Water-borne cues of a non-indigenous seaweed mediate grazer-deterrent responses in native seaweeds, but not vice versa.

Plants optimise their Shoulder Bags resistance to herbivores by regulating deterrent responses on demand.Induction of anti-herbivory defences can occur directly in grazed plants or from emission of risk cues to the environment, which modifies interactions of adjacent plants with, for instance, their consumers.This study confirmed the induction of a
