Age structure and growth of the oriental tree frog (Hyla orientalis, Amphibia, Hylidae) in the Samur Forest (North-Eastern Caucasus)

Authors: Kidov A. A., Ivolga R. A., Kondratova T. E., Ivanov A. A., Mazanaeva L. F., Askenderov A. D.

The paper presents the results of studying the age structure and growth of the eastern tree frog (Hyla orientalis) in the Samur Forest. In the Primorskiy village (Magaramkent district, Republic of Dagestan, Russian Federation) in the first decade of May 2022, 7 females and 13 males were captured. The age of animals was determined by the cross sections of phalanx by standard method of skeletochronology. Age of females was 2–5 years (3.4 on average), males 1–6 years (3.4 on average).

Rare species of amphibians and reptiles – candidates for the inclusion into the third edition of the Red Data Book of Tambov region

Authors: Lada G. A., Sokolov A. S., Goncharov A. G.

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.

Distribution of the smooth snake (Coronella austriaca austriaca Laurenti, 1768) (Colubridae, Reptilia) in the Caspian lowland of Russia and Kazakhstan

Authors: Mazanaeva L. F., Orlova V. F., Shepelya E. Y.

The distribution of smooth snake in the Caspian lowland of Russia and Kazakhstan is analyzed according to the collections of the Zoological Museum of Moscow State University and published works. The map with smooth snake finds includes 36 localities of the species (Volgograd Region, Stavropol Territory, Kalmykia, Chechen Republic, Dagestan, and Kazakhstan).

Comparative analysis of the growth and development of male and female Pevtsov's toad, Bufotes pewzowi (Amphibia: Anura, Bufonidae) in laboratory conditions

Authors: Matushkina K. A., Astakhova E. A.

Differences in growth rates are shown, as well as in the cost of rearing male and female Bufotes pewzowi under laboratory conditions. We observed a tendency for females to be superior in length and weight, but statistically significant differences (U = 13, p < 0.05) were noted only in weight after 50 weeks of rearing. Over the entire period of the study, the weight gain of females was 54.2±5.04 g, males – 45.3±6.15 g. The actual cost of rearing 1 female was 497.2±58.34 rubles (426.6–557.7), 1 male – 389.9±75.86 rubles (244.7–488.2).

Foster’s or island rule in populations of Phrynocephalus mystaceus and Eremias velox (Reptilia, Lacertilia) on the sandy massif Sarykum

Authors: Polynova G. V., Polynova O. E.

The sandy massif Sarykum, whose age is about 100 thousand years, is an island habitat for psammophilic species of terrestrial vertebrates. The paper presents new morphometric data on the populations of two species of psammophilous lizards living in this area. These are the nominative subspecies of the Secret Toadheaded Agama (Phrynocephalus mystaceus mystaceus Pallas, 1776) and the Caucasian Central Asian Racerunner (Eremias velox caucasica Lantz, 1928).

Thermobiological characters of toad-headed agamas (Phrynocephalus mystaceus) (Reptilia, Agamidae) on the Sarykum dune (Dagestan, Russia) obtained by using of temperature loggers

Authors: Cherlin V. A., Okstein I. L., Aligadzhiev E.

The paper compares two variants of thermobiological studies of toad-headed agamas (Phrynocephalus mystaceus) – the traditional one, based on route trapping and measurements of body temperature in captured lizards, and the new one, using temperature loggers that register body temperature once a minute and implemented interperitoneally. Both work options are not alternative. The main thing is the correct interpretation of the results: the traditional method provides data obtained from many individuals characterizing the temperature parameters of the activity of the studied reptiles.

Some features of thermobiology of steppe-runner Eremias arguta (Gmelin, 1789) and spotted toadhead agama Phrynocephalus guttatus (Gmelin, 1789) (Squamata, Reptilia) in cohabitation in the Northern Pre-Caspian

Authors: Chetanov N. A., Litvinov N. A., Ganshchuk S. V., Yugov M. V.

The paper presents data on temperatures of the body and the selected substrate for the steppe-runner and the spotted toadhead agama. Thermal preferences and modal classes for both species were determined, and interspecies differences were analyzed. Significantly higher average temperatures were found in the steppe-runner, while the maximum voluntary temperatures are higher in the spotted toadhead agama. These features are associated with the biotopic confinement of species.
