dc.description.abstractPhenotypic plasticity has been observed in many organisms from mammals to plants. In particular amphibians are susceptible to plasticity before metamorphosis. Hydroperiod (the amount oftime water is present in a pond) is a significant factor in amphibian development. It has been indicated to cause phenotypic plasticity in the head morphology of salamanders. Cannibalistic and typical head morphologies have been recorded in the long-toed salamander Ambystoma macrodactylum. Larval salamanders in both short and long hydroperiod ponds were observed using macro-photography. Geometric morphometries was then used to analyze head shapes. The two sites were sampled throughout the summer of 2003 to view if there was a morphological difference between larval salamanders in long and short hydroperiod ponds. The larval salamanders exhibited typical and non-typical morphologies depending on hydroperiod.
