Abstract

The article provides data on the age structure and sexual dimorphism of the Far Eastern toad (Bufo sachalinensis) inhabiting the territory of the Ussurisky Nature Reserve. In total, preparations from 53 animals (22 females and 31 males) were studied. The age of the studied females ranged from 4 to 7 years, on average 5.2±0.97, males — from 2 to 6 years, on average 3.9±1.00. The average body length of females statistically significantly exceeded the body length of males. Besides, the study identified additional growth arrest lines common for summer periods. To conclude, the study did not find a positive correlation between age and body size.
