Features of newborn's morphological parameters and female's reproductive characteristics of Vipera Renardi from the Ulyanovsk and Volgograd regions

The comparative characteristic of morphological parameters of newborns and copiousness of females Vipera renardi from Radishchevsky area of the Ulyanovsk region and Kamyshinsky area of the Volgograd region is resulted in article. Within each point of research the differences between neonatal males and females are revealed only on tail length L.cd and index L.corp/L.cd whereas distinctions on body mass and total length is not revealed. Statistically significant distinctions in mass, total length and fatness of neonatal vipers from compared geographical points are noted. Average fruitfulness of females is calculated and correlation dependences of quantity of newborn on the female length are resulted.
