小组根据将单个微生物菌株划分为更广泛类别的粗略描述的预测能力，定义了微生物生态系统的紧急可预测性。该课题组人员对两个已发表的数据集进行了主题化，以表明粗糙的描述对物种丰富的群落更具预测性。这种行为不能用大型社区的简单平均效应来解释。相反，他们的分析表明，当生理或环境反馈抵消了这些沿特定群落变异轴的平均效应时，突发的可预测性就会出现，从而使这些轴随着多样性的增加而变得更有信息量。
据了解，微生物生态学的一个长期假设是，尽管群落复杂，但简单的模式可能会持续存在，甚至因为它而出现。然而，“紧急简单性”的概念仍然是部分直观的。

Abstract: A long-standing hypothesis of microbial ecology is that simple patterns might persist despite community complexity or even emerge because of it. However, the concept of “emergent simplicity” remains partly intuitive. Here, we defined emergent predictability of microbial ecosystems based on the predictive power of coarsened descriptions that group individual microbial strains into broader classes. We used two published datasets to show that coarse descriptions became more predictive for more species-rich communities. This behavior was not explained by simple averaging effects in large communities. To the contrary, our analysis indicates that emergent predictability arises when physiological or environmental feedback counteracts these averaging effects along certain axes of community variation, allowing these axes to become more informative as diversity increases.
