Just Like Putting Scissors to a Market - Investigating Supply and Demand Relations of Farmed Atlantic Salmon
(Doctoral thesis; Doktorgradsavhandling, 2015-06-17)
Price and quantity numbers, which we are observing in a market place, occur because of an
interaction between supply and demand. An understanding of what drives supply and demand
is therefore important in order to understand the market in itself. This dissertation focuses on
determining the impact of exogenous factors on salmon biomass growth and how producers
respond to price changes. Furthermore, ...
Exploring social influences on children’s food attitudes and consumption
(Doctoral thesis; Doktorgradsavhandling, 2015-06-27)
Purpose: In light of the increasing numbers of overweight children observed today who follow inadequate diets, this dissertation mainly explored how children are socialised as food consumers. An additional purpose was to explore the advantages of using participatory photo interviews while researching children’s attitudes and behavioural patterns with respect to two food contexts, namely, lunch in ...
Taxonomic and functional approaches of trophic interactions between large herbivores and plant communities in a mountain ecosystem
(Doctoral thesis; Doktorgradsavhandling, 2015-12-08)
Given the key role of large herbivores on species and functional plant diversity, we aimed at better understanding the relationship between herbivory and plant communities mainly at a fine-scale, in order to reconcile objectives of population management and plant conservation. For this purpose, we used both taxonomic and functional approaches, and studied interactions at the inter- and intra-specific ...
Cyclically outbreaking geometrid moths in sub-arctic mountain birch forest: the organization and impacts of their interactions with animal communities
(Doctoral thesis; Doktorgradsavhandling, 2015-01-09)
In sub-arctic mountain birch forest in northern Fennoscandia, the 2 geometrid moth species Epirrita autumnata (autumnal moth) and Operophtera brumata (winter moth) show high-amplitude population cycles with regular 10-year periodicity. During some population peaks, moth populations attain outbreak densities and cause region-wide defoliation and mortality of mountain birch. The severity and duration ...

Spatial and temporal variations in parasite communities of freshwater fish in the subarctic
(Doctoral thesis; Doktorgradsavhandling, 2015-11-03)
Parasite communities are complicated systems believed to be affected by multiple ecological and environmental factors, both in time and space. These communities might be disrupted by anthropogenic host introductions which unfortunately appear to be a common practice e.g. in freshwater fish management. By addressing parasite occurrences in three of the most common freshwater fish species in subarctic ...

Emphasis was placed on exploring how cultural differences influence factors important in relationship satisfaction, how to attain the various factors, and how cultural differences are managed by buyers ...
Infectious pancreatic necrosis virus (IPNV) - Persistent infections, virulence and antiviral defence
(Doctoral thesis; Doktorgradsavhandling, 2015-02-06)
Infeksiøs pankreas nekrose (IPN) er en fiskesykdom som rammer mange fiskeslag over store deler av verden. Det har store økonomiske konsekvenser for norsk lakseoppdrettsnæring. Infeksiøs pankreas nekrose var først kjent som en sykdom i yngel, men i de siste 10 til 20 årene har det vært et like stort problem i post-smolt. Antall utbrudd varierer fra år til år, der 2009 ble registrert som et år med ...
