Experimental parameterisation of principal physics in buoyancy variations of marine teleost eggs
(Public Library of Science, 2014-08-14)
It is generally accepted that the high buoyancy of pelagic marine eggs is due to substantial influx of water across the cell membrane just before ovulation. Here we further develop the theoretical basis by applying laboratory ...
Does snail grazing affect growth of the old forest lichen Lobaria pulmonaria?
(Cambridge University Press, 2006)
Grazing marks from snails are frequently observed in populations of the old forest epiphyte Lobaria pulmonaria. However, grazing marks are more numerous in thalli from deciduous broadleaved forests than in thalli from ...
Decontamination of persistent organic pollutants in fishmeal and fish oil. Process optimization and modeling
(The University of Bergen, 2011-10-07)
Persistent organic pollutants (POPs) are fat soluble chemical substances that persist in the environment and bioaccumulate in the food chain. Through long-range environmental transportation by air, water and migratory ...
Investigation of the possibilities for seabottom characterization using echosounder data
(The University of Bergen, 2009-11-18)
This thesis focuses mainly on using the information present in the first echo returned from the seafloor, using a normal-incidence echosounder, to characterize or classify the seabed. This is done using a monostatic setup ...
Herring (Clupea harengus) in Lindåspollene before and during spawning: spatial decisions and school dynamics
(The University of Bergen, 2011-06-01)
Abstract This study reports on the school dynamics of a self-sustained local population of Atlantic herring (Clupea harengus) in Lindåspollene, south-western Norway, during pre-spawning and spawning, observed over a period ...
Vertically Averaged Models for CO2 Storage in Porous Media

Seedbank, Seedrain and Seedling Recruitment along Climate Gradients in Southern Norway
(The University of Bergen, 2010-06-01)
Recruitment through seeds is a critical process in the life history of plants. Better knowledge about this process may be helpful in predicting species ranges and range shifts under climate change. In western Norway, ...
Gene expression analyses of immune responses in Atlantic salmon during early stages of infection by salmon louse (Lepeophtheirus salmonis) revealed bi-phasic responses coinciding with the copepod-chalimus transition
The salmon louse (Lepeophtheirus salmonis Krøyer), an ectoparasitic copepod with a complex life cycle causes significant losses in salmon aquaculture. Pesticide treatments against the parasite raise environmental concerns ...
A discussion on turbulent and undular bores using the models from the shallow water equations and the dispersive system.
(The University of Bergen, 2010-05-26)
The bore is a wave phenomenon that occurs in channels and rivers of shallow water. Referred to as a discharge wave, a bore is generated by a sudden increase of water flow. Bores appear in certain rivers as the tide pushes ...
