Are wolves saving Yellowstone's aspen? A landscape-level test of a behaviorally mediated trophic cascade
Matthew J. Kauffman, Jedediah F. Brodie, Erik S. Jules
2010, Ecology (91) 2742-2755
Behaviorally mediated trophic cascades (BMTCs) occur when the fear of predation among herbivores enhances plant productivity. Based primarily on systems involving small-bodied predators, BMTCs have been proposed as both strong and ubiquitous in natural ecosystems. Recently, however, synthetic work has suggested that the existence of BMTCs may be mediated by...
