WebSep 11, 2024 · Allometry was found to have a strong and significant effect across the whole skull (n = 70, R 2 = 0.38, p = 0.001). The difference in allometric slope between males and females was found to be non-significant (R 2 = 0.01, p = 0.635), suggesting shared allometric trajectories.

WebThis allometry is detected as β ≠ 1, where β is the slope of a model II regression of log (male size) on log (female size). Most frequently, β exceeds 1, indicating that SSD increases with size where males are the larger sex, but decreases with size where females are larger, a trend formalized as “Rensch's rule.”
