Ecosystem functioning depends on biodiversity at multiple trophic levels, yet relationships between multitrophic diversity and ecosystem multifunctionality have been poorly explored, with studies often focusing on individual trophic levels and functions and on specific ecosystem types. Here, we show that plant diversity can affect ecosystem functioning both directly and by affecting other trophic levels. Using data on 13 trophic groups and 13 ecosystem functions from two large biodiversity experiments—one representing temperate grasslands and the other subtropical forests—we found that plant diversity increases multifunctionality through elevated multitrophic diversity. Across both experiments, the association between multitrophic diversity and multifunctionality was stronger than the relationship between the diversity of individual trophic groups and multifunctionality. Our results also suggest that the role of multitrophic diversity is greater in forests than in grasslands. These findings imply that, to promote sustained ecosystem multifunctionality, conservation planning must consider the diversity of both plants and higher trophic levels.

植物多样性通过多营养多样性增强生态系统多功能性
生态系统的功能取决于多个营养级的生物多样性,但多营养多样性和生态系统多功能性之间的关系研究不足,研究通常集中在单个营养级和功能以及特定的生态系统类型上。在这里,我们表明植物多样性可以直接影响生态系统功能,也可以通过影响其他营养级来影响生态系统功能。使用来自两个大型生物多样性实验(一个代表温带草原,另一个代表亚热带森林)的 13 个营养类群和 13 种生态系统功能的数据,我们发现植物多样性通过提高多营养多样性来增加多功能性。在这两个实验中,多营养多样性和多功能性之间的关联性强于单个营养类群的多样性与多功能性之间的关系。我们的研究结果还表明,多营养多样性在森林中的作用大于在草原中的作用。这些发现意味着,为了促进生态系统的可持续多功能性,保护规划必须考虑植物的多样性和更高的营养级。
