Notochord development in Atlantic salmon (Salmo salar L.): exploring molecular pathways and putative mechanism of segmentation
(The University of Bergen, 2014-03-07)
<p><strong>Background:</strong> A key feature of the vertebrate body plan is the repeated compartments made up of individual vertebra, blood vessels, peripheral nerves and muscle. The vertebral column comprises a series ...
Building Blocks of Sustainability in Marine Fisheries Management. Stakeholders, objectives, and strategies
(The University of Bergen, 2009-06-12)
Fisheries management, freshwater or marine, is found in virtually every country in the world. Fisheries management is the activity of organizing and controlling the extent of human exploitation of a single fish resource ...
CarboSchools - et utvannet klimaprosjekt eller et forbilde for gode feltstudier i biologi. En casestudie av en biologiklasses erfaringer og utbytte knyttet til CarboSchools prosjektet.
(The University of Bergen, 2010-12-20)
Sammendrag Internasjonale undersøkelser som TIMMS og PISA, samt søkertallene til høyere utdannelser har vist en negativ utvikling for realfagene både kunnskapsmessig og rekrutteringsmessig i løpet av 90-tallet og begynnelsen ...
Change and variation in a hyer-arid cultural landscape: A merhodological approach using remote sensing timeseries (Landsat MSS and TM, 1973-1996) from the Wadi vegetation of the eastern desert of Egypt
(The University of Bergen, 1999)
Nine wadi localities in a hyper-arid environment have been registered in the field and studied using earth observation data. Branch height, crown – and trunk – diameter, and indicators of land-use such as present traces ...
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 ...
