From bighorn sheep in the Sierras of California to pronghorn in central Wyoming, we study what makes ungulates and their populations tick.

Each one of our projects is a little different, but we tend to have common themes throughout most of our projects: nutritional ecology, an individual focus, and long-term data. By studying nutritional ecology, we can learn how habitat and other environmental factors influence individuals, and then understand how individuals come together to make up a whole population. By looking at individuals and populations over many years, we start to get a a better sense of what is driving populations.

Check out some of our projects below to see what we've been up to!

A bighorn sheep ewe is laying down in short alpine plants. She has closed her eyes just slightly and is leaning against a lamb. The lamb is facing away from the camera, with a hesitant look on its face.

Recreation in Sheep Country (RISC) Project

A mule deer in her summer coat walks up a hill covered in red soil. There are a few juniper trees and patches of short shrubs, but otherwise the landscape is mostly soil. She is wearing a GPS collar, and appears to be glancing at the camera out of the side of her eye.

A large female moose stands in the open sagebrush, looking directly at the camera. Her coat is thick and healthy, and the sky behind her is a clear blue.
