Restoration of Riparian Areas Following the Removal of Cattle in the Northwestern Great Basin

Creator:: Batchelor, Jonathan L., Ripple, William J., Wilson, Todd M., and Painter, Luke E.
Abstract:: We assessed the effects of the elimination of livestock in riparian systems at Hart Mountain National Antelope Refuge in southeastern Oregon, 23 years after the removal of cattle grazing, using 64 photos taken before grazing was removed compared with later retake photos. Two methods were used for this assessment: (1)...

Wolves and the Ecology of Fear: Can Predation Risk Structure Ecosystems?

Creator:: Ripple, William J. and Beschta, Robert L.
Abstract:: We investigated how large carnivores, herbivores, and plants may be linked to the maintenance of native species biodiversity through trophic cascades. The extirpation of wolves (Canis lupus) from Yellowstone National Park in the mid-1920s and their reintroduction in 1995 provided the opportunity to examine the cascading effects of carnivore–herbivore interactions...

Wildlife Encounters by Lewis and Clark: A Spatial Analysis of Interactions between Native Americans and Wildlife

Creator:: Laliberte, Andrea S. and Ripple, William J.
Abstract:: The Lewis and Clark journals contain some of the earliest and most detailed written descriptions of a large part of the United States before Euro-American settlement.We used the journal entries to assess the influence of humans on wildlife distribution and abundance. Areas with denser human population, such as the Columbia...

Towards a cohesive, holistic view of top predation: a definition, synthesis and perspective

Creator:: Sergio, Fabrizio, Schmitz, Oswald J., Krebs, Charles J., Holt, Robert D., Heithaus, Michael R., Wirsing, Aaron J., Ripple, William J., Ritchie, Euan, Ainley, David, Oro, Daniel, Jhala, Yadvendradev, Hiraldo, Fernando, and Korpimäki, Erkki
Abstract:: Research on the ecology of top predators – upper trophic level consumers that are relatively free from predation once they reach adult size – has provided regular contributions to general ecology and is a rapidly expanding and increasingly experimental, multidisciplinary and technological endeavour. Yet, an exponentially expanding literature coupled with...

Trophic cascades linking wolves (Canis lupus), coyotes (Canis latrans), and small mammals

Creator:: Miller, Brian J., Harlow, Henry J., Harlow, Tyler S., Biggins, Dean, and Ripple, William J.
Abstract:: When large carnivores are extirpated from ecosystems that evolved with apex predators, these systems can change at the herbivore and plant trophic levels. Such changes across trophic levels are called cascading effects and they are very important to conservation. Studies on the effects of reintroduced wolves in Yellowstone National Park...

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....

Linking Wolves and Plants: Aldo Leopold on Trophic Cascades

Creator:: Ripple, William J. and Beschta, Robert L.
Abstract:: Aldo Leopold, perhaps best known for his revolutionary and poignant essays about nature, was also an eloquent advocate during the 1930s and 1940s of the need to maintain wolves and other large carnivores in forest and range ecosystems.He indicated that their loss set the stage for ungulate irruptions and ecosystem...

The Rise of the Mesopredator

Creator:: Prugh, Laura R., Stoner, Chantal J., Epps, Clinton W., Bean, William T., Ripple, William J., Laliberte, Andrea S., and Brashares, Justin S.
Abstract:: Apex predators have experienced catastrophic declines throughout the world as a result of human persecution and habitat loss. These collapses in top predator populations are commonly associated with dramatic increases in the abundance of smaller predators. Known as “mesopredator release,” this trophic interaction has been recorded across a range of...

Widespread Mesopredator Effects After Wolf Extirpation

Creator:: Ripple, William J., Wirsing, Aaron J., Wilmers, Christopher C., and Letnic, Mike
Abstract:: Herein, we posit a link between the ecological extinction of wolves in the American West and the expansion in distribution, increased abundance, and inflated ecological influence of coyotes. We investigate the hypothesis that the release of this mesopredator from wolf suppression across much of the American West is affecting, via...

Carnivore conservation needs evidence-based livestock protection

Creator:: van Eeden, Lily M., Eklund, Ann, Miller, Jennifer R. B., Lopez-Bao, Jose Vicente, Chapron, Guillaume, Cejtin, Mikael R., Crowther, Mathew S., Dickman, Christopher R., Frank, Jens, Krofel, Miha, Macdonald, David W., McManus, Jeannine, Meyer, Tara K., Middleton, Arthur D., Newsome, Thomas M., Ripple, William J., Ritchie, Euan G., Schmitz, Oswald J., Stoner, Kelly J., Tourani, Mahdieh, and Treves, Adrian
Abstract:: Carnivore predation on livestock often leads people to retaliate. Persecution by humans has contributed strongly to global endangerment of carnivores. Preventing livestock losses would help to achieve three goals common to many human societies: preserve nature, protect animal welfare, and safeguard human livelihoods. Between 2016 and 2018, four independent reviews...
