Captive breeding of Regel’s racerunner (Eremias regeli, Reptilia, Lacertidae)

Authors: Kidov A. A., Erashkin V. O., Ivanov A. A., Kondratova T. E.

The paper presents the results of laboratory reproduction of Regel’s racerunner (Eremias regeli). Offspring was obtained from natural individuals (2 females and 2 males) captured in the vicinity of the Bokhtar town (Khatlon region, Republic of Tajikistan). Captive-born animals (3 females and 2 males) began laying eggs at the age of 7 months. The lizards from nature reproduced twice a year, while the animals obtained in the laboratory lay eggs up to three times per season. The clutches of both natural and laboratory lizards contained from 2 to 4 eggs.

Captive breeding of the Caspian lizard (Darevskia caspica) (Reptilia, Lacertidae)

Authors: Kidov A. A., Ivanov A. A., Erashkin V. O., Kondratova T. E.

The Caspian lizard (Darevskia caspica) is a recently described endemic of the Hyrcanian forests of Northern Iran. The paper presents new data on the reproductive biology of D. caspica obtained in laboratory conditions. Breeding females have a body length of 53.4– 64.4 mm and a mass of 2.96–3.60 g. Females produce from one to three clutches per season, each of which contains 1–6 eggs. The length of these eggs is 10.35–13.95 mm, width 6.19–7.59 mm, and weight 0.27–0.45 g.

Male Reproductive Cycle in a Population of the Common Lizard Zootoca vivipara (Squamata, Lacertidae) from Southeast of Western Siberia

Authors: Yartsev V. V., Kuranova V. N., Absalyamova E. N.

Widely distributed reptile species are characterized by reproductive plasticity, which may also appear as variations of the reproductive cycles. To understand the specificity of the male reproductive cycle of Zootoca vivipara in the Asian part of its range, males from the Tomsk population (the southeast of the Western Siberia) caught from April till July 2017 were studied (n = 27).
