Demographic studies on translocated primate groups provide a unique opportunity to study population dynamics, social strategies, and reproductive parameters of a species adapting to new environments. In 1996, 38 Japanese macaques (Macaca fuscata) of the Minoo-H group (Osaka Prefecture, Japan) were translocated to Affenberg Landskron, a four-hectare naturally forested park in southern Austria. By January 2020, the population had increased to 160 individuals, and a total of 223 births were recorded. Births peaked in late April to late May, and the timing was influenced by neither offspring sex nor parity status of the mother. Infant mortality was low (8.97%), mostly involving primiparous females, and the average interbirth intervals were shorter following the death of an infant (1.10 years) than a surviving infant (1.77 years). Females rarely had offspring with the same males repeatedly, and the reproductive success among males declined with increasing years of presence in the group. The main aspects of reproduction, mortality, and mate choice are consistent with published data on natural and provisioned populations in Japan and those translocated to other countries. The life expectancy for females, however, was relatively high (11.72% chance of reaching the age of 20), whereas birth control prevented them from using their lifetime reproductive potential. By January 2020, the number of old individuals (> 18 years; 17.5%) was close to that of juveniles (< 4 years; 22.5%). The specific group composition, along with the inability of males to emigrate out of their natal group, may affect the social dynamics of the population, which merits further attention in future studies.

对易位灵长类群体的人口统计研究为研究适应新环境的物种的种群动态、社会策略和繁殖参数提供了独特的机会。 1996 年，38 只 Minoo-H 群（日本大阪县）的日本猕猴（ Macaca fuscata ）被转移到奥地利南部占地四公顷的自然森林公园 Affenberg Landskron。到 2020 年 1 月，人口已增至 160 人，总共出生 223 人。出生高峰期为四月下旬至五月下旬，出生时间不受后代性别和母亲产次状况的影响。婴儿死亡率较低（8.97%），主要涉及初产女性，婴儿死亡后的平均生育间隔（1.10 岁）比存活婴儿（1.77 岁）短。雌性很少与同一只雄性反复生育后代，而且雄性的繁殖成功率随着群体中存在时间的增加而下降。繁殖、死亡率和配偶选择的主要方面与日本和转移到其他国家的自然和供应种群的已发表数据一致。然而，女性的预期寿命相对较高（达到 20 岁的几率为 11.72%），而节育措施使她们无法发挥一生的生育潜力。到2020年1月，老年个体（> 18岁；17.5%）的数量接近青少年个体（< 4岁；22.5%）。特定的群体构成，以及男性无法移出其出生群体的能力，可能会影响人口的社会动态，这值得在未来的研究中进一步关注。
