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.

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.
