| serologic evidence of west nile virus infection in birds, tamaulipas state, méxico. | following the introduction of west nile virus (wnv) into north america in 1999, surveillance for wnv in migratory and resident birds was established in tamaulipas state, northern méxico in december 2001. overall, 796 birds representing 70 species and 10 orders were captured and assayed for antibodies to wnv. nine birds had flavivirus-specific antibodies by epitope-blocking enzyme-linked immunosorbent assay; four were confirmed to have antibody to wnv by plaque reduction neutralization test. the ... | 2003 | 14733673 |
| Widespread dispersal of Borrelia burgdorferi-infected ticks collected from songbirds across Canada. | Abstract 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 burgdorferi s.l. Immature blacklegged ticks, Ixodes scapularis, collected from infested songbird ... | 2011 | 21864130 |
| breeding dispersal by birds in a dynamic urban ecosystem. | changes in land cover during urbanization profoundly affect the diversity of bird communities, but the demographic mechanisms affecting diversity are poorly known. we advance such understanding by documenting how urbanization influences breeding dispersal-the annual movement of territorial adults-of six songbird species in the seattle, wa, usa metropolitan area. we color-banded adults and mapped the centers of their annual breeding activities from 2000-2010 to obtain 504 consecutive movements by ... | 2016 | 28030559 |
