Phantom Rivers

But where the loud sounds prevailed, only gentle streams flowed by. | For two summers in Idaho's Pioneer Mountains, the roar of rushing white water filled the air. | He and colleagues were testing a hypothesis that the sounds of nature influence where animals lived and how they forage. | There's a lot of research suggesting that human noise negatively affects animals, from communication to foraging to reproduction, and even survival,' Gomes says. | These phantom rivers were part of an experiment led by ecologist Dylan Gomes of Boise State University.
