论文摘要
生态学家提出了许多共存的解释，但这只是部分解释。自然很复杂，因此可以合理地假设在任何给定的生态界，共存的多种机制同时运行。在这里，我们提出了一种基于现代共存理论的扩展，可以量化不同解释对共存的相对重要性的方法。现代共存理论的当前版本仅允许分析受到空间或时间环境变化影响的社区，但并非两者兼而有之。我们展示了如何通过时空波动分析社区，如何解析空间变化和时间变化的重要性，以及如何使用数学表达式或模拟实验来测量一切。我们对现代共存理论的扩展使经验主义者可以使用现实的模型和更多数据来更好地推断真实社区共存的机制。
Ecologists have put forward many explanations for coexistence, but these are only partial explanations; nature is complex, so it is reasonable to assume that in any given ecological community, multiple mechanisms of coexistence are operating at the same time. Here, we present a methodology for quantifying the relative importance of different explanations for coexistence, based on an extension of Modern Coexistence Theory. Current versions of Modern Coexistence Theory only allow for the analysis of communities that are affected by spatial or temporal environmental variation, but not both. We show how to analyze communities with spatiotemporal fluctuations, how to parse the importance of spatial variation and temporal variation, and how to measure everything with either mathematical expressions or simulation experiments. Our extension of Modern Coexistence Theory allows empiricists to use realistic models and more data to better infer the mechanisms of coexistence in real communities.
