Research Interests
Matt and his graduate students are conducting studies on elk, wolves, moose, deer, and bighorn sheep in Wyoming, addressing the influence of habitat condition, predation, human disturbance, and energy development on these species. Matt’s research combines work on animal physiology, behavior and demography to better understand population- and landscape-level processes. A primary focus of this work is to provide timely information to agency biologists charged with managing Wyoming’s wildlife.
Teaching Interests
Matt teaches graduate courses in quantitative analysis of spatial wildlife data, community ecology of wildlife, and migration ecology.

World's Longest Mule Deer Migration: Red Desert to Hoback
In 2016, researchers in Wyoming discovered the world's longest migration of mule deer. A doe fitted with a GPS tracking collar migrated 242 miles one way. She is known as Deer 255. Each summer, she lives in the heart of the Greater Yellowstone Ecosystem, but travels far into Wyoming's sagebrush sea and high desert ecosystem for winter.

View this webinar for more information about the effects of climate change on moose, mule deer, and elk in Wyoming.Linking Mule Deer Migration to Spring Green-Up in Wyoming
Each year, plants and animals undergo certain life cycle events, such as breeding or flowering. These phenological events are linked to weather and climate, and as temperature and precipitation patterns have changed, some spring events are occurring earlier. These changes in plant phenology can have cascading effects on wildlife such as elk, moose, and mule deer, which depend on plants for food. I - Data
Age ratios and landscape change covariates for mule deer (Odocoileus hemionus) herd units in Wyoming, USA, 1985-2019
Sagebrush ecosystems and wildlife that depend on them are under pressure from development, changing climate, as well as natural and human-caused disturbance. Mule deer (Odocoileus hemionus) are of particular concern due to population declines across many western states. We initiated a study to evaluate landscape-level changes ( disturbances, habitat treatments, development, and climate change) inSeasonal movements of mule deer and pronghorn in Wyoming, 2014-2021

For ungulates and other long-lived species, life-history theory predicts that nutritional reserves are allocated to reproduction in a state-dependent manner because survival is highly conserved. Further, as per capita food abundance and nutritional reserves decline (i.e., density dependence intensifies), reproduction and recruitment become increasingly sensitive to weather.

According to risk-sensitive foraging theory, animals should make foraging decisions that balance nutritional costs and gains to promote fitness.
