Prevalence of Borrelia burgdorferi sensu lato and Anaplasma phagocytophilum in questing Ixodes ricinus ticks in relation to the density of wild cervids

Description : 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 ricinus ticks collected in spring for these pathogens from sites with high (Fjellø...

Infestation with Ixodes ricinus ticks on migrating passerine birds in Lithuania and Norway

Description : 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 passerine bird species. During April-May of 2006-2007 and August-September o...

Sex-biased dispersal in a northern ungulate population

Description : In most mammals dispersal is male-biased and in many polygynous ungulates female philopatry and matrilineal grouping involve small-scale genetic structure. We have through sex-related differences in microsatellite allele distribution addressed sex-biased dispersal in a spatially expanding northern u...
