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

Figure 3

Relative speed plotted against other kinematic parameters of C. taunayi on four substrate types with increasing roughness level: polyethylene plastic (PLAS, black squares), wooden board (WOOD, white squares), glued sand (SAND, “+”), and glued gravel (GRAV, “ ”). Relative speed (RSP) is measured in snout-vent length units per second. (a) Relative stride length (RSL, in SVL units), (b) stride frequency (SFR, in s−1), (c) stance duration (STA, in s), (d) swing duration (SWI, in s), (e) stride duration (SDU, in s), and (f) duty factor (DUT). All six Spearman correlations are highly significant ( ).
