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).

Growth, Survival and Live Feed Utilization Efficiency of the Hyrcanian Meadow Lizard, Darevskia praticola hyrcanica (Lacertidae, Reptilia) in Captivity

Authors: Kidov A. A.

The paper presents materials on growing and winter hibernation of the Hyrcanian meadow lizard, Darevskia praticola hyrcanica, in artificial conditions. Juveniles were obtained from the captive breeding of lizards caught on the typical locality of this subspecies (Gadazyghahi Natural Boundary, the Talysh Mountains, Astara District, Azerbaijan) in the first decade of May, 2016. Immediately after leaving the eggs, newborn lizards were placed in groups of 5 specimens each into plastic 39×28×28 cm containers. Six groups were formed in total, and our research involved 30 lizards.

Growing of Larvae of the Caucasian Smooth Newt, Lissotriton lantzi (Wolterstorff, 1914) (Amphibia, Caudata) at Various Temperatures

Authors: Nemyko E. A., Vyatkin Y. A., Kidov A. A.

Lantz’s newt, or the Caucasian smooth newt, Lissotriton lantzi, is an endemic species of Caucasian forests. It was included in the Red Data Books of the Russian Federation and Republic of Azerbaijan. The design of a technology for keeping and reproducing this species in captivity will help its conservation. The paper discusses the results of larval growing of Lantz's newt at several temperatures. Newts were obtained from reproduction in artificial conditions.

Captive Breeding of the Alpine Newt, Ichthyosaura alpestris (Laurenti, 1768) (Amphibia, Caudata, Salamndridae) under Hormonal Stimulation

Authors: Kidov A. A., Nemyko E. A.

The Alpine newt, Ichthyosaura alpestris, is widely distributed in Central Europe. This species is common for most part of its habitat. I. alpestris is rare in Ukraine, Hungary, Bulgaria, Austria and Denmark. In the Netherlands, Belgium and Luxembourg the Alpine newt is endangered. A large number of publications on the keeping and breeding of this species in captivity is known. This allows the Alpine newt to be saved in artificial conditions, as well as to carry out projects on its reintroduction.
