The study’s main finding was an asymmetric outcome of the interaction between arbuscular mycorrhizal (AM) and ectomycorrhizal (EcM) plant species: while Hieracium caespitosum and associated AM fungi reduced the abundance of EcM fungi in soil, modified the composition of EcM fungal communities, and also tended to decrease growth and mycorrhizal colonization of Betula pendula seedlings, the EcM host did not have such effects on AM plants and associated AM fungi. In the context of primary succession, these findings suggest that ruderal AM hosts could hinder the development of EcM tree seedlings, thus slowing the transition from AM-dominated to EcM-dominated vegetation in early successional stages.
