Biomass data were collected in the garden pot experiment from five community types in April 2017. Explanation to column headings: "Target species" = one of 49 species used in the experiment; "Competitor species" = one of two competitor species (Arrhenatherum elatius or Origanum vulgare) used in the experiment; "Community type" = see Fig. 1 in "Dostál P. et al. (2018) Linking species abundance and overyielding from experimental communities with niche and fitness characteristics. Journal or Ecology" for details how five community types were constructed; "#Target individuals planted"= number of target species individuals planted per pot; "#Competitor individuals planted"= number of target species individuals planted per pot; "Inoculum" = identity of species from the first (conditioning) phase serving as a source of soil inoculum in the second experimental phase (HET indicates heterospecific incululum prepared by mixing first-phase soils of all 49 target species); "Target biomass (g, per pot)" = total target species biomass estimated in a pot; "Target biomass (mg, per 1 planted ind.)" = biomass per single planted individual of target species; "Competitor biomass (g, per pot)" = total competitor species biomass estimated in a pot; "Competitor biomass (mg, per 1 planted ind.)" = biomass per single planted individual of competitor species.

本研究于2017年4月通过盆栽园艺实验，针对5种群落类型采集了生物量数据。各列表头说明如下：「目标物种（Target species）」指实验中使用的49个物种之一；「竞争者物种（Competitor species）」指实验中使用的2种竞争者物种之一，即巨序剪股颖（Arrhenatherum elatius）或牛至（Origanum vulgare）；「群落类型（Community type）」的具体构建细节，请参见Dostál P.等人2018年发表于《Journal of Ecology》的论文《Linking species abundance and overyielding from experimental communities with niche and fitness characteristics》中的图1；「种植目标个体数（#Target individuals planted）」为每个盆栽中种植的目标物种个体数量；「种植竞争者个体数（#Competitor individuals planted）」为每个盆栽中种植的目标物种个体数量；「接种物（Inoculum）」指第二实验阶段中作为土壤接种物来源的第一阶段（预培养阶段）的物种标识，其中HET表示异种接种物，即通过混合全部49种目标物种的第一阶段土壤制备得到的接种物；「目标物种生物量（g, per pot）」为单个盆栽中测得的目标物种总生物量；「目标物种单株生物量（mg, per 1 planted ind.）」为目标物种单个定植个体的生物量；「竞争者物种生物量（g, per pot）」为单个盆栽中测得的竞争者物种总生物量；「竞争者物种单株生物量（mg, per 1 planted ind.）」为竞争者物种单个定植个体的生物量。
