Amphibians fill many niches within an ecosystem and have important interactions with other species in their habitats. In this study, wood frog (Lithobates sylvaticus) tadpole growth and development was monitored until metamorphosis under four different leaf litter treatments; red oak (Quercus rubra), red maple (Acer rubrum), American beech (Fagus grandifolia), and a mixture of the three in artificial pools that simulated their typical vernal pool habitat. While tadpole size, morphology, and developmental stage changed significantly over time, there were no significant effects of leaf litter treatment, nor were there significant time*treatment interaction effects. Following completion of the experiment, leaf chemistry analyses were also conducted to compare biochemical characteristics associated with different leaf litter treatments that might have implications for tadpole populations. Of the biochemical analyses, % polar extractives, % lignin, lignin:N, and % C were significantly different among treatments. Thus, despite leaf litter differences, tadpoles showed no significant treatment effects. These data indicate that wood frog tadpoles exhibit broader plasticity relative to vernal pool conditions than might be expected. Ultimately, this may make L. sylvaticus more resilient to changing upland forest communities, particularly with respect to tree species present.
