In order to have a good perspective of wild animals, it is necessary to determine their population and genetic structure. It provides an opportunity to decide on better conservation managements. In the wilderness, due to the escapable nature and sometimes not having the distinguishable bisexual appearance, sex identification could be difficult by observing animals. The X- and Y- chromosome link...
A territorial isolation is a danger to the game population, causing deterioration called the inbreeding depression. The typical signs are anomalous body proportions, such as short lower jaw, shortened lifetime, weak physique and lower birth rate. This is caused by low number of game in the community. White colored deer is in the location of the CzechRepublicbred in separation since 18th century...
the aim of the study was to assess regional differences in selenium content in the environment based on analysis of the se concentrations in liver and kidney of red deer from central, northern, south-eastern and south-western poland. the level of selenium in organs was determined using spectrofluorometric methods. the mean concentration of selenium in the liver and kidney of red deer was 0.084 ...
Deer impacts on woodlands and forests are not confined to Europe. Significant deer impacts on forests have been recorded in New Zealand (Stewart and Burrows, 1989), Japan (Shimoda et al., 1994), and the United States (Alverson et al., 1988; Stromayer and Warren, 1997; Waller and Alverson, 1997). This paper focuses on deer impacts in North America, and draws on my own research over the past 5 ye...
Wildlife reservoirs ofMycobacterium bovis represent serious obstacles to the eradication of tuberculosis in domestic livestock. In Michigan, SA tuberculous white-tailed deer transmit M. bovis to cattle. One approach in dealing with this wildlife reservoir is to vaccinate deer in order o interrupt the cycle of deer to deer and deer to cattle transmission. Thirty-one white-tailed deer were assign...

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...
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.
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...
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...
