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).

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.

The characteristic is given and the taxonomic structure of the modern bathrachological collection of the Zoological Museum of the Saratov National Research State University named after N. G. Chernyshevsky is analyzed. Currently, it has 1903 specimens of amphibians belonging to 46 species of 13 families. The Ranidae family is the most fully presented one (43.3% of the total number of storage units). In total, the Ranidae collection contains 711 specimens of 10 frog species, of which 2 species (569 specimens) account for Saratov regional collections.

The history of formation and the taxonomic composition of the salamander collection of the Zoological Museum of Tomsk State University, opened in 1888, are analyzed. The history of the collection is characterized by two periods of active formation, namely: late 19th – early 20th centuries and late 20th – early 21st centuries. It is associated with the names of prominent explorers of Siberia, namely: N. F. Kashchenko, S. I. Korzhinsky, A. A. Kulyabko, G. E. Ioganzen, M. D. Ruzsky, V. P. Anikin, and S. M. Chugunov.

Five species of amphibians and five species of reptiles are recommended to the inclusion into the third edition of the Red Data Book of Tambov region. Their conservation status, distribution, main limiting factors, adopted and necessary protection measures are discussed.

A comparative assessment of morphological features of erythrocytes Pelophylax ridibundus (Pallas, 1771) and Bufotes viridis (Laurenti, 1768) living near the territory sprayed with pesticides was carried out. Multidirectional changes in the parameters of erythrocytes in the compared species were revealed, expressed in an increase in the width, area and volume of cells in P. ridibundus and a decrease in the values of these parameters in B. viridis.

The results of the study of hematological parameters of the blood of the larvae caucasian brown frog Rana macrocnemis and the total activity of catalase compared with adults and at different temperature conditions: at 23°C and after five days of hypothermia at 5°C. Differences in the blood formula were revealed in different periods of ontogenesis and under the influence of artificial hypothermia.
