Interactions among terrestrial carnivores involve a complex interplay of competition,
predation and facilitation via carrion provisioning, and these negative and positive pathways …

Few concepts in ecology have been so influential as that of the trophic cascade. Since the
1980s, the term has been a central or major theme of more than 2000 scientific articles …

There is growing recognition of the important roles played by predators in regulating
ecosystems and sustaining biodiversity. Much attention has focused on the consequences of …

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 …

Trophic cascades—the top-down regulation of ecosystems by predators—are an essential
aspect of ecosystem function and well-being. Trophic cascades are often drastically …

The vast scope of conservation problems has forced biologists and managers to rely on"
surrogate" species to serve as shortcuts to guide their decision making. These species …

Recent advances highlight the potential for predators to restore ecosystems and confer
resilience against globally threatening processes, including climate change and biological …

Carnivore guilds play a vital role in ecological communities by cascading trophic effects,
energy and nutrient transfer, and stabilizing or destabilizing food webs. Consequently, the …

Limiting similarity theory predicts that competing species must segregate along one or more
dimensions of their ecological niche in order to coexist. In predator communities …

Top‐order predators often have positive effects on biological diversity owing to their key
functional roles in regulating trophic cascades and other ecological processes. Their loss …
