植物可以通过多种方式影响土壤群落的组成。然而，目前还不清楚是否植物群落属性的信息，包括分类，系统发育，或基于性状的组成，可以用来预测土壤群落的结构。我们测试，在单一栽培和实地生长的混合温带草原社区，植物属性是否预测土壤群落，包括整个生命树（真菌，细菌，原生生物和后生动物）的分类组。所有的土壤群落组的组成受到植物物种的身份，无论是在单作和混合社区。此外，植物群落组成预测土壤群落组成的变化超出了可以预测的土壤非生物特征。此外，地上植物群落组成和植物根系组成的分析表明，植物群落属性是更好的预测土壤群落比根系分布。然而，无论是植物发育，也没有植物性状是强有力的预测土壤群落在任何一个实验。我们的研究结果表明，草地植物物种形成特定的协会与土壤群落成员和植物物种分布的信息可以提高土壤群落组成的预测。这些结果表明，植物物种和复杂的土壤群落之间的特定关联是草原土壤生物多样性格局的关键决定因素。
There are numerous ways in which plants can influence the composition of soil communities. However, it remains unclear whether information on plant community attributes, including taxonomic, phylogenetic, or trait-based composition, can be used to predict the structure of soil communities. We tested, in both monocultures and field-grown mixed temperate grassland communities, whether plant attributes predict soil communities including taxonomic groups from across the tree of life (fungi, bacteria, protists, and metazoa). The composition of all soil community groups was affected by plant species identity, both in monocultures and in mixed communities. Moreover, plant community composition predicted additional variation in soil community composition beyond what could be predicted from soil abiotic characteristics. In addition, analysis of the field aboveground plant community composition and the composition of plant roots suggests that plant community attributes are better predictors of soil communities than root distributions. However, neither plant phylogeny nor plant traits were strong predictors of soil communities in either experiment. Our results demonstrate that grassland plant species form specific associations with soil community members and that information on plant species distributions can improve predictions of soil community composition. These results indicate that specific associations between plant species and complex soil communities are key determinants of biodiversity patterns in grassland soils.
