One of the negative impacts of climate change is the emergence of alien invasive species. As such,
numerous alien lizard species recently appeared in Eastern Europe, such as in Ukraine: Podarcis muralis,
Darevskia armeniaca, D. dahli, Tenuidactylus bogdanovi (breeding), representatives of Hemidactylus
(chance find), as well as in Latvia: Scinax ruber, Podarcis siculus, Podarcis ionicus (chance find). This is
not an exhaustive list. By implementing bioclimatic modeling approach based on GIS modeling (Maxent,
WordClim), we demonstrate that in the near future (by 2050) new species from neighboring countries
may appear - D. praticola (in the Danube basin and the Carpathians) and Ablepharus kitaibelii (in the
Danube basin). The most promising species that are expected to expand their range and appear in the
Baltic countries in the near future are P. muralis, D. praticola, A. kitaibelii and P. siculus. For these
species, the range is predicted to expand by more than 1.2 times. As for geckos, they are confined to
urban buildings or ruins, where there is sufficient solar insolation and microclimate. In Eastern Europe,
such gecko-habitats depend on man-made areas (excluding southern areas with natural rocky habitats).
Therefore, alien reptile species can be divided into 3 groups - eurybiont, future-promising and
synanthropic. We thank for their support the projects EMYS-R https://emysr.cnrs.fr, 16LW015, PAUSE
