Body size is a key ecological trait of soil microorganisms related to their adaptation to environmental changes. In this study, we reveal that the smaller microorganisms show stronger community resistance than larger organisms in both maize and rice soil. Compared with larger organisms, smaller microorganisms have higher diversity and broader niche breadth to deploy survival strategies, because of which they are less affected by environmental selection and thus survive in complex and various kinds of environments. In addition, the strong correlation between smaller microorganisms and ecosystem functions reflects their greater metabolic flexibility and illustrates their significant roles in adaptation to continuously changing environments. This research highlights the importance of body size in maintaining stability of the soil microbiome and forecasting agroecosystem dynamics under environmental disturbances.
体型大小是土壤微生物的一个关键生态特征，与其对环境变化的适应性相关。在本研究中，我们发现，在玉米和水稻土壤中，较小的微生物群落比大型微生物表现出更强的抵抗力。与大型微生物相比，较小的微生物具有更高的多样性和更广泛的生态位宽度来部署生存策略，因此它们受环境选择的影响较小，从而能在复杂多样的环境中生存。此外，较小的微生物与生态系统功能之间的强相关性反映了它们更大的代谢灵活性，并说明了它们在适应不断变化的环境中的重要作用。这项研究突出了体型大小在维持土壤微生物群落稳定性以及预测环境干扰下农业生态系统动态方面的重要性。
