Many ecological community dynamics display some degree of directionality, known as succession patterns. But complex interaction networks frequently tend to non‐directional dynamics such as chaos, unless additional structures or mechanisms impose some form of, often fragile or shot‐lived, directionality. We exhibit here a novel property of emergent long‐lasting directionality in competitive communities, which relies on very minimal assumptions.

方向性和社区级别的选择

许多生态群落动力学表现出一定程度的方向性，称为演替模式。但是，复杂的交互网络通常倾向于无方向性的动态变化，例如混乱，除非其他结构或机制强加了某种形式的（通常是易碎的或命中注定的）方向性。在这里，我们展示了一种新颖的特性，即在竞争性社区中出现了持久的方向性，这是基于非常小的假设。
