Risk level of chemical cues determines retention of recognition of new predators in Iberian green frog tadpoles

摘要: In aquatic environments, many prey rely on chemosensory information from injured (alarm cues) or stressed conspecifics (disturbance to assess predation risk. Alarm cues are considered as a sign of higher risk than disturbance cues. These could be used by learn potential new predators. this study, we tested whether Iberian green frog tadpoles (Pelophylax perezi) exhibited antipredator responses alarm and associate predators with Tadpoles reduced their activity in the presence cues, but only weakly when compared response Also, learned recognize association However, period retention was shorter for Our results indicate that able modify antipredatory behavior according (1) degree implied experimental (2) previous experience chemical predator.
