Latent alarm signals: Are they present in vertebrates?
Latent alarm signals seem to be present in vertebrates, especially in tadpoles of frogs, and the existence of such signals may explain some basic evolutionary questions in the relationships between predators and prey. The presumable inactive compounds in question may be activated by the bacterial flora within the gut of predators, explaining why taxonomically different predators may release diverse responses within one single prey species. Knowing the exact source of the alarm signals will be of utmost importance for future work within predator-prey interactions.
