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).

The paper presents data on the variability of basic morphological characters of the sand lizard (Lacerta agilis) inhabiting the vicinities of the cities Tyumen (Western Siberia) and Sterlitamak (Southern Urals). Five subtypes of back coloration were identified. Typical and atypical variants of the coloration pattern are described. A high level of the genetic variability of the ISSR markers of sand lizards was revealed. It was significantly lower in the group of mature individuals as compared to juveniles.

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.

The adder is a usual, locally-numerous species, occurring sporadically in most parts of the Vladimir Region: everywhere in the Meshchersky Lowland and Prinerlinski District, sporadically on the Kovrovsko-Kasimovskoe Plateau, Klin-Dmitrov Ridge, in the Opole. The largest adder populations are in Yuryev-Polsky District. The adder occurrence in different habitats varies from 0.01 to 1.33 individuals per 1 km route. The maximum adder occurrence is in Kovrov (1.33 ind. / km) Vyaznikovsky (0.83 ind. / km) and Kameshkovski (0.44 ind. / km) Districts.

The reproductive structure of Cosmocerca ornata (Dujardin, 1845) in marsh frogs (Pelophylax ridibundus (Pallas, 1771)) of both the striata and non-striata phenotypes was studied. Distinctions in the physiology, ecology and behavior of striped and unstriped amphibians have certain influence on the intensity of processes of the host infestation and maturing of C. ornata in frogs of different phenotypes. Analysis of the age structure of the C.

During the field season of 2014, research was conducted on 5 areas planned for organizing protected areas in Kazan City. The examined areas were found to be important for preserving the diversity of amphibians and reptiles in the city. Of major concern is preservation of the northern crested newt (Triturus cristatus Laurenti, 1768) and the common toad (Bufo bufo, Linnaeus, 1758) in those territories, the species listed in The Red Data Book of the Republic of Tatarstan.

The paper considers qualitative and quantitative characteristics of pholidosis variations in two lizard species, comparative analysis of these indices at both intraspecific and interspecific level is carried out. 45 and 19 types of deviations were observed in the sand lizard and common lizard respectively. Variations of the labial, supraocular and supraciliar, frontonasal, parietal, occipital and ventral scales are more common in both species. The sand lizards from the Spassky region differ from the others by some indices.

Terrestrial route counts of reptiles in 24 localities of the plateau Ustyurt were carried out in 2007 - 2008. 474 individuals of 15 species were found along a total of 243.5 km passed. Based on the results of our survey, the reptile population structure has been clarified in 12 landscapes. The low specific diversity and population density of reptiles were observed everywhere. 2 to 8 species with a population density of 1.9 - 8.4 individuals per ha were found in certain landscapes. In terms of abundance, the reptiles belonged to rare or common species.

Novel data on the distribution, habitats and population density of the Crimean (Balkan) wall lizard, Podarcis tauricus (Pallas, 1814) in the Odessa Province of the Ukraine are given. For the majority of the localities known from the literature data in the Pre-Danube Region, the current dwelling of the species was confirmed, and its population density over limited areas remains quite high, namely: from 5–10 to 70–100 specimens/1000 sq. m. The northernmost point of the P.
