ow sessile plants defend
themselves against attack
from herbivores has been
the subject of much in-
vestigation over the past century.
Early observers noted that insect
taxa tended to attack plants with
similar tissue chemistries. Based
on observations of the deterrent
and protective properties of phyto-
chemicals, Ehrlich and Raven1

bivory resulted in the codiversifi-
cation of plant and insect groups.
In the past decade, researchers
have increasingly focused on
alternative defensive traits of
