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. ... -

(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 ... -
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 biochemical parameters on tenderness in beef
(Master thesis, 2012-09-06)The tenderness of beef is determined by the degree of myofibrillar toughness and content of insoluble collagen. The myofibrils and connective tissue and their degradation is largely determined by the amount of proteases ... -
