Herring (Clupea harengus) in Lindåspollene before and during spawning: spatial decisions and school dynamics
(The University of Bergen, 2011-06-01)
Abstract This study reports on the school dynamics of a self-sustained local population of Atlantic herring (Clupea harengus) in Lindåspollene, south-western Norway, during pre-spawning and spawning, observed over a period ...
Seedbank, Seedrain and Seedling Recruitment along Climate Gradients in Southern Norway
(The University of Bergen, 2010-06-01)
Recruitment through seeds is a critical process in the life history of plants. Better knowledge about this process may be helpful in predicting species ranges and range shifts under climate change. In western Norway, ...
Gene expression analyses of immune responses in Atlantic salmon during early stages of infection by salmon louse (Lepeophtheirus salmonis) revealed bi-phasic responses coinciding with the copepod-chalimus transition
The salmon louse (Lepeophtheirus salmonis Krøyer), an ectoparasitic copepod with a complex life cycle causes significant losses in salmon aquaculture. Pesticide treatments against the parasite raise environmental concerns ...
Finding a Needle in the Virus Metagenome Haystack - Micro-Metagenome Analysis Captures a Snapshot of the Diversity of a Bacteriophage Armoire
(Public Library of Science, 2012-04-11)
<p>Viruses are ubiquitous in the oceans and critical components of marine microbial communities, regulating nutrient transfer to higher trophic levels or to the dissolved organic pool through lysis of host cells. Hydrothermal ...
Life after fire: smoke and ash as germination cues in ericads, herbs and graminoids of northern heathlands
<p>Question: What is the impact of the fire cues smoke and ash on seed germination of important functional groups in the heathland system, namely ericads, herbs and graminoids? We predict that if germination from heathland ...
Review of ecosystem models of fjords; new insights of relevance to fisheries management
(The University of Bergen, 2001)
Fjords on the west coast of Norway contain small ecosystems that have similar physical and biological processes as large oceanic ecosystems. Hence, they are ideal experimental facilities. However, ecosystems are complex ...
Genome-wide analysis of the sox family in the calcareous sponge Sycon ciliatum: multiple genes with unique expression patterns
(BioMed Central, 2012-06-23)
<p>Background: Sox genes are HMG-domain containing transcription factors with important roles in developmental processes in animals; many of them appear to have conserved functions among eumetazoans. Demosponges have fewer ...
Germination ecology of the clonal grassland herb Knautia arvensis: Regeneration strategy and geographic variation.
(Opulus Press, 2003)
We investigated germination responses and seed recruitment in the clonal grassland herb Knautia arvensis (Dipsacaceae) throughout the species’ distributional range in Norway. Four predicted relationships between germination ...
Mitochondrial aquaporin-8-mediated hydrogen peroxide transport is essential for teleost spermatozoon motility
(Nature Publishing Group, 2015-01-14)
Reactive oxygen species (ROS), particularly hydrogen peroxide (H2O2), cause oxidative cell damage and inhibit sperm function. In most oviparous fishes that spawn in seawater (SW), spermatozoa may be exposed to harmful ROS ...
Trace metal concentrations in blue mussels Mytilus edulis (L.) in Byfjorden and the coastal areas of Bergen
