and tigers in a zoo environment
(Master thesis, 2023)Denne studien hadde som mål å undersøke effekten av to ulike fôringsrutiner på adferden til løver (Panthera leo melanochaita) og tigre (Panthera tigris tigris) i et dyreparkmiljø. Fôringsrutinene som ble vurdert, involverte ... -
The Effect of Red/Blue Light and CO2 Enrichment on Development, Photosynthesis, Yield and Quality of Vicia faba Grown in Controlled Environment
(Master thesis, 2024)There is a need to explore new methods of food production as effects of climate change influence yield and quality of crops in field production. Higher frequency of extreme weather, new diseases and insect pests, in addition ... -
The effect of tetradecylthioacetic acid (TTA) on body weight management in growing silver foxes (vulpes vulpes) as a model for dogs (Canis familiaris)
(Master thesis, 2018)This thesis consists of two parts, one general part concerning obesity and obesity related health problems in dogs. In addition, the general part gives an overview of methods to prevent obesity with restricted energy intake, ... -
The effects of dietary EPA and two production systems (RAS & FT) on growth and lipid class compositions of gills of Atlantic salmon (Salmo salar)
(Master thesis, 2023)Recirculating aquaculture systems (RAS) are becoming quite common for commercial production of large post smolts, primarily because of their potential for sustainable use of water, better control over culture conditions ... -
The effects of environmental enrichments, group size and confinement length on play behaviour in juvenile Norwegian dairy goats (Capra hircus)
(Master thesis, 2018)Lek blir ofte betraktet som en indikator på god velferd i unge pattedyr siden det sjelden forekommer under vanskelige forhold. Det vil derfor være nyttig å vite hvordan endringer i noen normale produksjonsforhold påvirker ... -
The role of age in the selection of police patrol dogs using a standardized behavior test
(Master thesis, 2019)Police patrol dogs face many challenging situations, and only a proportion of dogs are suitable for this work. It is desirable to identify suitable dogs as early as possible, allowing unsuited dogs to be released for other ... -
The suitability of using FAO’s Tool for Agroecological Performance Evaluation (TAPE) in a Norwegian context
(Master thesis, 2022)The present agri-food system, in Norway and globally, is facing severe challenges when it comes to ecological, economic, and social sustainability. To retain the presumptions for future generations to flourish on earth, ... -
The use of polytunnels to study the effect of drought stress and increased temperature on spring wheat.
(Master thesis, 2023)An increase in wheat production will be vital to feed a growing population. Heat and drought are already causing great losses in yield, and climate change is expected to damage production in the future. Breeding for drought ... -
The use of Saccharomyces cerevisae CNCM I-1077 in feed for ruminants : effect on digestibility, rumen enviroment and methane emmission
(Master thesis, 2019)The main objective of this experiment was to evaluate the effect of adding live yeast (Saccharomyces cerevisiae CNCM I-1077) in rations to dairy cows in early lactation on apparent total tract digestibility, rumen physiological ... -
Tipburn in lettuce (Lactuca Sativa L. ´Frillice´) : identifying climate factors that induce tipburn and cultivation methods that mitigate tipburn in controlled environment
(Master thesis, 2019)This master thesis is done with the aim of adding understanding to why tipburn occurs in greenhouse production of ´Frillice´ lettuce (Lactuca Sativa L. ’Frillice’), and to find cultivation methods can help reduce this ... -
Towards pesticide free agriculture in the Pilat Rhodanien, France : a socio-technical systems analysis into barriers and opportunities on a territorial scale
(Master thesis, 2022)This research was conducted as part of the first phase of a 6-year long project run by INRAE called “Be Creative” (2021-2026). The project’s ambition is to study specific agricultural territories in France in view of ... -
Tracking GnRH neurons in vivo following CRISPR knock out of Six6 in Atlantic salmon
(Master thesis, 2021)Gonadotropin releasing hormone (GnRH) is a conserved neuroendocrine decapeptide, crucial for the onset of puberty and for the functioning of the hypothalamic-pituitary-gonadal axis (HPG). The homeodomain protein sine oculis ... -
Transfection optimization and gene editing method establishment for fish cells
(Master thesis, 2021)Aquaculture is one of the fastest-growing industries around the world, and salmonoid aquaculture is a very big industry for Norway. Ensuring fish health and welfare is essential for aquaculture, also to avoid economic loss. ... -
Transposable Elements as a Source of Novel Gene Regulation in Atlantic Salmon (Salmo salar)
(Master thesis, 2021)It has become evident over the last decade that transposable elements play an extensive role in gene regulatory evolution. Their ability to transpose close to genes, while also acting as cis-regulatory elements, permits ... -
Trends in runs of homozygosity and inbreeding in Norwegian Red Cattle before and after implementation of genomic selection
(Master thesis, 2020)Background: Despite commercial breeding being part of the genomic era, routine use of genotype data to govern inbreeding is still scarce. Recent studies have found acceleration of inbreeding rates after implementation of ... -
Unraveling the genetic mysteries of the Norwegian Fjord-horse : identifying harmful haplotypes for improved breeding strategies
(Master thesis, 2023)Fertiliteten til avlsdyrene er særdeles kritisk i små populasjoner med høy innavl. Fjordhest-populasjonen i Norge består av få stamfedre, og er blitt registrert til å ha en lavere føllings-rate enn flere andre hesteraser. ... -
