Deep chlorophyll a maxima (DCMs) in pelagic Antarctic waters. II. Relation to bathymetric features and dissolved iron concentrations
(Inter-Research, 2005-08-01)
A deep chlorophyll a maximum (DCM) at depths between 60 and 90 m in waters south
of the Antarctic Polar Front (APF) occurs only in pelagic waters where the chlorophyll a concentrations
in the upper mixed layer (UML) are ...
Nutrient pathways through the microbial food web: principles and predictability discussed, based on five different experiments
(Inter-Research, 2010-11-11)
Although explanatory and predictive powers are 2 closely interconnected aspects of
conceptual and mathematical models of complex systems, the two are not equivalent. The 2 aspects
are discussed here for the microbial ...
Escape mortality of cod, sithe and haddock in a Barents Sea trawl fishery
(Elsevier, 2006)
Experiments are described to investigate the survival of gadoid sh in the Barents
Sea escaping from a demersal trawl, with and without a sorting grid, at high and
low levels of shing intensity. The mortality for cod ...
Kanamycin resistens i det naturlige miljø i Sør-vest Norge; naturlig forekomst av aminoglykosid fosfotransferase (3) benyttet som markører i genmodifiserte organismer (GMO)
(The University of Bergen, 2014-04-11)
Sammendrag
Genmodifiserte organismer er vidt utbredt blant
verdens ledende matprodusenter. Bruk av
markørgener som koder for antibiotikaresistens er
vidt utbredt, særlig bruk av aph(3)-II /(npt-II).
Det er bred enighet ...
Bacterial community structures in the Arctic Ocean: the effect of increased carbon load on nutrient competition and bacterial diversity
(The University of Bergen, 2012-06-29)
The Arctic Ocean is a unique marine environment with respect to irradiation
periodicity and intensity, temperature, ice formation and strong stratification. Changes
due to global warming might be more pronounced in this ...
Potential impacts of abrupt in situ CO2 acidification on microbial abundance and community structure in deep-sea sediments
(The University of Bergen, 2013-06-05)
Studying the environmental impacts of CO2 leakage is important to evaluate the risk of sub sea CO2 storage. If there were possibilities that small amounts of CO2 would leak out, what would the environmental impact be on ...
“Is it important to consider males while measuring the reproductive potential of a fish stock?”
(The University of Bergen, 2008)
This study explored the paternal contribution to stock reproductive potential in Northeast
Arctic (NEA) cod (Gadus morhua L.). An equation for estimating total annual viable sperm
production (VSP) was parameterised for ...
Testosterone in feedback control of final maturation in female Atlantic cod - the effect of testosterone supplementation
(The University of Bergen, 2012-06-01)
Atlantic cod is a species of very high fecundity and it spawns rather easily and spontaneously in captivity. However husbandry routines, diets, females/males imbalances and stress are believed to be the causes of high ...
Pollination as an ecosystem service in Lofthus, Norway: A study on the distribution of wild and managed pollinators on apple crops and how they are affected by the surrounding landscape
(The University of Bergen, 2014-09-04)
Pollination is an important ecosystem service that
benefits human welfare by increasing the quantity
and quality of fruit and seed set of many crops.
The decline in bee abundance and diversity in
recent years may result ...
