Fungi are crucial for terrestrial ecosystems, yet the role of fungal diversity in ecosystem functions remains unclear. We synthesize fungal biodiversity and ecosystem function (BEF) relationships, focusing on plant biomass production, carbon storage, decomposition, and pathogen or parasite resistance. The observed BEF relationships for these ecosystem functions vary in strength and direction, complicating generalizations. Strong positive relationships are generally observed when multiple ecosystem functions are addressed simultaneously. Often, fungal community composition outperforms species richness in predicting ecosystem functions. For more comprehensive fungal BEF research, we recommend studying natural communities, considering the simultaneous functions of a broader array of fungal guilds across spatiotemporal scales, and integrating community assembly concepts into BEF research. For this, we propose a conceptual framework and testable hypotheses.
真菌对陆地生态系统至关重要，然而真菌多样性在生态系统功能中的作用仍不明确。我们综合了真菌生物多样性与生态系统功能（BEF）之间的关系，重点关注植物生物量生产、碳储存、分解以及对病原体或寄生虫的抗性。这些生态系统功能所观察到的BEF关系在强度和方向上各不相同，使得进行概括变得复杂。当同时考虑多种生态系统功能时，通常会观察到强烈的正相关关系。在预测生态系统功能方面，真菌群落组成往往比物种丰富度表现得更好。为了开展更全面的真菌BEF研究，我们建议研究自然群落，考虑跨时空尺度更广泛的真菌类群的同时功能，并将群落组装概念纳入BEF研究。为此，我们提出了一个概念框架和可检验的假设。
