Movement and mortality of translocated urban-suburban grey squirrels
During summer and autumn of 1994-1997, we determined the movements and mortality of 38 adult male Eastern grey squirrels (Sciurus carolinensis) that had been captured in urban-suburban backyards and translocated to a large forest. The squirrels did not fare well. Squirrels not found dead or classified as ‘probable mortality’ disappeared from the forest with a […]
Birdsongs keep pace with city life: changes in song over time in an urban songbird affects communication
Animals in urban environments often must adjust their vocalizations to be heard over the din of anthropogenic ambient noise. Most studies of this process use current comparisons of environments that vary in ambient noise; here, we evaluate over time the effects of the urban environment on signal structure and salience. We show that white-crowned sparrow, […]
Urban wildlife research: Past, present, and future
Despite expanding urban areas and increased awareness of urbanization impacts on wildlife, trends in urbanwildlife studies have not been evaluated systematically. We performed a thorough assessment of such research, evaluating urbanwildlife publications from 16 leading journals in animal behavior, conservation, ecology, general science, landscape ecology, and wildlife biology from 1971 to 2010. Using a systematic […]
