Arthur is an ecologist who currently works on large mammal migrations and the effects of large carnivores on their prey. He also studies the effects of human disturbance in these systems, and has a strong interest in understanding the causes of conflict between people and wildlife. Most of Arthur's 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 (GYE). In Argentina, he is studying the influence of puma predation on vicuñas, condors, and the surrounding landscape of the San Guillermo Biosphere Reserve.
Arthur often works with wildlife and land management agencies to design projects that address specific conservation challenges. Along with wildlife photojournalist Joe Riis, Arthur was awarded the 2013 Camp Monaco Prize for efforts to advance biodiversity conservation in the GYE through linked scientific research and public outreach on the subject of trans-boundary wildlife migrations.
Arthur completed his Ph.D. in 2012 at the University of Wyoming, where he worked with partners in the Wyoming Cooperative Fish and Wildlife Research Unit, the Wyoming Game and Fish Department, the U.S. Fish and Wildlife Service, and a number of other stakeholders, to better understand wolf-elk interactions in the Absaroka Mountains of northwest Wyoming. He is currently a research associate with the Wyoming Migration Initiative. Prior to receiving his ecological training, Arthur worked as a falconer and raptor biologist in Europe, the U.S., and Central America.
