Study on mechanisms of species diversity based on the interaction between plants and fungi, and ecosystem functions

在温带森林中，我们发现明确的证据表明，负反馈与病原真菌和菌根真菌的正反馈强烈地决定了幼苗的性能和随之而来的物种多样性。在荫蔽的森林林下，主机特定的病原体造成幼苗死亡，特别是同种，增加物种多样性。与此相反，宿主特异性菌根真菌促进幼苗的性能，特别是同种的差距，降低了多样性。在人工针叶林的不同物种多样性，我们发现，这两个生态系统功能（即）增加的物种多样性。

In a temperate forest, we found clear evidences that both negative-feedback with pathogenic fungi and positive-feedback with mycorrhizal fungi strongly determine the seedling performance and consequent species-diversity. In shaded forest understory, host-specific pathogens caused seedling death particularly for conspecifics,increasing species-diversity. In contrast, the host-specific mycorrhizal fungi facilitated seedling performance particularly for conspecifics in gaps, decreasing the diversity.In artificial conifer forests of different species diversity, we revealed that both the ecosystem functions (i.e. ) increased with increasing the species diversity.
