优先效应在构建自然群落中起着关键作用，但关于它们如何影响不同的生态系统，仍然存在相当大的困惑。综合以往的研究，我们表明，这种混乱的出现，因为驱动优先级的机制和时间尺度，他们在不同的研究之间的运作，导致不同的结果在物种之间的相互作用和生物多样性模式。我们建议分组优先级效应分为两个功能类别的基础上，他们的机制：频率依赖的优先级效应，产生积极的频率依赖，和性状依赖的优先级效应，产生的时间依赖性的变化相互作用的性状。通过从实验中轻松量化这些类别，我们可以构建代表不同生物机制和优先效应相互作用的社区模型，从而更好地预测其在生态系统中的后果。
Priority effects play a key role in structuring natural communities, but considerable confusion remains about how they affect different ecological systems. Synthesizing previous studies, we show that this confusion arises because the mechanisms driving priority and the temporal scale at which they operate differ among studies, leading to divergent outcomes in species interactions and biodiversity patterns. We suggest grouping priority effects into two functional categories based on their mechanisms: frequency-dependent priority effects that arise from positive frequency dependence, and trait-dependent priority effects that arise from time-dependent changes in interacting traits. Through easy quantification of these categories from experiments, we can construct community models representing diverse biological mechanisms and interactions with priority effects, therefore better predicting their consequences across ecosystems.
