Arthur is an ecologist who currently works on wildlife migrations and the effects of large carnivores on their prey. He also studies the effects of human disturbance in these systems. Most of Arthur's work is in the northern Rockies and the southern Andes. In Wyoming, he is studying the effects of wolves, bears, and drought on elk populations of the Absaroka Range, and conducting new synthetic research on the nine 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. This work includes the production of a traveling museum exhibit and short film which will tell the story of key wildlife migrations in the GYE.
Arthur completed his Ph.D. in 2012 at the University of Wyoming, where he worked with 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 Range of northwest Wyoming. Prior to receiving his ecological training, Arthur worked as a falconer and raptor biologist in Europe, the U.S., and Central America.
Arthur is also a research associate with the Wyoming Migration Initiative.
