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.

A New Record of Lacerta media Lantz et Cyrén, 1920 (Reptilia, Lacertidae) in Talysh

The paper discusses the spread of the medium lizard, Lacerta media, in the Talysh Mountains on the territory of Republic of Azerbaijan. Earlier, findings of this species were known in the North-Western part of the Talysh only. A new record of the medium lizard from the Sym village in the Astara District of Azerbaijan is presented.

DISTRIBUTION AND REPRODUCTION ECOLOGY OF THE SIBERIAN SALAMANDER (SALAMANDRELLA KEYSERLINGII) IN THE NORTHEAST OF EUROPEAN RUSSIA

Data on the findings of the Siberian salamander over the territory of the European Russian Northeast are summarized. This species is shown to be rare here and to be distributed locally. Three types of spawning reservoirs have been identified, namely: lowland marshes, puddles along the edges of transitional marshes, and roadside ditches. Reproduction begins immediately after snow melting and the appearance of open water. Significant correlation links between the dates of the egg lying onset, average air temperature in April and the dates of snow melting in burs are noted.

MATERIALS ON THE DISTRIBUTION, BIOTOPICAL AND VERTICAL PLACEMENT OF THE SAND LIZARD (LACERTA AGILIS LINNAEUS, 1758) IN ITS SOUTHEAST HABITAT

Data on the spread of the sand lizard (Lacerta agilis Linnaeus, 1758) in the southeast area of its habitat, in the adjacent parts of Kazakhstan, Kyrgyzstan and China have been generalized. Cadastral maps with the exact location of 217 occurrences have been compiled. The habitat boundary of the sand lizard in the Southern Balkhash region has been refined. The mountains in the east and southeast of Kazakhstan are an important focus of L. agilis in the country. The maximum limit of the vertical distribution of the species (2,084 m above the sea level) was recorded in the Central Tien Shan.

DISTRIBUTION OF THE «EASTERN» AND «WESTERN» FORMS OF THE MARSH FROG, PELOPHYLAX RIDIBUNDUS, AND THEIR PARTICIPATION IN THE ORIGIN OF HEMICLONAL HYBRIDS, P. ESCULENTUS IN MARI EL REPUBLIC

Molecular-genetic analysis of green frogs (67 individuals of Pelophylax ridibundus and 63 ones of hybridogenic P. esculentus) from Mari El Republic (15 localities) and the Kirov Region (one locality) was performed by two (mitochondrial and nuclear) markers. Some part of the material (66 individuals) was studied by means of DNA flow cytometry. It is shown that in the green frogs living in the northern Middle Volga region, the genetic markers specific for the «western» (the Central European P. ridibundus) form are predominant.

ON THE DISTRIBUTION OF AMPHIBIANS AND REPTILES IN THE EVREISKAYA AUTONOMOUS OBLAST’ (RUSSIA)

The author has collected and integrated records on 7 amphibian species and 9 reptile ones in the Evreiskaya Autonomous Oblast’ (Russian Federation). Most of these species are found to be distributed in the mountain-forest area of the region, which is due to a combination of several factors (temperature limits, the availability of refuges, and food base).
