Escalated antipredator mechanisms of two neotropical marsupial treefrogs
The sequence and intensity of antipredator mechanisms may be displayed according to the risk of predation. We tested this hypothesis using two species of marsupial treefrogs from Brazil's Atlantic Forest. We observed Gastrotheca recava and G. megacephala displaying nine antipredator mechanisms and three types of defensive calls. These behaviours were displayed in an escalated sequence from motionless (passive behaviour) to biting (the most aggressive behaviour). This diversified set of antipredator mechanisms may be related to the interaction between predator and prey at the local scale. The escalated sequence of defensive behaviours should be considered in future studies on anuran-predator interaction.
