Abstract

Observations of a translocated population of toad-headed agamas (Phrynocephalus guttatus) in the south of the Kalmyk Republic (1998–2001) have shown that seasonal differences in animal survival are manifested only in juveniles and the survival rate of juveniles is higher than that of adult individuals. A significant correlation between survival rate and sex is also characteristic only of juveniles: survival rate is higher in females than in males. In adult males, survival positively correlates with the level of activity; in juvenile males, with body size. In adult females, survival inversely correlates with body size and weight.
