dc.description.abstractPlethodontid salamanders have a myriad of defense mechanisms with which to escape predation. One of the most poorly understood mechanisms is jumping, which is driven by lateral body bending; rapid straightening of the body propels the salamander into the air. One previous examination of jumping in one plethodontid salamander found little evidence of ontogenetic changes in the mechanics of jumping. Here, we investigate jumping in six species of plethodontid salamanders, across a wide array of body sizes. Comparing morphological and kinematic variables, jump height scaled with body size and forelimb length. Species differed in morphology, and when comparing kinematic variables across species, only bending duration differed. The lack of scaling patterns leads to several hypotheses, and further investigation of the morphology of the axial musculature is required.en_US
