Atmospheric advection of heat or cold: The formation of the false spring phenomenon in the spawning migrations of anuran amphibians (Amphibia, Anura) in Europe

Authors: Yermokhin M. V., Tabachishin V. V., Tabachishin V. G.

The spawning migrations of four widespread species of anuran amphibians in European fauna (Pelobates vespertinus, Bombina bombina, Pelophylax ridibundus, and Rana dalmatina) were analyzed. In the years with an abnormally early start of the spawning migrations of the anuran amphibians and their passage through a false spring, powerful anticyclones over Central Asia, Trans-Urals or Western Siberia blocked the west–east atmospheric transfer.

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

Authors: Kuranova V. N., Yakovlev V. A.

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.

Seasonal activity and terms of the emergence of hatchlings in True lizards (Sauria: Lacertidae) of Karadag Nature Reserve in Crimea and their relationship with climatic parameters

Authors: Kukushkin O. V.

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.
