近年来，对照实验极大地提高了我们对生物多样性变化和生态系统功能(BEF)之间联系的理解。然而，关于BEF实验是否与复杂的生态系统以及在保护和管理方面感兴趣的大空间和时间尺度的相关性，仍存在争议。在这里，我要解决一些关于BEF实验研究的持续批评，并认为这些批评被夸大了。与一些建议相反，许多归因于实验的假定文物使他们关于BEF联系的结论更强，而不是更弱。与其他广泛的生态概念一样，BEF侧重于一般模式，而不是着眼于物种层面的应用保护问题。然而，迄今进行的BEF实验的洞察力可能会低估而不是高估生物多样性对现实世界生态系统功能和生态系统服务提供的重要性。这些实验表明，管理生态系统以促进生物多样性可能具有重要的实际好处。
Controlled experiments have substantially advanced our understanding of the links between changing biodiversity and ecosystem functioning (BEF) in recent years. However, controversy continues regarding the relevance of BEF experiments to the complex ecosystems and large spatial and temporal scales of interest in conservation and management. Here, I address some of the persistent criticisms regarding experimental BEF research and argue that these have been overstated. Contrary to some suggestions, many putative artifacts attributed to experiments render their conclusions about BEF links stronger, rather than weaker. Like other broad ecological concepts, BEF focuses on general patterns, rather than looking at species-level, applied conservation problems. Nevertheless, insights from BEF experiments conducted to date are likely to underestimate, rather than overestimate, the importance of biodiversity to ecosystem functioning and the provision of ecosystem services in the real world. These experiments suggest that managing ecosystems to promote biodiversity can have important practical benefits.
