Host tree diversity as drivers of ectomycorrhizal richness.

Recent correlative analyses suggest that host phylogenetic composition may be an important determinant of ectomycorrhizal fungal richness, with communities of higher host phylogenetic richness hosting a greater number of ectomycorrhizal fungal species. To mechanistically assess this relationship, we applied a field experimental approach in which host phylogenetic diversity was manipulated, from no phylogenetic diversity (monoculture) to medium phylogenetic diversity (gymnosperms vs. angiosperms) and high phylogenetic diversity (North American vs. European). We assessed ectomycorrhizal fungal richness by using Illumina sequencing. Our results indicate that there is a relationship between host phylogenetic diversity and ectomycorrhizal fungal richness, and that there is some signal of host origin and ectomycorrhizal richness.
