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 ...
Genomic characterization and phylogenetic position of two new species in Rhabdoviridae infecting the parasitic copepod, salmon louse (Lepeophtheirus salmonis)
(Public Library of Science, 2014-11-17)
Several new viruses have emerged during farming of salmonids in the North Atlantic causing large losses to the industry. Still the blood feeding copepod parasite, Lepeophtheirus salmonis, remains the major challenge for ...
Effects of reforestation and intensified land use on vascular plant species richness in traditionally managed hay meadows
(Finnish Botanical Publishing Board, 2003)
In this study of 130 sites with different management we investigated whether vascular plant species richness is significantly reduced when traditionally managed hay meadows are abandoned and reforested. We also compared ...
Verifisering av ein tredimensjonal bølgemodell ved hjelp av eksperimentelle data

Low Level Jet Streams at the Sea Ice Edge - Numerical Simulations using WRF
(The University of Bergen, 2013-06-03)
The goal of the presented thesis is to investigate the formation of low level jets at the sea ice edge. Differential heating creates very sharp fronts at the ice edge. A transversal circulation, initiated by altered pressure ...
Using behaviour of herring (Clupea harengus L.) to assess post-crowding stress in purse-seine fisheries
(The University of Bergen, 2014-05-30)
Within the purse-seine fishery crowding fish at high densities, during the process of slipping, has been shown to cause high mortalities. Mitigation measures are therefore needed to enable fishermen to avoid slipping fish, ...
Two Level Additive Schwarz Preconditioner For Control Volume Finite Element Methods
(The University of Bergen, 2010-09-22)
In this thesis we investigate nummerically the convergence properties of the control volume finite element method (CVFEM) preconditioned with a two level overlapping additive Schwarz method. Relevant theory regarding the ...
Extreme precipitation in Central Norway. A case and climate study
(The University of Bergen, 2010-06-01)
An extreme precipitation event occurred over Central Norway at the end of January to the beginning of February 2006. The heavy precipitation in addition to high temperatures lead to snow melt and increased run-off, which ...
Polygonalforkastninger - karakteristikk og dannelsesmekanismer. En studie basert på tolking av seismiske data fra Norske-Barentshavsmarginen
(The University of Bergen, 2014-09-22)
Polygonale forkastningssystemer (PFS) er bemerkelsesverdige strukturer som er identifisert i en rekke sedimentære bassenger over hele verden. Polygonalforkastninger er normalforkastninger med små sprang som hovedsakelig ...
Metagenomic analysis of ammonia-oxidizing archaea affiliated with the soil group
Ammonia-oxidizing archaea (AOA) have recently been recognized as a significant compo- nent of many microbial communities and represent one of the most abundant prokaryotic groups in the biosphere. H owever, only few ...
