在1976年至1983年的6.5年间，对几内亚博苏的一小群野生黑猩猩的种群动态进行了研究。出生率（0.23胎/雌/年）较高，出生间隔（4.3-4.4年/雌）短于东非研究地点（贡贝和马哈尔国家公园）的黑猩猩。前3年的婴儿死亡率（0.06-0.18/年）低于东非。然而，人口自1967年以来几乎保持稳定（增长率：0.985/年）。出生数量的增加被青少年黑猩猩的消失（可能是移民）所抵消。成年男性移民和消失（也许移民），但成年女性很少这样做。
The population dynamics of a small group of wild chimpanzees at Bossou, Guinea, were studied during a 6.5-year period between 1976 and 1983. The natality rate (0.23 births/female/year) was higher and the interbirth interval (4.3–4.4 years/female) was shorter than those of chimpanzees at East African study sites (the Gombe and Mahale National Parks). The infant mortality for the first 3 years (0.06–0.18/year) was lower than those in East Africa. However, the population had remained almost stable since 1967 (growth rate: 0.985/year). The increase in number by births was offset by the disappearance (perhaps emigration) of adolescent chimpanzees. Adult males immigrated and disappeared (perhaps emigrated) but adult females rarely did.
