生物系统的稳定性需要进化的机制来促进稳健性。具有凝聚力的灵长类社会群体是稳定的生物系统的一个例子，尽管经常发生冲突，但这种系统仍然存在。任何生物系统都可能存在多个稳定来源，这种稳健性或缺乏这种稳健性应该得到反映，因此可以在群体的网络结构中检测到，而且可能在多个层面上。在这里，我们展示了网络结构和群体稳定性如何与群体中个体代理人的基本特征以及这些个体相互作用的环境和社会背景相联系。在非人类灵长类物种中，从个体水平到群体水平考虑了内部因素(如个性、性别)和外部因素(如等级动态、性别比)，以考察网络结构对群体稳定性的影响。结果产生了三个主要发现。首先，成功的第三方干预行为是猕猴群体稳定的一种机制，因为成功的干预会减少社会群体的伤害。其次，人格是决定哪些人扮演关键干预者角色的主要因素，它通过对社会权力和支配差异的影响而发挥作用。最后，拥有较高社会权力的个人不仅是关键的干预者，也是培养网络的关键参与者，并接受更多样化的个人的和解。这项研究的结果提供了可靠的证据，表明个性和性别比例等个人和群体特征影响着网络结构，如和解、梳理和冲突干预的模式，这些模式是恒河猴社会中网络健壮性和随后的健康和福祉的指标。利用这种网络方法为行为和社会过程如何影响非人类灵长类群体的社会稳定性提供了更好的洞察力。
Stability in biological systems requires evolved mechanisms that promote robustness. Cohesive primate social groups represent one example of a stable biological system, which persist in spite of frequent conflict. Multiple sources of stability likely exist for any biological system and such robustness, or lack thereof, should be reflected and thus detectable in the group's network structure, and likely at multiple levels. Here we show how network structure and group stability are linked to the fundamental characteristics of the individual agents in groups and to the environmental and social contexts in which these individuals interact. Both internal factors (e.g., personality, sex) and external factors (e.g., rank dynamics, sex ratio) were considered from the level of the individual to that of the group to examine the effects of network structure on group stability in a nonhuman primate species. The results yielded three main findings. First, successful third-party intervention behavior is a mechanism of group stability in rhesus macaques in that successful interventions resulted in less wounding in social groups. Second, personality is the primary factor that determines which individuals perform the role of key intervener, via its effect on social power and dominance discrepancy. Finally, individuals with high social power are not only key interveners but also key players in grooming networks and receive reconciliations from a higher diversity of individuals. The results from this study provide sound evidence that individual and group characteristics such as personality and sex ratio influence network structures such as patterns of reconciliation, grooming and conflict intervention that are indicators of network robustness and consequent health and well-being in rhesus macaque societies. Utilizing this network approach has provided greater insight into how behavioral and social processes influence social stability in nonhuman primate groups.
