Implications of cougar prey selection and demography on population dynamics of elk in northeast Oregon

Creator:

Clark, Darren A.

Abstract:

Mule deer (Odocoileus hemionus hemionus) and Rocky Mountain elk (Cervus canadensis nelsoni; hereafter elk) populations in northeast Oregon have declined in the past 10 to 20 years. Concurrent with these declines, cougar (Puma concolor) populations have apparently increased, leading to speculation that predation by cougars may be responsible for declining...

Ungulate activity classification : calibrating activity monitor GPS collars for Rocky Mountain elk, mule deer, and cattle

Creator:

Gaylord, Adam J.

Abstract:

Ungulate behavior has been studied extensively but direct observation of free-ranging animals over long periods of time and large geographic areas is often prohibitively difficult. Improved technology, such as GPS collars fitted with motion-sensitive activity monitors, provides researchers with a potential tool to remotely collect fine scale activity and location...
