amphibians

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 European common spadefoot, Pelobates fuscus, has not been observed in Moscow since the end of the 20th century. The species is listed in the Red Data Book of Moscow (2017) as endangered or completely extinct. The paper presents new findings of P. fuscus on the territory of the city, namely, in the “Moskvoretskiy” Natural-Historical Park and the “Kosinskiy” Natural-Historical Park in August 2020.

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.

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.

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.
