Elevated deer densities have led to reports of forest regeneration failure and ecological damage. However, there is growing evidence that the biophysical conditions of a forest thatmake it attractive to deermay be a contributing factor in determining browsing levels. Thus, an understanding of settling stimulus—how attractive an area is to deer in terms of food-independent habitat requirements— ...
OBJECTIVE To determine the distribution of lesions and extent of tissues infected with Mycobacterium bovis in a captive population of white-tailed deer. DESIGN Cross-sectional study. ANIMALS 116 captive white-tailed deer. PROCEDURE Deer were euthanatized, and postmortem examinations were performed. Tissues with gross lesions suggestive of tuberculosis were collected for microscopic analys...
BACKGROUND The extant roe deer (Capreolus Gray, 1821) includes two species: the European roe deer (C. capreolus) and the Siberian roe deer (C. pygargus) that are distinguished by morphological and karyotypical differences. The Siberian roe deer occupies a vast area of Asia and is considerably less studied than the European roe deer. Modern systematics of the Siberian roe deer remain controversi...
Since the mid-19th century, multiple introductions of Japanese sika deer (Cervus nippon nippon) and North American wapiti (C. canadensis) have taken place in the British Isles. While wapiti have generally been unsuccessful, sika have been very successful, especially in Scotland where they now overlap at least 40% of the range of native red deer (C. elaphus). Hybridization between these two spec...
One hundred seventy-eight white-tailed deer (Odocoileus virginianus) and 275 mule deer (Odocoileus hemionus) collected from locker plants in the western 2/3 of Nebraska (USA) in November 1997 were examined for the meningeal worm (Parelaphostrongylus tenuis). Parelaphostrongylus tenuis was identified in 17 (10%) of 168 white-tailed deer and in one (<1%) of 273 mule deer. This is the first natura...
Over-abundant populations of white-tailed deer (Odocoileus virginianus) create agricultural and human health and safety issues. The increased economic damage associated with locally overabundant deer populations accentuates the need for efficient techniques to mitigate the losses. Although red lasers can be an efficient tool for reducing damage caused by birds, they are not effective for deer b...
Exurban development (nonmetropolitan, residential development) poses unique challenges for wildlife managers through increases in human-wildlife interactions. However, little is known about hunting activity and human attitudes toward white-tailed deer (Odocoileus virginianus) in exurban areas. In 2004, we surveyed exurbanites near Carbondale, Illinois, regarding their experiences with and attit...
Food plots may increase the value of hunting leases, make deer more visible for viewing opportunities, and improve the diet quality of deer. However, planting food plots is not a replacement for poor habitat management. Maintaining deer densities within the carrying capacity of the habitat, sound livestock grazing management, and maintaining quality habitat should be the first priorities of any...
We estimated chronic wasting disease (CWD) prevalence among vehicle-killed mule deer (Odocoileus hemionus) in select data analysis units (DAUs) in northern Colorado, USA, and compared these with estimated CWD prevalence among mule deer of the same sex sampled in the vicinity of collision sites to assess relative vulnerability of CWD-infected individuals to vehicle collisions. Twenty-five of 171...
Ecologically based management must incorporate components that consider how individuals associate temporally and spatially to environments that provide specific habitat requirements. Recent research has assessed how environments could be classified based on potential to provide deer (Odocoileus virginianus) habitat components. If habitat potential (HP; i.e., capability of habitat types to provi...
