The distance decay of microbial community composition in municipal wastewater treatment bioreactors

Understanding the spatiotemporal patterns of biodiversity is a central goal of ecology. The objective of this study was to better understand the biogeography of activated sludge microbial communities, which are practically important for the protection of surface water quality. Monthly samples were collected from 20 facilities (25 bioreactors) within 442-km of each other for one year.

解析生物多样性的时空分布模式是生态学的核心研究目标。本研究旨在深入阐明活性污泥微生物群落的生物地理学特征，此类群落对于保障地表水环境质量具有重要的实际应用价值。本研究历时一年，从彼此间距不超过442公里的20处设施（共计25个生物反应器）中按月采集样本。
