变革是所有社会制度的根本。时间动态对于理解关系如何随着时间的推移而形成和变化至关重要，但很少在动物群体中明确研究。社会网络的方法是有用的，在描述协会模式，并提供有前途的工具，调查社会结构的变化的动态，但很少被用来量化动物协会如何随着时间的推移而变化。在这项研究中，我们描述和测试的时间分析框架的社会结构。我们提出了一个分析框架的方法，整合了社会规模和比较分析的变化，在社会结构中的多种类型的社会协会。这些方法允许在大小不同的组中进行比较，并且灵活地允许应用于加权和非加权网络，其中关系可以是有向的或无向的，并且关系可以是对称的或不对称的。我们应用这个分析框架，时间的社会网络数据从实验形成的圈养群体的和尚长尾小鹦鹉，Myiopsitta monachus，既评估我们的分析方法，并描述这个物种的社会结构。我们比较了动态的二元网络形成，自我网络形成和全球网络稳定模式的中立，亲和和竞争协会。我们发现，圈养和尚鹦鹉的社会结构形成和稳定在一个很短的时间内，但模式不同的社会协会类型。我们还发现了证据的一致性，在时间动态的形成和稳定的社会结构之间复制的社会群体。我们的分析方法成功地确定了社会结构的变化，这与定性观察相一致。这个框架可能是有用的，在各种各样的社会系统和物种的纵向数据的特征模式的时间动态的社会结构。(C)2012年，动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
Change is fundamental to all social systems. Temporal dynamics are critical in understanding how relationships form and change over time but rarely are studied explicitly in animal groups. Social network approaches are useful in describing association patterns and provide promising tools for investigating the dynamics of change in social structure but have rarely been used to quantify how animal associations change over time. In this study, we describe and test a framework for temporal analysis of social structure. We propose an analytical framework of methods that integrates across social scales and comparatively analyses change in social structure across multiple types of social association. These methods enable comparisons in groups that differ in size and are flexible to allow application to weighted and unweighted networks, where ties can be directed or undirected, and relationships can be symmetric or asymmetric. We apply this analytical framework to temporal social network data from experimentally formed captive groups of monk parakeets, Myiopsitta monachus, to both evaluate our analysis methods and characterize the social structure of this species. We compared dynamics of dyadic network formation, ego network formation and global network stabilization patterns across neutral, affiliative and agonistic associations. We found that social structure of captive monk parakeets formed and stabilized over a short period, but patterns differed by social association type. We also found evidence for consistency in the temporal dynamics of formation and stabilization of social structure between replicate social groups. Our analysis methods successfully identified change in social structure that corresponded well with qualitative observations. This framework is likely to be useful in characterizing patterns of temporal dynamics in social structure in longitudinal data in wide variety of social systems and species.
