(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, ...
Recent environmental change and atmospheric contamination on Svalbard as recorded in lake sediments – an introduction
This paper outlines an interdisciplinary project on recent environmental change and atmospheric contamination on the high Arctic archipelago of Svalbard (76º30'N – 80º30'N). It describes the rationale and aims of the project ...
Microalgal Bioprospecting. Spore swelling and germination as a bioassay for the rapid screening of crude algal extracts for antifungal activity
(The University of Bergen, 2006)
Microalgae and cyanobacteria has trough the last couple of decades been increasingly recognized as a valuable source of a variety of bioactive compounds. Many species have been investigated, but these represent mostly ...
Male reproductive biology of European hake Merluccius merluccius
(The University of Bergen, 2010-05-14)
The reproductive biology of European hake (Merluccius merluccius) has been studied extensively in the field, but mainly focusing on fecundity regulation in females and its implications for the fishery. The European hake ...
Taxonomic overview of calcareous sponges (Porifera, Calcarea) in the Jan Mayen vent field at the Mohn Ridge
(The University of Bergen, 2013-12-17)

Tracing recovery from acidification in the Western Norwegian nausta watershed
(Royal Swedish Academy of Sciences, 2003)
A novel method, redundancy analysis (RDA), has been used to examine whether chemical recovery from acidification in the western Norwegian Nausta watershed produces detectable recovery within the community structure of ...
Molecular characterisaton of T cell co-receptors CD3, CD8 and CD4 in Atlantic salmon (Salmo salar)
(The University of Bergen, 2009-03-27)
The commercial importance of Atlantic salmon (Salmo salar) in aquaculture has fuelled much research into fish health since outbreaks of infectious disease cause major financial losses. All aspects of immunology are ...
