What exactly does a tree do once it’s been notified of danger? “Oh shit, I better tree even harder”
Acacia trees increase tannin level in their leaves. Giraffes don't like the bitterness and stop eating it.
The emitted ethylene will only move with the wind. Giraffes counter that by moving upwind, targeting trees that have not been 'warned'.
Thats crazy cool
