Mycobacterium bovis (M. bovis), the causative agent of bovine tuberculosis, has been identified in nine geographically distinct wildlife populations in North America and Hawaii and is endemic in at least three populations, including members of the Bovidae, Cervidae, and Suidae families. The emergence of M. bovis in North American wildlife poses a serious and growing risk for livestock and human...
Fifty Nerodia sipedon living along two kilometers of an urban stream in northeastern Pennsylvania were radiotracked over three activity seasons, yielding more than 2520 relocations. Half the stream length is urbanized, flowing through a city park at the head of the study area and an industrial area at the downstream end; the half between is relatively natural, flowing through a conservation cor...
Survival and development of wildlife sustains the balance and stability of the entire ecosystem. Wildlife monitoring can provide lots of information such as wildlife species, quantity, habits, quality of life and habitat conditions, to help researchers grasp the status and dynamics of wildlife resources, and to provide basis for the effective protection, sustainable use, and scientific manageme...
Projecting risks posed to aviation safety by wildlife populations is often overlooked in airport land-use planning. However, the growing dependency on civil aviation for global commerce can require increases in capacity at airports which affect land use, wildlife populations, and perspectives on aviation safety. Our objectives were to (1) review legislation that affects airports and surrounding...
Both the percent of producers reporting and the value of wildlife-caused losses increased from 1989 to 1994. In 1994, 58% of respondents reported wildlife-caused losses of their agricultural commodities, an increase from the 55% of respondents who reported losses in 1989. Based on the median value of producer-estimated loss, wildlifecaused losses cost producers approximately $591 million in 199...
Numerous emerging infectious diseases (EIDs) have arisen from or been identified in wildlife, with health implications for both humans and wildlife. In the practice of wildlife conservation, to date most attention has focused on the threat EIDs pose to biodiversity and wildlife population viability. In the popular media and public eye, however, wildlife is often only portrayed as the cause of E...

Habituation of wildlife is a double edged sword. It has been enormously useful in studying and filming free-living animals in their natural environment and providing a recreational opportunity. However, it is also a source of mortal danger to its practitioners, to habituated animals, as well as to hapless third parties. Attraction or positive habituation, in which wildlife seeks out the presenc...
Wildlife–aircraft collisions (wildlife strikes) with civilian and military aircraft pose notable risks and economic losses. The 4 military services within the U.S. Department of Defense maintain records regarding wildlife strikes with military aircraft. Although rotary-wing aircraft operations comprise important mission components within all 4 military services, no assessment of wildlife strike...
