Research sheds new light on wolves' impact on Yellowstone ecosystems

(Phys.org)—New research by Colorado State University finds that the removal of wolves from Yellowstone National Park caused complex changes in ecological processes that cannot be simply reversed by wolf reintroduction alone. The research findings are presented in a new paper, "Stream hydrology limits recovery of riparian ecosystems after wolf reintroduction," which is published in Proceedings of the Royal Society B: Biological Sciences and concludes that the effects of apex predator removal are unpredictable and are not symmetrical with the effects of predator reintroduction.
