Impact of agricultural landscape on honey reserves in bee colonies
(Master thesis, 2016-11-23)Intensive farming systems are now scarce floral environments leaving honey bees with low food availability at some periods. This scarcity could be related to the current recorded honeybee and wild pollinator decline. ... -
The effect of Laminaria hyperborea and its bioactive components on the intestinal health of Atlantic salmon
(Master thesis, 2016-11-23)The rapid expansion of the aquaculture industry is imposing an increasing demand on the available feed resources for aquafeeds, particularly fishmeal. Plant-derived ingredients have been widely investigated in recent years ... -
Identifying inoculation methods for screening of resistance to Fusarium langsethiae in selected oat varieties
(Master thesis, 2016-11-22)F. langsethiae is reported as the main producer of HT-2+T-2 toxins in Norwegian oats (Hofgaard et al., 2016). This investigation aimed to identify whether ranking of oat varieties according to the content of HT-2+T-2 toxins ... -
Doing Agroecology : democratic practice and social learning in civic food organizations
(Master thesis, 2016-11-22)Localization of food networks has been heralded as a way of creating a more just and sustainable food system. This study explores the potential of civic food networks to serve as sites for “really existing” food democracy, ... -
Participatory video in agroecology education : a multiple-case study with the Green Learning Network
(Master thesis, 2016-11-22)A transformation of our food system necessitates a revision of how we think and communicate about agriculture. In the past few decades, increasing attention has been paid to the unique requirements of teaching sustainable ... -
The growth and development of lettuce, coriander and swiss chard in a cold water aquaponic system optimized for lettuce production
(Master thesis, 2016-11-17)Aquaponic research seemed to be characterized by experiments conducted in warm water systems while experiments in cold water systems were almost non-existent per August 2016. The main aim of this thesis was therefore to ... -
Påvirker fôropptak hos Niltilapia eller en forurenset algekultur Chlorella sorokiniana’s kapasitet som biofilter?
(Master thesis, 2016-11-16)Den encellede grønnalgen Chlorella sorokiniana har potensial til å erstatte konvensjonell bruk av nitrogenoksyderende bakterier i biofilter for å fjerne ammoniakk fra fiskens proteinkatabolisme i resirkulerte akvakultursystemer ... -
Fett og omega 3 til hest : kilder, potensiell virkning og bruksområde
(Master thesis, 2016-09-07)Bruk av mer fett i fôr til hest har i nyere tid blitt vanligere enn før. Fett gir en mulighet til å øke energikonsentrasjonen i fôret, og samtidig redusere inntaket av NSC, som sukker og stivelse. Mange hester er avhengig ... -
