Key genes and regulators associated with sexual differentiation and gonad development in Atlantic cod (Gadus morhua L.)
(Doctoral thesis; Doktorgradsavhandling, 2012-02-17)
Atlantic cod (Gadus morhua L.) is a promising cold-water aquaculture species, but early sexual maturation is a major problem in today’s cod farming. Teleosts display a wide variety of sex determination and sex differentiation mechanisms, ranging from genetic to environmental factors and the sexual plasticity in gonads and brain possibly reflects on a combination of these. From a practical point of ...
Management of the alien invasive red king crab Integrating natural and social science perspectives
(Doctoral thesis; Doktorgradsavhandling, 2012-06-12)
The red king crab (Paralithodes camtschaticus) is a highly valuable resource that also represents a potential threat since it is an alien invasive species in the Barents Sea ecosystem. This thesis explores the use of different interdisciplinary frameworks to analyse how ecological, social and economic concerns could be accounted for in deciding on how the king crab should be managed in the Norwegian ...
Metabolic fingerprinting applied in diatom taxonomy
(Doctoral thesis; Doktorgradsavhandling, 2012-06-18)
The main aim of this thesis was to investigate if and how metabolic fingerprinting can be applied in diatom taxonomy. Even though both morphology and gene sequences have been shown to be appropriate tools in diatom taxonomy there are cases where these give contradicting results, like in the case of cryptic species. Cryptic species have similar morphology but are genetically different. Another issue ...
Plant regulatory networks : RNA binding proteins as mediators of communication between DNA containing compartments by dual targeting
(Doctoral thesis; Doktorgradsavhandling, 2012-05-11)
The endosymbiosis-derived organelles within a plant cell, plastids and mitochondria, have to be equipped with a certain set of proteins to be fully functional. This set of proteins is encoded by different genomes: the organellar genomes and the nuclear genomes. This setup poses some interesting challenges for the regulation of gene expression and protein transport. On the one hand, the targeting ...
Technology transfer and R&D policy in a knowledge-based society
(Doctoral thesis; Doktorgradsavhandling, 2012-06-01)
Abstract
My thesis focuses on technology transfer and innovation policy in a knowledge-based society. In particular, I analyse the firms’ incentives to invest in research and development (R&D), the transfer of technological knowledge to a rival and government stimulation of R&D investment. Further, I analyse the incentives to engage in R&D cooperation in different market structures. By coordinating ...
Diversity along a speciation continuum : ecology and morphology of northern European whitefish (Coregonus lavaretus)
(Doctoral thesis; Doktorgradsavhandling, 2012-08-24)
How new species are formed is still a major question in evolutionary biology. In ecological speciation, natural selection drives the evolution of slight distinctions between individuals into extensive differences between species. In this thesis, early stages of an ecologically driven speciation process are addressed using ecological and morphological data from a large number of European whitefish ...
Making Sami Seascapes Matter : ethno-ecological governance in coastal Norway
(Doctoral thesis; Doktorgradsavhandling, 2012-06-22)
This thesis addresses the lack of knowledge production on impacts of new marine industries on coastal Sami culture in the Norwegian coastal zone. It asks how Sami culture matters in contemporary Norwegian marine governance, and discusses how ecosystem mapping practices facilitate knowledge production on Sami relations and use of the marine environment. This is done through five papers and a film, ...
På grensen til et eventyr : økonomisering av Snøhvit LNG
(Doctoral thesis; Doktorgradsavhandling, 2012-06-29)
Megaprosjekter er store investeringsprosjekter med betydelig innflytelse på samfunn, miljø og økonomi. Til tross for grundige utredninger og beregninger i forkant, presterer slike prosjekter sjelden i overenstemmelse med planene: de blir gjerne både forsinket og mye dyrere enn estimatene tilsa. Hva er det som skjer i megaprosjekter som gjør at planer om suksess blir til fortellinger om fiasko? Dette ...
Hunter's behavioural responses to changes in bag size and willow grouse density : implications for management and interpretation of harvest data
(Doctoral thesis; Doktorgradsavhandling, 2012-12-19)
An important aspect of ecological research is to provide guidelines and tools to wildlife managers. The ecological feature of density dependence which shapes population responses to harvest are important for wildlife management, but monitoring practices and exploiter dynamics to the changing resources and management regimes should also be included. Bag records are often collected by wildlife managers ...
Female life-history parameters in the introduced red king crab (Paralithodes camtschaticus, Tilesius 1815) in the Barents Sea : a study of temporal and spatial variation in three Norwegian fjords.
(Doctoral thesis; Doktorgradsavhandling, 2012-08-28)
The red king crab (Paralithodes camtschaticus) was deliberately introduced to the Barents Sea by Russian scientists during the 1960s, with the purpose to improve coastal fishery and thus improve the local economy. Since the red king crab was caught for the first time in the Varangerfjorden area, the stock has increased in abundance and expanded westward inhabiting coastal areas along the coast of ...
