Title Clemente_Supp_data1
Downloaded 20 times
Description Clemente_Supp_data1.csv contains data for the horizontal body center of mass and snout vent length for 124 species of lizards. Species names are as formatted in the Pyron et al. (2013) phylogeny. BCOM.hip represents the mean horizontal position of the body center of mass forward from the hip. SVL is the mean snout to vent length for each species measured. Two additional columns classify bipedal locomotion. Column 4 (bipedal) was used in the study and is divided into species for which bipedal locomotion has been observed (yes), with all other species being placed in the unknown category (unknown). Column 5 (bi.cat) is similar with the exception that species are divided into bipedal, where bipedalism is observed (yes), where only quadrupedal locomotion was observed after high speed filming and observation (no), and unknown where it is ambiguous (unknown).

Title Clemente_Supp_data2
Downloaded 14 times
Description Clemente_Supp_data2.csv contains accelerations for bipedal, quadrupedal and transitional strides for each species. Column 1 contain species names, formatted as in the Pyron et al. (2013) phylogeny. Column 2 contains mean acceleration during the stride. Column 3 contains the gait category for each stride as quadrupedal (0), transitional (0.5) or bipedal (1.0).

Title Clemente_Supp_data3
Downloaded 12 times
Description Clemente_Supp_data3.csv contains the stride kinematics used to determine predicted threshold kinematics for each species. Column 1 contain species names, formatted as in the Pyron et al. (2013) phylogeny. Column 2 contain the average position of the foot relative to the hip during the stance phase (xfh). Column 3 contains the average hip height during the stance phase used to approximate the vertical COM (ybc). Column 4 contains hind limb length (HLL) used to standardize kinematics for size. Column 5 contains the horizontal BCOM forward of the hip (BCOM). Pyron, R. A., F. T. Burbrink, and J. J. Wiens. 2013. A phylogeny and revised classification of Squamata, including 4161 species of lizards and snakes. BMC evolutionary biology 13:93.
