优先效应通常用于描述一系列广泛的现象，这些现象反映了物种到达顺序对生态群落多样性、组成和功能的影响。一些研究建议围绕共存理论的稳定和平等概念重新构建优先效应。我们发现，唯一兼容的优先级效应是那些具有正的频率依赖性，无论它们是否出现在平衡或非平衡系统。
Priority effects are commonly used to describe a broad suite of phenomena capturing the influence of species arrival order on the diversity, composition and function of ecological communities. Several studies have suggested reframing priority effects around the stabilizing and equalizing concepts of coexistence theory. We show that the only compatible priority effects are those characterized by positive frequency-dependence, irrespective of whether they emerge in equilibrium or non-equilibrium systems.
