Data on the modern distribution of amphibians and reptiles within the administrative boundaries of Kazan City are presented. The habitats of 11 species of amphibians and 4 species of reptiles have been preserved within the city. The main trends in changes in the species composition of herpetofauna from the end of the 20^th century to the present are presented. The prospects for the conservation of all species in the context of the current development of the territory of Kazan City are considered.

The paper presents a comparative analysis of the growth rates and characteristics of 10 lizard species from the genus Darevskia (D. armeniaca, D. arribasi, D. brauneri, D. caucasica, D. daghestanica, D. derjugini, D. mixta, D. pontica, D. raddei, and D. valentini) in laboratory conditions. It has been shown that lizards from different species complexes, but originating from close localities, are characterized by similar growth features.

Field research was conducted on the Kerzhensky Nature Reserve territory (the Nizhny Novgorod region, Russia) in 2012-2013 to analyze the influence of the 2010 forest wildfires on the populations of amphibians and reptiles and to reveal features of their post-wildfire recovery. The recovery of the herpetocomplexes on the territories subjected to surface/crawling and controlled fires was found to occur during no more than two years, whereas crown/canopy fires with complete vegetation destruction required three years for recovery.

An overview of the cases of introduction (both accidental and intentional) of amphibians and reptiles in the Caucasus and Crimea is provided. The introduction cases are systemized in accordance with the goals and ways of introduction and with regards to the expected scale of the impact and its nature. No negative consequences of the introduction of amphibian and reptile species in the Crimea and Caucasus are currently observed on any of the known examples.

On the basis of modern field surveys, collection data, and analysis of the literature data, a list of amphibian and reptile species recommended for inclusion into the 3rd edition of the Red Book of the Saratov Region was compiled. It contains 7 species of the batrachofauna and herpetofauna of the region, belonging to 3 groups, 5 families, and 6 genera. We offer to add 1 new species into the Book and to exclude 1 species, and there appeared prerequisites for revision of the existing protection status of 2 taxa.

An annotated list of amphibian and reptile species of the Russian Far East is presented with due account of modern data on the taxa systematics. 13 Amphibian species and 27 reptile ones have been reliably registered by now, including several random sea species.

The author has collected and integrated records on 7 amphibian species and 9 reptile ones in the Evreiskaya Autonomous Oblast’ (Russian Federation). Most of these species are found to be distributed in the mountain-forest area of the region, which is due to a combination of several factors (temperature limits, the availability of refuges, and food base).

When studying the late Cenozoic history of amphibians and reptiles, a number of problems arise, associated with obtaining and interpretation of factual material. First of all, the author considers peculiarities of obtaining and identifying fossil material, which strongly affects the amount and quality of paleontological data. Most biologists are not familiar with them. These are problems of taphonomy, demand, economy, personnel, collection and systematic problems.

New data on the distribution of 10 amphibian and 6 reptile species in the Vladimir Region is given. The list of species contains 198 new records including such rare species as Bombina bombina and Coronella austriaca.
