1.Social behavior and reproductive parameters of free-ranging senile Japanese macaques (Macaca fuscata at Takasakiyama) and West African chimpanzees (Pan troglodytes verus at Bossou, Guinea) have been studied. Activity of senile female macaque goes down but her sociality doesn't decrease because daughters and other younger females aproach to groom her. Reproductive rate gradually decreases but lasts util 22-3 years old and suddenly drops. Females still survive another 4 or 5 years. Activity of senile female chimpanzee of more than 40 years old doesn't look change but she travels mostly with her family group and rarely does alone. Reproductive rate slightly decreases after 35 years old but lasts over 40.

1.自由放映的日本猕猴（Takasakiyama的Macaca fuscata）和西非黑猩猩（几内亚Bossou）的西非黑猩猩（几内亚bossou）的社会行为和生殖参数。老年女性猕猴的活动降低了，但她的社会性并没有减少，因为女儿和其他年轻的女性剥夺了她。生殖速率逐渐降低，但持续22-3岁，突然下降。女性仍然可以再生4到5年。 40岁以上的老年女黑猩猩的活动看起来并没有变化，但她主要与家庭团体一起旅行，很少独自一人。生殖率在35岁后略有下降，但持续40多个。
