Mule deer (Odocoileus hemionus) populations throughout the west appear to be declining, whereas white- tailed deer (Odocoileus virginianus) populations are increasing. We compared abundance, number of fetuses per female (maternity rate), recruitment, and cause-specific adult ( ♢1 year old) mortality rate for sympatric mule deer and white- tailed deer in south-central British Columbia to assess population growth for each species. White-tailed deer were three times more abundant (908 ± 152) than…

Resource competition and apparent competition in declining mule deer (Odocoileus hemionus)

The apparent competition hypothesis was accepted because high mortality of female cougars and cougar population decline was associated with both white-tailed deer and mule deer population growth.

Cougar Prey Selection in a White-Tailed Deer and Mule Deer Community

It is suspected that cougars are primarily subsisting on abundant white-tailed deer during winter but following these deer to higher elevations as they migrate to their summer ranges, resulting in a greater spatial overlap between cougars and mule deer and disproportionate predation on mule Deer.

A review of the population dynamics of mule deer and black‐tailed deer Odocoileus hemionus in North America

Three models are proposed to explain local population dynamics of Odocoileus hemionus: (i) populations are limited by forage availability and weather; (ii) adult females arelimited by foraging availability, fawns areLimited by forager availability and predation, and population growth is constrained by fecundity and fawn predation; and (iii) large changes in the abundance of predators or alternative prey change predation risk and destabilize population dynamics.

Differences in dietary niche and foraging behavior of sympatric mule and white‐tailed deer

. Mule ( Odocoileus hemionus ) and white-tailed deer ( Odocoileus virginianus ) are congeneric and share similar life histories, yet their distribution is segregated across much of North America.

Effects of predation and forage availability on the survival of black-tailed deer (Odocoileus hemionus columbianus) in the Mendocino National Forest, California

1 Mule deer and black-tailed deer Odocoileus hemionus have exhibited marked population fluctuations throughout their range over the past century. The relative contributions of predation, forage

Prey selection and kill rates of cougars in northeastern Washington

This study introduces an inexpensive, and convenient method to estimate ungulate sightability and relative numbers from ground counts using life-sized animal decoys. Logistic regression (LR) was used

Impacts of recolonizing gray wolves (Canis lupus) on survival and mortality in two sympatric ungulates

Test the hypothesis that the addition of wolves to the existing predator guild would augment predator-induced mortality rates for both ungulates and revealed that wolf-related mortality was low compared with that inflicted by other predators or humans.

Effects of distribution, behavior, and climate on mule deer survival

The results of the study suggest that migrating to potentially higher quality summer foraging areas outweighed the cost of traveling through unfamiliar habitats and energy expenditure associated with migration.

The effect of terrain and female density on survival of neonatal white‐tailed deer and mule deer fawns

The hypothesis that habitat and social characteristics influence coyote (Canis latrans) predation on white‐tailed deer and mule deer fawns in similar ways during the neonatal period is tested and suggests that topographical variation is a critical resource for neonates of many ungulate species, even species like white‐tails deer that use more gentle terrain when older.

Mule Deer, White-Tailed Deer, and Wolves in Jasper National Park, Alberta: 35 Years of Sightings, 1981–2016

Abstract On the basis of annual observations collected over 35 y, we chronicled the trends in abundance of Mule Deer (Odocoileus hemionus) and White-tailed Deer (Odocoileus virginianus) in semi-open



Mortality causes and survival estimates for adult female columbian black-tailed deer

Declines in black-tailed deer (Odocoileus hemionus columbianus) populations and in hunter harvests of deer on Vancouver Island have been contrary to management objectives since the late 1970s.


It is concluded that mule deer and white-tailed deer competitively exclude each other in the San Cayetano Mountains because of the high overlap in spatial distributions, habitat selection, and food habits coupled with the high utilization of the key forage plant.

Deer-predator relationships: a review of recent North American studies with emphasis on mule and black-tailed deer

A review of published studies concerning predator-deer relationships suggests that predation by coyotes, mountain lions, or wolves may be a significant mortality factor in some areas under certain conditions.

Mule deer survival in Colorado, Idaho, and Montana

There are significant year-to-year differences in overwinter survival rates of fawns among states, while annual survival rate of adult females showed less variation across vears, and beta-binomial models of survival distributions were not different between sexes.

Apparent demographic changes in black-tailed deer associated with wolf control on northern Vancouver Island

A simple difference equation model was used to provide a perspective on demographic changes in a Columbian black-tailed deer population prior to and during wolf control on northern Vancouver Island.

Relationships among mule deer fawn mortality, coyotes, and alternate prey species during summer.

C coyote predation can reduce fawn survival in nutritionally healthy deer populations, but alternate prey population levels and cycle phase should be determined by managers prior to decisions about predator control to increase deer populations.


Ten years of data on survival and cause-specific mortality rates of white-tailed deer that are harvested by man and preyed upon extensively by wolves are analyzed to analyze population dynamics of whitetailed deer.

Wolf and bear predation on white-tailed deer fawns in northeastern Minnesota

White-tailed deer fawn mortality was studied during the summers of 1989 and 1990 in northeastern Minnesota, finding that fawns from mothers > 4 years old weighed more and survived better than fawnS from young mothers, which weighed less.


The amount and distribution of deer habitat in Illinois was primarily dependent on intensity of agricultural land use, which was dictated by soil productivity and terrain, and there was no evidence that relative use of available habitat at the county level was adversely affected either by habitat fragmentation or human presence on the landscape.


Pupils of mule deer wintering in the western Great Basin during 1986-1994 existed under similar environmental conditions, but survivorship functions differed among them, and predation by mountain lions was the leading cause of mortality and survivorship.
