Current Sponsored Projects
- Timber harvest and the Selkirk Elk: How does forest structure influence predator-prey interactions?
Our proposed research builds off the Washington Predator-Prey Project, a multi-year study mandated by the Washington state legislature to investigate the impact of wolves on ungulates by tracking the movement and survivorship elk, white-tailed deer, and mule deer. We propose to build on this work by conducting vegetation surveys to determine how human modifications of the landscape (i.e., timber harvest, the predominant forest disturbance in the area) influence elk by dually altering forage availability and by influencing predation risk via changes in the habitat structure, with implications for elk management across the West.
- Animals on the Move: Remotely Based Determination of Key Drivers Influencing Movements and Habitat Selection of Highly Mobile Fauna Throughout the ABoVE Study Domain
Facilitated by many data-sharing collaborations with US and Canadian government agencies, we will use space-based wildlife tracking technology to build an integrated dataset of regional-scale and near-continuous descriptions of passerine (American robins), raptor (Golden Eagles, ungulate (caribou, moose) and predator (wolf and brown bear) locations with both static and dynamic remote sensing products and other regional-scale geospatial datasets.
- Assessing Alpine Ecosystem Productivity to Environmental Change using Dall Sheep as an Iconic Indicator Species
We will: (a) produce times series of snow extent, NDVL, and shrub encroachment though alpine areas of the ABoVE domain, (2) evaluate how these factors affect Dall sheep movement, habitat selection, and population viability, (3) improve a spatially-explicit snowpack evolution model, and (4) relate our improved understanding of alpine ecosystem dynamics to the societal implication of altered sheep harvest.
- CAREER: Integrating Positive and Negative Interactions in Carnivore Community Ecology
The goal of this study is to understand how large carnivores affect smaller carnivores through negative interactions (predation, competition) as well as positive interactions (providing food via ungulate carcasses).
- Impacts of Tour Boat Shore Excursions on Terrestrial Wildlife Glacier Bay National Park
This project will use non-invasive methods to quantify species occupancy and activity levels to compare between sites used for shore excursions versus those that are not and between days when human use occurs versus days in which no human use occurs at the same site.
- Population Dynamics of Forest Carnivores in Denali
The objective of this agreement is to support research that will increase our understanding of factors affecting the distribution and abundance of carnivores in Denali National Park and Preserve. The project will use methods developed previously by the Principal Investigator to track the distribution, abundance, and habitat partitioning among forest carnivores in Denali.
