| Abstract | Organisms that possess complex life cycles often experience carry-over effects of larval phenotypic plasticity into their juvenile and adult life stages. Predation risk during the larval stage has been shown to affect juvenile wood frog (Rana sylvatica) morphology under laboratory conditions. This study sought to determine the effects of predation on juvenile wood frogs emerging from four different vernal ponds. Hind limb length, forelimb length, head width and body width of juveniles were measured and correlated with predator density at each pond site. Predation density was not found to significantly affect juvenile morphology. However, the data suggest that physiological constraints may have prevented the evolution of extreme phenotypes in juvenile frogs in response to carry-over effects of phenotypic plasticity experienced in the larval stage. |
