TL;DR: The status, threats, and ecological importance of the 31 largest mammalian carnivores globally are reviewed and a Global Large Carnivore Initiative is proposed to coordinate local, national, and international research, conservation, and policy.
Trophic cascades : the primacy of trait-mediated indirect interactions
TL;DR: It is shown that simple trade-off behaviour can lead to both positive and negative indirect effects of predators on plant resources and hence can explain considerable contingency on the nature and strength of cascading effects among systems.
Trophic cascades in terrestrial systems: a review of the effects of carnivore removals on plants.
TL;DR: Trophic cascades in terrestrial systems, although not a universal phenomenon, are a consistent response throughout the published studies reviewed here, and this analysis suggests that they occur more frequently in terrestrial Systems than currently believed.

Behaviorally mediated trophic cascades : Effects of predation risk on food web interactions
TL;DR: In this paper, the authors evaluated the impact of predator manipulations on trophic cascades in an old-field system composed of herbaceous plants, grasshoppers, her-bivores, and spider predators.
Effects of Predator Hunting Mode on Grassland Ecosystem Function
TL;DR: A 3-year experiment in grassland mesocosms revealed that actively hunting spiders reduced plant species diversity and enhanced aboveground net primary production and nitrogen mineralization rate, whereas sit-and-wait ambush spiders had opposite effects.
