How Wolves Completely Changed Yellowstone Rivers—A Biologist Explain
From Forbes.com:
Bring wolves back to a landscape, and eventually, the surrounding rivers will begin to change in response. This claim has proliferated online, mostly because it feels too poetic to be true. And yet, ecologists have spent the better part of the last thirty years documenting exactly that.
Wolves, of course, aren’t physically reshaping rivers with their paws. What they alter is behavior, pressure, movement and fear. Those changes ripple outward through ecosystems in ways that can ultimately affect streambanks, vegetation, wetlands and water flow itself.
