The development of multilayer network techniques is a boon for researchers who wish to understand how different interaction layers might influence each other, and how these in turn might influence group dynamics. Here, we investigate how integration between male and female grooming and aggression interaction networks influences male power trajectories in vervet monkeys Chlorocebus pygerythrus. Our previous analyses of this phenomenon used a monolayer approach, and our aim here is to extend these analyses using a dynamic multilayer approach. To do so, we constructed a temporal series of male and female interaction layers. We then used a multivariate multilevel autoregression model to compare cross-lagged associations between a male’s centrality in the female grooming layer and changes in male Elo ratings. Our results confirmed our original findings: changes in male centrality within the female grooming network were weakly but positively tied to changes in their Elo ratings. However, the multilayer network approach offered additional insights into this social process, identifying how changes in a male’s centrality cascade through the other network layers. This dynamic view indicates that the changes in Elo ratings are likely to be short-lived, but that male centrality within the female network had a much stronger impact throughout the multilayer network as a whole, especially on reducing intermale aggression (i.e., aggression directed by males toward other males). We suggest that multilayer social network approaches can take advantage of increased amounts of social data that are more commonly collected these days, using a variety of methods. Such data are inherently multilevel and multilayered, and thus offer the ability to quantify more precisely the dynamics of animal social behaviors.

强大的女性群体：男性社会融入女性网络和动态多层网络的价值

多层网络技术的发展对于希望了解不同交互层如何相互影响以及这些交互层又如何影响群体动态的研究人员来说是福音。在这里，我们调查男性和女性的修饰和攻击性互动网络之间的整合如何影响黑长尾猴Chyrocebus pygerythrus中的男性力量轨迹。我们以前对这种现象的分析使用的是单层方法，我们的目标是使用动态多层方法扩展这些分析。为此，我们构造了男女互动层的时间序列。然后，我们使用多元多级自回归模型来比较男性在女性修饰层中的中心地位与男性Elo等级变化之间的交叉滞后关联。我们的研究结果证实了我们最初的发现：女性美容网络中男性中心地位的变化与Elo等级的变化较弱，但正相关。但是，多层网络方法提供了对该社交过程的更多见解，从而确定了男性中心性的变化如何通过其他网络层级联。这种动态的观点表明，Elo等级的变化可能是短暂的，但是女性在整个网络中的男性中心地位对整个多层网络的影响要大得多，尤其是在减少男性间的侵略性（即由男性主导的侵略性）方面。男性对其他男性）。我们建议，多层社交网络方法可以利用多种方法来利用当今越来越普遍收集的越来越多的社交数据。这样的数据本质上是多层次的和多层的，因此提供了更精确地量化动物社会行为动态的能力。男性对其他男性的侵略）。我们建议，多层社交网络方法可以利用多种方法来利用当今越来越普遍收集的越来越多的社交数据。这样的数据本质上是多层次的和多层的，因此提供了更精确地量化动物社会行为动态的能力。男性对其他男性的侵略）。我们建议，多层社交网络方法可以利用多种方法来利用当今越来越普遍收集的越来越多的社交数据。这样的数据本质上是多层次的和多层的，因此提供了更精确地量化动物社会行为动态的能力。
