We examined life-history traits such as population age structure, growth and longevity of Iranian Long-Legged frogs (Rana macrocnemis) from 4 different locations at different altitudes in Turkey by skeletochronology performed on the phalanges. The maximum lifespan was 5 years in Macka (350 m a.s.l.), 6 years in Hidirnebi (1430 m a.s.l.), 8 years in Sarikamis (2276 m a.s.l.) and 10 years in Ovit (2850 m a.s.l.). Age at sexual maturity of both males and females was 2-3 years in the Macka, Hidirnebi and Sarikamis populations, while 3-4 years for males and 3-5 years for females in the Ovit population. In all populations, males and females did not exhibit any differences in terms of mean age and SVL except for Sarikami, s where the males were significantly larger than the females. A positive correlation was observed between age and SVL for both sexes in all populations except for the males of the Macka population.
