Taxonomic overview of calcareous sponges (Porifera, Calcarea) in the Jan Mayen vent field at the Mohn Ridge
(The University of Bergen, 2013-12-17)
The Porifera is a very old group of organisms that has been dated back to more than 500 million years. They are important to marine benthic communities by providing protection, contributing to nutrient recycling and ...
The morphology of the threespine stickleback and its relation to predators and parasites, from three lakes in western Norway
(The University of Bergen, 2011-06-01)
We studied the three-spined stickleback (Gasterosteus aculeatus) in three different lakes, with respect to morphology (Dorsal spine numbers and pelvis), distribution and relationship to the parasites Schistocephalus solidus ...
Tidleg utvikling av svømmeblæra hjå torskelarvar (Gadus morhua L.) frå intensivt oppdrett
(The University of Bergen, 2005)
Molecular characterisaton of T cell co-receptors CD3, CD8 and CD4 in Atlantic salmon (Salmo salar)
(The University of Bergen, 2009-03-27)
The commercial importance of Atlantic salmon (Salmo salar) in aquaculture has fuelled much research into fish health since outbreaks of infectious disease cause major financial losses. All aspects of immunology are ...
Effect of uneven sampling along an environmental gradient on transfer-function performance
We investigate the effect that uneven sampling of the environmental gradient has on transfer-function performance using simulated community data. We find that cross-validated estimates of the root mean squared error ...
Effects of Management on Heathland Vegetation in Western Norway
(The University of Bergen, 2009-03-31)
Aims: This synthesis of studies examines the effects of anthropogenic disturbance regimes; the traditional management practices of livestock grazing and prescribed burning, on vegetation and seed banks in coastal heathlands ...
The effects of leptin and ghrelin on voluntary feed intake and appetite in Atlantic salmon Salmo salar
(The University of Bergen, 2013-10-01)
Salmon farming has expanded dramatically in recent years, increasing the demand for both traditional feed ingredients and alternative proteins and oils. Developing new feed requires a deep understanding of appetite, ...
Competition of pathogens and probionts in cod yolk sac larvae measured in vivo, and the impact of increased temperature
(The University of Bergen, 2011-09-14)
Aquaculture are today one of the biggest food-producing sectors in the world. Over the recent decades there has been a great increase in intensity and commercialization of aquaculture production, which has led to an ...
Removing Noise From Pyrosequenced Amplicons
(BioMed Central, 2011-01-28)
Background: In many environmental genomics applications a homologous region of DNA from a diverse sample is first amplified by PCR and then sequenced. The next generation sequencing technology, 454 pyrosequencing, has ...
A bio-economic analysis of harvest control rules for the Northeast Arctic cod fishery
Harvest control rules (HCRs) have been implemented for many fisheries worldwide. However, in most instances, those HCRs are not based on the explicit feedbacks between stock properties and economic considerations. This ...
