Demographic influences on cougar residential use and interactions with people in western Washington

Autor: Brian N. Kertson, Rocky D. Spencer, Christian E. Grue

Publikováno v: Journal of Mammalogy. 94:269-281

Sound management of large carnivore populations in wildland–urban environments requires accurate information regarding the ecology of these populations and factors contributing to their interactions with people. We quantified cougar (Puma concolor)

Autor: Brian N. Kertson, Christian E. Grue, Rocky D. Spencer

Publikováno v: Northwestern Naturalist. 92:175-185

The Cougar (Puma concolor) is an apex predator whose occurrence and space- use patterns are closely tied to the abundance and vulnerability of ungulate prey. Deer (Odocoileus spp.) and Elk (Cervus elaphus) readily use residential portions of the land

Cougar space use and movements in the wildland–urban landscape of western Washington

Autor: Brian N. Kertson, Jeffrey Hepinstall-Cymerman, John M. Marzluff, Rocky D. Spencer, Christian E. Grue

Publikováno v: Ecological Applications. 21:2866-2881

The wildland–urban interface lies at the confluence of human-dominated and wild landscapes, creating a number of management and conservation challenges. Because wildlife ecology, behavior, and evolution at this interface are shaped by both natural

Revisions of Rump Fat and Body Scoring Indices for Deer, Elk, and Moose

Autor: John G. Cook, Shannon L. Murphie, Larry L. Irwin, David J. Vales, P. Briggs Hall, Patrick J. Miller, Scott M. McCorquodale, Rocky D. Spencer, Rachel C. Cook, Kathryn A. Schoenecker, Thomas R. Stephenson, Woodrow L. Myers

Publikováno v: Journal of Wildlife Management. 74:880-896

Because they do not require sacrificing animals, body condition scores (BCS), thickness of rump fat (MAXFAT), and other similar predictors of body fat have advanced estimating nutritional condition of ungulates and their use has proliferated in North

POPULATION ESTIMATION AND BIASES IN PAINTBALL, MARK–RESIGHT SURVEYS OF ELK

Autor: Joshua J. Millspaugh, John R. Skalski, Rocky D. Spencer

Publikováno v: Journal of Wildlife Management. 69:1043-1052

To overcome costs and logistical constraints associated with capturing and marking a sufficient number of elk (Cervus elaphus) for population estimation, elk are sometimes marked with paintballs fired from a helicopter flying overhead. Although marki

Autor: Bryan L. Murphie, Kelly R. McALLISTER, Rocky D. Spencer, Louis C. Bender, Greg A. Schirato

Publikováno v: Journal of Wildlife Management. 68:870-878

We determined survival rates, causes of mortality, and documented impacts of harvest on ≥1.5-year-old male (hereafter, male) Columbian black-tailed deer (Odocoileus hemionus columbianus) in 2 Washington, USA, game management units (GMUs; Skookumchu
