Distribution of mesopelagic scattering layer (MSL) in relation to the physical environment in the Norwegian Sea
(The University of Bergen, 2014-06-02)
Mesopelagic fish are considered a major group of fishes in the global oceans and are typically observed in the water as acoustic scattering layers. Their biomass has recently been suggested to be severely underestimated, ...
Dynamic regulation of the transcription initiation landscape at single nucleotide resolution during vertebrate embryogenesis
(Cold Spring Harbor Laboratory Press, 2013)
Spatiotemporal control of gene expression is central to animal development. Core promoters represent a previously unanticipated regulatory level by interacting with cis-regulatory elements and transcription initiation in ...
Planctomycetes dominate biofilms on surfaces of the kelp Laminaria hyperborea
(BioMed Central, 2010)
Background: Bacteria belonging to Planctomycetes display several unique morphological and genetic features and are found in a wide variety of habitats on earth. Their ecological roles in these habitats are still poorly ...
Molecular characterisation of key components of the mucosal immune system in Atlantic salmon (Salmo salar L) and transcriptome analysis of responses against the salmon louse (Lepeophtheirus salmonis)
(The University of Bergen, 2012-04-17)
Mucosal immunity in mammals is mediated mainly by secretory immunoglobulin A (SIgA), which is produced by IgA plasma cells commonly located in the lamina propria, and a transport system involving the polymeric Ig receptor ...
Studies on the mitochondrial genome and rDNA genes from the salmon louse, Lepeophtheirus salmonis
(The University of Bergen, 2006-02-24)
An Unaccounted Fraction of Marine Biogenic CaCO3 Particles
(Public Library of Science, 2012-10-23)
Biogenic production and sedimentation of calcium carbonate in the ocean, referred to as the carbonate pump, has profound implications for the ocean carbon cycle, and relate both to global climate, ocean acidification and ...
Dynamics of spawning migrations in Northeast Arctic cod
(The University of Bergen, 2010-12-10)
The Northeast Arctic (NA) cod is known to undertake long southbound spawning migrations from their feeding grounds in the Barents Sea, to various spawning grounds along the Norwegian coast. Hence it’s native Norwegian ...
State-dependent spatial and intra-school dynamics in pre-spawning herring (Clupea harengus L.) in a semi-enclosed ecosystem
Distribution and aggregation patterns of pelagic fish in marine ecosystems are hard to predict and understand, particularly since focused studies are typically limited to single field efforts. Our study targets coastal ...
Quantifying recent ecological changes in remote lakes of North America and Greenland using sediment diatom assemblages
(Public Library of Science, 2010-04-02)
Background Although arctic lakes have responded sensitively to 20th-century climate change, it remains uncertain how these ecological transformations compare with alpine and montane-boreal counterparts over the same ...
Gene expression in Atlantic salmon skin in response to infection with the parasitic copepod Lepeophtheirus salmonis, cortisol implant, and their combination
(BioMed Central, 2012-04-05)
Background: The salmon louse is an ectoparasitic copepod that causes major economic losses in the aquaculture industry of Atlantic salmon. This host displays a high level of susceptibility to lice which can be accounted ...
