Approaches to defining a planetary boundary for biodiversity
The idea that there is an identifiable set of boundaries, beyond which anthropogenic change will put the Earth system outside a safe operating space for humanity, is attracting interest in the scientific community and ...
Spatial Distribution of Seatrout Spawning and the Effects on Juvenile Abundance in River Teigdalselva, Western-Norway
(The University of Bergen, 2011-06-01)
The spatial distribution of seatrout spawning-grounds, microhabitat features and the resulting juvenile distribution were observed in a typical Western-Norwegian river. A total of 1870 squares within 187 cross-transects ...
Giving eyes to pelagic trawls: Acoustic and optical techniques measure behaviour, species, and sizes of fish in situ
(The University of Bergen, 2013-11-26)
Trawling, towing a cone-shaped net behind a moving boat, is a widespread fishing method both in commercial fisheries and to collect fish for scientific investigations. It combines filtering effect with herding behaviour ...
Effects of environmental conditions on culturing scallop spat (Pecten maximus)
(The University of Bergen, 2005-09-22)
The great scallop, Pecten maximus, is a valuable bivalve species attractive for human consumption. Scallop aquaculture is increasing, but availability of spat is a bottleneck to the development of a viable culture industry ...
Hormonal and Neuropeptide Mechanisms of Appetite Control in Atlantic Salmon
(The University of Bergen, 2010-06-25)
Estimating Fish Densities from Single Fish Echo Traces
(Bentham Open, 2009)
Estimating mean fish density per unit area has been done by counting single fish echo traces with a split beam echo sounder system in the open sea. A data program has been written that scans the acoustic signals for echo ...
Genome-wide DNA methylation profiling of non-small cell lung carcinomas
(BioMed Central, 2012-06-22)
Background: Non-small cell lung carcinoma (NSCLC) is a complex malignancy that owing to its heterogeneity and poor prognosis poses many challenges to diagnosis, prognosis and patient treatment. DNA methylation is an important ...
Measurements of Lesser sandeel schools (Ammodytes marinus) using omnidirectional fisheries sonar
(The University of Bergen, 2012-09-03)
The coverage of this master thesis is 58 pages, with 25 Figures and 9 Tables. The Simrad SH90 high frequency omidirectional sonar was used in a field experiment in 2011 to acoustically investigate the distribution of Lesser ...
Analyses of Thermotogales secretomes
(The University of Bergen, 2014-08-04)
The aim of this study was to analyse the secretomes of the deeply branching order Thermotogales, using the species of Thermosipho africanus, Petrotoga mobilis, and Kosmotoga olearia, which have all been isolated from hot ...
Protozan ectosymbionts on Atlantic salmon (Salmo salar L.) in a Hatchery in Hordaland, Western Norway: Morphology and Epizootiology
(The University of Bergen, 2003)
Protozoan ectosymbionts are commonly found on salmonids in Norwegian lakes and rivers. Salmon in hatcheries supplied with water from such watercourses are often infected with such organisms. Despite extensive salmon ...
