Plant-plant interactions and coexistence can be directly mediated by symbiotic arbuscular mycorrhizal (AM) fungi through asymmetric resource exchange between the plant fungal partners. However, little is known about effects of AM presence on allocation in mixed stands. Here, we examined how phosphorus (P), nitrogen (N) carbon (C) resources were distributed coexisting con- heterospecific individuals or absence fungus, using radio- stable isotopes. Congeneric species,
