The emotion system promotes diversity and evolvability
(Royal Society Publishing, 2014-08-06)
Studies on the relationship between the optimal phenotype and its environment have had limited focus on genotype-to-phenotype pathways and their evolutionary consequences. Here, we study how multi-layered trait architecture ...
Bacterial growth control in marine environments : from experimental approaches to comparative analyses
(The University of Bergen, 2010-12-14)
To understand (1) the role of heterotrophic bacteria in the biogeochemical cycles, (2) the fate of the organic carbon and mineral nutrients, and (3) the flow of energy to higher trophic levels, we need to understand how ...
Human-induced evolution caught in action: SNP-array reveals rapid amphi-atlantic spread of pesticide resistance in the salmon ecotoparasite Lepeophtheirus salmonis
(BioMed Central, 2014-10-26)
<p>Background: The salmon louse, Lepeophtheirus salmonis, is an ectoparasite of salmonids that causes huge economic losses in salmon farming, and has also been causatively linked with declines of wild salmonid populations. ...
Foraging ecology and learning. Adaptive behavioural strategies and the value of information
(The University of Bergen, 2006-12-12)
All animals face the challenge of acquiring resources for growth, survival, and reproduction. In environments that vary in time and space, foragers need to make apparently complex foraging decisions on which prey to ...
Rapid and reliable cloning of PCR products
(Cold Spring Harbor Laboratory Press, 1991-08-08)
The systematics of Cephalaspidea (Mollusca: gastropods) revisited, with a study on the diversity of deep sea Philinidae sensu lato from the West Pacific
(The University of Bergen, 2013-11-26)
The Cephalaspidea are the second most diverse marine clade of the Euthyneura gastropods, after the Nudipleura with many groups still known largely from shells or little anatomical data. These marine snails occur worldwide ...
Biodiversity studies in Afrotropical moth flies (Diptera: Psychodidae)
(The University of Bergen, 2011-09-01)
NB! The nomenclatural acts proposed herein are not validly published according to the International Code of Zoological Nomenclature and must therefore be considered mere suggestions rather than valid scientific names(ICZN, ...
Investigation of crustaceans from shelf areas in the Gulf of Guinea, with special emphasis on Brachyura
(The University of Bergen, 2009)
Crustacean abundance on continental shelves off Nigeria, Cameroon and Gabon in the Gulf of Guinea was investigated in this study. Quantitative data was sampled with a 0.1 m² Van Veen grab during a survey with RV Dr. Fridtjof ...
Morphological and functional modifications of the gastrointestinal tract during metamorphosis in Atlantic halibut (Hippoglossus hippoglossus)
(The University of Bergen, 2014-04-23)
<p>Metamorphosis in flatfish is the transition from a symmetrical larva to an asymmetrical juvenile stage, allowing the organism to utilize new resources in a different habitat and thus providing an evolutionary advantage. ...
Unaccounted mortality in purse seine fisheries. Quantification and mitigation of slipping mortality
(The University of Bergen, 2014-06-06)
<p>Purse seining is an efficient fishing method that is used to catch most of the world’s pelagic fish species. In some of these fisheries slipping is used to adjust catch size, increase catch value or to release illegal ...
