乍一看，我们似乎已经知道很多关于人口统计学事件，如出生，死亡和运动如何影响动物社会网络结构。毕竟，种群动态是动物生态学中研究得很好的一个方面，并且人们对动物社交网络的经验和理论兴趣越来越大。然而，正如静香和约翰逊（2019）所证明的那样，我们对这两个领域交叉点的问题的认识实际上还处于起步阶段。随着人类导致的死亡率持续上升，了解动物社交网络如何应对人口统计学事件变得越来越重要（Busson et al. 2019）。从阅读Shizuka和约翰逊的刺激性评论中可以清楚地看到，预测网络在出生、死亡和运动后是否以及如何发生变化绝非易事。多种因素可以影响人口统计数据是否具有网络范围和长期的影响。例如，不同类型的整合流程和周转事件可能各自导致不同的结果（Shizuka and约翰逊，2019）。回顾中提到的一个影响因素值得强调，那就是个人行为差异在推动人口统计学事件如何塑造网络方面所发挥的作用。在更大的范围内，物种差异不仅会影响出生、死亡和迁徙的速度，还会影响动物在这些事件发生后是否以及如何调整它们的社会关系。例如，生活在裂变融合群体中的个人通常比生活在稳定群体中的个人经历更动态的社会环境，因此可能更有可能以允许网络补偿节点损失或引入的方式做出反应。因此，在某些网络中，人口统计事件可能不会产生长期和广泛的影响。
At first glance, it would seem that we already know a lot about how demographic events such as birth, death, and movement influence animal social network structure. After all, population dynamics is a well-studied aspect of animal ecology, and there is increasing empirical and theoretical interest in animal social networks. However, as Shizuka and Johnson (2019) demonstrate, our knowledge of the issues at the intersection of these two fields is actually at infancy. As human-induced mortality rates continue to rise, understanding how animal social networks respond to demographic events is becoming increasingly important (Busson et al. 2019).It is clear from reading Shizuka and Johnson’s stimulating review that predicting if and how networks change after birth, death, and movement is far from trivial. Multiple factors can influence whether demographics have network-wide and long-lasting consequences. For example, different types of integration processes and turnover events can each lead to different outcomes (Shizuka and Johnson 2019). One influential factor that has been mentioned in the review and deserves emphasis is the role that individual behavioral differences play in driving how demographic events shape networks. At a larger scale, species differences can influence not only the rate at which births, deaths, and movement occurs but also if and how animals adjust their social connections after these events. For instance, individuals living in fission–fusion groups usually experience a more dynamic social environment than those living in stable groups and, thus, might be more likely to respond in a way that allows the network to compensate for node losses or introductions. Consequently, demographic events might not have long-lasting and wide-spread consequences in some networks.
