论文摘要:Intensive agriculture has significantly decreased soil biodiversity, which could reshape biodiversity patterns across landscapes and ecosystems. Here, we conducted a soil survey of 941 plots of agricultural and adjacent natural ecosystems (e.g. forest, wetland, grassland and desert) in 38 regions across diverse climatic and soil gradients. Using a framework of multi-scales community assembly, we revealed that the regional species pool was an important predictor of agricultural bacterial diversity, and explained a unique variation that cannot be predicted by historical legacy, large-scale environmental factors, and local community assembly processes. This study revealsthe indubitable role of regional species pool from adjacent natural ecosystems in predicting bacterial diversity, which has useful implication for biodiversity management and conservation in agricultural systems.

集约化农业显著降低了土壤生物多样性,这可能重塑景观和生态系统的生物多样性模式。研究通过对 38 个地区不同气候和土壤梯度的 941 个农业和邻近自然生态系统(森林、湿地、草原和沙漠)样地进行了土壤调查。使用多尺度群落构建框架,研究揭示了区域物种库是农业细菌多样性的重要预测因素,并解释了历史遗留、大尺度环境因子和局域群落构建过程无法预测的独特变化,表明邻近自然生态系统的区域物种库在预测细菌多样性方面的不可忽视的作用,这对农业系统的生物多样性管理和保护具有有益的意义。
