during the past few decades, the gray wolf (Canis lupus) now thrives in the U.S., and since 2003 the U.S. Fish and Wildlife Service has been trying to move the top predator off the endangered species list — a plan opposed by groups that believe the wolves are susceptible to being overhunted [see «Out of the Woods»; SciAm, April 2003].
