Effects of Surface Roughness on the Locomotion of a Long-Tailed Lizard, Colobodactylus taunayi Amaral, 1933 (Gymnophthalmidae: Heterodactylini)

Table 2

Results of linear regression between the logarithm of means of nine kinematic variables and the logarithm of roughness for four substrates (codes as in Table 1). Coefficients of determination 𝑟² and their associated probabilities 𝑃 are presented. Sample size is 𝑛=4 for each linear regression. Absolute residuals of these linear regressions for each substrate are also shown, with small values (<0.01) in bold.
