Effects of risk assessment, predator behavior, and habitat on escape behavior in Columbian black-tailed deer
The relationship between preflight risk assessment by prey and the escape behaviors they perform while fleeing from predators is relatively unexplored. To examine this relationship, a human observer approached groups of Columbian black-tailed deer (Odocoileus hemionus columbianus), varying his behavior to simulate more or less threatening behavior. We measured the focal deer’s angle of escape, ...
متن کاملLate Prehistoric and Early Historic Abundance of Columbian White-Tailed Deer, Portland Basin, Washington and Oregon, USA
Two species of deer, each with 2 subspecies, are currently found in the Pacific Northwest, USA, of the contiguous lower 48 states (Smith 1991, Demarais et al. 2000, Kie and Czech 2000). In general, mule deer (Odocoileus hemionus hemionus) are found east of the crest of the Cascade Mountains of Washington and Oregon, whereas Columbian black-tailed deer (O. h. columbianus) are found to the west o...
متن کاملParelaphostrongylus odocoilei in Columbian black-tailed deer from Oregon.
Documenting the occurrence of Parelaphostrongylus odocoilei has historically relied on the morphological examination of adult worms collected from the skeletal muscle of definitive hosts, including deer. Recent advances in the knowledge of protostrongylid genetic sequences now permit larvae to be identified. Dorsal-spined larvae (DSLs) collected in 2003-2004 from the lung and feces of six Colum...
متن کاملUse of predator hair to enhance perceived risk to white-tailed deer in a foraging context
Deer react to predator scent in varying degrees even when exposed to unknown predators. This response could be genetically based and maintained as long as the population is exposed to predation. We tested whether predator scent in the form of hair would enhance perceived risk and serve as a foraging repellent to free-ranging white-tailed deer (Odocoileus virginianus). During the winters of 2013...
متن کامل03 Rooney (jr/d)
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...
