  		Fig. 1. Pictures of Cerrado (A), the Brazilian habitat typical of T. itambere and T. oreadicus, which is characterized by rock outcrops and spaced trees, and Caatinga (B), the Brazilian habitat typical of T. psamonastes, which is characterized by loose sand dunes and scattered vegetation.

  		Fig. 3. Mean net normalized power output at different cycle frequencies (A), fatigue curves (B; given by percentage of power output produced on the first loop) and mean net passive power input measured at different cycle frequencies (C) of iliofibularis of T. itambere (triangles), T. psamonastes (squares) and T. oreadicus (circles). Bars correspond to standard errors, which are presented only for T. oreadicus in A and only for T. itambere in B because they are similar for the three species. In C, standard errors are presented for all species.
