An Unaccounted Fraction of Marine Biogenic CaCO3 Particles
(Public Library of Science, 2012-10-23)
Biogenic production and sedimentation of calcium carbonate in the ocean, referred to as the carbonate pump, has profound implications for the ocean carbon cycle, and relate both to global climate, ocean acidification and ...
Cell cycle regulation of Oikopleura dioica. A study of the cyclin CDK-complement
(The University of Bergen, 2014-11-14)
<p>Regulation of the eukaryotic cell cycle is a fundamental biological process which controls proliferation of all eukaryote cells. Progression through the cell cycle is highly dependent on its core regulators; Cyclins and ...
Indiscriminately Loving Sticklebacks. A test of assortative mate preferences between two morphologically diverged parapatric populations of threespine stickleback (Gasterosteus aculeatus L.) concerning pelvic reduction
(The University of Bergen, 2013-06-07)
Two parapatric populations in western Norway in which one have completely reduced its pelvic complex are tested for assortative mating being an important mechanism in maintaining barriers keeping them from mixing in ...
Multi-frequency acoustic discrimination between gas bubble plumes and biological targets in the ocean
(The University of Bergen, 2015-06-18)
<p>Seabed-originating gas bubble seeps have been observed worldwide from a variety of sources (e.g. Hovland and Judd, 1988) and are most frequently composed of methane and carbon dioxide. Some seabed gas leaks, such as ...
Dive to survive: effects of capture depth on barotrauma and post-release survival of Atlantic cod (Gadus morhua) in recreational fisheries
(Oxford University Press, 2015-06-04)
Atlantic cod (Gadus morhua) caught in recreational fisheries are commonly released, often with barotrauma after rapid decompression. Mouth-hooked, non-bleeding cod kept in a floating net pen showed mortalities ≥40% when ...
Copepods enhance nutritional status, growth and development in Atlantic cod (Gadus morhua L.) larvae – can we identify the underlying factors?
The current commercial production protocols for Atlantic cod depend on enriched rotifers and Artemia during first-feeding, but development and growth remain inferior to fish fed natural zooplankton. Two experiments were ...
Climate warming causes life-history evolution in a model for Atlantic cod (Gadus morhua)
(Oxford University Press, 2014)
Climate change influences the marine environment, with ocean warming being the foremost driving factor governing changes in the physiology and ecology of fish. At the individual level, increasing temperature influences ...
Escape mortality of cod, sithe and haddock in a Barents Sea trawl fishery
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 ...
Macrozooplankton as feed source for farmed fish - growth, product quality and safety
(The University of BergenInstitute of Marine Research, 2006-12-14)
Centennial changes in water clarity of the Baltic Sea and the North Sea
Secchi depth is a valuable proxy for detecting long term changes in the water clarity of oceanic and coastal ecosystems. We analyse approximately 40 000 observations, which are available from ICES, from the Baltic Sea and ...
