当个体遵循共同的互动规则时，集体行为可以自发出现。然而，由于种群中存在遗传和非遗传变异，每个个体的行为不同。目前尚不清楚这种个性是如何实现集体行为的。我们量化的clonalEscherichia colicells，集体迁移沿着一个通道，通过以下一个自我产生的吸引剂梯度带的个性。我们发现，尽管个体趋化能力存在很大差异，但细胞能够通过在移动带内自发地将自己分类而作为一个连贯的群体迁移。这种分类机制确保个体趋化能力之间的差异通过每个个体必须导航的行进梯度的局部陡度的差异来补偿，并确定与带一起行进所需的最低性能。通过解决个体性和集体迁移之间的冲突，这一机制使人口能够在迁移过程中保持有利的多样性。
Collective behavior can spontaneously emerge when individuals follow common rules of interaction. However, the behavior of each individual differs due to existing genetic and non-genetic variation within the population. It remains unclear how this individuality is managed to achieve collective behavior. We quantify individuality in bands of clonalEscherichia colicells that migrate collectively along a channel by following a self-generated gradient of attractant. We discover that despite substantial differences in individual chemotactic abilities, the cells are able to migrate as a coherent group by spontaneously sorting themselves within the moving band. This sorting mechanism ensures that differences between individual chemotactic abilities are compensated by differences in the local steepness of the traveling gradient each individual must navigate, and determines the minimum performance required to travel with the band. By resolving conflicts between individuality and collective migration, this mechanism enables populations to maintain advantageous diversity while on the move.
