On the definition of variables in studies of primate dental allometry

摘要: Cranial and dental measurements are taken on 253 adult female primates from 32 species. Regression equations calculated to determine allometric relationships between anterior tooth size, posterior body size. When cranial length or skull is used as the measure of general results differ when weight reference dimension. Similarly, using different definitions size (such mandibular second molar maxillary postcanine area) alters substantially. The same occurs with It has been common in studies primate allometry generalize specific variables measured broad functional interpretations. However, highly correlated cannot be substituted one for another analyses without important changes equation. Interpretation data more restricted precise a particular study than generally recognized.
