在动物社会中，个体可以扮演不同的角色来满足自己和群体的需要。蚁群显示出高度的组织复杂性，蚂蚁在不同的时间尺度上扮演不同的角色（即所谓的任务分配）。影响任务分配的因素可以是个人层面（如生理学），也可以是群体层面（如互动网络）。我们使用先前发表的数据集（梅尔施等人，2013，Science，340（6136），1090-1093）追踪六个Camponotus fellahcolony在41天内的行为。在我们的新分析中，我们的目标是更好地解释任务转换的嘈杂过程，而不仅仅是简单的年龄多民族主义。首先，我们研究了使用节点（个人）水平的网络措施和它们的关系，个人的任务-觅食，清洁或护理-以及蚂蚁是否切换任务的互动网络的架构。然后，我们探讨了如何嘈杂的信息传播蚂蚁之间，作为一个功能的殖民地组成（多少蚂蚁进行哪些任务），通过信息理论的度量“有效信息”。我们的研究结果表明，互动历史与任务分配有关：切换到任务的蚂蚁更有可能与执行该任务的其他蚂蚁互动。交互作用与任务分配的相关程度，以及这些交互作用中的噪音，取决于哪些蚂蚁群体正在进行交互。总体而言，我们发现，即使蚂蚁水平的网络措施变化更蚂蚁时，他们切换功能组的群体凝聚力是稳定的，因此，蚁群保持了高水平的信息流所确定的网络分析，蚂蚁功能组发挥不同的作用，通过不同的信息流在维持群体凝聚力。
In animal societies, individuals may take on different roles to fulfil their own needs and the needs of their group. Ant colonies display high levels of organizational complexity, with ants fulfilling different roles at different timescales (what is known as task allocation). Factors affecting task allocation can be at the individual level (e.g. physiology), or at the group level (e.g. the network of interactions). We focus on group level processes by exploring the relationship between interaction networks, task allocation and task switching using a previously published data set (Mersch et al., 2013,Science, 340(6136), 1090–1093) tracking the behaviour of sixCamponotus fellahcolonies over 41 days. In our new analyses, our goal was to better explain the noisy process of task switching beyond simple age polyethism. First, we investigated the architecture of interaction networks using node (individual) level network measures and their relation to the individual's task – foraging, cleaning or nursing – and whether or not the ant switched tasks. We then explored how noisy information propagation was among ants, as a function of the colony composition (how many ants carried out which tasks), through the information-theoretic metric of ‘effective information’. Our results show that interaction history is tied to task allocation: ants that switched to a task were more likely to have interacted with other ants carrying out that task. The degree to which interactions related to task allocation, as well as the noise in those interactions, depended on which groups of ants were interacting. Overall, we found that colony cohesion was stable even as ant level network measures varied more for ants when they switched functional groups; thus, ant colonies maintained a high level of information flow as determined by network analysis, and ant functional groups played different roles in maintaining colony cohesion through varied information flows.
