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'.
Obviously, the trees counter this by always growing downwind.
I see someone's read The Hidden Life of Trees!
Thats crazy cool
but why are the giraffes seen as a danger? would they kill the tree if they ate too many leaves?
If someone started eating your hair, would you not be scared?
well my hair is not for eating
