On the Distribution of the European Common Spadefoot, Pelobates fuscus (Pelobatidae, Amphibia) in Moscow

The European common spadefoot, Pelobates fuscus, has not been observed in Moscow since the end of the 20th century. The species is listed in the Red Data Book of Moscow (2017) as endangered or completely extinct. The paper presents new findings of P. fuscus on the territory of the city, namely, in the “Moskvoretskiy” Natural-Historical Park and the “Kosinskiy” Natural-Historical Park in August 2020.

Rediscovery of the Caucasian Smooth Newt, Lissotriton lantzi (Wolterstorff, 1914) (Salamandridae, Amphibia) in North Ossetia–Alania

Lantz’s newt, or the Caucasian smooth newt, Lissotriton lantzi, is an endemic species for the Caucasian mountain-forest belt. In North Ossetia–Alania, only 4 findings of this newt are known in the Prigorodniy, Alagirskiy and Irafskiy districts. Since 1983, there has been no new information about any findings of L. lantzi in this region. On August 4, 2020, L. lantzi larvae were caught in a lake on the left shore of the Urukh River in the Irafskiy district. Newts live here in a beech forest at an altitude of 810 m. The authors assume that L.

Current Distribution and Some Features of the Biology of the Common Lizard – Zootoca vivipara (Lichtenstein, 1823) (Lacertidae, Reptilia) in the Saratov Region

On the territory of the Saratov region, the populations of viviparous lizards mainly inhabit the river valleys of the Don basin. Most populations were found along the sides of lake basins. In the conditions of the drying up of floodplain lakes, some populations have degraded while the others have moved to river-bed biotopes. The reduction in the number of local populations has led to their increased disconnection.

On the Distribution of Eremias arguta deserti (Gmelin, 1789) (Reptilia, Lacertidae) in Kabardino-Balkaria

The paper discusses the distribution of the Steppe Runner (Eremias arguta) in the North Caucasus, in the territory of Kabardino-Balkaria. A new find of the species from the Geduko natural boundary in the Baksan District is presented.

Data on the Distribution of the Crimean Wall Lizard, Podarcis tauricus (Pallas, 1814) (Sauria: Lacertidae), in the North-Western Black Sea Region (Ukraine)

Novel data on the distribution, habitats and population density of the Crimean (Balkan) wall lizard, Podarcis tauricus (Pallas, 1814) in the Odessa Province of the Ukraine are given. For the majority of the localities known from the literature data in the Pre-Danube Region, the current dwelling of the species was confirmed, and its population density over limited areas remains quite high, namely: from 5–10 to 70–100 specimens/1000 sq. m. The northernmost point of the P.

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.
