From: The relationship between bite force, morphology, and diet in southern African agamids
a and c Bar plots represent the correlations observed between the original variables and the scatterplot axes. b Scatterplot of the scores of the four southern African agamid species obtained from partial least-squares (PLS) analysis between absolute head morphological variables (not corrected by size) and indexes of relative importance (IRI) of each prey item. Colour refers to different habitat groups: blue circles, ground dwelling, Agama armata; brown triangles and squares, rock dwelling, A. atra and A. a. distanti respectively; green diamonds, arboreal, Acanthocercus atricollis
