The effect of fish behaviour and spatial structures on acoustic and trawl surveys
(The University of Bergen, 2007-12-14)
Time series of scientific survey estimates of fisheries resources are used to measure changes in stock size and composition. Standardization of sampling equipment and design is regarded crucial for reliable trawl and ...
Management-driven evolution in a domesticated ecosystem
(Royal Society, 2014-02-12)
Millennia of human land-use have resulted in the widespread occurrence of what have been coined ‘domesticated ecosystems’. The anthropogenic imprints on diversity, composition, structure and functioning of such systems ...
Phylogeography of Phycodrys rubens (Linnaeus) batters from mainland Norway and Svalbard based on nuclear and mtDNA sequences and microsatellites
(The University of Bergen, 2014-04-01)
Phycodrys rubens is a common cold temperate red macroalga in the North Atlantic, a region with a diverse natural history that has shaped the phylogeography for many species. In this study microsatellite loci as well as ...
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 ...
Does size matter? A bioeconomic perspective on optimal harvesting when price is size-dependent
(NRC Research Press, 2011-09-09)
Body size is a key parameter influencing demographic characteristics of fish populations as well as market value of landed catch. Yet in bioeconomic modelling body size is often an overlooked biological and economic ...
Bruk av Biller (Coleoptera) som predatorer på Iberiaskogsneglen, Arion lusitanicus Mabille 1868
(The University of Bergen, 2005-06)
Physiological and molecular mechanisms of oocyte hydration in an evolutionary old teleost, Atlantic herring (Clupea harengus)
(The University of Bergen, 2008-04-11)
This work investigated physiological and molecular mechanisms of oocyte hydration in Atlantic herring (Clupea harengus). Both inorganic and organic solutes were found to be important solutes involved in the hydration ...
Characterization of ‘Candidatus Syngnamydia salmonis’ (Chlamydiales, Simkaniaceae), a bacterium associated with epitheliocystis in Atlantic salmon (Salmo salar L.)
Two Chlamydiales have previously been found to infect Atlantic salmon (Salmo salar L.), Candidatus Piscichlamydia salmonis and Candidatus Clavichlamydia salmonicola. Both develop intracellularly in cyst-like inclusions in ...
Simultaneous Assessment of Soil Microbial Community Structure and Function through Analysis of the Meta-Transcriptome
(Public Library of Science (PLoS), 2008-06-25)
<p>Background: Soil ecosystems harbor the most complex prokaryotic and eukaryotic microbial communities on Earth. Experimental approaches studying these systems usually focus on either the soil community’s taxonomic ...
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 ...
