How the coexistence of many species is maintained is a fundamental and unresolved question in ecology. Coexistence is a puzzle because we lack a mechanistic understanding of the variation in species presence and abundance. Whether variation in ecological communities is driven by deterministic or random processes is one of the most controversial issues in ecology. Here, I study the variation of species presence and abundance in microbial communities from a macroecological standpoint. I identify three macroecological laws that quantitatively characterize the fluctuation of species abundance across communities and over time. Using these three laws, one can predict species’ presence and absence, diversity, and commonly studied macroecological patterns. I show that a mathematical model based on environmental stochasticity, the stochastic logistic model, quantitatively predicts the three macroecological laws, as well as non-stationary properties of community dynamics.

宏观生态规律描述了微生物群落的变异和多样性。

如何维持多种物种的共存是生态学中一个基本的、悬而未决的问题。共存是一个难题,因为我们缺乏对物种存在和丰度变化的机械理解。生态群落的变化是由确定性过程还是随机过程驱动是生态学中最具争议的问题之一。在这里,我从宏观生态学的角度研究微生物群落中物种存在和丰度的变化。我确定了三个宏观生态定律,它们定量地描述了跨社区和随时间推移的物种丰度波动。使用这三个定律,可以预测物种的存在与否、多样性和普遍研究的宏观生态模式。我展示了一个基于环境随机性的数学模型,即随机逻辑模型,
