Wolves (Canis lupus) were reintroduced to Yellowstone National Park in 1995–1996. We present data on a recent trophic cascade involving wolves, elk (Cervus elaphus), and aspen (Populus tremuloides) in Yellowstone’s northern winter range that documents the first significant growth of aspen in over half a century. Results indicate reduced browsing and increased heights of young aspen during the last 4–5 years, particularly at high predation risk sites (riparian areas with downed logs). In… Expand

Linking wolves to willows via risk-sensitive foraging by ungulates in the northern Yellowstone ecosystem
TLDR
Willow height increases documented in this study appear to have been at least partially due to behaviorally mediated trophic cascades involving wolves and ungulates, via a mechanism of predation risk. Expand
Wolves, elk, willows, and trophic cascades in the upper Gallatin Range of Southwestern Montana, USA
Abstract We summarized the status of wolves (Canis lupus), elk (Cervis elaphus), and woody browse conditions during the 20th century for the upper Gallatin elk winter range in southwestern Montana,Expand
REDUCED COTTONWOOD RECRUITMENT FOLLOWING EXTIRPATION OF WOLVES IN YELLOWSTONE'S NORTHERN RANGE
TLDR
Data from the five sites reported herein along with the results of other studies provide compelling evidence that the absence of wolves in the northern Yellowstone has had a major impact on the recruitment of cottonwood and other woody browse species. Expand
Historic aspen recruitment, elk, and wolves in northern Yellowstone National Park, USA
TLDR
Aspen overstory recruitment ceased during the same years that wolves, a significant source of elk predation, were removed from YNP, finding that a main factor is YNP’s loss of significant predator/prey relationships in the early 1900s. Expand
Predation risk and the functional response of elk–aspen herbivory
TLDR
Anthropogenic burning combined with human and carnivore predation effects on elk (behavioral and numeric) appeared to be important in aspen’s long-term persistence, and its recent decline. Expand
Elk alter habitat selection as an antipredator response to wolves
TLDR
The data support a central portion of the hypothesis that elk antipredator behavior could drive a trophic cascade in the Yellowstone ecosystem, but changes in elk numbers are also likely to have affected elk-plant interactions. Expand
Human Activity Mediates a Trophic Cascade Caused by Wolves
TLDR
Elk population density diverged over time in the two treatments, such that elk were an order of magnitude more numerous in the low- wolf area compared to the high-wolf area at the end of the study, which support the wolf-caused trophic cascade hypothesis. Expand
Wolves and the Ecology of Fear: Can Predation Risk Structure Ecosystems?
TLDR
It is indicated that predation risk may have profound effects on the structure of ecosystems and is an important constituent of native biodiversity. Expand
