This dissertation highlights the ability of macroalgae to protect themselves by inducing their palatability changes in the face of consumer attacks. In particular, I examined how macroalgae change their chemical traits in response to herbivore properties classified by herbivore specificity, temporal variation of the herbivores, and feeding cues. Further, I tested macroalgae can predict the herbivory and induce defenses by the cues from an attacked conspecific and a heterospecific species. Finally, I investigated the effective magnitude of the induced responses using non-native macroalgae as well as species-specificity of herbivores. These approaches support that herbivore-induced defenses are not accidental reactions but adaptive options of plants through coevolved history with specific herbivores.
