Whirly proteins as communicators between plant organelles and the nucleus?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2009)
Whirly proteins belong to a small family of proteins with a characteristic secondary structure and a conserved DNA binding domain that is found mainly in angiosperms. At least one member of the Whirly protein family, Whirly1, is dually targeted to the nucleus and to the chloroplasts and it was shown that apart from its initially described function as a transcriptional regulator of nuclear disease ...
Vertical movements of Atlantic salmon postsmolts relative to measures of salinity and water temperature during the first phase of the marine migration
(Journal article; Tidsskriftartikkel; Peer reviewed, 2009)
The migratory behaviour of hatchery-reared Atlantic salmon, Salmo salar L., post-smolts during the
first phase of the marine migration was examined to assess their susceptibility to salmon lice, Lepeophtheirus
salmonis (Krøyer), infestations. Swimming depths of eight post-smolts relative to the measured salinity and
temperature were monitored for an average of 11.4 h following release outside the ...

The Cyborgization of the Fisheries : on Attempts to Make Fisheries Management Possible
(Journal article; Tidsskriftartikkel; Peer reviewed, 2009)
Although natural resource exploitation has a long tradition, modern resource management is a more recent phenomenon. The huge variety in natural resource exploitation has made it difficult to place the industrial harvesting of marine living resources under political and managerial control. For most of history fish and fishing people have for all practical purposes been unmanageable.
From the late ...
Power and the Production of Science. Assessing Cod Stocks as the Mechanistic Fishery Collapses
(Journal article; Tidsskriftartikkel; Peer reviewed, 2009)
This paper discusses power relations in the production of knowledge
claims and the validation of management strategies. The experience of doing
stock assessment science and creating management plans for Canada’s east coast
cod fishery illustrates this general process. We demonstrate that the cyborgization
of fisheries-management is limited by its inability to produce power for stabilizing
the ...
Migratory behaviour and survival rates of wild northern Atlantic salmon (Salmo salar) post-smolts: effects of environmental factors
(Journal article; Tidsskriftartikkel; Peer reviewed, 2009-12-03)
To study smolt behaviour and survival of a northern Atlantic salmon (Salmo salar) population during river descent, sea entry and fjord migration, 120 wild S. salar were
tagged with acoustic tags and registered at four automatic listening station arrays in the mouth of the North Norwegian River Alta and throughout the Alta Fjord. An estimated 75% of the post-smolts survived from the river mouth, ...

Analysing diet of small herbivores : the efficiency of DNA barcoding coupled with high-throughput pyrosequencing for deciphering the composition of complex plant mixtures
(Journal article; Tidsskriftartikkel; Peer reviewed, 2009-08-20)
Background: In order to understand the role of herbivores in trophic webs, it is essential to know
what they feed on. Diet analysis is, however, a challenge in many small herbivores with a secretive
life style. In this paper, we compare novel (high-throughput pyrosequencing) DNA barcoding
technology for plant mixture with traditional microhistological method. We analysed stomach
contents of two ...
Spawning coloration and sperm quality in a large lake population of Arctic charr (Salmonidae: Salvelinus alpinus L.)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2009)
The modern theories of sexual selection predict that male sexual ornaments may have evolved as reliable signals of male fertilization efficiency. However, among the studies of fishes with external fertilization, the results have yielded ambiguous evidence. In the present study, we present data on the phenotypic relationships between red spawning coloration and ejaculate quality (spermatocrit, sperm ...
Gibberellin mediates daylength-controlled differentiation of vegetative meristems in strawberry (Fragaria × ananassa Duch)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2009-02-11)
Background: Differentiation of long and short shoots is an important developmental trait in
several species of the Rosaceae family. However, the physiological mechanisms controlling this
differentiation are largely unknown. We have studied the role of gibberellin (GA) in regulation of
shoot differentiation in strawberry (Fragaria × ananassa Duch.) cv. Korona. In strawberry,
differentiation of ...
