The impact of free-ranging domestic cats on wildlife of the United States.
It is suggested that free-ranging cats cause substantially greater wildlife mortality than previously thought and are likely the single greatest source of anthropogenic mortality for US birds and mammals.
Predicting the global spread of H5N1 avian influenza
H5N1 is more likely to be introduced into the Western Hemisphere through infected poultry and into the mainland United States by subsequent movement of migrating birds from neighboring countries, rather than from eastern Siberia.
Host heterogeneity dominates West Nile virus transmission
It is shown that transmission of West Nile virus (WNV) is dominated by extreme heterogeneity in the host community, resulting in highly inflated reproductive ratios and the importance of determining contact rates between vectors and host species to understand pathogen transmission dynamics.
Tropical winter habitat limits reproductive success on the temperate breeding grounds in a migratory bird
It is shown that the reproductive success of a long‐distance migratory bird is influenced by the quality of habitat located thousands of kilometres away on tropical wintering grounds, which affected key variables associated with reproduction, including the number of young fledged.
West Nile virus emergence and large-scale declines of North American bird populations
The findings demonstrate the potential impacts of an invasive species on a diverse faunal assemblage across broad geographical scales, and underscore the complexity of subsequent community response.
Bird–building collisions in the United States: Estimates of annual mortality and species vulnerability
ABSTRACT Building collisions, and particularly collisions with windows, are a major anthropogenic threat to birds, with rough estimates of between 100 million and 1 billion birds killed annually in
The Neighborhood Nestwatch Program: Participant Outcomes of a Citizen‐Science Ecological Research Project
Formal education is not enough to ensure scientific literacy in a world where ideas and technology are changing rapidly (Hacker & Harris 1992). Projects that invite citizens to be involved in
West Nile Virus Epidemics in North America Are Driven by Shifts in Mosquito Feeding Behavior
It is shown that Culex pipiens, the dominant enzootic and bridge vector of WNV in urbanized areas in the northeast and north-central United States, shifted its feeding preferences from birds to humans by 7-fold during late summer and early fall, coinciding with the dispersal of its preferred host (American robins, Turdus migratorius) and the rise in human WNV infections.
The influence of climate on the timing and rate of spring bird migration
The results suggest that, although the onset of migration may be determined endogenously, the timing of migration is flexible and can be adjusted in response to variation in weather and/or phenology along migration routes.
