Body size variation of odorous frogs (Odorrana grahami) across altitudinal gradients.

The article discusses the study which determined the ages of 249 odorous frogs, Odorrana grahami, from four locations in Sichuan Province, China, with the use of skeletochronology. It found from excised toe bone for 242 individuals, distinct lines of arrested growth (LAGs), with each LAG assumed to represent one year of age. The study also revealed significant differences in average adult snout-vent length (SVL) and age among female populations, but not in males.
