CSU ecologists find national park tourists offer elk and antelope shelter from predators

Outlet:

Prey animals, such as elk and pronghorn, are changing their behavior in close proximity to predictable human activity. A new paper published in PLOS ONE by ecologists at Colorado State University provides a novel investigation of the predator shelter hypothesis by exploring how benign and predictable human activity – such as designated recreation areas, parking lots, and roads – affects the feeding and alert behavior of prey species.
