BioInteractive is committed to providing equitable learning opportunities to educators and students. This video follows ecologist Caitlin O'Connell-Rodwell, who is studying how elephants can communicate over long distances using low-frequency sounds that travel both in the air and through the ground. Shane Campbell-Staton of Princeton University, co-lead author of the new paper, has spent his career studying the ways that humans force such evolutionary changes across the tree of life. Like other places that had undergone intense poaching, Gorongosas female elephants exhibited an abnormally high proportion of tusklessness. This is a beautiful study that is certain to become a textbook example of how intense human exploitation of wildlife can rapidly change the natural world, says Jeffrey Good, a mammalian evolutionary geneticist at the University of Montana, who was not involved in the research.

Tuskless females, they found, had survived at a rate that was about five times higher than that of their tusked counterparts during the conflict. But the proportion of tuskless elephants has increased in some populations. Working in Gorongosa National Park, Mozambique, Dr. Joyce Poole and colleagues make a striking observation: many female elephants lack tusks. a.
