When insects nibble on sagebrush leaves, the plants respond by releasing volatile organic compounds (VOCs) into the air. These airborne signals are picked up by nearby sagebrush, which then activate their own chemical defenses before the herbivores even arrive.
This remarkable early-warning system helps reduce damage across the population. Researchers have observed this sophisticated communication network in wild sagebrush throughout North America. Read study
