Time of day tempers tadpoles' response to predators

ratio is higher because that's when the tadpoles do most of their feeding. This favors a quicker return to their pre-cue activity levels."

Considering biorhythmic activity patterns in predator-prey studies is something of a new slant, Fraker said. "The main implication of my results is that prey behavior can be influenced by both external factors---the chemical cues released by the predators---and internal factors such as circadian rhythms. This is important for understanding the mechanisms of prey behavior, which need to be identified in order to make long-term predictions about the effects of prey behavior in ecological communities."
