Figure 4. Three terrestrial locomotor modes performed by Alticus arnoldorum.

a, Hopping, b, jumping, and c, climbing. d, Results of a discriminatory analysis on four principal components derived from two principal components analysis (PCA) models of preparatory and propulsive kinematics. All three locomotor modes are distinct (Wilks' Lambda: P<0.0001; ANOVA: F = 159.37, P<0.0001) and categorized with 93.7% accuracy (14 of 15 correct). See Tables 1 and S1 for a list of variables included in the PCA models.
