The presence of predators can induce changes in the morphology and behavior of the potential prey. In this study, we examined the effects of different predator-induced changes in water chemistry experienced during the egg stage on larval development in the Gray Treefrog, Hyla versicolor. The potential predators of amphibian eggs and tadpoles used in this study included larval odonates, crawfish, and leeches. Tadpoles from eggs exposed to leech-induced changes in water chemistry were consistently smaller throughout their larval development than the tadpoles in the control and other potential predator treatments. Size at metamorphosis did not differ significantly among treatments, but the tadpoles in the leech treatment were significantly older at metamorphosis than tadpoles in the other treatments. These results highlight some of the potential fitness consequences for larval H. versicolor that received predator cues during the egg stage.
