Towards a genome wide understanding of salmon lipid metabolism gene regulation across tissues and life stages
(PhD Thesis;2019:40, Doctoral thesis, 2019)Atlantic salmon is an important source of essential omega-3 fatty acids in human diets; however, omega-3 content in farmed salmon has been decreasing over the past decade due to the replacement of fish oil in aquafeeds ... -
Towards increased use of IPM : an investigation of Norwegian grain farmers' pest management practices and decision processes
(Master thesis, 2018)The last decade, Integrated Pest Management (IPM) has become mandatory in many European countries, but implementation on farm level is lagging and evidence for the barriers and driving forces is lacking. The goal of 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 ... -
Towards sustainable food provisioning: An exploration of socio-material agencies shaping household shopping practices in Norwegian supermarkets
(Master thesis, 2021)The current agri-food system is intricate and immensely complex, with human and planetary health unravelling at an unimaginable pace. At its centre, grocery stores mediate the exchange of food items between farmers, ... -
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 ... -
