• Resumen

  • Erick Lundgren of Arizona State University and his colleagues have studied the ranges of 76 species of large plant-eating mammals. They found 22 with significant populations outside their native range. Ten of those are extinct or threatened back home. For instance, there are an estimated 5 million wild donkeys around the world, but only a few hundred of their pre-domesticated ancestors, the African wild ass. Lundgren says such newcomers should be seen as nature's comeback.
