Assistant Professor Ryan Long from the Department of Fish and Wildlife Sciences published in Science. Working in Gorongosa National Park, Mozambique, Long and his colleagues found that bushbuck, a forest-dwelling antelope, began to graze the plains after the country's civil war exterminated large predators. In a domino effect, this change in bushbuck foraging behavior altered plant growth on the plain. However, when the researchers mimicked the smell and sounds of predators, bushbuck reversed this behavior, suggesting that the effects of human-caused extermination of big predators can also be reversed if predators are restored.
