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.

AGE AND GROWTH OF THE EICHWALD’S TOAD (BUFO EICHWALDI LITVINCHUK, BORKIN, SKORINOV ET ROSANOV, 2008) IN THE LENKORAN LOWLAND (SOUTHEASTERN AZERBAIJAN)

Authors: Matushkina K. A., Yanchurevich O. V., Kidov A. A.

Data on the age and growth of the Talysh toad in the Lenkoran Lowland are provided from sceletochronological analysis. Females are larger than males by body size. The reproductive part of the population is mainly composed by animals aged 3 - 6 years. The maximum age of females and males in the studied group was 9 and 8 years, respectively. Males and females reach their sexual maturity after 1 - 2 and 3 winters, respectively.

AGE, BODY SIZES AND GROWTH OF ZOOTOCA VIVIPARA (SAURIA: LACERTIDAE) FROM ITS MOUNTAIN POPULATIONS IN THE KUZNETSK ALATAU (SOUTHEAST OF THE WESTERN SIBERIA)

Authors: Epova L. A., Kuranova V. N., Yartsev V. V., Absalyamova E. N.

The present paper studies Zootoca vivipara populations from the low, medium and alpine zones of the Kuznetsky Alatau. By using skeletonchronology, the age of animals was determined, and the life longev-ity, sex -age structure, growth rate of bone and body were estimated. Males and females had the highest growth rates of bone and body until their second wintering, and then they decreased. Slow-growing specimens reach older ages. The body length of males and females in different age classes overlaps, and the oldest individuals were not necessarily the biggest ones.
