昆虫群体是分散的系统，采用任务分配，其中个人承担不同的角色，以满足群体的需要，如蜜蜂“护士”，“巢工”和“觅食者”。然而，在何种程度上个人可以很好地分类离散的“角色”，他们如何改变行为，从一天到一天，在整个生命周期，并与环境条件，是知之甚少。通过长期自动跟踪超过4，200只单独识别的蜜蜂Apis mellifera，我们使用行为指标来量化和比较行为。我们发现，个人表现出行为的变化沿着两个主导轴，代表巢基板的使用和运动内的巢。在一生中，我们发现个体在觅食开始时有所不同，某些蜜蜂在运动模式上表现出终身的差异。此外，我们研究了一段时间的突然花蜜的可用性，蜂蜜存储超过6天的三倍，并看到殖民地表现出分布的活动，不需要大规模的殖民地重组的转变。我们的定量方法显示了集体单位如何在不同的日子和生命周期，以及如何来源的变化和变异有助于殖民地的强大而灵活的反应。
Insect colonies are decentralized systems that employ task allocation, whereby individuals undertake different roles to fulfil colony needs, such as honey bee “nurses”, “nest workers”, and “foragers”. However, the extent to which individuals can be well-classified by discrete “roles”, how they change behavior from day-to-day, over entire lifetimes, and with environmental conditions, is poorly understood. Using long-term automated tracking of over 4,200 individually-identified bees Apis mellifera, we use behavioral metrics to quantify and compare behavior. We show that individuals exhibit behavioral variation along two dominant axes that represent nest substrate use and movement within the nest. Across lifetimes, we find that individuals differ in foraging onset, and that certain bees exhibit lifelong consistencies in their movement patterns. Furthermore, we examine a period of sudden nectar availability where the honey stores tripled over 6 days, and see that the colony exhibits a distributed shift in activity that did not require a large-scale colony reorganization. Our quantitative approach shows how collective units differ over days and lifetimes, and how sources of variation and variability contribute to the colony’s robust yet flexible response.
