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.

Shchukinsky Peninsula as a New Habitat of the Grass-snake Natrix natrix (Linnaeus, 1758) (Colubridae, Reptilia) in Moscow

The paper provides new information about the Moscow findings of the grass snake Natrix natrix, listed in the Red Data book of this city. Regular meetings of common grass snakes on the territory of the Shchukinsky Peninsula for a significant period, starting from 2012, indicate its relatively stable, but low population abundance.

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.

Daily Diet of Pelobates fuscus (Pelobatidae, Amphibia) in the Khoper River Floodplain (Saratov Region)

The daily diet of Pelobates fuscus in local populations in the Khoper river floodplain is considered. The absence of gender differences in their daily diet is shown. Most of P. fuscus prey is made up of animals weighing 10–25 mg and having body lengths of 8–18 mm. Hymenoptera (70.8%) and Coleoptera (52.1%) predominate by the number of specimens and by biomass, respectively. The number of daily caught invertebrates usually does not exceed 15. The lowest feed consumption is in April and October, while the highest one is in the summer months.

Notes on the Snakes of the Northern Caucasus

The paper provides new information on the distribution of rare and endangered snakes over the Stavropol Region, namely, Eryx jaculus, Dolichophis caspius, Elaphe sauromates, and Platyceps najadum.

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 Eggs Re-Laying of Greenbelly Lizards from the Darevskia (Chlorogaster) Complex (Reptilia, Lacertidae)

The paper discusses cases of eggs re-laying in two lizard species from the Darevskia (chlorogaster) complex. A male and a female of D. Chlorogaster were captured on 22 March, 2016 in the Gilan province (Iran), and she subsequently laid eggs on 29 May (4 eggs) and 5 July (4 ones). The eggs had length of 10.4–12.8 mm, the width of 6.1–6.5 mm, and the weight of 0.240–0.340 g. Young lizards came out from seven eggs after 52–55 days of incubation. The body length of these newborn lizards was 22.9–27.8 mm, the tail length was 38.5–46.5 mm, and the weight was 0.330–0.460 g.

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.

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.
