这是第一次报告内的一个男性组的长鼻猴（Nasalis larvatus）的基础上详细识别的个人之间的关系。从2005年5月至2006年，焦点和自由数据的激动和理毛行为收集在森林沿着Menanggul河，沙巴，马来西亚。在研究期间，我们收集了超过1，968小时的成年男性焦点数据和1，539小时的6名女性焦点数据。它们的社会互动，包括争斗和梳理行为，似乎遵循其他colobines报道的典型模式：群体内社会互动的发生率很低。在39起争斗事件中，26起是从沿着睡觉的地方转移，6起是α雄性威胁其他猴子调解雌性之间和雌性与幼猴之间的争吵，7起是从喂食的地方转移。虽然基于33个组内激动事件（不包括成年人和青少年之间以及成年人和婴儿之间的事件）的激动行为矩阵指示非显著线性，但长鼻猴组内存在一些特定的主导个体。然而，梳理行为成年女性在一个群体中不受统治地位的等级。本研究还对长鼻猴和其他灵长类物种的梳理模式进行了初步比较。在梳理网络比较的基础上，发现性别分散型和雌雄分散型物种的梳理模式相似。由于这些物种中的成年雌性反复迁移到群体中，因此可能很难为群体中的特定个体建立牢固的梳理交换关系，这与雌性-philopatric/雄性-分散物种不同。然而，梳理灵长类物种之间的群体内的分布模式很难单独解释的基础上，他们的传播模式。在一些物种中，包括长鼻猴在内的新移民雌性渴望与高级群体成员进行社会互动，以提高其社会地位。
This is the first report on inter-individual relationships within a one-male group of proboscis monkeys (Nasalis larvatus) based on detailed identification of individuals. From May 2005 to 2006, focal and ad libitum data of agonistic and grooming behaviour were collected in a forest along the Menanggul River, Sabah, Malaysia. During the study period, we collected over 1,968 h of focal data on the adult male and 1,539 h of focal data on the six females. Their social interactions, including agonistic and grooming behaviour, appeared to follow typical patterns reported for other colobines: the incidence of social interaction within groups is low. Of 39 agonistic events, 26 were displacement from sleeping places along the river, 6 were the α male threatening other monkeys to mediate quarrels between females and between females and juveniles, and 7 were displacement from feeding places. Although the agonistic behaviour matrix based on the 33 intra-group agonistic events (excluding events between adults and juveniles and between adults and infants) was indicative of non-significant linearity, there were some specific dominated individuals within the group of proboscis monkeys. Nonetheless, grooming behaviour among adult females within a group were not affected by the dominance hierarchy. This study also conducted initial comparisons of grooming patterns among proboscis monkeys and other primate species. On the basis of comparison of their grooming networks, similar grooming patterns among both-sex-disperse and male-philopatric/female-disperse species were detected. Because adult females in these species migrate to groups repeatedly, it may be difficult to establish the firm grooming exchange relationship for particular individuals within groups, unlike in female-philopatric/male-disperse species. However, grooming distribution patterns within groups among primate species were difficult to explain solely on the basis of their dispersal patterns. Newly immigrated females in some species including proboscis monkeys are eager to have social interactions with senior group members to improve their social position.
