Fig. 6. Patterns of gait change when shifting from running to walking mechanics in WF lizards. White symbols, walking mechanics (W); black symbols, running mechanics (R). Solid cloud is the ancestral running gait cloud from Fig. 5A. When shifting from running to walking mechanics lizard exhibited four ways of changing position in gait space, based on MANOVAs comparing running to walking gaits for each species: (G1, broken arrows) Varanus and Tracheloptychus switch from the ancestral trotting run to a higher duty factor and lower limb phase trot while walking, (G2, solid arrow) Ameiva exhibits small shifts in limb phase and duty factor in a lateral sequence trot. (G3, dotted arrow) Acanthodactylus maintained a fast diagonal sequence trot and (G4, stippled cloud) Tupinambis, Eumeces sch. and Eublepharis maintained a slow speed high duty factor trot when switching from running to walking.
