对自组织群体（如鱼群或鸟群）的研究试图揭示个体使用的行为规则（局部水平的相互作用）来协调他们的运动（全球水平的模式）。然而，实证研究往往侧重于短期或一次性的观察，协调已经建立或描述不同的协调状态之间的过渡。因此，我们对行为规则如何发展以及在群体中如何维持缺乏了解。在这里，我们研究的出现和重复性的协调运动在浅滩的棘鱼（Gasterosteus aculeatus）。将浅滩引入到一个简单的环境中，通过视频分析推断其时空位置。使用鱼的速度和小波分析的鱼的位置之间的方向相关性，我们演示了如何浅滩，最初不协调的运动迅速过渡到一个协调的状态与定义的个人领导者-追随者的角色。领导者和追随者的身份在两次试验中是可重复的，并且在第二次试验期间和具有较高活动水平的鱼类组（试验前测试）更快地达到协调。在棘鱼群中协调运动和社会角色的可重复性的快速出现可能会减少野外社会互动的不确定性，在野外，个体生活在一个具有高裂变融合动力学和非随机关联模式的系统中。鱼群和鸟群的协调运动令人着迷。科学家们已经发现了产生这些令人惊叹的运动模式的相互作用，但重点是已经建立协调的情况。在这里，我们表明，棘鱼实现协调运动，快速建立定义的角色，其中一些鱼作为领导者和其他追随者，这些角色是相同的，当同一条鱼再次测试。
Studies of self-organizing groups like schools of fish or flocks of birds have sought to uncover the behavioral rules individuals use (local-level interactions) to coordinate their motion (global-level patterns). However, empirical studies tend to focus on short-term or one-off observations where coordination has already been established or describe transitions between different coordinated states. As a result, we have a poor understanding of how behavioral rules develop and are maintained in groups. Here, we study the emergence and repeatability of coordinated motion in shoals of stickleback fish (Gasterosteus aculeatus). Shoals were introduced to a simple environment, where their spatio-temporal position was deduced via video analysis. Using directional correlation between fish velocities and wavelet analysis of fish positions, we demonstrate how shoals that are initially uncoordinated in their motion quickly transition to a coordinated state with defined individual leader-follower roles. The identities of leaders and followers were repeatable across two trials, and coordination was reached more quickly during the second trial and by groups of fish with higher activity levels (tested before trials). The rapid emergence of coordinated motion and repeatability of social roles in stickleback fish shoals may act to reduce uncertainty of social interactions in the wild, where individuals live in a system with high fission-fusion dynamics and non-random patterns of association. The coordinated motion of schools of fish and flocks of birds is fascinating to watch. Scientists have uncovered the interactions that produce these stunning patterns of motion, but focus on situations where coordination has already been established. Here we show that stickleback fish achieve coordinated motion by quickly establishing defined roles where some fish act as leaders and others as followers, and these roles are the same when the same fish are tested again.
