The book presents up-to-date information on all the species and subspecies of turtles (7 species), lizards (112 species) and snakes (74 species) inhabiting the territory of North Eurasia. The North Eurasia region is considered as former Soviet Union and Mongolia territories in accordance with the decision of IUCN Species Survival Commission (SSC) of June 2003. In this richly illustrated book, we tried to reflect the results of new taxonomic and phylogenetic revisions that have not previously been included in herpetological monographs published in Russian and referred to this region. Detailed geographic distribution information, with schematic maps, data on type localities and conservation status (IUCN and regional Red lists, Cites, Bern convention) are included in each species account. The present atlas can be used as illustrated reference manual of the reptiles of North Eurasia. The data provided could serve as a basis for Global Reptiles Assessment (GRA). More than 400 color illustrations are included in the atlas (photos of reptiles, habitats and maps).
