山海关（Mandrillus sphinx）是神秘的旧世界灵长类动物，其社会组织和生态仍然知之甚少。例如，以前的研究表明，群体只由成年雌性和它们的幼崽组成，或者由一个成年雄性和几个雌性组成的几个单位构成更大的永久社会单位。在这里，我们提出了第一组的组成和男性范围模式的数据，从唯一习惯的野生山海关集团和研究如何家庭范围的大小和每日路径长度变化与环境和人口因素超过15个月的时间。我们的研究地点位于加蓬南部，在那里我们每天跟踪该组，收集有关其个体成员的存在，范围，行为和寄生虫负荷的数据。在整个研究过程中，该组由大约120个个体组成，包括几个非出生和纳塔尔的成年和亚成年雄性。从未观察到单雄性单位。山鸡行进估计0.44-6.50公里/天，在866.7公顷的家庭范围内。探索性分析表明，降水量，成年男性的数量，以及原生动物寄生虫的丰富度都与每日路径长度呈正相关。这些结果澄清了社会系统的山鸡，并提供了第一次深入了解的因素，塑造他们的测距模式。(C)2015 Wiley Periodicals，Inc.
Mandrills (Mandrillus sphinx) are enigmatic Old World primates whose social organization and ecology remain poorly known. Previous studies indicated, for example, that groups are composed of only adult females and their young or that several units composed of one adult male and several females make up larger permanent social units. Here, we present the first data on group composition and male ranging patterns from the only habituated wild mandrill group and examine how home range size and daily path length varied with environmental and demographic factors over a 15-month period. Our study site is located in southern Gabon where we followed the group on a daily basis, collecting data on presence, ranging, behavior, and parasite load of its individual members. Throughout the study, the group was made up of about 120 individuals, including several non-natal and natal adult and sub-adult males. One-male units were never observed. The mandrills traveled an estimated 0.44-6.50 km/day in a home range area of 866.7 ha. Exploratory analyses revealed that precipitation, the number of adult males present, and the richness of protozoan parasites were all positively correlated with daily path length. These results clarify the social system of mandrills and provide first insights into the factors that shape their ranging patterns. (C) 2015 Wiley Periodicals, Inc.
