Sexual dimorphism in the size of the buccal teeth of three representatives of the genus Vulpes
The article carries out the analysis of sexual dimorphism in the size of the buccal teeth of red fox, arctic fox and corsac in Northern Eurasia. It gives the limits of variability in absolute sizes (length and width) of the buccal teeth for males and females of each species. The paper analyzes the coefficient of variation in the size of the buccal teeth of males and females of each species, as well as the coefficient of sexual dimorphism in the size of the buccal teeth of red fox, arctic fox, and corsac. It is shown that there are no significant differences in the absolute size of teeth between males and females within each species. With the exception of M2 in red foxes and P1 in arctic foxes, there were no significant differences in the degree of variation in tooth size of females and males. The teeth of foxes are characterized by a low degree of variability in size. There are no significant differences between the indices of sexual dimorphism of red fox, arctic fox, and corsac.
