摘要
To advance understanding of 生物多樣性 and ecosystem function, ecologists seek widely applicable relationships among 物種 多樣性 and other ecosystem characteristics such as 物種 productivity, biomass, and abundance. These metrics vary widely across ecosystems and no relationship among any combination of them that is valid across habitats, taxa, and spatial scales, has heretofore been found. Here we derive such a relationship, an equation of state, among 物種 richness, energy flow, biomass, and abundance by combining results from the Maximum 熵 Theory of 生態學 and the Metabolic Theory of 生態學. It accurately captures the relationship among these state variables in 42 data sets, including vegetation and arthropod communities, that span a wide variety of spatial scales and habitats. The success of our ecologica
