摘要
How the coexistence of many 物種 is maintained is a fundamental and unresolved question in 生態學. Coexistence is a puzzle because we lack a mechanistic understanding of the variation in 物種 presence and abundance. Whether variation in ecological communities is driven by deterministic or random processes is one of the most controversial issues in 生態學. Here, I study the variation of 物種 presence and abundance in microbial communities from a macroecological standpoint. I identify three macroecological laws that quantitatively characterize the fluctuation of 物種 abundance across communities and over time. Using these three laws, one can predict 物種’ presence and absence, 多樣性, and commonly studied macroecological patterns. I show that a 數學 model based on environmental 隨機ity, the 隨機 logistic model, quan
