Effects of dietary soybean meal, inulin and oxytetracycline on gastrointestinal histological characteristics, distal intestine cell proliferation and intestinal microbiota in Atlantic salmon (Salmo salar L.)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2007)
Soyabean meal (SBM)-induced enteritis in the distal intestine of the teleost Atlantic salmon (Salmo salar L.) and other salmonids may be considered a model for diet-related mucosal disorders in other animals and man. The role of the intestinal microbiota in its pathogenesis was explored. Compared to diets containing fishmeal (FM) as the sole protein source, responses to extracted SBM or the prebiotic ...
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 ...
Evaluating the impact of scoring parameters on the structure of intra-specific genetic variation using RawGeno, an R package for automating AFLP scoring
(Journal article; Tidsskriftartikkel; Peer reviewed, 2009-01-26)
Background: Since the transfer and application of modern sequencing technologies to the analysis of amplified fragment-length polymorphisms (AFLP), evolutionary biologists have included an increasing number of samples and markers in their studies. Although justified in this context, the use of automated scoring procedures may result in technical biases that weaken the power and reliability of further ...
Do Norwegian Atlantic salmon feed in the northern Barents Sea? Tag recoveries from 70 to 78 degrees N
(Journal article; Tidsskriftartikkel; Peer reviewed, 2008-01-13)
Three tagged Atlantic salmon Salmo salar were recaptured as subadults/adults (1.4 - 3 kg) between 70.5º - 78º N in the western Barents Sea; two of the fish originated from the Alta Fjord region in northern Norway and one from the Drammen River, south-eastern Norway. An additional tag was recovered from the stomach of a Greenland halibut captured south-west of Bear Island at >600m depth; this tag was ...
Management of reindeer husbandry in Norway – power-sharing and participation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2008)
Many governments have come to realize that the best way to manage natural resources is to include the resource users in order to increase legitimacy for governance. For the Sami reindeer industry, the Norwegian government has implemented two different management models in order to meet this challenge. On the one hand, there is a corporative management model where a few democratically elected reindeer ...
The distribution of chondrichthyans along the northern coast of Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2008-06-27)
The relationship between temperature, latitude, and depth and the distribution and relative abundance of chondrichthyans along the northern coast of Norway was examined based on catches made in scientific trawls north of 628N from 1992 to 2005. It appears that Chimaera monstrosa, Etmopterus spinax, Squalus acanthias, and Galeus melastomus were more abundant in the south, and Amblyraja radiata more ...
Effect of red and far red light on inhibition of hypocotyl elongation in ecotypes of Betula pendula Roth.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2005)
Failure of two consecutive annual treatments with ivermectin to eradicate the reindeer parasites (Hypoderma tarandi, Cephenemyia trompe and Linguatula arctica) from an island in northern Norway.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2002)
The highly efficient endectocide ivermectin is used to reduce the burden of parasites in many semidomestic reindeer herds in northern Fennoscandia. In the autumn of 1995 and 1996 all reindeer on the island of Silda (42 km2) were treated with ivermectin in an attempt to eradicate the warble fly (Hypoderma (=Oedemagena) tarandi (L.)), the nose bot fly (Cephenemyia trompe (Modeer)) (Diptera: Oestridae) ...
Nomadic pastoralism in the Aru basin of Tibet’s Chang Tang.
(Journal article; Peer reviewed; Tidsskriftartikkel, 2004)
Nomadic pastoralists live at the northern extent of human habitation within the ca. 5000 m elevation Aru basin, in the nortwestern part of the Chang Tang Nature Preserve, Tibet. These nomads herd primarily sheep and goats, a lesser number of yaks, and a few horses. Goats are increasing in importance because of the value of cashmere wool in national and international markets. Although sheep wool ...
Complete DNA sequences of the plastid genomes of two parasitic flowering plant species, Cuscuta reflexa and Cuscuta gronovii
(Journal article; Tidsskriftartikkel; Peer reviewed, 2007-08-22)
Background: The holoparasitic plant genus Cuscuta comprises species with photosynthetic capacity and functional chloroplasts as well as achlorophyllous and intermediate forms with restricted photosynthetic activity and degenerated chloroplasts. Previous data indicated significant differences with respect to the plastid genome coding capacity in different Cuscuta species that could correlate with ...
