The effects of biodiversity on ecosystem functioning generally increase over time, but the underlying processes remain unclear. Using 26 long-term grassland and forest experimental ecosystems, we demonstrate that biodiversity-ecosystem functioning relationships strengthen mainly by greater increases in functioning in high-diversity communities in grasslands and forests. In grasslands, biodiversity effects also strengthen due to decreases in functioning in low-diversity communities. Contrasting trends across grasslands are associated with differences in soil characteristics.
生物多样性对生态系统功能的影响通常随着时间的推移而增加，但背后的过程仍不清楚。利用 26 个长期的草地和森林实验生态系统，我们证明生物多样性-生态系统功能关系主要通过在草地和森林高多样性群落中功能的更大增加而加强。在草原中，由于低多样性群落中功能的降低，生物多样性效应也在加强。草原上的对比趋势与土壤特性的差异有关。
