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)
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. ...
Review of ecosystem models of fjords; new insights of relevance to fisheries management
(The University of Bergen, 2001)
Fjords on the west coast of Norway contain small ecosystems that have similar physical and biological processes as large oceanic ecosystems. Hence, they are ideal experimental facilities. However, ecosystems are complex ...
Antibiotic uptake by cultured Atlantic cod leucocytes and effect on intracellular Francisella noatunensis subsp. noatunensis replication
The granuloma disease caused by Francisella noatunensis subsp. noatunensis in farmed Atlantic cod has not been successfully treated by use of antibacterials, even when antibacterial resistance testing indicates a sufficient ...
Relationships between calibrated ages and depth in stratigraphical sequences: an estimation procedure by mixed-effect regression
We present a procedure for estimating age-depth relationships in stratigraphical sequences by means of a generalized mixed-effect regression using an ancillary function for the partitioning of the fixed effect and the ...
Distribution and autecology of chrysophyte cysts from high Arctic Svalbard lakes: preliminary evidence of recent environmental change
Chrysophycean stomatocyst assemblages were analysed from the sediments of 17 lakes and ponds from Svalbard as one component of a multi-proxy investigation of recent environmental change in the high Arctic. Sediment cores ...
Age and growth determination and stock identification using statolith microstructure of Indian squid, Loligo duvauceli
(The University of Bergen, 2010-05-29)
Age and growth and stock identification of Indian squid, Loligo duvauceli were examined by statolith microstructure and morphological measurements. The Indian squid were sampled from the Gulf of Thailand and the Andaman ...
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 ...
