Lead exposure in large carnivores in the greater Yellowstone ecosystem
… I investigated whether large carnivores in the Greater Yellowstone Ecosystem were exposed to lead, and if so, if ammunition ingested from hunter-harvested gut piles was an apparent source of exposure. I tested samples of blood, tissue, and scat for the presence of lead in black bears (Ursus …

BRUCELLOSIS TRANSMISSION BETWEEN WILDLIFE AND LIVESTOCK IN THE GREATER YELLOWSTONE ECOSYSTEM: INFERENCES FROM DNA GENOTYPING
… between wildlife species and cattle in the greater Yellowstone ecosystem has been difficult to assess because the causative agent Brucella abortus bacteria is extremely difficult to isolate for DNA genotyping. We examined transmission of B. abortus between bison, elk, and cattle using nine …

Mountains as Crossroads: Temporal and Spatial Patterns of High Elevation Activity in the Greater Yellowstone Ecosystem, USA
… from the Absaroka and Beartooth Mountains in the Greater Yellowstone Ecosystem (GYE) of the Rocky Mountains, which was a vital crossroads of prehistoric cultures for more than 11,000 years. I include five interlocking analyses. First, I consider the impacts of anthropogenic climate change on high …

Opportunities for coordinated road management on public lands for purposes of ecosystem management: the case of the greater Yellowstone ecosystem
… for coordinated road management for purposes of ecosystem management. The coordination efforts in Greater Yellowstone provide a case study illustrating these opportunities. The study first reviews current literature about ecosystems, ecosystem management goals, benefits and the application of the …

Fluvial processes, beaver activity, and climate in the greater Yellowstone ecosystem and rock type control on hillslope morphology and soil development in the Sandia Mountains, New Mexico
… natural variability in fluvial systems in the Greater Yellowstone Ecosystem. I used beaver-pond and other fluvial deposits as proxy records of beaver occupation to compare historical fluvial activity to that throughout the Holocene. The Holocene record prior to Euro-American activities provides …

Puma Dispersal Ecology in the Central Rocky Mountains
… Central Rocky Mountains including the Northern Greater Yellowstone Ecosystem (NGYE), the Southern Greater Yellowstone Ecosystem (SGYE) and the Garnet Mountains of Montana. We found human-induced mortality reduced inter-population vital rates with population consequences. The NGYE population was …

Sustaining A Conservation Legacy? An In Depth Perspective On the Interagency Bison Management Plan and the Potential for Collaboration
Bison management within Yellowstone National Park (YNP), and the later recognized Greater Yellowstone Ecosystem (GYE), has been a contentious issue since the mid-1900s. At the same time the efforts of Congress and the National Park Service to literally bring the bison back from the brink of …

Stream channel adjustments and persistence of change in response to beaver damming on a fluvial fan, Odell Creek, Montana
Beaver damming in streams is thought to increase bed elevation through in-channel sediment storage, thus beaver reintroductions are used as a river restoration tool to repair incised stream channels. However, effects of beaver damming are dependent on specific stream hydrologic and geomorphic …
