Creator:: Halofsky, Joshua S.
Abstract:: According to general top-down trophic theory, in the presence of carnivores, herbivore behavior and/or densities could change and result in an overall decrease in herbivory on plant communities.

Berry-producing shrub characteristics following wolf reintroduction in Yellowstone National Park

Creator:: Beschta, Robert L. and Ripple, William J.
Abstract:: Gray wolves (Canis lupus) were reintroduced into Yellowstone National Park in 1995-96, thus completing the park’s large predator guild. In the fall of 2010, approximately 15 years after wolf reintroduction, we sampled ten genera/species of berry-producing shrubs within 97 aspen (Populus tremuloides) stands in the park’s northern ungulate winter range....
