Infection Prevalence of Borrelia burgdorferi in Ticks Collected from Songbirds in Far-Western Canada
Worldwide, wild birds play a vital role in the dispersal of ticks that harbour tick-borne pathogens, including Borrelia burgdorferi, the Lyme disease bacterium. Using PCR testing, we found 124 (31%) of 405 ticks (4 species), which were collected from 21 species of birds in far-western Canada, to be infected with B. burgdorferi. Transstadial transmission of B. burgdorferi occurred from larva to ...
متن کاملMarine Ecology: Reaping the Benefits of Local Dispersal
A central question of marine ecology is, how far do larvae disperse? Evidence is accumulating that the probability of dispersal declines rapidly with distance. This provides an incentive for communities to manage their own fish stocks and cooperate with neighbors.
متن کاملFirst record of Amblyomma rotundatum tick (Acari: Ixodidae) parasitizing a bird collected in Canada
Migratory birds disperse engorged ticks across Canada during northward spring migration. During our tick-host study, we collected a nymphal Amblyomma rotundatum Koch, from a Veery, Catharus fuscescens (Stephens) (Passeriformes: Turdidae), at Long Point, Ontario, Canada. In the laboratory, this nymph molted to a female in 44 d. The infestation of A. rotundatum on a Veery constitutes a first tick...
متن کاملWidespread dispersal of Borrelia burgdorferi-infected ticks collected from songbirds across Canada.
Millions of Lyme disease vector ticks are dispersed annually by songbirds across Canada, but often overlooked as the source of infection. For clarity on vector distribution, we sampled 481 ticks (12 species and 3 undetermined ticks) from 211 songbirds (42 species/subspecies) nationwide. Using PCR, 52 (29.5%) of 176 Ixodes ticks tested were positive for the Lyme disease spirochete, Borrelia burg...
متن کاملBirds see the trees inside the forest: The potential impacts of changes in forest composition on songbirds during spring migration
Since European settlement, hardwood dominated forests of the Upper American Midwest have undergone compositional changes due to fire suppression and changes in land use. It is not clear how these changes affect songbirds during spring migration. In 2009 and 2010, we quantified foraging behavior by migratory songbirds during spring migration and collected data on tree and sapling diversity in th...
