Abstract
The results of a morphometric analysis of the common vole, Microtus arvalis, were evaluated in this study. Twenty cranial variables were measured and evaluated on 105 skulls (34 males, 71 females) with respect to sex. The main aim of this study was to analyse the presence of sexual dimorphism on skull morphological variation. We showed that values for adult females of M. arvalis were higher than for males. Therefore, the results presented here reveal sexual differences in the measured cranial traits most expressed for the length of the mandible, the length of the lower molar row measured in alveoli and the thickness of the incisor.
