Migratory elk are coming back from Yellowstone National Park with fewer calves due to drought and increased numbers of big predators — two landscape-level changes that are reducing the benefits of migration with broader implications for conservation of migratory animals, according to a new study published in the journal Ecology.
Director and Cofounder WMI
Matt has an undergraduate degree in Biology from the University of Oregon and a Ph.D. in Environmental Studies from the University of California, Santa Cruz. Dr. Kauffman has worked on topics that include the management and recovery of peregrine falcons, evaluating the ecological role of wolves in Yellowstone National Park, and the effects of range management on carnivores in southern Africa. In 2006, Matt joined the Wyoming Cooperative Fish and Wildlife Research Unit and the faculty of the Department of Zoology and Physiology at the University of Wyoming; he is currently the director of the Wyoming Coop Unit. Matt and his graduate students are conducting studies on elk, wolves, moose, deer, pronghorn, 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, including a strong focus on ungulate migration. A primary focus of his research program is to provide timely information to agency biologists charged with managing Wyoming’s wildlife.
Student Cartography Project Manager
Peyton Carl is a student cartographer in the InfoGraphics Lab at the University of Oregon. Since joining the Lab in January of 2022, she’s worked on several projects focused on mapping ungulate migration with the Wyoming Migration Initiative, as well as state agencies including California’s Department of Fish and Wildlife. In early 2023, Peyton took a student project management role in the InfoGraphics Lab to help train students for and manage the USGS mapping effort on ungulate migrations across the Western United States. Peyton enjoys the convergence of her passion for animal conservation and wildlife management with the creativity and design of cartography. Peyton looks forward to pursuing a career where wildlife ecology intersects with GIS and graphic design.
PH.D. Student
Wilde is a Ph.D. student in the Wyoming Coop Unit and the Program in Ecology at the University of Wyoming working with Matt Kauffman. Luke’s doctoral research uses the Sublette mule deer herd’s Red Desert to Hoback migration among others to explore how animals optimally alter migratory behaviors in response to barriers and environmental changes, as well as the mechanism by which juveniles develop their own behavioral profile. Luke also provides data and analysis for social media outreach and heads up development of a curiosity-driven learning curriculum in k-12 classrooms around Wyoming. Before joining WMI, he earned a master’s degree researching the effects of mixed-species social interactions and phenological mismatches on the early-life survival of long-distance migratory shorebirds in Alaska. Luke is an avid climber, fly fisher, and ski mountaineer around Wyoming, Washington, and his home state, Montana.

Postdoctoral researcher
Justine is a postdoctoral researcher who focuses on understanding the origin and maintenance of multiple movement strategies in Wyoming’s pronghorn populations. She is using GPS collar and remote sensing data from across Wyoming to investigate the connection between spatiotemporal environmental variability and the long-distance movement tactics used by pronghorn, which can be migratory, resident, or nomadic. Through her research, Justine hopes to both improve our understanding of long-distance animal movements and inform strategies for the management and conservation of these movements in pronghorn. Justine’s background is in behavioral ecology, and she is broadly interested in understanding the ecological causes of individual behavioral variation and the consequences of this variation at the population- and community-level. Prior to joining WMI, Justine completed her Ph.D. in Ecology and Evolutionary Biology at Princeton University where she studied the movement ecology of antelope in Mozambique’s Gorongosa National Park. Justine received her B.A. in History and B.Sc. in Biological Sciences from the University of Auckland in her home country of New Zealand.
