| Research Abstract |
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.
