Abstract

A morphometric comparison of scapular shape was conducted between twospecies of Peromyscus (P. gossypinus and P. floridanus). Earlier findings suggested that scapulae of adult P. floridanus are relatively more horizontally elongate than those of P. gossypinus and were interpreted as being related to differences in frequency of arboreal climbing. However, adult P. floridanus are significantly larger in body size than adult P. gossypinus. Using traditional methods of analysis and tensor-biometrics, a biostatistical approach to landmark data, we examine whether significant differences in scapular shape exist independently of differences in size. Linear measures of adult P. floridanus are consistently and significantly larger than those of adult P. gossypinus, but larger adult P. gossypinus have the same scapular proportions as smaller adult P. floridanus. Tensor analysis confirmed results of traditional methods indicating that the two groups share a common pattern ofallometry. This work underscores the importance of an allometric approach to assessing the functional implications of variation in morphology.
