Density‐dependent habitat selection in plains bison

open access: yesThe Journal of Wildlife Management, EarlyView.
Using GPS collar data, we tested whether habitat selection of plains bison in Grasslands National Park, Canada, was density dependent. Bison selected for areas of high vegetation productivity far from human activity when population density was low and increased use of lower productivity habitat closer to disturbance as density increased.

Feral horses influence both spatial and temporal patterns of water use by native ungulates in a semi‐arid environment

open access: yesEcosphere, 2018
The horse (Equus caballus) is a feral ungulate that currently exceeds target population sizes in many areas of western North America. Horses are behaviorally dominant over native ungulates and outcompete the latter for access to water sources. However, a

Habitat use and spatio‐temporal interactions of mule and white‐tailed deer in an area of sympatry in NE Washington

open access: yesEcosphere, 2021
Sympatric species that are ecologically similar must either segregate through habitat disassociation or engage in biotic interactions with one another. Mule (Odocoileus hemionus) and white‐tailed deer (Odocoileus virginianus) are similar ungulate species

Prey Behavior, Age-Dependent Vulnerability, and Predation Rates [PDF]

open access: yes, 2008
Variation in the temporal pattern of vulnerability can provide important insights into predator-prey relationships and the evolution of antipredator behavior. We illustrate these points with a system that has coyotes (Canis latrans) as a predator and two

Understanding contingency in wolf‐mediated livestock predation across a mosaic of land uses: An agent‐based modelling approach

open access: yesPeople and Nature, EarlyView.
Abstract The return of grey wolves to multi‐use landscapes in North America and Europe raises concerns over accompanying risks of livestock predation. While local‐level risk factors have received attention, it is difficult to explore the role that landscape‐scale variables, such as landscape connectivity, play in driving livestock losses.

Identifying migration corridors of mule deer threatened by highway development

open access: yesWildlife Society Bulletin, 2015
Highways are hazardous to migratory ungulates world‐wide, causing direct and indirect impacts to ungulate survival. Moreover, significant financial costs are incurred in damage from wildlife–vehicle collisions and in building and maintaining wildlife ...

Risky business: relating probability of direct contact to risk of chronic wasting disease

open access: yesFrontiers in Ecology and Evolution, 2023
Chronic wasting disease (CWD) is a fatal, prion disease of cervids that was first detected in Alberta in 2005. Transmission of CWD by direct contact with infected individuals plays a major role in the early phases of an outbreak.
