Co-occurence data. Population = replicate population; distance = distance between focal species and competitor; feedback = the measured feedback between each pair of focal X soil-conditioning species (see methods in paper) calculated for above-, belowground, and total biomass.共现数据。种群=重复种群（replicate population）；距离=目标物种（focal species）与竞争物种（competitor）之间的距离；反馈=针对每一对目标X土壤调控物种（soil-conditioning species）所测得的交互反馈效应（详见论文方法部分），该效应分别针对地上生物量、地下生物量及总生物量计算得出。
