Background/Question/Methods
Prey frequently alter their phenotype in response to perceived predation risk in order to reduce vulnerability. Differences in the costs and benefits of such plastic responses to predators can lead to differences in non-consumptive predator effects. Such differences can occur between taxa or through ontogeny for a given species, and may alter interactions between prey and other species in the food web. Less vulnerable prey may respond less to predator cues compared to vulnerable prey and thus may have higher performance in risky environments. Here we build upon previous research on the tadpoles of two hylid treefrogs, Agalychnis callidryas …
