Disturbance can profoundly modify the structure of natural communities. However, microbial ecologists' concept of "disturbance" has often deviated from conventional practice. Definitions (or implicit usage) have frequently included climate change and other forms of chronic environmental stress, which contradict the macrobiologist's notion of disturbance as a discrete event that removes biomass. Physical constraints and disparate biological characteristics were compared to ask whether disturbances fundamentally differ in microbial and macroorganismal communities. A definition of "disturbance" for microbial ecologists is proposed that distinguishes from "stress" and other competing terms, and that is in accord with definitions accepted by plant and animal ecologists.
干扰能够深刻改变自然群落的结构。然而，微生物生态学家对“干扰”的概念常常偏离传统认知。其定义（或隐含用法）常常涵盖气候变化及其他形式的慢性环境压力，这与宏观生物学家将干扰视为去除生物量的离散事件的概念相矛盾。我们比较了物理限制和不同的生物学特征，以探究干扰在微生物群落和宏观生物群落中是否存在根本差异。本文提出了一个适用于微生物生态学家的“干扰”定义，该定义与“压力”及其他相关术语相区分，且与植物和动物生态学家所接受的定义相一致。
