skeletochronological method Rana omeimontis age structure sexual size dimorphism
We used skeletochronology to estimate age structure of the Omei Wood Frog, Rana omeimontis, from southwestern China. Average age differed significantly between males and females. Age at sexual maturity in both males and females was 1 year. Longevity was 6 and 7 years for males and females, respectively. Average body size differed significantly between the sexes, with females being larger than males. A non-significant correlation between age and body size was found within each sex in this population. The ANCOVA analysis revealed that females also had larger body size than males when the effect of age was controlled.
