Abstract:
How do plants stop themselves from being eaten by herbivores? As well as using conventional weapons — such as spines and stinging hairs — they may use chemical deterrents (toxins) or employ biological protection (aggressive, territorial ants). In one new study the authors find that, by producing toxins, plants can force grazers to seek out alternative food sources. And in a second, the authors calculate that a plant invests between 0.6 and 5% of its total productivity in its defence mechanism.
