Fig. 5. Gaits (means ± s.e.m.) and multivariate differences between species during running (A, for all species) and walking (B, for WF) mechanics. Ellipses surround species means that are not significantly different. (A) When using running mechanics Tupinambis, Eumeces sch. and Eublepharis differed in using significantly larger high duty factor trots than the remaining species. (B) During walking mechanics species clustered into three statistically distinct gait groups. Ameiva and Acanthodactylus use a fast walking gait (lower duty factors) but diverge toward more lateral (lower limb phase) and diagonal (higher limb phase) sequence gaits, respectively. The remaining species clustered into a single group that uses a higher duty factor trotting gait while walking.
