Condition of Populations and the Conservation Status of the Vipera renardi (Christoph, 1861) (Reptilia, Serpentes) in the Saratov Region

The historical and modern distributions of the steppe viper (Vipera renardi) in the territory of the Saratov region are analyzed. The condition of its local populations in various parts of the area is shown. The ne-cessity of monitoring and determining its conservation status in the publication of the Red DATA Book of the Saratov Region are established.

SIZE-WEIGHT AND SEXUAL STRUCTURE OF PELOPHILAX RIDIBUNDUS AND BOMBINA BOMBINA (AMPHIBIA, ANURA) POPULATIONS IN THE FLOODPLANE OF THE MEDVEDITSA RIVER (SARATOV REGION)

The size, weight and sexual structure of Pelophylax ridibundus and Bombina bombina populations was analyzed during their spawning migrations in 2013 - 2015 in four lakes of the Medveditsa River flood-plane (Saratov Region, Lysogorsky District). The body length of Pelophylax ridibundus males ranged from 29.3 to 101.3 mm (the weight from 2.10 to 152.2 g), and that of females did from 36.1 to 120.2 mm (the weight from 4.45 to 181.0 g); for Bombina bombina males - from 25.4 to 50.6 mm (the weight from 1.06 to 8.5 g), and that of females from 32.1 to 49.7 mm (the weight from 2.64 to 8.43 g).

NATURE PROTECTION STATUS OF AMPHIBIANS AND REPTILES IN SARATOV REGION

On the basis of modern field surveys, collection data, and analysis of the literature data, a list of amphibian and reptile species recommended for inclusion into the 3rd edition of the Red Book of the Saratov Region was compiled. It contains 7 species of the batrachofauna and herpetofauna of the region, belonging to 3 groups, 5 families, and 6 genera. We offer to add 1 new species into the Book and to exclude 1 species, and there appeared prerequisites for revision of the existing protection status of 2 taxa.

LONG-TERM DYNAMICS OF THE SIZE-WEIGHT AND SEXUAL STRUCTURE IN POPULATIONS OF PELOBATES FUSCUS (ANURA, PELOBATIDAE) IN THE MEDVEDITSA RIVER VALLEY (SARATOV REGION)

The size, weight and sexual structure of several populations of mature individuals of the common spadefoot was analyzed in five lakes of the Medveditsa floodplain (Saratov Region, Lysogorsky District) in 2009 - 2016. The body length of the males participating in reproduction ranged from 29.0 to 56.0 mm (the weight from 2.35 to 20.87 g), and that of females ranged from 29.3 to 59.2 mm (the weight from 2.64 to 22.33 g).
