描述物种丰富度和面积大小之间关系的幂律是生态学中为数不多的概括之一，但最近的研究表明，这种关系对微生物来说是不同的。我们证明了栖息在小的水生岛屿（树洞）的自然细菌群落确实遵循物种面积定律。这一结果需要重新评估目前对自然微生物群落如何运作的理解，并意味着类似的过程构成了微生物群落和较大生物体的群落。
The power law that describes the relationship between species richness and area size is one of the few generalizations in ecology, but recent studies show that this relationship differs for microbes. We demonstrate that the natural bacterial communities inhabiting small aquatic islands (treeholes) do indeed follow the species-area law. The result requires a re-evaluation of the current understanding of how natural microbial communities operate and implies that analogous processes structure both microbial communities and communities of larger organisms.
