Arthur works on the ecology of wildlife migration and the interactions of large carnivores and their prey. He also studies the influences of human disturbance in these systems. Most of his current research is in the northern Rockies and the southern Andes. In Wyoming, he is studying the effects of wolves, bears, and drought on elk populations, and initiating new research on the major elk migrations of the Greater Yellowstone Ecosystem. In Argentina, he is studying the influence of pumas on native camelids and the surrounding landscape at San Guillermo National Park. Arthur often works collaboratively with wildlife agencies to design research projects that address specific management and conservation issues.
