Effects of environmental stress on mRNA expression levels of seven genes related to oxidative stress and growth in Atlantic salmon Salmo salar L. of farmed, hybrid and wild origin
(BioMed Central, 2012-12-05)
<p>Background: Ten generations of domestication selection has caused farmed Atlantic salmon Salmo salar L. to deviate from wild salmon in a range of traits. Each year hundreds of thousands of farmed salmon escape into the ...
Co-infection with Norwegian Salmonid Alphavirus (NSAV) and Infectious Pancreatic Necrosis Virus (IPNV) in Chinook Salmon Embryo Cells (CHSE-214).
(The University of Bergen, 2009-06-02)
Infectious pancreatic disease (IPN) and pancreas disease (PD) of salmon are viral diseases caused by Infectious Pancreatic Necrosis Virus (IPNV) (Birnaviridae) and Salmonid Alphavirus (SAV) (Togaviridae). Both IPNV- and ...
The rise and fall of forests

Stochastic dynamics of interacting haematopoietic stem cell niche lineages
Since we still know very little about stem cells in their natural environment, it is useful to explore their dynamics through modelling and simulation, as well as experimentally. Most models of stem cell systems are based ...
Lifespan extension in a semelparous chordate occurs via developmental growth arrest just prior to meiotic entry
It is proposed that the ageing process is linked to signaling from the germline such that the rate of ageing can be adjusted to the state of the reproductive system, allowing these two processes to co-evolve. Mechanistic ...
Effects of genetic complexity and time resolution in an individual-based model of mesopelagic fish with hunger and fear
(The University of Bergen, 2014-06-02)
Many studies have shown that emotion systems are in use to direct behavior, which has also been utilized in a recent mathematical model. To investigate the general validity on the results from this model for vertical ...
Environmental manipulation of land-based farmed Arctic charr; effects on growth, feeding and maturation
(The University of Bergen, 2014-05-08)
<p>Farming of Arctic charr takes mainly place in land-based farms applying intensive rearing methods with relatively high production costs. Depending on local conditions at each site, it is possible to regulate important ...
Prevalence of infectious salmon anaemia virus (ISAV) in wild salmonids in western Norway
Studies of infectious salmon anaemia virus (ISAV), an important pathogen of farmed salmon in Norway, Scotland, the Faeroe Islands, Ireland, Canada, the USA and Chile, suggest that natural reservoirs for this virus can ...
Transcriptome sequencing of Atlantic salmon ( Salmo salar L.) notochord prior to development of the vertebrae provides clues to regulation of positional fate, chordoblast lineage and mineralisation
(BioMed Central, 2014-02-19)
<p><strong>Background</strong> In teleosts such as Atlantic salmon (Salmo salar L.), segmentation and subsequent mineralisation of the notochord during embryonic stages are essential for normal vertebrae formation. However, ...
Holocene environmental and climate history of Trettetjørn, a low-alpine lake in Western Norway, based on subfossil pollen, diatoms, oribatid mites, and plant macrofossils
(The Institute of Arctic and Alpine Research, University of Colorado, 2006)
Holocene lake and catchment environmental history and regional climate are reconstructed from lake sediments at Trettetjørn, a small lake situated close to the present-day treeline in western Norway. Sediments began to ...
