This study applied a temporal social network analysis model to describe three affiliative social networks (allogrooming, sleep in contact, and triadic interaction) in a non-human primate species, Macaca sylvanus. Three main social mechanisms were examined to determine interactional patterns among group members, namely preferential attachment (i.e., highly connected individuals are more likely to form new connections), triadic closure (new connections occur via previous close connections), and homophily (individuals interact preferably with others with similar attributes). Preferential attachment was only observed for triadic interaction network. Triadic closure was significant in allogrooming and triadic interaction networks. Finally, gender homophily was seasonal for allogrooming and sleep in contact networks, and observed in each period for triadic interaction network. These individual based behaviors are based on individual reactions, and their analysis can shed light on the formation of the affiliative networks determining ultimate coalition networks, and how these networks may evolve over time. A focus on individual behaviors is necessary for a global interactional approach to understanding social behavior rules and strategies. When combined, these social processes could make animal social networks more resilient, thus enabling them to face drastic environmental changes. This is the first study to pinpoint some of the processes underlying the formation of a social structure in a non-human primate species, and identify common mechanisms with humans. The approach used in this study provides an ideal tool for further research seeking to answer long-standing questions about social network dynamics.

本研究应用社会网络分析模型描述了叟猴的三种亲和行为(理毛,休息,互动)的社会网络关系。本文章主要通过三种社会机制分析群内成员之间的互动模式,包括优先接近(即中心个体更容易形成新的连接),三角关系(以往密切联系会引发新的关系)和同质性(相似属性的个体容易互动)。与传统的个体间互动研究不同,本研究通过整体网络关系,分析了亲和社会网络的形成,以及这些社会关系的动态变化。这种整体观对理解社会行为规律和适应策略非常重要。动态分析有助于理解动物社会网络的弹性变化,理解其对剧烈环境变化的适应性。本研究开创性地分析了非人灵长类的亲和关系的社会结构网络的形成机制,并有利于理解人类的相似机制。本研究为理解学者长期关注的社会网络动态变化提供了一个理想的方法论。

Abstract: Pristine habitats have generally been expounded to be the most important ecological resources for wildlife conservation, but due to forest degradation caused by human activities, mosaics of secondary forests have become increasingly prominent. We studied three forest types in a mosaic tropical forest consisting of short secondary forest (SS), tall secondary forest (TS) and freshwater swamp forest (SF). These forests differed in stand structure and floristic composition; as well as phenological productivity of fruits, flowers and young leaves. We examined habitat use of long-tailed macaques (M. fascicularis) in relation to indices of phenological activity. The macaques used the SS for feeding/foraging more than the TS and the SF. This was because the SS had higher productivity of fruits which is a preferred food resource for macaques. Stem densities of young leaves in the SS and the TS also influenced habitat use, as they provided more clumped resources. Use of SF was limited but these forests provided more species rich resources. Our results showed that M. fascicularis responded to small-scaled variability in phenological activity between forest types found in a heterogeneous mosaic forest; with young secondary regrowth forests likely providing the most important food resources. Mosaic landscapes may also be important for other mammalian herbivores as they can buffer the effects of temporal food resource variability in any given forest type. In our increasingly human-altered landscapes, a better understanding of the role of secondary forest mosaics is crucial to the conservation and management of wildlife habitats and the animals they support.

摘要: 虽然原始生境被普遍认为是保护野生动物最重要的生态资源,但由于人类活动造成的森林退化,次生林的马赛克化破碎现象日益突出。我们研究比较了食蟹猴对三种的热带森林类型的生境利用,即矮林型次生林(SS)、高林型次生林(TS)和沼泽森林型(SF)。这些森林的林分结构和区系组成不同,而且果实、花朵和嫩叶的物候生产力也不同。我们分析了习惯化食蟹猴群的栖息地利用与物候指数关系。食蟹猴更倾向于在矮林型次生林取食。这可能因为矮林型次生林具有较高的果实产量,这些是猕猴的首选食物来源。矮林型次生林和高林型次生林内嫩叶也是是猕猴较集中的食物来源,嫩叶密度也明显影响猴群的栖息地利用。虽然沼泽森林型有更多的物种丰富度,但是猴群较少使用该类型森林。我们的研究结果表明,食蟹猴对不同类型的破碎化森林有着不同的适应。新形成的次生林可能为猴群提供了最重要的食物资源。实际上,破碎的森林景观对其他的草食性哺乳动物也很重要,因为它们可以缓冲任何既定类型森林内的食物资源短缺等变化对动物的影响。尤其在人类影响日益严重的森林景观中,进一步了解破碎化次生林对于野生动物保护和管理工作具有至关重要的意义。
