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

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.
