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


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.
