Induced defenses in herbivores and plants differentially modulate a trophic cascade.

abstract：:To elucidate the factors that affect the performance of plants in their natural environment, it is essential to study interactions with other neighboring plants, as well as with above- and belowground higher trophic organisms. We used a long-term field experiment to study how local plant community diversity influenced...
