Fig. 12. Principle component 2 (PC2) versus principle component 1 (PC1) from a single analysis of 15 kinematic variables of A. sagrei for all strides observed on each perch diameter and incline. Each point is an individual stride (N=185), and the points are separated by incline: level (A), uphill 45° (B) and 90° (C). Red circles, yellow squares, green triangles, blue inverted-triangles and black hexagons represent strides on 1, 3, 6, 10 cm and flat surfaces, respectively. Table 5 provides the loadings for the principle components.
