Age, body size and clutch size are important demographic traits directly related to the life history strategy of a species, but little is known about these parameters in Rana kunyuensis, a frog endemic to China. In the present study, we investigated body size, age structure and clutch size of this species in a population from Mt. Kunyu. Age at maturity of males and females was 1 year and 2 years, respectively. The maximum age of males and females was 4 and 5 years, respectively. Females were significantly larger than males. Our results revealed a positive correlation between age and body size; however, body size was not a good indicator of age because there was an extensive overlap in body size among age classes. Clutch size was also positively correlated with body size. These data provide the first detailed life history information for Rana kunyuensis.
