Fine root traits underpin terrestrial ecosystem functioning. Despite ongoing plant diversity loss due to anthropogenic activities, our understanding of the effects of plant diversity on fine root traits remains elusive. We addressed: (a) Do fine roots modify their traits in response to species mixtures? (b) Do these responses change with the species richness in mixtures, stand age, and soil depth? (c) Do plant‐mixture induced responses of root traits differ across terrestrial ecosystems?

陆地生态系统中细根生物量和性状对植物物种混合物的全球响应

优良的根性状巩固了陆地生态系统的功能。尽管由于人为活动导致植物多样性不断丧失，但我们对植物多样性对优良根系性状的影响的了解仍然难以捉摸。我们解决了以下问题：（a）细根是否会响应物种混合而改变其性状？（b）这些反应是否随混合物中物种的丰富度，林分年龄和土壤深度而变化？（c）植物混合物引起的根性状响应在陆地生态系统中是否不同？
