Sustainable production of high quality Atlantic salmon fillets
(Master thesis, 2013-09-10)The aim of study was to identify the effect of Atlantic salmon (Salmo salar) energy status in the late summer on fat accumulation in the autumn, and to investigate whether it is possible to improve ... -
Sweet potato production in South Sudan : current status, virus infections and whitefly vector diversity
(PhD Thesis;2019:98, Doctoral thesis, 2019)Sweet potato (Ipomoea batatas (L.) Lam.) is an important staple food crop that assures food security in sub-Saharan Africa, especially East Africa. In South Sudan, sweet potato is a main staple food crop for many farming ... -
Sweet potato virus in Ethiopia : detection, characterization, elimination and management
(PhD Thesis;2019:94, Doctoral thesis, 2019)The initiative to improve sweet potato production and productivity in Ethiopia began in the 1980s and so far, there are 26 improved sweet potato varieties made available for farmers. Lack of a rigorous quarantine scheme ... -
Swiss agricultural policy and the goal of multifunctionality : what experiences can be drawn?
(Master thesis, 2017)After the Second World War, a productivist focus has led to agricultural policy stimulating intensification of agriculture, creating overproduction and environmental problems. As a reaction, ‘multifunctionality’ became an ... -
Søk etter DNA-variasjon som virker inn på resistens mot infeksiøs pankreasnekrose (IPN) i Atlantisk laks (Salmo salar)

Taming nitrogen : recognizing N2O emissions in fertilization practice
(Master thesis, 2016-08-11)Atmospheric nitrous oxide (N2O) is a greenhouse gas resulting from an imbalanced global nitrogen cycle. Although agricultural soils emit the majority of anthropogenic N2O, it is rarely considered in soil management practice. ... -
Tap av sau og lam på utmarksbeite – effekt av beitekvalitet og rovdyrførekomst i utvalde skogs- og fjellkommunar
(Master thesis, 2022)Dei siste ti åra har i gjennomsnitt omlag 91 000 sau og lam blive borte kvar sommar på utmarksbeite. Dette fører til produksjonstap for bonden og det er eit dyrevelferdsproblem. Årsakssamanhengane er ofte uklare og komplekse. ... -
Technical and economic analysis of farming systems engaged in Agri-Environment-Climate measures for pesticide use reduction in Burgundy (France)
(Master thesis, 2019)The European Union has created agri-environmental measures so that some of the European farmers may commit to reducing their environmental impact in exchange for financial compensation. However, little is known about the ... -
The temporal expression pattern of MND1 and key regulators of floral transition in annual and perennial Pooideae species
(Master thesis, 2021)The molecular mechanisms underlying differences in annual and perennial life-history strategies are poorly understood. However, studies have shown that perennials often exhibit delayed flowering compared to related annuals. ... -
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 ... -
Terroirs comparison in terms of biomass flows and nitrogen balance : study case of Diohine and Barry Sine in the former groundnut basin
(Master thesis, 2014-02-17)Physical, socio-political and economical changes impacted the former Senegalese groundnut basin what resulted in a strong natural resources use competition and therefore an agrarian transition that disconnects cropping and ... -
Tetradecylthioacetic acid (TTA) : a functional feed ingredient for Atlantic salmon affecting early sexual maturation, cardiac robustness and β-oxidative capacity
(PhD Thesis;2018:36, Doctoral thesis, 2018)Utilisation of fatty acids highly dominates energy metabolism in high performance fish as the Atlantic salmon. It is well established knowledge that feed intake and growth of salmon is highly influenced by water temperature ... -
Tetradecylthioacetic acid (TTA) – A functional feed ingredient for Atlantic salmon (Salmo salar L.): Growth, sexual maturation and health
(PhD Thesis;2010:23, Doctoral thesis, 2010)Farmed Atlantic salmon (Salmo salar L.) is transferred to sea at different times during the year. Independently of time after sea transfer, the salmon experience a period of low performance, characterized by reduced appetite, ... -
The accuracy of across population genomic predictionusing a Bayesian variable selection model
(Master thesis, 2015-11-05)Background: The use of information across populations is an attractive approach to increase the accuracy of genomic prediction for numerically small populations. However, accuracies of across population genomic prediction, ... -
The accuracy of genomic prediction for viral nervous necrosis and vibrosis disease resistance in atlantic cod
(Master thesis, 2014-09-18)The objective of this study was to estimate accuracy of genomic prediction for disease resistance to viral nervous necrosis and vibriosis using sparse and genome sequence SNP-data in Atlantic cod. The disease challenge ... -
The domestic fair trade movement in France, a bottom-up regulation?
(Master thesis, 2016-03-07)Over the last two decades, alternative food systems have been developing quickly. Recently, the convergence between the fair trade sector and the growing demand for local products, has participated to the development of a ... -
