Plant–microbe interactions change along a tallgrass prairie restoration chronosequence

摘要: Soil microbial communities are critical in determining the performance and density of species plant communities. However, their role regulating success restorations is much less clear. This study assessed ability soil to regulate growth two potentially dominant grasses common forbs tallgrass prairie restorations. Specifically, we examined effects along a restoration chronosequence from agricultural fields remnant prairies using experimentally inoculated soils. The grass species, Andropogon gerardii Sorghastrum nutans, grew best with inoculates experienced decline later stages chronosequence, indicating that community shifted being beneficial early inhibiting restoration. Growth forb, Silphium terebinthinaceum, varied little inoculation or position chronosequence. Baptisia leucantha, legume, appeared limited by nodule formation soils, peaked young soils formation, but decreased older as became more antagonistic. Overall, negative feedbacks tended be important restoration, restored prairies. Our results provide evidence it may advantageous for management practices take into consideration when trying recreate diversity
