Decades of experimental research have conclusively shown a positive relationship between species richness and ecosystem function. However, authoritative reviews find no consensus on how species loss affects function in natural communities. We analyse experimental and observational data in an identical way and test whether they produce similar results.

物种丧失在实验中驱动生态系统功能，但在自然界中，物种丧失的重要性取决于优势

数十年的实验研究最终表明物种丰富度与生态系统功能之间存在正相关关系。但是，权威的评论未就物种流失如何影响自然群落功能达成共识。我们以相同的方式分析实验和观察数据，并测试它们是否产生相似的结果。
