Prehistoric predators kept large animals in check, shaped ecosystems

OSU Press Release, Oct. 26, 2015: “Large predators can have a major role in limiting their prey and in determining the structure and function of ecosystems,” said Ripple. “But scientists have thought that the largest herbivores, such as elephants, were immune from predation. We now know that’s not the case, and based on these data from the Pleistocene (the epoch which lasted from about 2.5 million to 11,700 years ago), we now think that large carnivores did limit the large herbivores at that time.”

Global decline of large herbivores may lead to an “empty landscape,” scientists say

May 1, 2015. An international team of wildlife ecologists led by William Ripple, Oregon State University distinguished professor in the College of Forestry, conducted a comprehensive analysis of data on the world’s largest herbivores (more than 100 kilograms, or 220 pounds, on average), including endangerment status, key threats and ecological consequences of population decline. They published their observations in Science Advances, the open-access online journal of Science magazine.
