Population connectivity: dam migration mitigations and contemporary site fidelity in arctic char
(Journal article; Peer reviewed, 2011-07-14)BACKGROUND: Animal feeding and spawning migrations may be limited by physical barriers and behavioral interactions. Dam constructions (e.g. hydropower) commonly include gateways for fish migrations to sustain ecological ... -
Infestation with Ixodes ricinus ticks on migrating passerine birds in Lithuania and Norway
(Journal article; Peer reviewed, 2009)Ticks are known to carry several pathogenic agents of human diseases. To define the role of migrating birds as host and disseminators of ticks in Lithuania and Norway we analysed immature stage of ticks feeding on different ... -
Genetic variation and structure in Norwegian red deer
(Doctoral thesis; Peer reviewed, 2008-07)In all species the abundance and distribution of populations vary through time and space, but recently major changes in the size and range of many populations have been observed. Population contractions and founder events ... -
Comparison of Norwegian poultry, waterborne and clinical isolates of Campylobacter jejuni by ribotyping
(Journal article; Peer reviewed, 2009)Campylobacteriosis is the most frequently occurring food and waterborne gastroenteritis in Norway and 90% of cases are caused by Campylobacter jejuni. Campylobacteriosis is epidemiologically associated with use of ... -
Infestation of mice and voles with Ixodes ricinus ticks in Lithuania and Norway
(Journal article; Peer reviewed, 2009)A total of 693 small rodents were live-trapped in Lithuania and Norway. In Lithuania, the mice Apodemus flavicollis and A. agrarius were more frequently infested with ticks than the voles Microtus arvalis and Myodes ... -
Prevalence of Borrelia burgdorferi sensu lato and Anaplasma phagocytophilum in questing Ixodes ricinus ticks in relation to the density of wild cervids
(Journal article; Peer reviewed, 2009-11-27)BACKGROUND: Borrelia burgdorferi sensu lato and Anaplasma phagocytophilum have been considered as pathogens in animals and humans. The role of wild cervids in the epidemiology is not clear. We analyzed questing Ixodes ... -

Genetic structure in an expanding cervid population after population reduction
(Journal article; Peer reviewed, 2009)The Norwegian red deer population (Cervus elaphus) was from the mid eighteenth to the early twentieth century drastically reduced in size and distribution but has the last century expanded both demographically and spatially. ... -
Diversity of thermophilic Campylobacter isolated from the Bø River, Southeast Norway
(Journal article; Peer reviewed, 2009)Out of 125 samples we isolated 45 thermophilic Campylobacter spp. from Bø River by filtration followed by growth on selective agar plates. The species were identified by biotyping, multiplex PCR and riboprinting. C. jejuni ... -
Superoxide dismutase polymorphisms in wild populations of herb Paris (Paris quadrifolia L., Trilliaceae)
(Journal article, 2003)Polymorphism of superoxide dismutase (SOD) was investigated in leaves of herb Paris (Paris quadrifolia L., Trilliaceae). The plants were collected during the summer and autumn of 2001 from different natural locations in ... -

Genetic variation of ticks (Ixodes ricinus L.) in the Lithuanian and Norwegian populations
(Journal article; Peer reviewed, 2006)RAPD markers were used to measure the genetic diversity of 119 individuals of Ixodes ricinus collected from Lithuania and Norway. The samples were analysed within and also between the populations. We analysed 74 loci in ... -
Diversity in prevalence and genospecies of Borrelia burgdorferi sensu lato in Ixodes ricinus ticks and rodents in Lithuania and Norway
(Journal article; Peer reviewed, 2008)A total of 1679 questing Ixodes ricinus ticks collected in Lithuania and 535 I. ricinus ticks collected in Norway from locations with different habitats were investigated for the presence of Borrelia burgdorferi sensu lato. ... -
Prevalence of Anaplasma phagocytophilum and Babesia divergens in Ixodes ricinus ticks from Lithuania and Norway
(Journal article; Peer reviewed, 2008)We detected Anaplasma phagocytophilum and Babesia divergens in Ixodes ricinus ticks collected from different locations in Lithuania and Norway by using the Taq Man based real-time PCR method. The msp2 gene of A. phagocytophilum ... -

Haematological and serum biochemical reference values in free-ranging red deer (Cervus elaphus atlanticus)
(Journal article; Peer reviewed, 2004)Analyses of haematological and biochemical constituents were carried out on the Norwegian subspecies of free-ranging red deer (Cervus elaphus atlanticus). All animals were captured from January to March by using a mixture ... -
Malnutrition in farmed red deer hinds (Cervus elaphus atlanticus) in Norway
(Research report, 2005)Malnutrition was studied in farmed red deer. Malnourished animals did not recover from winter energy loss, remained in poor condition throughout the summer, and some died of starvation. Liver analysis of one hind that died ...
