FIGURE 3. Principal components analysis of 10 morphometric and eight meristic characters comparing G. c. australis (red) and G. cuia (blue). A. Principal component one explains 43.2% of the variance and PC2 explains 14.2% of the variance in the comparison between G. c. australis (n=28) and G. cuia (n=56). Note the relatively large separation in shapespace between species. B. Principal component one explains 49.9% of the variance and PC2 explains 17.8% of the variance in the comparison between G. c. australis (n=28) and G. cuia (n=45). Note the relatively large separation in shapespace between species.
