Role Of Bird Movements In The Epidemiology Of West Nile And Avian Influenza Virus, Sabir B. Muzaffar, Nichola J. Hill, John Y. Takekawa, William M. Perry, Lacy M. Smith, Walter M. Boyce

Human–Wildlife Interactions

Avian influenza virus (AIV) is influenced by site fidelity and movements of bird hosts. We examined the movement ecology of American crows (Corvus brachyrhynchos) as potential hosts for West Nile virus (WNV) and greater white-fronted geese (Anser albifrons frontalis) as potential hosts for AIVs. Research was based on radio-telemetry studies conducted in the Central Valley of California, USA. While crows were restricted to a small area of only a few square kilometers, the distribution of the geese encompassed the northern Central Valley. The crows used 1.5 to 3.5 different roosting areas monthly from February through October, …

Brucellosis In The Greater Yellowstone Area: Disease Management At The Wildlife–Livestock Interface, Brant A. Schumaker, Dannelle E. Peck, Mandy E. Kauffman

Human–Wildlife Interactions

Elk (Cervus elaphus) and bison (Bison bison) of the Greater Yellowstone area are the last known reservoir of bovine brucellosis (Brucella abortus) in the United States. Domestic cattle occasionally contract the disease while grazing in areas where infected wild ungulates have aborted their fetuses or have given birth. Cases of brucellosis in cattle trigger costly quarantine, testing, and culling procedures. Government agencies and stakeholders, therefore, allocate valuable resources to prevent wildlife-to-cattle transmission. Scientific uncertainty about the biology, epidemiology, and economics of brucellosis makes it difficult to determine the length to which society should go to control it or the combination …
