    There are plenty of things about this study that are not so feasible for us at the moment, but... this general area: plant pathology, interactions between native and non-native plants & crops... is a very cool area to explore that would present some feasibility for us.

  • When leaf beetle larvae eat goldenrod leaves, the plant emits a chemical that informs the insect that the plant is damaged and is a poor source of food. These airborne chemicals, called volatile organic compounds (VOCs), are also picked up by neighboring goldenrod plants, prompting them to produce their own defenses against the beetle larvae. In this way, goldenrod move herbivores on to neighbors, and distribute damage.

      Are these VOCs (volatile organic compounds) detectable by us? If not detectable, they can we identify them... and then produce or purchase those chemicals to test their effects on plant responses?
  • start producing defensive compounds that help the plants fight off insect pests.

      It seems to me that I remember hydrogen peroxide being one of these signaling chemicals (at least from one part of a plant to another).
  • When no neighbors are present, the plants don't resort to accelerated growth when eaten and the chemical responses to herbivores are markedly different, though they still tolerate quite high amounts of herbivory.
  • ...5 more annotations...
  • Neighboring goldenrod also exhibit intelligence when they perceive VOCs that signal the presence of a pest. "The volatile emission coming from a neighbor is predictive of future herbivory," Kessler said. "They can use an environmental cue to predict a future situation, and then act on that."
  • Applying the concept of intelligence to plants can inspire fresh hypotheses about the mechanisms and functions of plant chemical communication, while also shifting people's thinking about what intelligence really means, Kessler said.
  • "What that means is, the brain in the plant is the entire plant without the need of central coordination," Kessler said.
  • "They can smell out their environment very precisely; every single cell can do it, as far as we know,"

    "When goldenrod is eaten by herbivores, it adapts its response based on whether or not another plant is nearby."

  • However, this coding mechanism is not necessarily transferable to other locust species.

      Why is it only a thing for migratory locaust?
