Patterns of variability in mineralization of the primate femoral diaphysis.
The purpose of this research was to study intra- and interspecific variability in mineral density in the femoral diaphysis of nonhuman primates. Four hundred five sections were taken from five sites along the femoral diaphysis of 34 macaques (Macaca sp.), 24 squirrel monkeys (Saimirisciureus), and 23 tamarins (Saguinus labiatus). The mineral density at eight positions around each section was measured. Analysis of variance indicated significant (p less than 0.05) interactions among species, sex, cross sectional levels, and positions within each level. Both Macaca and S. sciureus showed sexually dimorphic patterns of mineral distribution. S. labiatus exhibited no sexual dimorphism in distribution, but was sexually dimorphic in density magnitude. No significant dimensional differences in density were found among species, though significant differences in pattern were evident. Highly significant differences (p less than 0.01) were found among cross sectional levels and among positions within the levels within each species.
