Predation risk and jumping behavior in Pseudopaludicola aff. falcipes tadpoles

Tadpoles of Pseudopaludicola aff. falcipes are capable of jumping out of small temporary puddles where they occur. In this system, odonate naiads are the main predators. Considering the hypothesis that jumping behavior represents an antipredator tactic, we addressed the following predictions: 1) tadpoles will jump more frequently from puddles with predators than from puddles without predators; 2) tadpole mortality will increase if tadpoles are...
