Contrasting effects of intra- and interspecific identity and richness of ectomycorrhizal fungi on host plants, nutrient retention and multifunctionality

摘要

A major gap in our understanding of biodiversity-ecosystem function relationships concerns the role of intra-and interspecific diversity of mycorrhizal fungi, which are critical for plant fitness, biogeochemical cycling and other processes. Here, we test the hypothesis that the identity and richness of ectomycorrhizal (ECM) fungi at the intra-and interspecific levels affect ecosystem multifunctionality by regulating plant and fungal productivity, soil CO2 efflux and nutrient retention.
