Jack rabbits living in the Greater Yellowstone Ecosystem disappear

A new study by Wildlife Conservation Society has found that jack rabbits living in the Greater Yellowstone Ecosystem have disappeared. According to the study's lead author, Dr. Joel Berger, a Wildlife Conservation Society conservationist, and professor at the University of Montana, no one knows what caused the rabbits to disappear. Dr. Berger believes that the absence of jack rabbits may be causing elevated predation by coyotes on juvenile elk, pronghorn and other ungulates. Dr Berger recommends reintroduction and believes reintroduction may result in the establishment of dynamic ecological processes that were intact before rabbits vanished from the ecosystem. The details of the study appears in the journal Oryx
