Bite-DNA Shows Substantial Browsing on Willows (<i>Salix</i> spp.) by North American Bison in Yellowstone National Park. [PDF]

Ecol Evol
Riparian willows in Yellowstone National Park are shaped by ungulate browsing, but species‐specific contributions remain unclear. Using bite‐DNA metabarcoding of browsed willow twigs across six northern range sites, we found that American bison were the most frequent browsers, exceeding elk and often mule deer.
