FIG. 9 in Miniaturization in Direct-Developing Frogs from Mexico with the Description of Six New Species

FIG. 9.—Body size and shape variation within the Craugastor mexicanus series as depicted by principal components analysis of 15 linear measurements. Principal component scores for the first two components (left) are depicted along with their residuals (right). Large-bodied species are those with an adult body size>20 mm SVL (C. mexicanus, C. montanus, C. omiltemanus, C. saltator), and small-bodied species are those with adult body sizes <20 mm (C. bitonium, C. candelariensis, C. cueyatl, C. hobartsmithi, C. polacalvus, C. portilloensis, C. pygmaeus, and C. rubinus).
