Places, times and wintering conditions of the viviparous lizard Zootoca vivipara (Lichtenstein, 1823) (Sauria: Lacertidae) in Western Siberia

A number of aspects of the hibernation of the viviparous lizard (Zootoca vivipara) in the Asian part of its range are analyzed. The results of our own field work for the period from 1971 to 2022 in the Altai Republic (Altai Nature Reserve, Tomsk, Kemerovo, Chelyabinsk and Sverdlovsk regions are used). Within 17 localities of the foothill and flat parts of the south of Western Siberia (51°22΄ – 57°04΄ N, 57°33΄ – 88°08΄ E), 54 wintering sites were recorded. 173 li-zards of different sexes and ages were noted in the wintering shelters.

In the course of multi-year field research (2002–2022, and partially 2023) in the Karadag Nature Reserve (southeastern Crimea; 44.9º N, 35.2º E) the seasonal activity frame and terms of the emergence of juveniles were studied in two common species of lacertids: the Balkan wall lizard (Podarcis tauricus) and the Crimean rock lizard (Darevskia lindholmi). Activity during the winter period is characteristic for both species: over 22 years of observations, P. tauricus and D.
