Phylogeny and geographic distribution of rock lizards (Lacertidae, Reptilia) in Alborz mountain range

Authors: Iryshkov E. S., Solovyeva E. N., Arakelyan M. S., Rastegar-Poyani E., Moaddab M., Milto K. D., Galoyan E. A.

Rock lizards of the genus Darevskia have long been an important model object for study of reptile evolution. To understand the overall picture, it is important to know how bisexual and parthenogenetic species are distributed within this genus. The ranges of Caucasian species of rock lizards have been studied for a long time and in detail. However, recent attention to the species inhabiting the territory of Iran has been attracted after the description of several new species in 2013.

Authors: Lyapkov S. M.

With the help of artificial inter-population crosses of adult Rana temporaria from four spatially remote populations of the European part of the species' range, the magnitude and direction of changes in metamorphic traits were estimated.

Ecological niches breadth analysis of Darevskia (Lacertidae, Reptilia) parthenogenetic lizards with various scenarios of clonal lineage formation in populations

Authors: Osipov F. A., Bobrov V. V., Dergunova N. N., Arakelyan M. S., Petrosyan V. G.

In this work, we tested the conditions for fulfilling the concept of geographic parthenogenesis by a comparative analysis of the breadth of the ecological niches of parental and parthenogenetic lizards of the genus Darevskia with a various number of established hybridization events. Estimates of the breadth of ecological niches of the parthenogenetic species D. rostombekowi Nb = 0.6(±0.08) and parental bisexual species D.

Modelling the range dynamics of the marsh frog (Pelophylax ridibundus) (Ranidae, Amphibia) in Russia under alternative scenarios of global climate change

Authors: Petrosyan V. G., Osipov F. A., Bashinskiy I. V., Dergunova N. N., Bobrov V. V.

Predictive maps of the distribution of the marsh frog (Pelophylax ridibundus) in Russia under the conditions of global climate change up to 2100 are presented. It is shown that under the influence of global climate change, the range will expand and the centroid will shift to the north-east.

On the issue of sex differences in metric characters in Anguis colchica (Nordmann in Demidoff, 1840) (Anguidae, Reptilia)

Authors: Ryzhov M. K., Romanova E. B., Bakiev A. G.

The length of the body without a tail (L.) and the length of an intact tail (L. cd.) were measured in 91 males and 110 females of Anguis colchica from the Chamzinsky rayon of the Republic of Mordovia. A comparative analysis of three morphometric characters (L., L. cd., L. / L. cd.) of males and females was carried out with the construction of variation series and using the frequency approach. Range of variability of L. and L.

Histological and computed tomography study of osteoderm regeneration in the skink lizard Eurylepis taeniolata Blyth, 1854 (Scincidae, Squamata)

Authors: Cherepanov G. O., Gordeev D. A., Melnikov D. A., Ananjeva N. B.

Skink lizards have an unusual complex osteoderm, which consists of several bone elements – osteodermitis. We have carried out the first histological and computer microtomographic study of the structure of the original and regenerating complex osteoderms of skink lizards using Eurylepis taeniolata as an object. The topography of osteoderms in the integument of the original region of the tail and its regenerated part was studied. The fundamental similarity of the morphology and microstructure of the original and regenerated osteoderms was showed.

Authors: Voronin M. Y., Yermokhin M. V.

Abnormal activity of Pelophylax ridibundus in the cooling pond of the Balakovo NPS (Saratov region) was detected during the winter period of 2003. The temperature range within which this activity was observed corresponds to that for the exit of individuals of this species from wintering during the spring period.

Authors: Doronin I. V.

We describe a case of temporary transfer of a striated lizard, Lacerta strigata Eichwald, 1831 to eating winged individuals of the cornfield ant, Lasius alienus (Foerster, 1850) registered in the territory of the Staropavlovskaya village, Stavropol region.

ON THE COLORATION PATTERN OF NEWBORNS OF THE SAND LIZARD, LACERTA AGILIS LINNAEUS, 1758 FROM TWO POPULATIONS (SAMARA REGION)

Authors: Eplanova G. V.

The coloration pattern of 485 newborn sand lizards (Lacerta agilis Linnaeus, 1758) got by laboratory egg incubation was studied. The eggs were laid in terrariums by 109 pregnant females caught at two localities in the Samara Region (2011 - 2013 and 2015). The posterity of the females from the Togliatti locality exhibited two coloration morphs, typica exigua and immaculata-concolor, whereas that of the females from the Mordovo village (33 km from Togliatti, the opposite bank of the Volga river) had only one pattern, typica exigua.

NATURE PROTECTION STATUS OF AMPHIBIANS AND REPTILES IN SARATOV REGION

Authors: Shlyakhtin G. V., Tabachishin V. G., Yermokhin M. V.

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.

ON THE NUTRITION OF SOME SEMI-AQUATIC AMPHIBIAN SPECIES (AMPHIBIA: ANURA) IN THE NORTHWESTERN UPPER OKA REGION

Authors: Alekseev S. K., Korzikov V. A., Ruchin A. B.

The nutrition of Bombina bombina and Pelophylax lessonae collected in three habitats of the northwestern Upper Oka region in 2006 - 2014 was studied. The feed composition of Pelophylax lessonae reduced to the autumn by the abundance and taxonomic diversity, epigeious beetles and ants to predominate. Bombina bombina mainly feeds on ants and arachnids in the autumn.

A CASE OF SUCCESSFUL HUNTING OF A PARASTEATODA TEPIDARIORUM (C. L. KOCH, 1841) (ARANEAE: THERIDIIDAE) SPIDER FOR A PONTIC LIZARD DAREVSKIA PONTICA (LANTZ ET CYRÉN, 1919) (SAURIA: LACERTIDAE)

Authors: Doronin I. V., Garmasheva N. N.

The paper describes a first case of successful hunting of a Parasteatoda tepidariorum (C. L. Koch, 1841) spider for a juvenile individual of Pontic Lizard, Darevskia pontica (Lantz et Cyrén, 1919), recorded in the territory of Slavyansk-on-Kuban town (Krasnodar Region, Russia).

A SIMPLE METHOD FOR FEEDING STUDIES IN LIVE ANURAN AMPHIBIANS

Authors: Kuzmin S. L.

A simple method of food sampling in live frogs is described. This method enables complete extraction of the stomach contents and leads to a very low mortality of frogs. That is why it is more reasonable than killing and preserving frogs for further study of their diet composition. Photographs of food extracting are provided, which can be used in field conditions.

ON POSSIBLE ESTIVATION OF PHRYNOCEPHALUS HELIOSCOPUS (PALLAS, 1771) AND EREMIAS ARGUTA (PALLAS, 1773) IN THE ALTAI REGION

Authors: Krymov N. G.

Summer counts of Phrynocephalus helioscopus (Pallas, 1771) and Eremias arguta (Pallas, 1773) were conducted in the Altai Region during April - September, 2016. A sharp decline in the activity of lizards in June and July was noted, due to the high temperatures and dry weather. As a result of excavation of some burrows, lizards in a non-active state were found. The possibility of summer hibernation (estivation) of the species is considered.
