Bill Hamilton, John T. Perry Jr. Professor of Research Science at Washington and Lee University, and Chris Geremia, a researcher with the National Park Service at Yellowstone, served as co-first authors, with co-author Jerod Merkle, associate professor and Knobloch Professor of Migration Ecology and Conservation at the University of Wyoming. While momentum is building to restore bison across North America, most efforts focus on small, managed herds, leaving it unclear how large, migrating herds shape landscapes and whether their effects enhance or degrade ecosystems.
