Abstract:

During Oct, 2010 and Oct, 2012, we totally sampled 2346 individuals in the population of Rice frog Rana limnocharis in Ji’An, Jiangxi Province. Using the hierarchical clustering method, the age structure of the population was divided into six age-groups. We treated the group-age as a relative age of each individual, and then calculated the mean relative age of different individual flocks according to year and habitat. Results showed that the mean age of the population of rice frog has a regularly seasonal variation. Two breeding peaks occurred in each year, which leading to lower value of mean age in corresponding month. Foraging dispersal may be the causation of higher mean age value of individual flocks in dry lands.
