Evolution of temperature optimum in Thermotogaceae and the prediction of trait values of uncultured organisms
(Springer Link, 2011-06-03)
Quantitative characterization of the mode and rate of phenotypic evolution is rarely applied to prokaryotes. Here, we present an analysis of temperature optimum (Topt) evolution in the thermophilic family Thermotogaceae, which ...
Separating blue whiting (Micromesistius poutassou Risso, 1826) from myctophid targets using multi-frequency methods
(The University of Bergen, 2008)
Blue whiting (Micromesistius poutassou Risso, 1826) is a physoclists species, widely distributed in the Barents Sea, Norwegian Sea and Mediterranean Sea. They appear on the continental slope and shelf, in high concentration ...
Ichthyobodo infections on farmed and wild fish. Methods for detection and identification of Ichthyobodo spp.
(The University of Bergen, 2013-03-01)
<p>Ichthyobodosis is an important parasitic disease that has caused severe loss among ornamental and farmed fish world wide for more than a century. The disease is caused by heavy infections on skin and gills by parasitic ...
Competition between marine osmotrophs for phosphorus and nitrogen : implications for the microplanktonic food web
(The University of Bergen, 2007-03-29)
Understanding how competition for nutrients structures the flows of C, N, P, and other elements through the microbial food web may seem central to our understanding of the role and function of this part of aquatic ...
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 ...
Relationships between spawning ground identity, Latitude and early life thermal exposure in Northeast Arctic Cod
(Journal of Northwest Atlantic Fishery Science, 2008)
from its feeding grounds in the Barents Sea to various spawning banks along the Norwegian coast. Prior to the 1990s these banks were located on a wide latitudinal range from Finnmark (~71º N) to Møre (~63º N), or even ...
Biology and distribution patterns of some deepwater demersal fishes in the North Atlantic, with special reference to Antimora rostrata A study related to the project “Patterns and Processes of the ecosystems of the northern Mid-Atlantic”, MAR-ECO, 2001-2008
(The University of Bergen, 2007-06-19)
The study seeks to increase our knowledge on deepwater demersal fish assemblages and the biological adaptations of Antimora rostrata. This widespread deep-living demersal teleost is essentially used as an example species. ...
Pigghuder på korallrev i norske farvann
(The University of Bergen, 2001)
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 ...
