Wildlife reservoirs of Mycobacterium bovis represent serious obstacles to the eradication of tuberculosis in domestic livestock. In Michigan, USA tuberculous white-tailed deer transmit M. bovis to cattle. One approach in dealing with this wildlife reservoir is to vaccinate deer in order to interrupt the cycle of deer to deer and deer to cattle transmission. Thirty-one white-tailed deer were ass...
Herbivores can profoundly influence plant species assembly, including plant invasion, and resulting community composition. Population increases of native herbivores, e.g. white-tailed deer (Odocoileus virginianus), combined with burgeoning plant invasions raise concerns for native plant diversity and forest regeneration. While individual researchers typically test for the impact of deer on plan...
due to the fact that a considerable part of europe, including some regions of poland, isconsidered to be deficient in selenium, it seems necessary to develop a selenium map for different regions of poland, which will be used in future to prepare a prophylaxis programme against selenium deficiency inanimals. the aim of the study was to determine selenium content in selected organs (liver and kid...
OBJECTIVE To determine whether Mycobacterium bovis can be transmitted from experimentally infected deer to uninfected in-contact deer. ANIMALS Twenty-three 6-month-old white-tailed deer. PROCEDURE On day 0, M bovis (2 X 10(8) colony-forming units) was administered by intratonsillar instillation to 8 deer; 3 control deer received saline (0.9% NaCl) solution. Eight in-contact deer were coming...
Since January 2007, a total of 11 rabid deer from 4 deer farms have been identified in 2 neighboring Pennsylvania counties. Vaccination of deer against rabies, decreasing wildlife animal contact with deer, and education of deer farmers may prevent further cases of rabies in captive deer and exposures to humans.
A leadership team developed an adaptive management program to reduce deer density and impact on a 29,642-ha forested demonstration area in northwest Pennsylvania incorporating goal setting, monitoring, and communicating with and motivating hunters. We linked reduction of deer density to environmentally sustainable levels with an appeal to the values of hunters (improving deer and habitat qualit...
I examined the interactions of key components of a hunting system of Sitka black-tailed deer (Odocoileus hemionus sitkensis) on Prince of Wales Island, Alaska to address concerns of subsistence hunters and to provide a new tool to more effectively monitor deer populations. To address hunter concerns, I documented local knowledge and perceptions of changes in harvest opportunities of deer over t...
