High Arctic Invertebrate Biogeography. Patterns and Colonization Processes since the Last Glacial Maximum
(The University of Bergen, 2011-09-22)
The biogeography of Arctic terrestrial invertebrate species, and particularly processes creating and determining patterns of species distribution, have rarely been considered as a whole, but rather on a regional basis, ...
Microbiological aspects of fish handling and processing in the Norwegian pelagic sector
(The University of Bergen, 2015-03-17)
Most global marine fish resources seem to have reached their limit of sustainable exploitation, whereas the demand for high quality fish products is still increasing. The fish sector needs to comply with the growing market ...
Mechanisms of cataract development in adult Atlantic salmon growers relative to dietary histidine and plant feed ingredients
(The University of Bergen, 2010-03-19)
Cataracts are defined as opacities of the eye lens and can be caused by a large number of risk factors. In aquaculture, cataracts in farmed Atlantic salmon (Salmo salar L.) represent an ethical problem and can cause ...
Radiometrically determined dates and sedimentation rates for recent sediments in nine North African wetland lakes (the CASSARINA Project)
Sediment cores were collected from nine wetland lakes in Morocco, Tunisia and Egypt for the CASSARINA project investigating environmental change in Northern African wetlands. The cores were dated radiometrically by using ...
Characterization of the Atlantic cod (Gadus morhua L) eggs for estimation of spawning time and proportion of spawning females
(The University of Bergen, 2011-05-29)
A set of eggs from first time spawning Atlantic cod (Gadus morhua L) was investigated for the understanding of variations in egg sizes, e.g. with time in the spawning season, daily inter and intra variations, daily ...

Back to Africa: monitoring post-hydropower restoration to facilitate reintroduction of an extinct-in-the-wild amphibian
(Ecological Society of America, 2014-08-11)
Monitoring of the ecological efficiency of different restoration and mitigation measures is important to inform decision-making but can be challenging, especially in remote and low-resource settings. Species composition ...
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 ...
Taxonomic overview of calcareous sponges (Porifera, Calcarea) in the Jan Mayen vent field at the Mohn Ridge
(The University of Bergen, 2013-12-17)
The Porifera is a very old group of organisms that has been dated back to more than 500 million years. They are important to marine benthic communities by providing protection, contributing to nutrient recycling and ...
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 ...
