So far, most activated defenses have been discovered in algae, while very few examples of this strategy have been described in sessile marine invertebrates [ 27 ]. Simulated predation increased the antimicrobial activity of Aplysinella sp. By converting inactive or less active precursors to highly active defense metabolites only upon tissue damage and locally restricted to the wounded tissue, the risk of autotoxicity by the conversion products can be alleviated. Microbial attacks are especially likely in aquatic systems, where microbial densities are much higher 10 4 7 cells ml -1 than atmospheric densities [ 44 ]. No external chemical cues are required in contrast to induced defense.

However, induced defenses were not investigated in their study. Activated defensecan be regarded as specialised form of a constitutive defense.
While in tropical regions fishes are the dominant predators on reefs, temperate systems are predominantly characterised by a mesopredator community of crustaceans, sea urchins or gastropods [ 26 ]. Activated chemical defenses in tropical versus temperate seaweeds.
It would be interesting to conduct a similar study in temperate regions, where predator densities are more molid and the dominant predator groups consist of mesopredators like sea urchins, crustaceans and gastropods.

However, the evolution of inducible defenses against predation requires special ecological conditions reviewed in [ 207172 ].

Prey organisms may rely on specific chemical cues to ensure that defenses are only induced when predation risk is high [ 43 ].
Additionally, we tested if these mechanisms are also used to boost antimicrobial activity to avoid bacterial infection. P-values indicate the result of the pair wise analysis Wilcoxon’s signed rank test.
