Evidence varies on how subsidies affect trophic cascades within recipient food webs. This could be due to complex nonlinearities being masked by single-level manipulations (presence/absence) of ...

Following the reintroduction of wolves to Yellowstone National Park in 1995-97, the regrowth of aspen trees became a worldwide story, highlighting the importance of large predators. The wolves ate elk ...

Purpose: To introduce the idea of indirect effects of predator on prey by changing prey behavior, and of trophic cascades - effects of predators on primary producers; to construct a flow diagram of ...

1. Resource subsidies often weaken trophic cascades in recipient communities via consumers' functional response to the subsidies. Consumer populations are commonly stage-structured and may respond to ...

New research questions the long-held theory that reintroduction of such a predator caused a trophic cascade, spawning renewal of vegetation and spurring biodiversity. Yellowstone’s ecological ...

The release of gray wolves in Yellowstone decades ago still stands as one of the few examples of a predator reintroduction, and the lessons learned continue to be debated. New projects aim to do it ...

A new study reveals the profound ecological effects of wolves and other large carnivores in Yellowstone National Park, ...

The commonly held claim that wolves reintroduced into Yellowstone National Park in the mid-1990s spearheaded a "trophic cascade" of ecological restoration, as some studies indicated, is unfounded, ...

New research has demonstrated the powerful impacts the reintroduction of predators can have on an ecosystem. The presence of wolves in Yellowstone National Park has driven a cascading effect that has ...

Purpose: To practice interpreting graphical data; to use the data to address the question of why browsing by elk in Yellowstone was so intense during the 20th century. Why was elk browsing on ...
