在许多物种中，群体凝聚力可能是对立力量(例如，躲避捕食者和争夺食物)之间妥协的结果。然而，关于群体凝聚力动态的实证数据很少。我们展示了斑马鱼鱼群的瞬间位置数据，并分析了个体间距离的时间变化。我们证明，鱼群成员之间的距离不会像以前假设的那样固定在任何给定值，而是在5到15 S之间振荡。(C)2008爱思唯尔B.V.保留所有权利。
In many species, group cohesion maybe the result of a compromise between opposing forces (e.g. predator avoidance and competition for food). However, little empirical data exists on the dynamics of group cohesion. We present moment-to-moment positional data on zebrafish shoals and analyze temporal changes in inter-individual distances. We demonstrate that the distance between shoal members does not settle at any given value, as has previously been assumed, but oscillates with a period between 5 and 15 s. (C) 2008 Elsevier B.V.
