No influence of oxygen levels on pathogenesis and virus shedding in Salmonid alphavirus (SAV)-challenged Atlantic salmon (Salmo salar L.)
(BioMed Central, 2010-08-21)
Background For more than three decades, diseases caused by salmonid alphaviruses (SAV) have become a major problem of increasing economic importance in the European fish-farming industry. However, experimental infection ...
Mortality, Recruitment and Change of Desert Tree Populations in a Hyper-Arid Environment
Background: Long-term vegetation changes in hyper-arid areas have long been neglected. Mortality, recruitment and change in populations of the ecologically and culturally important and drought persistent Acacia tortilis ...

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 ...
Predation by carabid beetles (Coleoptera, Carabidae) on the invasive Iberian slug Arion lusitanicus
(The University of Bergen, 2010-06-21)
Predator-prey and host-parasite interactions are essential in understanding the population dynamics of any species, including pest species. In fact, integrated pest management that incorporates biological control requires ...

The impact of lysine and arginine ratios in plant-based protein diets on appetite, growth performance and gene expression of brain neuropeptide Y (NPY) and cholecystokinin (CCK) in juvenile cobia (Rachycentron canadum)
(The University of Bergen, 2013-01-31)
Aquaculture of cobia, Rachycentron canadum is hampered by lack of good feeding protocols and nutritionally optimized diets. Studies on the role of appetite and feeding behavior regulating neuropeptides in cobia have not ...
